Every window cleaning round for sale and every window cleaning business on this page shows its area, its mix of work and either its monthly round value or its profit when we add it, because a one-person round is priced on what its customers pay each month and a business with vans and staff is priced on profit.

Published UK trade guides put most rounds at two to five times their monthly round value, and compact, well-priced four-weekly rounds at six to nine times, so a round billing £3,000 a month would typically be priced between £6,000 and £15,000, or £18,000 to £27,000 if it is tightly grouped. An owner-run window cleaning business usually sells for about one and a half to three times a year's adjusted profit, meaning profit with the owner's own pay and personal costs added back.
This section is about window cleaning businesses, which are larger than a single round, usually with several vans, employed or subcontracted cleaners, a mix of domestic and commercial customers and an owner who runs the business more than cleans for it. Commercial window work for offices, shops, schools and blocks of flats is often on a written contract or a regular schedule, and buyers look at those contracts in the same way as any commercial cleaning contract, checking notice periods, change-of-control wording and whether any single client provides too large a share of the turnover.
A multi-van business carries wages, vans, insurance and management costs that a one-person round does not, so it is priced on profit rather than on monthly round value, in the same way as other cleaning companies, and an owner-run window cleaning business usually sells for roughly one and a half to three times a year's adjusted profit, meaning profit with the owner's own pay and personal costs added back. Applying a round's monthly-value figures to a business with staff would leave those costs out, so a buyer should always ask for the accounts and a breakdown of profit by van or team. Employed cleaners move to the buyer on their existing terms under TUPE in an asset sale, and our page on commercial cleaning businesses for sale covers contract checks in more detail.
A round is priced on its monthly round value, meaning what the customers on the list pay in an average month for their regular cleans, multiplied by a figure that reflects how good the round is. On a four-weekly round there are thirteen cleans a year, so a round billing £2,770 for each full cycle has a monthly value of about £3,000, found by multiplying £2,770 by thirteen and dividing by twelve.

In pounds, a round with a monthly value of £3,000 would be priced at roughly £6,000 to £15,000 on the wider published range, and at £18,000 to £27,000 if it is compact, well priced and cleaned every four weeks. Asking prices on listings reach higher than either published range at the top end, and a buyer should treat an asking price as the seller's opening figure in a negotiation. You can test a round's figures with our window round valuation guide.
These are the checks a buyer should make on any round before agreeing a price, and a seller with a sound round will be glad to help with each one.
A seller who can show you all of this on paper is offering a round you can price with some confidence.
These are the signs a buyer should look out for when a round comes up for sale.
None of these rules a round out on its own, and some are simply reasons to offer a lower price, though a round showing several of them together usually needs more questions answered before any money changes hands.
The seller usually introduces the buyer to customers in person, by a card or letter through the letterbox, or by message for customers who pay through an app, telling them who will be cleaning their windows from which date and that the price and frequency stay as they are. Most buyers then work a trial period alongside the seller, often for a full cycle or two, so they learn the route, the access arrangements, the gate codes and which customers like a knock when the cleaner arrives.
Some customers will drop off whatever both sides do, so it is common to hold back part of the price until the round has been running under the new owner for an agreed period. The written agreement should set out how much is held back, for how long, how lost customers are counted, and how the held-back amount is reduced if more customers leave than the 5 to 10% buyers usually expect, so that the buyer is protected without the seller being penalised for ordinary losses. The agreement should also include the seller's promise not to clean windows for customers on the list, or nearby, for an agreed time after the sale.
Most rounds are run by one person, though if the round comes with an employee, the rules on TUPE when selling a cleaning business may move that person across to you on their existing terms.

UK trade guides (Cleaning Matters 2015, Window Cleaning Warehouse 2022) put most rounds at two to five times their monthly round value, with compact, well-priced four-weekly rounds reaching six to nine times. A round taking £2,000 a month would usually cost somewhere between £4,000 and £10,000, and more if it is tightly grouped and paid by card or direct debit. Asking prices on listings are often higher than the price a round finally sells for.
Buyers commonly expect 5 to 10% of customers to drop off after a round changes hands. Cash rounds and rounds built on the seller's personal friendships tend to lose more, while card and direct debit customers on a regular cycle tend to stay. Holding back part of the price until the round has settled protects you against losses beyond that.
It is safer not to, and most fair sales hold back part of the price until the round has run under the new owner for an agreed period. The held-back amount is then paid in full or reduced according to how many customers have stayed. Agree the rules in writing before you pay anything.
Monthly round value is what the customers on the list pay in an average month for their regular cleans. For a four-weekly round, add up one full cycle, multiply by thirteen and divide by twelve, since there are thirteen four-weekly cycles in a year. One-off jobs should be left out of the figure.
Yes, many rounds are bought by people new to the trade, though a longer trial period alongside the seller is sensible so you learn the route and the customers before working it alone. You will need your own equipment and public liability insurance in place before the handover date. A seller who agrees to stay available by phone for the first few weeks makes the start much easier.
