The 2026 Security Systems Business Valuation & EBITDA Multiples Guide

Updated: April 2026

If you own a security systems and integration company generating £1M to £50M in revenue, you have likely spent decades building your business. You have navigated the painful shift from analog to IP, managed the transition to cloud-based systems, dealt with the chronic technician shortage, and built a reputation for protecting your local community's most critical assets.

When it comes time to sell, it is not just about the headline valuation number. It is about securing the right deal terms. It is about maximizing the cash you receive upfront versus what is deferred or tied to performance earn-outs. Most importantly, it is about choosing the right buyer who will protect your legacy, take care of your team, and treat your clients with the same respect you have for years.

At DealFlowAgent, we are not generalist brokers. We are the leading specialist M&A advisory firm for the building services sector, operating via our Delaware corporation across the USA (starting in Florida and expanding nationwide) and throughout the UK. Backed by top-tier VC funding, we have built a dedicated team of sector-expert advisors and a proprietary network of over 12,000 registered acquirers. Because we understand the exact search criteria of these buyers, we can run highly competitive, multi-buyer sale processes. This competitive tension is the single most powerful way to secure not only the highest valuation but the best possible deal structure for your life's work.

But what is your security systems business actually worth today? And how do acquirers arrive at that number?

This guide breaks down the current EBITDA and RMR multiples buyers are paying in 2026, the specific operational levers that drive premium valuations, and actionable strategies you can implement today to systemise your business and maximize your exit value.

At a Glance: 2026 Security Systems Valuation Multiples

• £1M to £3M Revenue: 3.5x to 4.5x EBITDA (DealFlowAgent Premium: 4.4x to 5.7x)
• £3M to £10M Revenue: 5.0x to 6.5x EBITDA (DealFlowAgent Premium: 6.3x to 8.2x)
• £10M to £50M Revenue: 7.0x to 9.0x EBITDA (DealFlowAgent Premium: 8.9x to 11.4x)
• Key Value Drivers: >30% recurring revenue (RMR), commercial/enterprise focus, and advanced tech stack (Cloud/AI).

What is the 2026 M&A Landscape for Security Systems Businesses?

The security systems and integration M&A market in 2026 is experiencing a massive resurgence. It is a buyer's market for high-quality assets, where premium businesses with strong recurring revenue and cloud capabilities command multiple expansion, while lower-quality, installation-only firms face discounts [1] [2].

Consolidation is being driven by rapid technological advancement: the adoption of AI video analytics, the shift to Video Surveillance as a Service (VSaaS), and the modernization of legacy access control systems into cloud platforms [3]. According to Capstone Partners, security sector M&A surged 24.1% year-on-year in 2025, and that momentum has carried strongly into 2026 [4]. Active acquirers include PE-backed platforms like Pye-Barker Fire & Safety, strategic buyers like ASSA ABLOY, and massive global integrators [5].

For security founders, the window to secure a premium valuation is wide open, but buyers are increasingly selective. If you are considering an exit, now is the time to understand exactly how acquirers view your business and what levers you can pull to maximize your multiple.

What Are the Current Valuation Multiples for Security Companies?

Unlike tech startups valued on revenue, lower mid-market security businesses (£1M to £50M revenue) are valued using a hybrid approach. Buyers look at a multiple of Adjusted EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) for the overall business, but they place a specific, highly lucrative premium on RMR (Recurring Monthly Revenue) from alarm monitoring, cloud storage, and managed services [2].

Adjusted EBITDA normalizes your profitability by adding back one-time expenses, above-market owner salaries, and personal expenses run through the business, giving buyers a true picture of the cash flow they are acquiring.

Based on Q1 2026 transaction data and industry reports, here are the current EBITDA multiples for security systems businesses:

Note: The DealFlowAgent Premium reflects the average 27% valuation uplift achieved by running a competitive, multi-buyer process rather than negotiating directly with a single acquirer.

How do buyers value the RMR Premium?

In addition to the EBITDA multiple, buyers value recurring revenue streams separately:

• Monitoring & Managed Services RMR: Valued at 30x to 45x the monthly recurring revenue, depending on attrition rates and gross margins [2].

How Can I Build a Valuation Bridge from Baseline to Premium?

This is DealFlowAgent's signature framework. Median industry multiples are just a baseline. To achieve a premium valuation, you must build a "bridge" by optimizing specific operational factors that acquirers value most.

Here is how a standard security systems business moves from a baseline 4.0x multiple to a premium 6.5x multiple:

What Are Actionable Strategies to Systemise and Maximize Value?

Buyers do not just buy your cash flow; they buy your systems. If your business relies on your personal memory, paper diaries, or fragmented spreadsheets, buyers see risk. To command a premium multiple, you must demonstrate that your business is a scalable, systemised machine.

Here is a practical audit framework and strategy to implement over the next 6 to 12 months:

1. Implement Elite Field Service Management (FSM) Software

If you are still using whiteboards or basic accounting software to run dispatch and quoting, you are leaving money on the table. Buyers want to see a fully integrated FSM platform that handles complex project quoting, dispatch, inventory, and recurring billing in one place.

• For UK & Global Operators: We highly recommend SimPRO (DealFlowAgent is an official partner). It is exceptional for commercial security integrators, handling complex project management, recurring maintenance scheduling, and deep financial reporting.
• For US Operators: ServiceTrade and ConnectWise are industry standards. Buyers love seeing these because they know the data is reliable and the business is ready to scale.

2. The RMR Attrition Audit

Customer attrition is the silent killer of security company valuations. Buyers want to see annual RMR attrition rates below 8% (ideally below 5%). High churn indicates poor service or outdated technology.

• Action: Audit your current customer base. Calculate your exact gross and net attrition rates. Implement a systematic "save" process for any customer attempting to cancel a monitoring contract. If your attrition is high because of legacy 3G/4G sunset issues, prioritize upgrading those panels immediately.

3. Transition from "Install" to "Managed Services"

If you are just pulling wire and hanging CCTV cameras, you are a construction company, not a technology company. Buyers pay massive premiums for "Security as a Service."

• Action: Stop selling hardware outright where possible. Transition to selling Video Surveillance as a Service (VSaaS) and Access Control as a Service (ACaaS). Bundle the hardware, installation, cloud storage, and maintenance into a single, sticky monthly fee.

4. Build Second-Tier Management

The "Founder as Chief Salesman" problem is a massive valuation killer. If you are still running all the complex enterprise quotes or managing every major client relationship, you do not have a business; you have a job.

• Action: Over the next 12 months, systematically replace yourself. Hire or promote a dedicated Sales Manager and a Lead Engineer. Your goal is to make yourself operationally irrelevant. When a buyer asks, "What happens if you get hit by a bus tomorrow?" the answer must be, "The business runs exactly the same."

What Are the UK vs. USA Market Nuances for Security M&A?

While the core valuation drivers are similar, there are distinct differences between the UK and US markets that acquirers factor into their models:

The United States Market

• Consolidation Velocity: The US market is experiencing hyper-consolidation, driven by massive PE roll-ups (e.g., Pye-Barker Fire & Safety, APi Group). Buyers are aggressively seeking "platform" companies ($10M+ EBITDA) and smaller "bolt-on" acquisitions to build regional density.
• The VSaaS Boom: The US market is rapidly adopting cloud video and AI analytics. Integrators who have successfully partnered with platforms like Verkada, Eagle Eye Networks, or Brivo are commanding significant premiums.
• Union vs. Non-Union: Buyers carefully evaluate the labor model. Non-union (merit shop) contractors often attract a broader pool of PE buyers, while union contractors are typically acquired by strategic buyers who already operate within union frameworks.

The United Kingdom Market

• NSI Gold and SSAIB Accreditations: In the UK, holding top-tier accreditations (like NSI Gold or SSAIB) is non-negotiable for premium valuations, especially for commercial and public sector work. Buyers view these as essential moats that protect recurring revenue.
• The Convergence of Fire and Security: UK buyers are increasingly looking for "total life safety" providers. Security integrators who have successfully added fire safety capabilities (or vice versa) are highly sought after.
• Commercial Dominance: In the UK, commercial electronic security integration (especially in logistics, data centers, and high-end corporate offices) tends to see higher M&A activity and multiples compared to pure residential operators.

What Decreases the Multiple in an Acquirer's Teardown?

When Private Equity firms and strategic buyers look at your business, they are actively searching for reasons to lower their offer or structure the deal heavily toward earn-outs. Here are the top red flags:

1. Heavy Reliance on New Construction: Revenue tied to new builds is cyclical and highly sensitive to interest rates. Buyers will penalize firms where installation makes up more than 70% of revenue, preferring a balanced mix of service, upgrades, and RMR.
2. Customer Concentration: If a single general contractor or enterprise client accounts for more than 15% to 20% of your revenue, buyers will view the loss of that client as a catastrophic risk, often resulting in a lower multiple or a strict earn-out structure.
3. Messy Financials and Commingled Expenses: Running personal expenses through the business or using cash accounting instead of accrual accounting makes due diligence a nightmare. If buyers cannot trust your numbers, they will not trust your valuation.

What is the Cost of Going Direct vs. Using DealFlowAgent?

Many security founders are approached directly by PE-backed platforms or competitors offering a "quick, quiet sale without broker fees." This is almost always a mistake.

When you negotiate directly with a single buyer, they hold all the leverage. They will anchor the initial offer low, and then use the due diligence process to chip away at the price (the "due diligence discount"). Without a competing offer, you have no baseline to push back.

DealFlowAgent prevents this value depreciation by:

• Creating Competitive Tension: We bring multiple qualified, well-capitalized buyers to the table simultaneously.
• Protecting the Premium: Our process typically achieves a 27% higher valuation than the industry average.
• Negotiating the Structure: We fight for better deal terms, ensuring more cash upfront at closing, realistic working capital pegs, and minimized earn-out risk.

What is the Recent Market Activity in 2026?

The security systems M&A market remains highly liquid. Here are recent notable transactions demonstrating buyer appetite:

• ASSA ABLOY (Strategic): Acquired NSP Security in early 2026, continuing their aggressive expansion into electronic access control and integrated security solutions [5].
• Pye-Barker Fire & Safety (PE-backed): Continued their nationwide roll-up strategy, actively acquiring both fire safety and commercial security integration firms throughout Q1 2026.
• Alarm.com: Reported strong 2025 results and raised 2026 SaaS guidance, indicating massive market strength in the cloud/SaaS security model that acquirers are desperate to buy into.

Frequently Asked Questions (FAQ)

How much is my security systems business worth? Security businesses in the lower mid-market (£1M to £50M revenue) are typically valued based on earnings rather than revenue. Well-run companies generally sell for 3.5x to 6.5x Adjusted EBITDA, with significant premiums added for Recurring Monthly Revenue (RMR).

What multiple do security integration companies sell for? Most security firms sell for 3.5x to 6.5x EBITDA. However, platform-ready businesses with strong management teams, clean financials, and over 30% RMR can command premium multiples of 7.0x to 10.0x+ EBITDA.

How do buyers value security alarm monitoring contracts? Monitoring and managed services RMR is the most valuable asset in the industry. These contracts typically trade at 30x to 45x the monthly recurring revenue because attrition is low and margins are high.

Should I sell my security business now? The 2026 market is highly favorable for well-run security businesses due to strong private equity interest and the technological shift to cloud systems. If your revenue is growing, your financials are clean, and you have reduced your day-to-day operational involvement, it is an excellent time to explore a sale.

What mistakes should I avoid when selling my security company? Common pitfalls include failing to get a professional valuation, presenting inaccurate financials, having high RMR attrition rates, and negotiating directly with a single buyer without creating competitive tension. These mistakes can devalue a business by 20% to 50%.
