Buying a cleaning business in the UK usually costs roughly 1.5 to 3 times a year's adjusted profit for an owner-run company, and takes 6 to 9 months from first look to money changing hands, or 2 to 4 months for a window round or small domestic business.
The work that protects you is due diligence on contracts, staff, client concentration and the accounts. Most deals are paid for with a mix of the buyer's own cash, bank lending and part of the price paid to the seller over time.
There were 78,915 businesses in the UK cleaning, hygiene and waste industry in 2025, according to the British Cleaning Council, a figure that also takes in facilities management, waste and landscaping, and the cleaning businesses among them fall into a few distinct trades. Commercial contract cleaners suit buyers who want to manage people and clients and can fund a larger purchase, domestic cleaning agencies suit buyers comfortable with a local, relationship-led business, carpet cleaning businesses suit buyers happy to do skilled hands-on work at first, and window cleaning rounds for sale are the cheapest way in for someone who will do the cleaning themselves. The more important choice is often whether the business already has a supervisor or manager running the rota, because an owner-run business asks for your time from the first day while a managed one costs more and leaves you free to run it.
This table sets out the areas to examine before buying, what to ask the seller for, and what should make you pause.
| Area | What to ask for | What should make you pause |
|---|---|---|
| Contracts | Every written client contract, with fees, hours, notice periods and any change-of-control clause | Work with no written terms, short notice periods on large clients, or clauses letting clients leave when the owner changes |
| Staff and TUPE | Staff list with pay, hours, start dates, contracts and right-to-work checks | Pay below the National Living Wage of £12.71 an hour, high staff turnover, open grievances or tribunal claims |
| Client concentration | Turnover by client for the last two or three years | Any single client above about 15 to 20% of turnover |
| Accounts | Filed accounts, management accounts, bank statements and the owner's add-backs | Profit that does not match the bank, or personal costs added back without evidence |
| Accreditations | BICSc training records, ISO 9001 or 14001 certificates, SafeContractor or CHAS membership | Lapsed certificates, or accreditations held by the owner personally |
| Insurance | Public liability and employers' liability policies with claims history | Gaps in cover, repeated damage claims or unresolved complaints |
| Equipment | List of vans, machines and kit with age, condition and any finance owed | Old equipment needing early replacement, or hire purchase debts nobody mentioned |
| Reviews | Online review profiles, complaints log and client feedback | Falling ratings, recent run of complaints, or reviews naming the owner as the reason clients stay |
As an illustration, a £200,000 purchase might be paid with £60,000 of the buyer's cash, £100,000 of bank lending and £40,000 paid to the seller over two years, provided the business's profit comfortably covers the loan repayments and the deferred payments together.
The seller should introduce you personally to the largest clients and to every supervisor, attend a staff meeting where the change of owner is explained, and stay available for an agreed period, usually set out in the sale contract, to answer questions and help with any client who wavers. You also need the practical things transferred properly, including bank mandates, direct debit arrangements, payroll, the booking or scheduling system, the phone number, website and review logins, keys and alarm codes held for clients, and any supplier accounts for chemicals and equipment.
When you are ready to look, browse cleaning businesses for sale or register as a buyer to hear about new listings first.
Check the contracts and notice periods, the staff and their pay, the share of turnover from the largest clients, and whether the accounts match the bank statements. Accreditations, insurance, equipment and online reviews come next. The checklist on this page covers each area with what to ask for.
Yes, banks lend for business purchases on ordinary terms or under the government-backed Growth Guarantee Scheme. They look hardest at contract terms, client concentration and whether profit covers the repayments comfortably. You will usually need to put in some of your own cash as well.
Deferred consideration is part of the price that the seller agrees to receive in instalments after the sale instead of on the day. It reduces how much you need to raise up front and keeps the seller invested in a smooth handover. Some deals link it to clients or contracts staying in place.
Neither is better in every case, since a share purchase keeps contracts and staff with the company but brings its past liabilities with it. An asset purchase leaves those liabilities with the seller but needs client consent and moves staff under TUPE. Your solicitor and accountant will advise on the business you are buying.
You need enough cash to pay wages and running costs until clients pay you, which for commercial cleaning is often 30 days or more after invoice. Plan for at least one full payroll cycle on top of the purchase price. Lenders will ask how you have covered this.
