UK Electrical Business Market Report 2026

The UK electrical contracting sector is one of the largest and most fragmented segments of the construction and building services industry. For business owners considering their exit strategy, understanding the current market dynamics is essential to timing a sale correctly and achieving the best possible outcome.

This report draws on our proprietary analysis of Companies House data, public sector procurement records, and transaction intelligence gathered through our buyer network.

Market Size and Structure

The UK electrical contracting market is characterised by extreme fragmentation. The vast majority of the 205,522 active companies are small firms with fewer than 10 employees. This fragmentation creates a significant opportunity for acquirers seeking to build scale through consolidation, and it means there is a deep pool of potential acquisition targets for PE-backed platforms.

Our analysis identifies approximately 19,180 companies that meet the core criteria for being exit-ready: sole director or owner-operator, principal aged 55 or over, and a trading history of at least 10 years. Many of these business owners have no formal succession plan and have not explored their exit options.

Infrastructure Spending: The Demand Driver

Several structural spending programmes are creating sustained demand for electrical contracting services and, by extension, increasing the value of established electrical businesses.

EV Charging Network Expansion

The UK government's commitment to banning the sale of new petrol and diesel vehicles by 2035 is driving massive investment in EV charging infrastructure. The ZEV mandate requires that 80% of new car sales are electric by 2030. This creates a multi-year pipeline of electrical installation work for qualified contractors, from domestic charge point installations to commercial fleet charging depots and public rapid charging hubs.

Smart Building Retrofits

The push towards net zero is driving demand for smart building technology retrofits across commercial and public sector estates. Energy management systems, LED lighting upgrades, building management system (BMS) integration, and solar PV installations all require qualified electrical contractors. Local authorities and NHS trusts are among the largest commissioners of this work, typically procured through frameworks.

Data Centre and Grid Upgrades

The UK's data centre sector is growing rapidly, driven by cloud computing, AI, and digital transformation. Each new facility requires significant high-voltage and low-voltage electrical infrastructure. Meanwhile, the national grid itself is undergoing a generational upgrade programme to accommodate renewable energy sources and increased demand from electrification.

PE Consolidation Activity

Private equity firms have recognised the electrical contracting sector as an attractive consolidation opportunity. The combination of recurring revenue, regulatory demand drivers, and a fragmented market of acquisition targets makes it a textbook PE roll-up sector.

Notable recent PE activity in the electrical and building services space includes:

• Duke Street backing Suir Engineering, an M&E services platform expanding through acquisition
• Magnesium Capital investing in ABEC Group, building a national electrical and building services platform
• ECI Partners backing platforms in the electrical and mechanical engineering services sector

These PE-backed platforms are actively seeking regional electrical businesses with recurring testing revenue, strong registrations, and retained qualified teams. They typically acquire businesses with turnover between £1m and £10m, though some will consider smaller firms if the quality profile is right.

Valuation Trends

EBITDA multiples for electrical businesses have trended upward over the past three years, driven by increased buyer competition and the structural demand factors outlined above. Current indicative ranges:

• 3x to 5x EBITDA: Electrical businesses with a mix of installation and testing work, NICEIC or NAPIT registered, moderate recurring revenue
• 4.1x to 4.6x EBITDA: Specialist testing and inspection firms with strong recurring revenue, public sector frameworks, and retained qualified teams
• 5x to 7x EBITDA: Businesses with 50%+ testing revenue, established framework positions, NICEIC registration, ISO certification, and teams of 30+ qualified engineers

The BADR tax rate increase from 14% to 18% in April 2026 is creating additional urgency among owners who were already considering their exit. For a business valued at £1m, the difference between the old and new rate is £40,000 in additional Capital Gains Tax.

What This Means for Business Owners

The current market conditions are favourable for sellers. Buyer demand is strong, multiples are above historical averages, and the structural demand drivers (infrastructure spending, EV charging, smart buildings, grid upgrades) provide a compelling narrative for acquirers.

However, the market will not remain this strong indefinitely. Interest rate movements, PE fund deployment cycles, and political changes can all affect buyer appetite. Business owners who are considering their exit within the next two to three years should, at minimum, understand their current valuation and begin preparation.

The owners who achieve the best outcomes are those who start preparing 12 months before they go to market: cleaning up financials, formalising contract documentation, ensuring registrations are current, and reducing owner dependence.
