The 2026 Electrical Contracting Business Valuation & EBITDA Multiples Guide

Joe Lewin · Founder, DealFlowAgent · LinkedIn Published April 2026 · Updated July 2026

Electrical contracting is being repriced by two forces at once: data centres and statutory compliance. In the US, five electrical prints above $300M landed in eighteen months, every one pitched on data centre demand: MasTec agreed ~$1.65bn for The Superior Group in July 2026 at roughly 6.7x forward EBITDA, Dycom paid $1.95bn for Power Solutions at ~9.7x, EMCOR paid $865M for Miller Electric, Sterling paid $505M for CEC at ~9.6x, and MYR Group agreed $328M for Valley and Comet. In the UK the story is compliance and grid: PTSG, backed by Macquarie, bought two national fixed wire testing businesses inside ten months, Renew Holdings disclosed three high-voltage electrical acquisitions through its RNS (rare public multiples: roughly 4x to 10x EBITDA depending on niche), and Sureserve paid £56.4M for Kinovo's electrical-led compliance group. Behind the UK compliance lane sits a statutory event with a date: every existing social housing tenancy in England must hold its first EICR by 1 November 2026, roughly four million homes entering a five-yearly testing cycle, with penalties up to £40,000.

What that competition pays. Prepared, professionally represented UK electrical businesses with £1M+ of defended EBITDA are transacting between roughly 4x and 7.5x, with recurring testing and maintenance revenue the strongest lever and data centre, high-voltage and compliance exposure repricing businesses well above the trade's install-led norm. Platform-grade groups above £3M of EBITDA reach 5.5x to 8.5x, and the disclosed prints run higher where scarcity bites (HV design at ~10x; US data centre contractors at 6.7x-10.6x). Below £1M of earnings the ranges step down honestly, because electrical contracting carries the weakest published small-end multiples of the building trades, and this page does not pretend otherwise. Every market figure carries a named, dated source; our own figures are labelled DealFlowAgent data.

Why two businesses with the same EBITDA sell for very different prices

Before any table of multiples, the point most owners miss. Take two electrical businesses, each showing £600K of EBITDA. The first earns it as a new-build subcontractor: tendered packages for three main contractors, revenue re-won from zero every year, margins set by the lowest bidder, cash strangled by retentions and applications for payment, and work-in-progress accounting that no two people in the business reconcile the same way. The second earns the same £600K from EICR programmes, emergency lighting and PAT testing across landlord portfolios and social housing frameworks, plus reactive maintenance on term contracts: statutory five-yearly cycles that clients are legally required to keep buying, invoiced monthly, with a compliance deadline in November 2026 pushing demand at the sector faster than it can hire. The first will struggle to clear 3.5x. The second can defend 5x or better, and the consolidators in the deal tables below, one of which has bought two national testing businesses in ten months, will compete for it. Same EBITDA, roughly £900K apart, and every pound of the difference is explained by things the owner can influence.

Throughout this page we keep three revenue mixes separate, because buyers price them on different evidence: testing, compliance and maintenance (recurring, statute-driven, the premium asset), contracting and installation (project work, priced lower because it must be re-won and its WIP must be believed), and residential/domestic services (a different buyer universe, labelled wherever its data appears).

Five moves that raise the multiple before you sell. (1) Build or buy a testing and compliance arm and convert habitual clients onto term maintenance agreements: recurring revenue is what separates the two businesses in the story above; (2) get WIP, applications and retentions onto one consistently applied policy with a monthly reconciliation, because the first thing a buyer's accountants attack in this trade is revenue recognition; (3) measure gross margin by work type (testing, maintenance, small works, projects) and stop quoting projects that only look profitable before overhead; (4) evidence a second tier, including a qualifying supervisor who is not you, so consideration stays as completion cash; (5) have your EBITDA bridge defended to quality-of-earnings standard before the first buyer conversation. None of these requires new customers; together they are routinely worth more than a year of trading growth.

What is an electrical business worth in 2026? The master table

The ladder is banded by defended EBITDA, the number buyers actually price (owner-operated businesses below roughly £250K of earnings price on SDE, covered beneath the table). Ranges are the DealFlowAgent tier view, calibrated against the published evidence cited per band and the 2025-2026 transactions in the deal tables; no institutional source publishes UK electrical multiples by size band, so treat this as calibrated judgement anchored to named sources, not a price list. The lower bound describes an unprepared, install-weighted subcontractor sold without competition; the upper bound a prepared, professionally represented business with strong recurring testing and maintenance revenue. The factor framework moves a business between the two. Be aware the small-end floors here sit below the equivalent HVAC, security and fire ladders: the published data (BizBuySell's 2.66x SDE median, Peak Business Valuation's 3.2x-4.0x EBITDA) is simply weaker for this trade, and flattering you here would fail you in diligence.

**Indicative revenue assumes the roughly 6-12% EBITDA margins we see in UK electrical businesses at each size, compliance-led books at the top of that span (DealFlowAgent estimate from mandate work and filed accounts; no public source publishes UK electrical margins by turnover band; for calibration, CFMA's 2025 US specialty-trades benchmark shows 7.7% net income before tax and Cascade Partners' listed electrical comps median a 10.5% EBITDA margin). Multiple ranges: DealFlowAgent tier view calibrated against the sources cited per band and the linked deal tables.

Below £250K of earnings: owner-operated businesses price on SDE, typically 2.0x-3.0x. Published US floors: BizBuySell's 266 sold electrical and mechanical businesses median $950K price at 2.66x SDE; DealStream's rules of thumb run 2.0x-3.0x SDE (broker convention, not transaction data). Read them as floors: a UK business with NICEIC registration, a testing book and a second qualified supervisor carries scarcity those medians do not capture. The size ladder covers the routes up.

How electrical businesses are actually valued

Defended EBITDA, not claimed EBITDA, and why WIP is where it dies

Enterprise value equals adjusted EBITDA times a multiple, and in electrical contracting the first number is contested harder than in any other building trade, because so much of it flows through work-in-progress. Under-billed WIP that turns out to be unrecoverable, over-billed positions masking losses to come, applications for payment recognised as if certain, retentions carried as if collectable: every buyer's quality of earnings team has seen each of these flatter an electrical P&L, and they arrive assuming yours does too. The number that survives their review is defended EBITDA, and the way to defend it is decided long before diligence: one revenue recognition policy, applied consistently, reconciled monthly, with a contract-by-contract WIP schedule that ties to the accounts. A seller who hands over that schedule on day one is telling the buyer the rest of the data room can be trusted; a seller who cannot is inviting the re-trade. The same logic covers add-backs (one-off, personal, documented, or they fail) and the two cash questions specific to this trade: retentions (how much, how old, how collectable) and the seasonal working capital pattern a peg will be set against. Bring 24 months of monthly working capital data and you set the peg; arrive without it and you accept the buyer's.

The multiple is a quality score

Two electrical businesses with identical earnings routinely transact more than a full turn apart. The buyer's investment committee is scoring: how much of the revenue recurs on statutory cycles, whether the WIP can be believed, what happens when the founder and qualifying supervisor leaves, how concentrated the book is in a few main contractors, and how many credible bidders are at the table. Section five breaks that judgement into the 30 factors.

Below roughly £250K of earnings: SDE, not EBITDA

An owner on the tools is priced on seller's discretionary earnings: profit plus the owner's full compensation, on the basis the buyer works in the business. Published guidance puts the switch to EBITDA-basis pricing around $1M of earnings; buyers start deducting a manager's replacement salary well below that. The honest small-end evidence for this trade is thin and US-weighted, and it is lower than owners expect: 2.66x SDE median across 266 closed deals. The route up is the same as everywhere on this page: contracted testing and maintenance revenue, a second qualified supervisor, and clean separation of personal costs.

How recurring testing and maintenance books are priced: the honest answer

No published dataset quantifies the premium for recurring electrical revenue, and we will not invent one. What the evidence supports is the direction and rough scale: US aggregator data shows new-construction-dependent contractors pricing around 4x against roughly 6x for service-heavy businesses; the UK's most acquisitive electrical buyer, PTSG, has built its entire electrical division on fixed wire testing acquisitions, the definition of recurring statutory revenue; and the sharpest disclosed UK contrast comes from one listed buyer's own RNS filings: Renew paid roughly 4.1x initial EBITDA for an overhead-line maintenance business and roughly 10x initial for a scarce high-voltage design consultancy seven months later. Same acquirer, same sector, two and a half turns apart: niche quality and scarcity set the price. In our own processes, a business with 30-40%+ of revenue on recurring testing and term maintenance prices at or above the top of its band on the master table, and an install-only business with the same earnings prices at or below the bottom (DealFlowAgent data). There is no separate per-book multiple in this trade, unlike security monitoring; the premium expresses through the EBITDA multiple, which is why building the recurring book is the highest-yield preparation an electrical owner can do.

The size ladder, band by band

Each band states the evidence behind its range, who transacts there, and what changes crossing in. The published base for electrical is the weakest of the building trades at the small end and dominated by data-centre-driven prints at the top; where a figure is US, residential or public-market we say so. The strongest cross-checks are Dealsuite's UK&I all-sector size curve (3.3x at £200K of EBITDA to 8.4x at £10M), Capstone's construction-services averages (strategic buyers 7.5x, PE 10.6x, disclosed deals 2018-2025), and the disclosed UK prints in the deal table.

Below £250K earnings: the owner-operator band

2.0x-3.0x SDE (DealFlowAgent view; US floors: BizBuySell 2.66x SDE median, $950K median price; Peak Business Valuation SDE 2.22x-2.89x, main-street appraiser data). Transferability decides everything: a testing book on statutory cycles, a second qualified supervisor and scheme registration that survives the owner's exit move a sale from asset value to a genuine multiple.

£250K-£500K defended EBITDA: professional buyers arrive

2.5x-4.0x, testing and compliance books to 4.5x (DealFlowAgent tier view; anchors: Peak's 3.2x-4.0x EBITDA small-company range; DealStream's 3.0x-5.0x broker convention; the Dealsuite curve starting at 3.3x around £200K, all-sector). What changes crossing in: accounts get read by professionals, WIP credibility starts costing real money, and the testing-versus-install mix becomes the dominant pricing question.

£500K-£1M defended EBITDA: the compliance consolidators' range

3.0x-5.0x, recurring testing books to 5.5x (DealFlowAgent tier view; anchors: the Dealsuite curve passes 4x-5x here on all-sector terms; ClearlyAcquired's US curve puts small firms at 2.55x-2.71x rising through 4.1x-5.0x for mid-size). This is where the UK's compliance buyers hunt: PTSG bought two national testing businesses in this bracket-and-above inside ten months, and Amcomri picked up a £5M-revenue testing carve-out. Because statutory demand is about to outrun capacity (the November 2026 EICR wall below), prepared testing businesses in this band are meeting the deepest demand they have ever had.

£1M-£2M defended EBITDA: the institutional threshold

4.0x-6.0x (DealFlowAgent tier view; anchors: IBBA's all-sector 4.1x for $2-5M deals as the US floor; the mid Dealsuite curve; the cleanest UK print in this earnings bracket, Renew's ~4.1x initial for Emerald Power at £1.9M EBITDA, a field-maintenance business bought without a competitive process, sits exactly at this band's floor and is the best public illustration of what an uncontested sale prices at). Crossing £1M switches on institutional size screens and acquisition debt; buyers begin pricing your second tier and your systems, not just your order book.

£2M-£3M defended EBITDA: management depth gets priced

4.5x-6.5x (DealFlowAgent tier view; anchors: IBBA $5-50M at 5.5x; Capstone's 7.5x strategic-buyer average marking where well-sold businesses head). A buyer here is buying an organisation: a contracts manager, a compliance division head, a qualifying supervisor who is not the founder, and WIP reporting a diligence team can query. The same EBITDA with that tier evidenced carries up to two turns more than the founder-run version.

£3M-£5M defended EBITDA: platform grade

5.5x-7.5x (DealFlowAgent tier view; anchors: the Dealsuite curve reaching 8.4x at £10M; Capstone PE average 10.6x on disclosed construction-services deals, larger and US-weighted). Platform grade: funds underwrite businesses of this size as the foundation of a buy-and-build, the way Truelink underwrote Prime Electric in the US, and pay for the management, systems and certification stack that bolt-ons integrate into. UK platform demand is visible in Tendra hiring a dedicated head of M&A and OCU's dozen acquisitions.

£5M-£10M defended EBITDA: print territory

6.5x-8.5x (DealFlowAgent tier view; anchors: US disclosed prints Sterling/CEC ~9.6x, Dycom/Power Solutions ~9.7x and MasTec/Superior ~6.7x forward, all data-centre-driven; UK compliance print Marlowe at 11.2x at larger scale). Deals here make the trade press with numbers attached, and the niche sets the premium: data centre and mission-critical exposure, HV scarcity and statutory compliance books all price above general contracting.

£10M+ defended EBITDA: institutional demand, thin UK evidence

7.5x-10x+, niche-dependent, and we say plainly: UK evidence at this size is thin. Reference points are triangulation: the US prints above (6.7x-10.6x, data-centre-pitched); EMCOR/Miller at 10.6x per Capstone; the compliance lane's Marlowe print; and the listed comps, which mark sentiment, not achievable private prices (EMCOR ~18x, IES Holdings ~25x, Comfort Systems ~35x TTM EV/EBITDA in July 2026, all inflated by the data centre bull market; apply no direct read-across). A UK electrical group at this size transacts on process, niche and structure, not on a table.

The 30 factors that set your multiple

Two identical P&Ls can transact two turns apart, because buyers price the characteristics that determine whether the P&L repeats under their ownership. The framework below is how we structure that judgement on DealFlowAgent mandates (DealFlowAgent framework; weights are our house view of buyer attention in this trade, not a published standard). Deal Process & Buyer Access carries the same weight as Financial deliberately: it is the only dimension a seller fully controls in the final twelve months.

Dimension 1: Financial (22%)

Dimension 2: Customer & Revenue (16%)

Dimension 3: Operations (14%)

Dimension 4: People & Organisation (13%)

Dimension 5: Strategic (13%)

Dimension 6: Deal Process & Buyer Access (22%)

The 27% figure. Across DealFlowAgent processes, a competitive, multi-buyer sale has produced an average uplift of 27% against the opening offer (DealFlowAgent data). Most of that uplift is the sixth dimension at work: the same business, better sold.

Two worked examples, with the arithmetic shown

Example one: the same £750K, priced £1.9M apart

Two UK businesses, each with £750K of defended EBITDA, both in the £500K-£1M band (3.0x-5.0x, recurring testing books to 5.5x).

Business A is a new-build subcontractor: three main contractors are 70% of revenue, WIP is reconciled annually at best, retentions are aged, and the founder holds the NICEIC qualifying supervisor position. Approached directly by one buyer, it prices at the bottom of the band:

£750,000 × 3.0 = £2,250,000

Business B earns the same £750K with 40% of revenue from EICR programmes, emergency lighting testing and term maintenance across landlord and social housing clients, monthly WIP reconciliation, a second qualifying supervisor, and margins reported by work type. Taken to market with four bidders held in parallel, it prices where recurring testing books reach:

£750,000 × 5.5 = £4,125,000

Same earnings, £1,875,000 apart. Every element of the difference (recurring share, WIP discipline, qualification succession, concentration, process) is a factor from the framework above, and all of it is buildable in the one to three years before a sale.

Example two: £2M of EBITDA crossing the platform boundary

An electrical business with £2M of defended EBITDA sits at the top of the £1M-£2M band. Sold well, as a good bolt-on:

£2,000,000 × 6.0 = £12,000,000

The same business eighteen months later, having grown defended EBITDA to £2.4M, built out its compliance division to a third of revenue, and been positioned to funds as a platform seed for a testing-and-maintenance buy-and-build, prices in the next band's upper reaches:

£2,400,000 × 6.5 = £15,600,000

Of the £3.6M difference, £2.4M is the extra earnings at the old multiple; the remaining £1.2M is multiple expansion from crossing the boundary with the characteristics platforms pay for. At £1.5M-£2M of EBITDA, the highest-value project is usually the compliance division and the management hire, not the next contract award.

2025-2026 transaction evidence: UK

Every row is a verified UK or Ireland electrical transaction announced January 2025 to July 2026, with a clickable source. An honest note on what this table can and cannot show: UK electrical deal flow concentrates in three lanes (high-voltage and power infrastructure, electrical compliance and testing, and electrical-led M&E platforms), and the disclosed numbers cluster in the HV lane because listed buyers must file them. Pure commercial fit-out contractors transact largely undisclosed or off-market, so published multiples over-represent grid-driven premiums; read the lanes, not an average.

What this table says when read together. First, the only clean disclosed multiples in UK electrical M&A come from one listed buyer's RNS filings, and they bracket the whole quality argument of this page: Renew paid roughly 4.1x initial EBITDA for field-labour maintenance and roughly 10x initial for scarce HV design capability within seven months. Where your business sits between those two prices is set by the factors above, not by the trade you are in. Second, the compliance lane has a dedicated consolidator: PTSG has now assembled four electrical testing businesses, and Amcomri's nominal-consideration carve-out shows the same appetite reaching distressed sellers; with the social housing EICR wall four months away, testing capacity is the asset in shortest supply. Third, earn-outs are standard here: 25-37% of total consideration in all three disclosed Renew deals, tied to vendor retention and profit targets, which is why the deal structure section below matters as much as the headline number.

2025-2026 transaction evidence: US

The US market runs on one engine: data centres. Every large print of the window is pitched on mission-critical electrical capacity, and an honest structural note belongs up front: the residential roll-up pattern that defines US HVAC does not exist at comparable scale in electrical. Residential electrical trades as a service line inside multi-trade home services platforms, not as standalone platforms, so the table below is commercial, industrial and infrastructure-weighted, labelled by lane.

What this table says when read together. The pricing story is remarkably consistent: disclosed data-centre-pitched electrical deals printed between roughly 6.7x and 10.6x EBITDA and 0.8x-1.9x revenue, against a published 7.5x strategic-buyer average for construction services generally. The buyers split into three groups, all still hungry: listed strategics filling capacity gaps (MasTec, Dycom, EMCOR, Sterling, MYR, Quanta, Comfort Systems), new PE platforms in commercial electrical and electrical testing (Truelink/Prime, Platte River/Team UIS, Searchlight/IPS, Kohlberg/Loenbro, Apollo/State Group), and multi-trade consolidators adding electrical as a line (Del-Air). The read-across for UK owners is the demand driver, not the multiple: the same data centre build-out is arriving in the UK (see below), and the US shows what buyers pay when electrical capacity becomes the bottleneck to it. Behind it all sits $49.5bn of US data centre construction starts in the four months to April 2026, against $13.6bn in the same period of 2025.

2026 demand drivers and the consolidation map

Buyers pay premium multiples when demand is statutory or structural. Electrical currently has the strongest statutory story in UK building services, and each driver below is verified against a primary source as of July 2026.

The EICR wall: 1 November 2026

The private rented sector has needed five-yearly electrical installation condition reports since 2020 (remedials within 28 days, penalties to £30,000). What changes everything is SI 2025/1043: the same duties extended to social housing, in force from 1 November 2025 for new tenancies, with every existing social tenancy in England required to hold its first EICR by 1 November 2026 and penalties raised to £40,000. Roughly four million social homes are entering a permanent five-yearly testing cycle, procured at scale through housing association and local authority frameworks, and as of this update the sector is four months from the deadline with capacity already short. Layered on top, Awaab's Law phase 2 is expected from October 2026 to put statutory investigation and repair clocks on electrical hazards in social housing, which makes responsive electrical repair capability a procurement requirement, not a nice-to-have. For contractors this is the strongest recurring statutory demand event in the trade; for buyers, an EICR-and-remedials book with framework access is precisely what PTSG, Amcomri and Sureserve have been buying. Scotland (since 2015) and Wales (since 2022) already run equivalent cycles. One honest caveat: no official compliance statistic is published for the PRS regime, so claims about current compliance rates are estimates and we do not quote one.

BS 7671 Amendment 4:2026: the whole trade requalifies

The IET and BSI published Amendment 4 to the 18th Edition Wiring Regulations on 15 April 2026, with the previous version withdrawn around October 2026 and no 19th Edition announced. A4 adds battery storage provisions, ICT earthing and medical locations, following A3:2024's bidirectional-device rules for solar and battery prosumer installations. The commercial mechanism: every qualified electrician requalifies, design libraries update, and the fast-growing solar, battery and EV work is pulled formally inside core wiring-regs competence, advantaging businesses whose training matrices are current.

Electrification demand: solar records, EV resets, grid reform, data centres

The demand stack behind UK electrical work in 2026: a record 203,125 MCS-certified solar installations by mid-November 2025 with battery installs up 122%; EV charge point grants reset from April 2026 at up to £500 per socket, running to March 2027, though note public chargepoint additions slowed in 2025 (+13,281 versus +24,557 in 2024), so this is a steady lane, not a gold rush; NESO's connections reform went live in December 2025, prioritising 283GW of projects and unblocking commercial schemes; and the UK data centre pipeline has 29 consented projects expected to start construction in 2026 with 246 more at pre-tender. Each lane rewards a different capability, which is why the factor framework scores electrification position explicitly.

Labour: the binding constraint

The ECA reported in February 2026 that electrical apprenticeship starts fell 5.5% while national apprenticeships rose, with Skills England estimating 12,000 more electricians needed by 2030 and fewer than one in five classroom learners progressing into apprenticeships. In the US, BLS projects 9% growth and roughly 81,000 electrician openings a year to 2034. Both point the same way for valuation: a JIB-graded bench with an apprentice pipeline is itself an acquired asset, and wage inflation punishes contracts without indexation.

US read-across, including the honest headwind

US data centre electrical demand explains the premium prints above. But US residential electrical now carries a documented headwind: the One Big Beautiful Bill Act terminated the 25C and 25D residential energy credits after 31 December 2025, and the 30C EV charger credit after 30 June 2026, so 2025 US residential comparables contain pull-forward demand that will not repeat. UK owners reading US commentary should adjust accordingly; UK statutory demand (EICR, Awaab's) has no such cliff, it is only beginning.

The consolidation map: who is actually buying

UK and Ireland, verified active 2025-2026: PTSG (Macquarie, Warburg Pincus minority; the fixed wire testing consolidator), Renew Holdings/Excalon (listed; three HV deals in eight months, discloses numbers), OCU Group (Triton; ~12 acquisitions, £295M to £886M revenue in two years), Tendra (Triton; dedicated head of M&A appointed July 2026), Sureserve (Cap10; electrical arm via Kinovo), United Infrastructure (Apollo Impact), Ipsum (IK Partners), Suir Engineering (Duke Street), Amcomri (AIM), STRABAG UK, NG Bailey, Complii (serial electrical-testing buyer historically), M Group (PAI; a credible buyer via its BGEN M&E base). US: MasTec, Dycom, EMCOR, Sterling, MYR, Quanta, Comfort Systems on the listed side; Truelink (Prime Electric), Searchlight (IPS), Platte River (Team UIS), Kohlberg (Loenbro), Apollo (State Group), Stellex (ICS), ArchKey, Paceline (TRIO) among sponsors.

What kills the multiple

The mirror image of the factor framework: the six findings that most reliably cut offers in this trade, written as the buyer's investment committee actually reasons.

1. WIP that cannot be believed. "Under-billings jumped 40% in the final year and nobody can reconcile the contract schedule to the accounts. Either profit was pulled forward or losses are parked; both mean the EBITDA is not what we were shown. Price down, or walk." Revenue recognition is the single most common diligence killer in electrical deals, and it is entirely preventable.

2. Main contractor concentration on onerous paper. "Two main contractors are 60% of revenue on pay-when-paid terms with unlimited damages. Our downside is their solvency and their programme, not this management team's competence. We price the whole business as if the next Carillion is in the book." Direct client and framework revenue is worth more than the same turnover through a main contractor, every time.

3. No recurring testing arm. "Everything must be re-won. There is no EICR book, no term maintenance, no framework place. We are buying a bid team and a labour force, so we pay contractor prices, not annuity prices." Install-led businesses price toward the bottom of every band on the master table.

4. The founder as qualifying supervisor. "The NICEIC registration, the biggest client relationships and the estimating judgement all sit in one person who wants to leave. The business we are buying degrades the day they stop, so the structure will hold them: bigger earn-out, longer handcuffs, less cash at close." Qualification succession is the cheapest multiple protection in the trade.

5. Retentions and cash nobody manages. "There is £400K of retentions on the balance sheet, half of it aged past contractual release, some owed by insolvent contractors. That is not working capital, it is a write-off we are being asked to pay for." An aged, chased, honestly provided retention ledger converts a diligence fight into a footnote.

6. Fragmented records. "Certificates in filing cabinets, test results in three formats, job history in one contract manager's memory. We cannot verify the compliance book we are paying a premium for without rebuilding it." Buyers pay for what they can verify; a queryable certification system is worth real money at exit.

Deal structure by size: headline price versus cash at close

The multiple sets the headline; structure decides what you bank. Published evidence: small US deals complete at 76-89% cash at close, seller notes 9-14%, earn-outs used sparingly (IBBA, all sectors); mid-market earn-outs featured in 24% of 2025 US private deals (SRS Acquiom) and 27% of European deals, the equal-highest recorded (CMS), with 39% of UK advisers reporting increased earn-out usage (Dealsuite). In UK electrical specifically the disclosed evidence is blunt: all three Renew RNS deals carried earn-outs of 25-37% of total consideration tied to vendor retention and profit targets, and you should assume a structured offer, not a clean one, unless competition removes it. Trade-specific structure points: the working capital peg must handle retentions and WIP explicitly (agree the treatment in the letter of intent, including how aged retentions are valued); project businesses attract completion accounts rather than locked box; and rollover equity in platform deals typically runs 10-30% of proceeds (adviser consensus; no primary dataset, house view). Our standing advice: negotiate structure as hard as price. The levers that keep consideration in cash at close (recurring revenue, qualification succession, believable WIP, a live underbidder) are the same ones the factor framework scores.

UK versus US: what actually differs

Three implications for a UK owner. First, the UK's statutory story is stronger than America's right now: US residential lost its tax tailwind while UK social housing gained a compliance wall with a date; a UK testing-led business is selling into improving demand, and should time and position accordingly. Second, scheme registration is transferable value: because NICEIC/NAPIT registration and framework places sit at company level, a clean certification stack transfers with the shares, where US licences held through individual qualifiers often do not; evidence qualification succession and you remove the buyer's favourite discount. Third, data centre capability is the premium ticket on both sides of the Atlantic: the US prints show 2-4 turns of premium for mission-critical electrical capacity, the UK pipeline is now consented and starting, and a UK contractor with HV, containment or critical-power credentials should make sure every buyer in the process knows it.

How much is my electrical contracting business worth in 2026? UK electrical businesses are priced on defended EBITDA. Businesses between £250K and £2M of EBITDA typically transact between 2.5x and 6.0x depending on size, revenue mix and process, with recurring testing and compliance books at the top of each range and install-led subcontractors at the bottom. Above £3M of EBITDA, platform-grade businesses reach 5.5x to 8.5x, and specialist niches (high voltage, data centres, compliance) price above general contracting. Owner-operated businesses below roughly £250K of earnings price on SDE, typically 2.0x-3.0x.

What multiple do electrical companies sell for? Most UK small and mid-sized electrical businesses sell between 2.5x and 6.0x EBITDA. The published evidence is honest but unflattering at the small end (US closed-deal data medians 2.66x SDE), and the premium is earned by mix: the same acquirer paid roughly 4x for field maintenance and roughly 10x for scarce high-voltage design within seven months. US data-centre-driven prints ran 6.7x to 10.6x in 2025-2026.

How do buyers value EICR and compliance testing contracts? Through the EBITDA multiple, as a quality premium: no separate per-book multiple is published for electrical testing. A business with 30-40%+ of revenue on statutory testing cycles and term maintenance prices at or above the top of its size band, because the revenue recurs by law. Demand is rising: every existing social housing tenancy in England must hold an EICR by 1 November 2026, bringing roughly four million homes into a permanent five-yearly cycle.

What is the November 2026 EICR deadline and does it affect my business's value? SI 2025/1043 extends the electrical safety regime to social housing: new tenancies from 1 November 2025, and all existing tenancies must have their first EICR by 1 November 2026, with penalties up to £40,000. For contractors with testing capacity and framework access it is the strongest statutory demand event in the trade; buyers are already consolidating the space, so a positioned business is worth more now than its trailing numbers alone suggest.

Why do electrical businesses sell for less than HVAC or fire businesses? On average they carry less recurring revenue: install and project work dominates the trade, must be re-won annually, and exposes buyers to WIP and main-contractor risk. The gap closes, and reverses, for electrical businesses with statutory testing books, term maintenance, HV scarcity or data centre exposure. The ladder on this page shows exactly where the premium sits.

What kills electrical deals in due diligence? Work-in-progress. Under-billed or over-billed positions that do not reconcile, applications recognised as certain revenue, and aged retentions carried as collectable are the most common reasons electrical offers get re-traded or die. One revenue recognition policy, applied consistently and reconciled monthly, is the cheapest protection of value in this trade.

Should I sell my electrical business now? The demand backdrop is the strongest the trade has had: a statutory compliance wall in social housing, grid investment, a consented data centre pipeline and an electrician shortage that makes qualified benches scarce assets. Buyers are funded and active across all three lanes. Preparation is the deciding variable: recurring revenue, believable WIP, qualification succession and a competitive process capture the top of the band.

How long does a sale take? Typically 6 to 12 months from launch to completion. The two biggest schedule risks in this trade are both preventable: a WIP schedule that fails quality-of-earnings review, and missing compliance records buyers must reconstruct. Sellers with the data room ready before launch routinely complete a quarter faster.

Glossary

• Applications for payment: staged invoicing under construction contracts; recognised revenue only when certified, a core WIP risk.
• Awaab's Law: statutory repair timeframes in social housing; phase 2 (expected Oct 2026) covers electrical hazards.
• BS 7671: the IET Wiring Regulations, 18th Edition, currently amended by A4:2026.
• Competent person scheme: registration (NICEIC, NAPIT) allowing self-certification of notifiable domestic work under Part P.
• Defended EBITDA: the adjusted EBITDA that survives a buyer's quality-of-earnings review; the number that gets priced.
• Earn-out: deferred consideration contingent on post-completion performance; standard in disclosed UK electrical deals (25-37% of consideration in recent RNS examples).
• EICR: electrical installation condition report; statutory five-yearly in the private rented sector and, from November 2026, across all English social housing.
• Enterprise value (EV): the whole-business price before cash, debt and working capital adjustments.
• Framework / DPS: pre-qualified procurement routes (frameworks, dynamic purchasing systems) that gate public-sector and housing revenue.
• HV: high voltage; UK contracting above 1kV, where scarcity currently commands the trade's highest disclosed multiples.
• JIB: the Joint Industry Board grading framework for electrician qualifications and pay.
• NETA testing (US): independent electrical acceptance and maintenance testing, the US cousin of the UK compliance lane.
• NICEIC / NAPIT: the main UK certification and competent person scheme bodies for electrical contractors.
• Part P: the Building Regulations requirement governing notifiable domestic electrical work in England and Wales.
• Qualifying supervisor: the named qualified person on whom a contractor's scheme registration depends; succession is a valuation factor.
• Retentions: contract sums withheld pending defect periods; their age and collectability are priced in every electrical deal.
• Rollover equity: the portion of proceeds a seller reinvests into the acquiring platform, typically 10-30%.
• SDE: seller's discretionary earnings; profit plus the owner's full compensation, the small-business pricing basis.
• WIP: work in progress; the contract-by-contract position between cost incurred and revenue billed, the heart of electrical diligence.
• Working capital peg: the agreed normal working capital delivered at completion; in electrical it must handle WIP, applications and retentions explicitly.
