ICEL Power Systems acquired by Bouygues

Acquirers in this sector pay primarily for installed base economics: the recurring service and maintenance revenue attached to UPS systems and standby generators already in the field. They value a balanced mix of new-installation revenue and contracted service income, low customer concentration, and a long-tenured engineering team. A documented service contract book with clear renewal rates is often more important to valuation than headline revenue growth. UK-based buyers and European industrial groups with UK service operations are typically the most active acquirers, and the highest multiples go to businesses that can demonstrate both technical depth and service-revenue durability.

UK mid-market M&A buyers — typically larger electrical contractors, facilities management groups and European industrial platforms — assess critical power businesses against a defined commercial framework. They look at installed base size and geographic density, recurring maintenance revenue as a percentage of total turnover, customer sector mix (data centres and healthcare command a premium), engineering headcount and tenure, and exposure to single-customer concentration risk. EBITDA quality is scrutinised hard: one-off project margins are stripped out and adjusted EBITDA is built up from underlying service-contract economics. A clear bridge from reported operating profit to maintainable EBITDA is essential for defending valuation through heads of terms and due diligence.

Large European industrial groups — Bouygues, Vinci, Eiffage, Engie and others — have consistently used UK acquisitions to scale their facilities management and electrical services divisions outside the eurozone. The UK market is attractive because of its scale, the long-term nature of public-sector facilities contracts, and the fragmentation of the specialist electrical installation segment. UK-based independent operators with critical power capability, established customer relationships and trained engineering teams are difficult to build organically and quick to integrate into an existing service platform. For UK founders, that creates a recurring buyer-type with genuine appetite, long ownership horizons, and a track record of retaining acquired brands and teams.

The installed base — every generator, UPS and switchgear installation under an active service or maintenance contract — is the primary asset acquirers underwrite. They assess contract renewal rates over the trailing three to five years, average contract length, price per service visit, and the strategic importance of the protected load to the customer. A data centre or hospital UPS contract carries a materially higher renewal probability than a commercial property generator contract. Acquirers also look at the spare parts and consumables revenue tied to the installed base, which often delivers higher gross margins than the core service contract itself. A well-documented installed base register, with customer, asset, contract terms and service history, is one of the highest-impact pre-sale preparation steps a founder can take.

The most valuable preparation work in this sector happens 18 to 36 months before going to market. Three actions matter most: documenting the installed base and service contract economics so a buyer can underwrite recurring revenue with confidence; reducing the founder's direct customer-relationship dependency by transferring key accounts to named team members; and tightening the financial reporting so that maintainable EBITDA can be defended without reliance on management add-backs. A multi-year track record of clean audited accounts, a stable senior engineering team, and a demonstrable pipeline of new-installation work alongside the service book all materially improve valuation. CapEQ's Three-Year Exit Roadmap is built around exactly this preparation cycle.

Key-man risk is the term acquirers use when too much of a business's customer pipeline, technical authority or commercial decision-making sits with one or two individuals — usually the founder. In the UK electrical contracting and critical power sector, where customer relationships are often built over decades by a founder personally calling on procurement and facilities teams, this risk is structural rather than operational. It suppresses valuation because the buyer has to discount for the probability of customer loss after the founder exits. The mitigation is a deliberate two-year transition: customer relationships are formally transferred to senior account managers, tender authority is delegated, and the founder steps back from frontline customer contact in a documented, observable way. Buyers reward businesses where the leadership team rather than the founder owns the customer base.

Multi-shareholder electrical and contracting businesses — typically with two or three working founders each holding a meaningful equity stake — face a specific exit challenge: each shareholder usually has a different view on price, timing, post-completion involvement, and the cultural fit of the buyer. Resolving these differences before going to market is essential. The practical mechanism is a shareholder pre-sale workshop, ideally facilitated by the M&A advisor, that surfaces each shareholder's individual position on minimum acceptable price, earliest and latest acceptable completion date, willingness to stay on post-completion, and red-line buyer characteristics. Documented alignment up front prevents the most damaging outcome in any process: a shareholder dispute surfacing at or after heads of terms, when buyer trust and competitive tension are both fragile.

CapEQ is Europe's first Certified B Corporation M&A boutique, certified in 2021. For founders of UK electrical contracting and critical power businesses — sectors where engineering teams have often spent decades together and where customer relationships outlast any individual contract — that certification matters in three practical ways. First, it independently verifies that the advisor prioritises the client outcome over deal income, including the willingness to recommend not selling when the timing or terms are wrong. Second, it signals a structured commitment to staff and customer-protection terms inside the deal itself. Third, it provides external validation of advisor independence — CapEQ holds no audit, tax or other service-line relationships that could create a conflict of interest in advising on a sale. For founders who care about the long-term home for the business and team, that combination is difficult to replicate.
