Active Acquirers in London Region
London accounts for 20% of all UK construction projects and the pipeline is accelerating. The Fire Safety (Residential Evacuation Plans) Regulations, enforced from April 2026, are creating a compliance surge that directly benefits fire safety contractors with existing residential portfolios. The London Growth Plan — the Mayor's economic framework through 2030 — prioritises retrofit, decarbonisation, and affordable housing, generating sustained demand for HVAC, insulation, and energy efficiency contractors. The Canary Wharf residential pivot, Nine Elms completion, and Old Oak Common development represent billions in construction spend requiring specialist building services support.
What London Business Owners Are Going Through
London building services owners face the most intense labour competition in the UK. The combination of Crossrail completion programmes, HS2 Euston, and the £1.5 billion Q2 2026 project pipeline means skilled engineers command premium wages that squeeze margins for SME contractors. Commercial rent increases across Greater London — up 12% on average since 2023 — add further cost pressure. The Building Safety Act's full implementation is imposing new dutyholder responsibilities that require additional compliance infrastructure, increasing overheads for fire safety and building management contractors. Many London owners tell us they are working harder than ever but keeping less — the classic pre-exit signal.
PE and Acquirer Activity in London
London has the highest concentration of PE-backed building services platforms in the UK. Marlowe plc, Facilities by ADF, and Sureserve Group all maintain active acquisition mandates across Greater London. The fire safety sub-sector has seen particularly aggressive consolidation following Grenfell, with multiple platforms competing for compliant contractors with residential maintenance books. In healthcare, London's dental market is the most competitive for acquirers, with Portman Dental Care, Bupa Dental, and several PE-backed groups all seeking practices across the capital. For London business owners, this concentration of buyer interest typically translates into competitive processes that drive premium valuations.

For London-based businesses, we typically generate interest from both domestic acquirers and international buyers attracted to the London market.
What is the typical valuation multiple for building services businesses in London?
Valuation multiples for London building services businesses vary significantly by sub-sector, recurring revenue mix, and contract quality. Businesses with strong recurring maintenance contracts and compliance-driven revenue streams typically command premium multiples. DealFlowAgent runs a competitive process with multiple buyers to ensure you achieve the highest possible valuation for your business.
Do I need to be based in London to use DealFlowAgent?
No. While we have deep expertise in the London market, DealFlowAgent advises business owners across the entire UK and the United States. Our buyer network is national and international, so your business will be marketed to the most relevant acquirers regardless of where they are based.
How long does it take to sell a business in London through DealFlowAgent?
A typical M&A process takes between four and nine months from engagement to completion. London businesses often attract strong buyer interest quickly due to the concentration of acquirers in the region. DealFlowAgent manages the entire process from valuation and marketing through to negotiation, due diligence, and completion.

Close & Protect the Legacy
A senior M&A bench, plus a sector specialist recruited for your industry on every deal.
For every engagement we add a sector specialist from your industry to the core team: a 15–25 year operator or advisor with direct relationships in your niche. Recruited per deal so you get the right fit, not a generalist.
"I built and sold my own company after scaling it to 80,000+ users and raising over £2M in funding. The exit process was painful, expensive, and completely opaque. I knew other business owners deserved better."
So I set out to modernise the way businesses are sold. We have now advised on 22 sales, built a network of over 12,500 registered acquirers, and we are the only AI-enabled M&A firm with this proprietary technology and data. We are highly specialised in building services, facilities management, and healthcare, and that is all we do.
Before DealFlowAgent, I spent years in the trenches of high-growth startups, learning what it takes to build, scale, and ultimately sell a business. That firsthand experience — the sleepless nights, the difficult conversations, the elation of getting it done — means I understand what our clients are going through on a level that most advisors simply cannot.
There is nothing better than a founder calling to say they have paid off their mortgage, sorted their children's school fees, or are ringing from a three-week holiday in the Maldives. That is why we do this.
On a personal note: 30 years old, grew up in Surrey, Crystal Palace supporter (sorry), and proud owner of Willow, an English Spaniel who is far more popular than I am. I also make a very good lasagne, if that helps.
Backed by institutional investors behind global industry leaders.
We have raised substantial private capital to ensure our advisory platform, proprietary buyer intelligence and client execution team have permanent, long-term balance sheet stability.

Here's how we deliver these results
Six factors that outperform a generalist broker. Each one delivers a measurable result — see the right-hand column.
Compounded, these six factors translate into the outcomes below.
Four years of direct conversation with sector acquirers — interviews, deal calls, sector dinners — layered with structured weekly buyer interviews via Sterling. Roughly twenty columns of intelligence per buyer: search criteria, valuation thresholds, deal structure, the management team they want to inherit, and the green, amber and red flags that move them.
We work in two verticals. Every advisor, every buyer profile, every comparable sits inside that focus. Specialists win against generalists at the table.
Funded to invest in marketing, events and full-page presence in Fire Safety Matters, Professional Security Magazine and International Fire Buyer. When a buyer receives our outreach about your company, they already know us.
Sage and Sterling give us live visibility on every buyer — open rates, replies, intent signals — across multi-channel outreach. Each pitch is personalised to the buyer's strategic priorities.
Optional, separate from the +27% above. The Diagnostic, Second Brain and AI Employees can lift EBITDA 0.5x to 2x in three to six months by unlocking growth, lifting margin and removing key-person dependency. That raises the multiple buyers will pay before we even take you to market.
The final 5 to 10 percent of the headline number is decided in the last two weeks. Our advisors have led the negotiation seat on twenty-plus closed deals. Anchoring, deal structure, earnout design and walk-away credibility are not improvised.
Joined full-time on 22 August 2026 from the largest M&A advisory firm in the UK, owned by K3 Capital. As an ex-Director he managed teams of M&A advisors, analysts and associates, working daily with business owners, buyers and stakeholders on live acquisition deals. Selected from 260 applicants alongside colleagues from investment banking backgrounds, he brings that experience and network to lead the advisory bench across Building Services, Facilities Management, and Healthcare.
Senior Building Services & FM Advisor
Martin is one of the most well-connected figures in UK fire, security, building services and FM. He is Chairman of both the Fire Industry Association and the British Security Industry Association, the only person in the UK to hold both roles simultaneously. Martin spent over a decade in senior leadership at Mitie, latterly as Industry Liaison Director for its fire and security division, helping scale the business past £500m in revenue and playing a role in the £366m acquisition of Marlowe plc, which created one of the UK's largest compliance, fire and security services groups. He joined DealFlowAgent because owners in these sectors deserve a genuine sector-specialist advisor across valuation, business optimisation and buyer access. In recognition of his industry roles, he acts in a personal, non-partisan capacity.
Industry Partner, Hiring and Leadership
Nick leads FM Talent Partners, the facilities management and real estate leadership search firm, and is a leading specialist in building services and FM management talent. He partners with DealFlowAgent on two-way referrals: helping business owners and acquirers fill the key roles that decide whether a business is sellable, and introducing owners who are thinking about their next chapter to a team that knows their industry and their market. Key-person dependency is one of the two most common reasons a sale collapses, and Nick fixes it at source.
