Ask two FM owners with identical turnover what their business is worth and the honest answer can be a long way apart. The difference almost never sits in the size of the top-line number. It sits in the shape of the contracts underneath it, and September, when new contracts go live and annual renewals fall due, is the clearest month of the year to see it.
A Snapshot Versus an Annuity
A business living on rolling purchase orders and twelve-month arrangements is selling a snapshot. The income is genuine, but a buyer cannot be confident it will still be there once they own the business, so they price in that uncertainty. The offer reflects the risk, not the effort behind the revenue.
A business with three-year terms and a documented renewal record is selling something else entirely: revenue an acquirer can model years ahead. That is the distinction that decides most FM valuations. Margin tells a buyer what you do; contract length tells them how long they can rely on it, and it is the second question that the multiple is really built on.
This is the same principle that sits behind the biggest deals in the sector, where funds pay up for recurring, compliance-led revenue precisely because it recurs. I set out the 2026 evidence for that in a separate piece on why recurring revenue is the whole game. The logic scales all the way down: whatever the size of the business, durable contracts are what a buyer is paying for.
Renewal History Is the Part Owners Undervalue
Renewal history is the evidence most owners carry in their heads rather than their files, and a fact a buyer cannot see is a fact they will not pay for. A book that retains ninety per cent or more of its contracts year after year reads as an annuity, and buyers price annuities generously because the arithmetic behind them is predictable.
September makes that record easy to build, because every contract that renews this month is a fresh data point. The practical work is a simple, current record of each contract: its start date, its term, its renewal or extension history, and an honest note on whether the income genuinely recurs or is a run of one-off orders dressed up as a relationship. Diversification belongs in the same picture, because a book spread across commercial offices, healthcare, education, logistics and retail reads as more resilient than one concentrated in a single client sector.
What It Is Worth in the Range
Established FM businesses with multi-year contracts are valued on a multiple of EBITDA, with the multiple rising for larger operations with blue-chip rosters and long terms, and often cross-checked against annual contract revenue where contracts dominate income. Where a business lands is driven far more by contract quality than by anything said across the negotiating table.
Contract length and renewal history are only the first part of what a buyer weighs, alongside the workforce, margin quality and mobilisation record I set out in the September briefing on the anatomy of a valuable FM book. The task for contract season is not glamorous, but it is valuable: capture the length and renewal history of your book while the evidence is being created around you. It is the single most persuasive part of the case a buyer will read.
