About 151 UK facilities-management companies publish a full profit-and-loss, booking £11.35bn of combined turnover between them — cleaning, catering, security, maintenance and reception for other people’s buildings. The trade’s defining number is small: the median operator keeps about 4p of every pound of contract revenue. OCS Group UK employs 23,880 people to turn £840.8M into £30.9M; Bidvest Noonan runs 14,797 people on £509.7M and lost money doing it. And yet the same map contains companies booking 26–36% margins on the same kind of work. Look closely and none of them is competing for it: they are PFI concession vehicles collecting availability payments on decades-old government deals, and NHS trusts’ own wholly-owned FM companies serving a single captive customer. In facilities management, a fat margin is almost always a sign that the contract never went to tender. Figures are approximate — verify against a company’s own accounts before relying on any single number.
Before you compare any two rows
Three things distort this map, and they matter more here than in most industries:
- The giants are fragments. The biggest FM groups report through many companies. Mitie appears twice in the top ten alone (its core FM company and its defence business); Equans appears through Equans Services and Equans Buildings; and several of the largest FM operations in Britain — ISS, Sodexo, Serco’s and Compass’s FM arms — report through companies we classify with caterers, security firms and support-services groups elsewhere. Treat each row as an entity, not a whole business.
- Labour resale and technical maintenance are different trades. The soft-FM giants — OCS (
£35k of revenue per employee), Bidvest Noonan (£34k), Churchill (£28k) — are essentially organised labour at scale: thousands of cleaners and guards whose wages pass through the P&L. The hard-FM and maintenance names — Mears (£280k per head), Kier Facilities Services (~£239k) — run materials- and subcontract-heavy models with a fraction of the headcount. Their margins are not comparable, and this map contains both. - TUPE makes growth mechanical. When an FM contract changes hands, the incumbent’s workforce usually transfers with it. So revenue growth arrives with staff attached — a +40% turnover / +40% headcount pair is how a contract win looks, not evidence of a hiring spree. The growth table below should be read with that in mind.
The giants
| Company | What it is | Turnover | PBT | Headcount | TO YoY | Staff YoY |
|---|---|---|---|---|---|---|
| Mitie FM | core FM arm of the listed Mitie group | £1.10bn | £65.9M | 9,457 | +7% | −5% |
| Mears | housing maintenance (listed group’s trading arm) | £1.03bn | £67.9M | 3,692 | +4% | +14% |
| OCS Group UK | soft FM — merged mega-group under PE ownership | £840.8M | £30.9M | 23,880 | +47% | +43% |
| Equans Services | UK arm of the French energy-and-services group | £747.7M | £49.2M | 6,713 | −6% | −9% |
| Bidvest Noonan (UK) | cleaning & security soft FM | £509.7M | −£494k* | 14,797 | +2% | −11% |
| CBRE GWS | CBRE’s UK workplace-solutions entity | £439.0M | −£17.7M | 1,950 | +8% | +4% |
| Churchill Contract Services | family-owned cleaning-led soft FM | £406.4M | £21.1M | 14,363 | +6% | −3% |
| Amey Community | Amey’s PFI soft-services arm | £370.1M | £18.1M | — | −1% | — |
| Mitie (Defence) | Mitie’s defence-estate contracts | £257.4M | £43.4M** | 1,446 | +12% | +6% |
| Kier Facilities Services | hard FM arm of the listed contractor | £234.1M | £32.1M | 979 | −1% | +5% |
| City Facilities Management | Glasgow-based retail-FM specialist | £227.0M | −£10.4M | 1,134 | +48% | +22% |
| ABM Facility Services UK | UK arm of the US-listed ABM | £226.7M | £13.6M | 5,494 | +12% | +3% |
*Bidvest Noonan’s pre-tax loss is £8.5M of intercompany loan interest landing on the P&L; at the operating line it made £9.0M, a 1.8% margin, up from 1.4%. **Mitie (Defence)‘s £43.4M PBT includes £10.5M of dividends from subsidiaries and £3.7M of net group interest — its trading (operating) margin is 11.3%.
…and 139 more below them.
The table splits on the labour line drawn above. The soft-FM giants earn low single digits or nothing: OCS at 3.7%, Churchill at 5.2%, Bidvest Noonan at breakeven-minus — though its −£494k pre-tax is £8.5M of intercompany loan interest arriving on the P&L, not the contracts failing: at the operating line it made £9.0M, a 1.8% margin that improved on the prior year even as 11% of the workforce went. The asset-and-maintenance names earn more per pound with far fewer people: Kier’s FM arm makes 13.7% with 979 staff, Mears converts £1.03bn of housing repairs into £67.9M, and the standout looks like Mitie (Defence) at 16.9% — but the accounts deserve the look inside: £10.5M of that £43.4M PBT is dividends from subsidiaries and £3.7M is net group interest, leaving a trading margin of 11.3% against 4.8% at the group’s core FM company on the same operating basis. Defence-estate work still pays roughly double office cleaning — just not triple. The two losses both have stories: CBRE GWS is one entity within a much larger CBRE UK structure, so its £17.7M loss says as much about where the group books cost as how the contracts trade; City Facilities Management grew 48% in a year and lost £10.4M doing it — revenue bought, not yet earned.
The shape of the market
The mid-market is the healthy part of this trade. The £5–25M and £25–100M bands hold 85 of the 151 companies at 82–85% profitable — regional contractors with dense local books. The graveyard is at the very bottom (under £1M, only 45% profitable — too small to carry the overhead an FM contract demands) and the pressure returns at the top: the £100M–1bn band dips to 76% profitable, because that’s where the national soft-FM contracts with procurement-squeezed pricing live.
| Turnover band | n | Profitable % |
|---|---|---|
| < £1M | 20 | 45% |
| £1–5M | 15 | 87% |
| £5–25M | 44 | 82% |
| £25–100M | 41 | 85% |
| £100M–1bn | 29 | 76% |
| £1bn+ | 2 | 100% |
The “best-run” table is full of companies that don’t compete
Rank the profitable £5–100M operators by margin and something odd happens: many of the best names aren’t in the market at all.
Start with the two fattest margins. RMPA Services turns £52.7M into £19.0M — 36.1% — with 11 employees; Meridian Hospital Company turns £37.1M into £9.5M — 25.7% — with none at all. Neither is an FM contractor in any competitive sense. Both are PFI project companies: special-purpose vehicles that financed a public building decades ago (an Army garrison redevelopment in RMPA’s case, a south-London hospital in Meridian’s) and now collect index-linked availability payments for the rest of the concession, subcontracting the actual mopping and maintenance. Even that annuity is lumpier than it looks — Meridian’s turnover fell a quarter last year as variation work rolled off. Their “margin” is the return on a financing structure, not operating skill — and Meridian appears twice in the raw ranking (the concession company and its holding company report the same £37.1M), so the map double-counts it.
Then comes the quieter surprise: the NHS is one of the best-run FM operators in Britain — because it hired itself. Four of the top twenty are wholly-owned subsidiaries of NHS trusts: QE Facilities (Gateshead’s trust, £79.0M at 8.5%), NTW Solutions (the Cumbria, Northumberland, Tyne and Wear mental-health trust, £69.3M at 4.3%), Simply Serve (Somerset, £43.1M at 7.2%) and RFL Property Services (the Royal Free’s, £31.2M at 4.3%, growing). Between them that’s roughly £220M of estates, cleaning and logistics work that trusts decided to run through their own companies — with the VAT and employment-flexibility advantages that structure brought — rather than buy from anyone in the tables above. They post market-beating margins with precisely one customer each.
Strip out the concession vehicles, the trust subsidiaries, the group arms (Galliford Try FM, JLL Resources, Dalkia’s northern entity) and one construction firm the raw ranking sweeps in, and the genuinely independent, genuinely competing operators look like this:
| Company | What it is | Turnover | PBT | Margin | Headcount |
|---|---|---|---|---|---|
| HR Facilities | technical-FM profile (~£197k revenue/head) | £78.4M | £7.4M | 9.4% | 398 |
| RMPA Services | PFI concession — for contrast | £52.7M | £19.0M | 36.1% | 11 |
| Portico | corporate front-of-house & reception | £46.3M | £2.9M | 6.3% | 1,015 |
| Antac Support Services | independent soft FM | £42.3M | £4.0M | 9.4% | 455 |
| Combined Technical Solutions | technical / M&E maintenance | £39.5M | £2.2M | 5.6% | 249 |
| Outco | outdoor estates — gritting, grounds, surfacing | £39.2M | £6.9M | 17.7% | 182 |
| Sasse | UK arm of a German family FM group | £37.2M | £1.4M | 3.8% | 1,199 |
| Rydon Maintenance | housing repairs & maintenance | £35.0M | £4.1M | 11.8% | — |
| Pendergate | cleaning group (~£14k revenue/head — part-time workforce) | £32.5M | £2.4M | 7.2% | 2,325 |
| 24-7 FM | subcontract-led FM (43 staff on £27M) | £26.9M | £2.1M | 7.9% | 43 |
The pattern among the real competitors is the same one we found in road freight: specialism pays and generalism doesn’t. The best genuine margin in the niche belongs to Outco at 17.7% — compliance-driven outdoor work (winter gritting, surfacing) where the risk of an icy car park, not a procurement spreadsheet, sets the price — a margin that doubled year-on-year as restructuring one-offs dropped out, though its underlying EBITDA margin has run about 21% for two years. Maintenance-led models (Rydon, 11.8%) and well-run regional soft FM (Antac and HR Facilities at 9.4%) sit in the high single digits. Broad-line contract cleaning at scale earns 4–7% on a good day.
Growth, read with care
| Company | Turnover | PBT | Margin | TO YoY | Staff YoY |
|---|---|---|---|---|---|
| Sasse | £37.2M | £1.4M | 3.8% | +81% | +96% |
| Totalis Solutions | £20.0M | £1.6M | 7.8% | +53% | +26% |
| City Facilities Management | £227.0M | −£10.4M | −4.6% | +48% | +22% |
| OCS Group UK | £840.8M | £30.9M | 3.7% | +47% | +43% |
| Chequers Contract Services | £21.7M | £721k | 3.3% | +42% | +43% |
| Equans Buildings | £140.1M | £17.4M | 12.4% | +35% | +1% |
| Kanso Facilities Management | £19.5M | £1.2M | 6.0% | +33% | +28% |
| Combined Technical Solutions | £39.5M | £2.2M | 5.6% | +31% | +25% |
The biggest number is the least organic. OCS Group UK’s +47% is mostly consolidation arriving on the books — group companies hived up into one entity in the wake of the OCS–Atalian Servest merger, plus four bolt-on acquisitions — with some genuine wins (roughly £73M annualised) underneath. City Facilities Management is the cautionary opposite: +48% revenue, +22% staff, and a £10.4M loss — growth won on price in retail FM, where the customer holds all the negotiating power. Equans Buildings’ +35% at a 12.4% margin looks superb, but it is one entity inside a group that also shrank its services arm 6% the same year — work moving between group companies can masquerade as growth.
The genuine article is further down: Sasse (+81% revenue, +96% staff — contracts won with their workforces transferring in, still profitable at 3.8%), Belfast’s Totalis Solutions (+53% at a 7.8% margin), Kanso and Combined Technical Solutions both compounding around +30% while holding mid-single-digit margins. In a 4% trade, growing at 30% without dropping to zero margin is the achievement.
Market structure
| Share of combined turnover | |
|---|---|
| Top 5 companies | 37.3% |
| Top 10 companies | 52.3% |
| Top 20 companies | 68.0% |
| Top 50 companies | 87.9% |
| Top 100 companies | 98.5% |
On paper the top ten hold half the map. In practice the concentration is understated and overstated at once: understated because the majors report through multiple entities (two Mitie companies and two Equans companies appear in these tables) and several of Britain’s biggest FM operations sit in companies classified with caterers and security groups outside this map; overstated because each row is only a slice of a group. Read the curve as the shape of the visible trade, not a competition ruling.
Ownership and vintage: an industry minted by policy
FM’s company vintages track government policy more neatly than almost any industry we’ve mapped. The 1990s cohort (32 companies) is the child of compulsory competitive tendering, which forced councils and hospitals to buy cleaning and maintenance from the market. The 2000s — the biggest cohort at 52 — is the outsourcing and PFI boom. And inside the 2016–20 cohort (18) sits the counter-revolution: the NHS subsidiary wave, when trusts incorporated their own FM companies (NTW Solutions in 2016, Simply Serve in 2017, RFL Property Services in 2018) and began taking the work back in-house. Each generation of Whitehall procurement doctrine minted its own generation of companies.
| Incorporation cohort | Companies |
|---|---|
| Pre-1990 | 14 |
| 1990s | 32 |
| 2000s | 52 |
| 2010–15 | 28 |
| 2016–20 | 18 |
| 2021+ | 7 |
Of the 151 companies, 87 are corporate-owned against 52 owned by individuals, and about 16% carry a Holdings/Group/Bidco-style name — the structural fingerprint of a buyout done or planned. In a trade this labour-heavy, private equity’s interest is the contracts’ stickiness, not the margins: the same logic that drives the roll-ups in our temp-staffing map, a business where the workforce is the asset and TUPE moves it wholesale.
What the map shows
- This is a 4p-in-the-pound trade. The median operator keeps about 4% of contract revenue; OCS needs 23,880 people to make £30.9M, and Bidvest Noonan ran £509.7M of work at a loss.
- The fat margins never went to tender. The 26–36% “margins” belong to PFI concession vehicles (RMPA Services, Meridian Hospital Company) collecting availability payments on decades-old deals — financing returns wearing an FM costume.
- The NHS quietly became one of the best-run FM operators — four trust-owned subsidiaries (~£220M combined) post market-beating margins serving exactly one customer each, the 2016–20 in-housing wave made corporate.
- Labour resale and technical maintenance are different businesses. ~£30k revenue per head and 3–5% margins for the cleaning-and-security giants; £200k+ per head and 12–14% trading margins for maintenance and defence-estate work. Never compare the two.
- Growth arrives with a workforce attached. TUPE means turnover and headcount move together mechanically; the rare signal is growing 30%+ while staying profitable (Sasse, Totalis, Kanso, CTS) — not the consolidation-inflated +47% at the top.
- Specialism beats scale on margin. The best genuine independent margin is Outco’s 17.7% in compliance-driven outdoor estates; broad-line soft FM at national scale earns less than a corner of a car park it grits.
Methodology and caveats
This covers only the 151 UK facilities-management companies that publish a full profit-and-loss — the long tail of small contractors files abridged accounts with no figures, and several of the biggest FM operations in Britain report through companies classified with caterers, security and support-services groups, which appear in other maps. Group structures report at several levels: Mitie and Equans each appear through two entities, and Meridian Hospital Company’s concession and holding companies report the same £37.1M, so the £11.35bn combined turnover modestly overstates the distinct-group total. PFI concession vehicles’ margins are financing economics, not operating performance, and are never comparable with a contractor’s; entity-level profits and losses (CBRE GWS, Equans Buildings) can reflect where a group books cost or moves work rather than how contracts trade. Business descriptions are directional. Figures are approximate — verify against a company’s own accounts before relying on any single number. This is analysis, not financial advice.
