Strip away the sector jargon and every strong FM valuation rests on one thing: the buyer's confidence that the revenue will still be there in three years' time. That is why contract length and renewal history are the real currency of an FM sale, far more than headline turnover. In 2026, the evidence for that principle is unusually clear.
Margin Tells Them What, Contract Length Tells Them How Long
Margin tells a buyer what you do; contract length tells them how long they can rely on it. A business living on rolling purchase orders and 12-month arrangements is selling a snapshot. A business with three-year contracts and a 90 per cent-plus renewal record is selling an annuity, and buyers price annuities at a premium because they can model them with confidence.
This is not a new idea, but 2026 gave it a live illustration at institutional scale. When Investcorp took a majority stake in Smart Managed Solutions in June, a business with over £100 million revenue and more than 30 per cent annual organic growth on recurring M&E maintenance, it was the same principle written large: pay up for revenue that recurs and grows without constant re-winning.
The Wage Floor Is a Margin-Quality Test
The other half of the 2026 evidence runs through the cost base. The National Living Wage reached £12.71 an hour on 1 April 2026, a 4.1 per cent rise. Every increase compresses margin on contracts priced as an input cost rather than as an output the client buys.
This is why buyers stress-test how your contracts are priced. A soft FM book built on fixed, input-priced labour contracts sees a wage rise eat straight into profit. A book of output-based contracts with pass-through mechanisms, where the client absorbs statutory cost increases, holds its margin and therefore its value. The wage floor has quietly become a way for buyers to sort durable contract books from fragile ones.
Diversification Is the Second Half of the Story
Recurring revenue is only as safe as it is spread. A book concentrated in one client industry is discounted almost as sharply as one concentrated in a single client, because the buyer is pricing the risk that a sector-wide shock takes a slice of the revenue at once.
A contract portfolio spread across commercial offices, healthcare, education, logistics and retail reads as more resilient, and resilience is what the multiple rewards. Established FM businesses with multi-year contracts continue to transact in the 4x to 7x EBITDA range, rising to 6x to 10x for larger operations with blue-chip rosters and long terms. Where a business sits inside that range is driven by revenue quality far more than by anything said in the negotiation.
There is a workforce angle to recurring revenue too. The IWFM Market Outlook Report 2026 found 51 per cent of organisations reporting a shortage of FM staff, and 68 per cent of leaders saying it is challenging to hire and retain skilled people. A book of recurring contracts is only as reliable as the team that delivers it, so a business that self-delivers with a stable, retained workforce protects the very revenue a buyer is paying for. That combination, recurring contracts plus the people to service them, is what turns a paper renewal rate into durable income.
What to Do About It
None of this requires a transformation. It requires knowing which of your contracts are genuinely recurring, documenting the renewal history that proves it, and being able to show a buyer that the income is diversified, output-priced and self-delivered. That evidence is the difference between the top and bottom of the range. Recurring revenue is one of four forces I set out in my August market briefing for FM owners, alongside the buyer map and the year's biggest deals.
