The LadderWhat the published ranges actually say
Mixed installation and testing businesses, registered with NICEIC or NAPIT and carrying a moderate share of recurring income, are generally valued at three to five times adjusted EBITDA. Specialist testing and inspection firms with strong recurring revenue, public sector framework positions and retained qualified teams sit higher, in the region of four and a half times. Businesses with more than half their revenue in testing, established framework positions, certification and teams of thirty or more qualified engineers reach five to seven times.
Those are market observations rather than promises, and the spread inside each band is wider than the gap between them. Two businesses described identically on that ladder can be a full turn apart on the strength of client concentration alone. The ladder is useful because it shows the direction of travel, which is consistently towards contracted, certificated, repeatable income and away from project turnover won by the owner.
It is also worth being clear about what the multiple applies to. Adjusted EBITDA, not turnover and not the profit in the filed accounts. For most owner-managed electrical contractors the adjustment for the owner's own remuneration and personal costs is the single largest number in the calculation, and getting it wrong in either direction misleads everybody including you.
The MechanismThe four things that move a business up the ladder
The first is the recurring share. Every rung on that ladder is really a statement about how much of next year's revenue is already scheduled. Fixed wire testing on a five-year cycle, periodic inspection and planned maintenance under written terms are the income a buyer can forecast, and forecastable income is what a multiple is applied to with any confidence.
The second is qualification and registration, which functions as a gate rather than an uplift. The third is framework and repeat client position, which is slow to win and immediately productive for a buyer, provided the call-off history shows it is genuinely producing work rather than sitting on a letterhead.
The fourth is the workforce, and it has become the scarcest of the four. The ECA reported in February 2026 that electrical apprenticeship starts had fallen by 5.5% despite rising demand, with fewer than one in five learners on government-funded classroom courses progressing into an apprenticeship or skilled employment across 2024 and 2025. Skills England estimate, reported by the ECA, that the country will need an additional twelve thousand electricians by 2030. A retained, graded, currently certificated team is the one thing on this list an acquirer cannot buy anywhere else.

The CautionWhy a published range is not a valuation
A range describes a market. Your business has one set of clients, one team, one owner and one set of records, and the price it achieves is decided by that particular combination meeting a particular buyer at a particular moment. Ranges are useful for calibration and misleading as expectations, which is why an adviser who quotes you a single multiple in the first conversation should be treated with some caution.
The things that drag a business below the range it looks like it belongs in are consistent and rarely surprising. One client carrying too much of the profit. Recurring work that turns out to be habit rather than contract. Records that cannot be produced. A team held together by the owner's personal relationships. Each is fixable, none is fixable quickly, and all four are known to the buyer by the end of the second meeting.
The honest way to use the ladder is backwards. Work out where the business sits today, identify the one or two features that separate that rung from the next, and decide whether closing that gap is worth eighteen months. Sometimes it plainly is. Sometimes the answer is that the business is what it is, the number is acceptable, and the better decision is to sell it well rather than to spend two years chasing a turn of EBITDA.

Working out which rung you are on takes your own figures rather than a published table. The valuation does that privately, and says what is holding you there.
