How to Sell a Cleaning Business in the UK

If you want to sell a cleaning business in the UK, you're operating in one of the few small-business sectors where demand from buyers reliably outstrips good supply.

The British Cleaning Council's 2026 research report puts the cleaning, hygiene and waste sector at nearly £72bn, up from £67.7bn, spread across 78,915 businesses employing 1.51 million people.

Read that structure rather than the headline. Nearly 79,000 businesses in a £72bn market means the average operator is tiny, and a fragmented market is a consolidating market. Larger regional cleaning groups grow by buying contract books, not by cold-calling offices one at a time. Private equity has been building facilities-management platforms for a decade and those platforms need bolt-ons.

So the buyer pool for a decent cleaning company is genuinely deep: trade buyers wanting your contracts, first-time owners wanting a business with recurring income, and management teams wanting to buy you out.

Here's the thing most owners get wrong, though. They assume the buyer is paying for turnover. Buyers are paying for contracted revenue that survives your departure, and those are two very different things. A £900,000 cleaning company where the owner personally holds every client relationship is worth substantially less than a £600,000 one with signed contracts, a stable supervisor layer and an owner who hasn't cleaned anything in three years.

This guide covers what cleaning companies actually sell for, why contract quality decides the multiple, how TUPE shapes the deal, and what to fix in the six months before you list. If you want the other side of the table, our guide to buying a cleaning business sets out exactly what buyers are checking.

Cleaning companies are valued on earnings, and which earnings measure applies depends on your size.

Owner-operated, under about £500,000 turnover. Valued on seller's discretionary earnings, typically 1.5x to 3x SDE. SDE is your net profit plus your own salary, pension and any personal costs running through the business.

£500,000 to £3m turnover with a management layer. Valued on EBITDA, typically 3x to 5x. The step up happens because the business runs without you.

Above £3m, or with strong contracted commercial work. 4x to 6x EBITDA, and specialist contract books in sectors like healthcare or food manufacturing can go higher because those clients are hard to win and slow to switch.

Where you land inside those ranges is mostly about contract quality:

Factor	Pushes the multiple up	Pushes it down
Contracts	Signed, 12 months+, auto-renewing	Rolling monthly, verbal, "we've always done it"
Client mix	No client over 15% of revenue	One client at 40%+
Work type	Commercial, contracted, daytime	Domestic, ad hoc, cash
Staff	Contracted, retained, DBS-checked	High churn, agency-dependent
Owner role	Strategic, replaceable	Sells, prices, and covers shifts

Domestic cleaning is worth flagging separately. Domestic rounds are easier to build and harder to sell: customers cancel freely, there's rarely a contract, and the earnings often depend on the owner's local reputation. Expect the lower end, 1x to 2x SDE, unless you've genuinely systemised it.

The generic mechanics of valuation are covered in our business valuation guide, and our normalised EBITDA guide explains how to present the adjusted figure buyers will actually underwrite.

This is the section to read twice if you read nothing else.

Look at where turnover sits on that list. Buyers care about it far less than owners do, because turnover tells them how big you are, not how much of you they'll still have in eighteen months.

What buyers actually examine:

The contract schedule. Every client, start date, term, notice period, renewal mechanism, monthly value, and whether it's signed. Owners routinely discover during due diligence that a third of their "contracts" are emails from 2019. Fix that before you list, not during.

Notice periods. A book of contracts on 30 days' notice is barely better than no contracts. Twelve months with a three-month notice period is a real asset. If your agreements are loose, spend the six months before sale getting clients onto proper terms. Most will sign. It costs you nothing and it directly raises what a buyer will pay.

Concentration. If one client is 40% of revenue, the buyer is effectively pricing the risk that they leave. Expect a discount, a large deferred element, or both. Under 15% per client is comfortable.

Churn history. Show three years of client wins and losses. A book that loses 8% a year and wins 15% is healthy and demonstrable. A book that has never lost anyone is either exceptional or badly documented, and buyers will assume the second.

Pricing headroom. Contracts that haven't been repriced since 2022 are a liability, because your wage bill has moved and the buyer inherits a margin problem. Reprice before you sell. Yes, you might lose one or two. The ones that stay are worth more.

Honestly, this is the highest-return work available to a cleaning company owner. Getting contracts signed and repriced can add a full turn to the multiple, and it takes months rather than capital.

Cleaning is a people business, and the legal position on those people shapes every deal.

TUPE applies, and it cuts both ways. In a share sale the employer doesn't change, so contracts continue automatically. In an asset or contract sale, the Transfer of Undertakings (Protection of Employment) Regulations transfer your staff to the buyer on their existing terms, with continuity of service intact. Buyers know this, and they will price the liabilities they're inheriting.

What they'll want to see:

1. Full employee list with start dates, hours, rates, holiday entitlement and accrued holiday.
2. Right to work documentation for every member of staff. In a sector with a large migrant workforce, this is the single most common problem found in due diligence.
3. Any live disciplinary, grievance or tribunal matters.
4. Whether you're paying at least the National Living Wage for every hour actually worked, including travel between sites where that counts as working time.
5. Pension auto-enrolment compliance.
6. DBS checks where clients require them, particularly in schools, care and healthcare work.

Where sales fall apart. Two patterns recur. The first is unpaid holiday accrual that nobody has quantified, which becomes a completion-account adjustment and a bad-tempered negotiation. The second is a workforce paid partly in cash, which no serious buyer will touch, because they cannot inherit that liability or finance against the earnings it produces.

If any part of your payroll doesn't survive daylight, deal with it before you go to market. You'll take a hit on reported profit and you'll get a real business you can actually sell. Our guide on what liabilities transfer in a business sale explains how buyers think about this.

One practical suggestion that works well. Supervisors matter more than cleaners. A buyer can replace a cleaner in a week; a good area supervisor who knows twenty sites and forty staff is genuinely hard to replace. Identify yours, and consider a retention arrangement that keeps them in place through the transition. Buyers will pay for that certainty.

Knowing your buyer changes how you package the sale, and most owners never think about it until offers arrive.

Regional trade buyers. Established cleaning or facilities-management companies covering your area. They want your contracts and your supervisors, and they can strip out your back office, so the same earnings are worth more to them than to anyone else. They pay the best prices and negotiate the hardest, because they know exactly what they're looking at. They'll want to know your client names before committing, which is a confidentiality problem you have to manage carefully.

Consolidators and private-equity-backed platforms. Building national coverage by buying regional operators. They pay well above trade multiples for businesses above roughly £1m of EBITDA, less so below that. They bring lawyers, a long due diligence process, and a lot of deferred consideration tied to earn-outs. If you want a clean exit with cash on completion, read the structure carefully before you get excited about the headline number.

First-time owner-operators. Buying a job with a business attached, usually under £400,000. They're financing with savings plus a loan, so they need the accounts to be lender-ready and the earnings to support both a wage and the debt. Slower, more emotional process, and they drop out more often. They also don't strip your overheads, so they can't justify a trade buyer's price.

Your own management team. An MBO is worth considering if you have a strong operations manager. Price is usually lower and heavily deferred out of future profits, but the transition is smooth, the staff stay, and confidentiality is a non-issue because they already know.

Adjacent service businesses. Window cleaning, waste, pest control, landscaping and security firms sometimes buy cleaning companies to cross-sell into an existing client base. Underrated, and worth a direct approach if any operate in your area.

The practical point: your business is worth different amounts to different buyers, and the spread between them is wide. Running a process that reaches at least two categories is usually worth more than any negotiating tactic. An owner who only ever speaks to one interested party has no idea what they left on the table.

Almost every pound of extra value in a cleaning company sale is created before the business goes to market. Here's the sequence I'd follow.

The preparation sequence that pays

Months 1 to 2: clean up the numbers. Get three years of accounts into shape and prepare a normalised EBITDA schedule showing your own salary, pension, vehicle, phone and any genuinely personal costs added back. Separate one-off items from recurring ones. If your bookkeeping is a shoebox, this alone takes eight weeks and it's the foundation of everything else.

Months 2 to 3: paper the contracts. Every client on a written agreement with a defined term and notice period. Reprice anything that's fallen behind. Chase the ones that drift.

Months 3 to 4: remove yourself. If you price the jobs, do the rotas, handle the complaints and cover the sickness, the buyer is buying a job. Promote or hire an operations manager and genuinely hand over. This is the hardest step and the one that moves the multiple most, because it's the difference between an SDE valuation and an EBITDA valuation.

Month 5: fix the obvious diligence problems. Right to work files. Holiday accrual reconciliation. Insurance in place, including employer's liability at the right level. Equipment owned outright or with the finance clearly documented. Any COSHH and health-and-safety paperwork a commercial client would expect.

Month 6: build the information pack. Contract schedule, client list with revenue and tenure, staff schedule, three years of accounts plus current management accounts, equipment list, insurance certificates, and a short honest narrative about how the business runs and where it could grow.

That pack does two jobs. It shortens the sale, because buyers can answer their own questions. And it signals competence, which is worth real money: a buyer who trusts the numbers negotiates less aggressively than one who suspects surprises.

Our key steps to selling a business covers the wider process, and common seller mistakes is worth reading before you start.

The headline price isn't the number that matters. What lands in your account is.

Business Asset Disposal Relief has changed, and not in your favour. GOV.UK sets the rate at 10% for disposals on or before 5 April 2025, 14% between 6 April 2025 and 5 April 2026, and 18% from 6 April 2026. The lifetime limit is £1m of qualifying gains.

So on a £1m qualifying gain, BADR at 18% costs £180,000, against £100,000 under the old 10% rate. That's £80,000 of the same sale now going to HMRC.

To qualify you generally need to have held at least 5% of the ordinary share capital and voting rights, been an officer or employee, and met those conditions for at least two years before the disposal. Get that checked early, because two years is not something you can fix in the month before completion.

Share sale or asset sale? Sellers usually prefer a share sale: one disposal, potential BADR, and the company's history goes with it. Buyers often prefer an asset sale, because they choose what they take and leave the liabilities behind. In cleaning specifically, an asset sale still triggers TUPE, so the staff transfer regardless, which removes one of the buyer's usual arguments.

The gap between the two structures is often worth more than the last round of price negotiation, so take advice before you agree heads of terms rather than after. Our Business Asset Disposal Relief guide goes through the qualifying conditions in detail.

Fair warning: I'm setting out the framework, not giving you tax advice. The rules around associated disposals, holding companies and trading status have teeth, and a decent accountant will earn their fee several times over on a deal this size.

This worked example is an illustrative composite built from typical market figures, not a record of a specific transaction. Use it as a method, and run your own numbers on your own business.

A commercial cleaning company in the Midlands. Turnover £740,000, 34 staff, 41 clients, owner working full time in the business.

The owner's expectation. "We turn over three quarters of a million. Similar businesses go for around turnover, so £700,000?"

What the numbers showed:

Line	Annual	Notes
Turnover	£740,000	41 clients
Direct labour	£487,000	34 staff including supervisors
Materials, equipment, vehicles	£68,000
Insurance, admin, premises, software	£54,000
Owner's salary and benefits	£62,000	Added back for SDE
Reported profit	£69,000
SDE	£131,000	Profit plus owner's package

Turnover-based pricing was never realistic. On SDE the honest starting range was 2x to 3x, so £260,000 to £390,000.

Then the contract review, which is where the value moved.

Of 41 clients, 12 were on signed contracts with 12-month terms. The other 29 were rolling monthly arrangements, several undocumented. The largest client was 22% of revenue on 30 days' notice. And nothing had been repriced since 2023, while the wage bill had risen with the National Living Wage.

At that point a buyer prices risk, not earnings. The offers reflected it: around 2x SDE with half deferred over two years against client retention.

What twelve months of preparation did. The owner postponed, then: moved 31 of the 41 clients onto signed 12-month contracts with three-month notice; repriced the book by an average 6%, losing two small clients; promoted a supervisor to operations manager on £41,000; and stepped back to two days a week.

The rebuilt position: turnover £762,000, EBITDA after a genuine manager's salary £98,000, largest client down to 17%, and 76% of revenue contracted.

That business sold on EBITDA at 4x, so £392,000, with only 20% deferred. Against the £260,000 to £390,000 SDE range twelve months earlier, and against a much worse deal structure.

The extra value came almost entirely from paperwork and one hire. That's the honest lesson of this sector.

Three routes, and the right one depends on your size.

A specialist broker makes sense above roughly £1m of turnover, or where the contract book is complex enough to need packaging. Expect 5% to 10% commission plus, often, an upfront fee. A good one brings trade buyers you'd never reach and manages a competitive process. A bad one lists you on the same portals you could have used yourself and waits.

A marketplace listing works well for owner-managed businesses in the £150,000 to £750,000 range, which is most of this sector. You keep the commission, you speak to buyers directly, and you control the pace. It needs you to be organised, which is exactly what the six-month preparation gives you. Our comparison of selling through NewOwner versus a business broker sets out the trade-offs honestly, including where a broker genuinely earns their fee.

Direct approach to trade buyers. In cleaning this is underrated. Regional facilities-management companies and larger local cleaners are always looking for contract books in their patch. A short, confidential approach to five or six of them can produce a better price than an open listing, because a trade buyer values your contracts at their margin, not yours. The risk is confidentiality: if word reaches your clients or staff before you're ready, you have a problem.

Whichever route you pick to sell a cleaning business, protect the confidential information. NDA before the client list goes anywhere. Client names redacted in the first pack, revealed at heads of terms. Staff told when the deal is close to certain, not when it's a possibility.

When you're ready to test the market, you can list your business on NewOwner and deal with buyers directly, or see the pricing first. If you want to talk through your specific position before committing to a route, get in touch.
