Window Cleaning Prices in the UK and What Affects Them

In 2026, a regular exterior visit for most UK homes costs roughly £12 to £60 outside London, and up to about £70 in London and the South East. An average residential visit usually falls between £25 and £40. Window cleaning prices depend mostly on the size of your house, where you live, and how often the cleaner calls.

What window cleaners charge in 2026

Most domestic window cleaning is priced per visit, not by the hour. Cleaners work on a round system, meaning the same person returns on a set cycle of four, six or eight weeks. The price per visit on a regular cycle is usually lower than the price for a single visit. The cost is based on the number and type of windows, the height of the property, and how easy the glass is to reach.

Prices are noticeably higher in London and the South East to cover higher running costs. You will also pay more for the very first clean. A first-time deep clean often costs 50% to 100% more than a regular visit. This is because the cleaner has to remove built-up dirt, green algae and old soap residue before they can maintain the glass properly.

Window cleaning prices by house type

The easiest way to benchmark a quote is to look at the size of your property. A terraced house with eight to ten windows takes less time to clean than a large detached home with twenty windows, and the price reflects this. A typical regular visit takes 20 to 40 minutes for a terraced house, while a detached house usually takes 45 to 90 minutes.

The figures below show published guide prices for a regular exterior clean by property size.

These are typical published prices for 2026, and local quotes will differ based on your exact property. If you have an unusual number of windows for your house type, expect the quote to move up or down accordingly.

Why regular cleans cost less than one-off visits

Window cleaners build their business around regular rounds. When they group jobs in the same neighbourhood on the same day, they save fuel and driving time. They pass these savings on to you if you agree to a predictable, regular schedule.

A one-off clean breaks this pattern and requires a dedicated trip. The glass is also likely to be dirtier, meaning the cleaner spends longer scrubbing and rinsing. A standard regular clean usually takes 30 to 60 minutes in total, whereas a deep clean can take one to three hours.

The table below shows how the frequency of visits affects the price for a typical three-bed semi-detached house.

These are typical published prices for 2026, and your local quotes will differ. If you cancel a regular service after just one or two visits, the cleaner has effectively done a deep clean for a regular round price. Be clear from the start if you only want a single visit.

What extras add to the bill

A standard quote usually covers the outside of your main house windows. Most cleaners will wash the frames and sills as part of a modern water-fed pole clean, but you should always ask to be sure. If you want anything else cleaned, you must ask for it to be added to the price.

Cleaning inside windows takes more care and time, as the cleaner must protect your floors and furnishings. Glazed doors, fascias, gutters and roof glass also add to the final bill.

These are typical extra costs you might see on top of a standard visit in 2026:

• Inside main windows add £10 to £15
• Roof windows or skylights add £10 to £40
• A conservatory with a glass roof adds £10 to £40
• French doors or glass panels add £5 to £10 each

If you live in London or the South East, a conservatory or skylight add-on can cost between £15 and £50. If you are unsure what is covered, ask the cleaner to list the extras before they start work. Knowing what window cleaning services include will help you check you are comparing like with like.

How location and access change the price

Your postcode plays a large part in the price you pay. Published price guides put London and the South East above the rest of the UK.

Access around your property also matters. A cleaner needs a clear path to bring their equipment into your back garden. If you live in a terraced house with no rear access, they may have to bring a wet brush and hose through your hallway, which takes longer and requires more care. Parking restrictions or permit zones add time and cost to the job.

Obstacles outside your home can alter the quote too. A large ground floor extension might make it difficult to reach the windows above it. Health and safety rules also play a part. Industry guidance produced with the Health and Safety Executive (HSE) states that water-fed poles must not be used near overhead power lines. You should point out any overhead cables to the cleaner when they arrive to quote.

How window cleaners work out a quote

A professional cleaner will usually visit your property to look at the glass before giving a final price. They count the total number of windows, but they also look at the style of the frames. Small panes, leaded lights and sash windows take longer to clean than large, single panes of modern glass.

They will also decide which cleaning method is best for your home. Traditional cleaning uses an applicator, a squeegee and a cloth to leave the glass dry immediately. If they use water-fed pole window cleaning, they use a telescopic pole with a brush head, fed with purified water from a tank in a van or a trolley. The glass is scrubbed, rinsed and left wet. Because the minerals have been filtered out, the water dries without leaving marks.

Many cleaners now work from the ground using poles. The Work at Height Regulations 2005 require work at height to be properly planned, done by competent people and avoided where reasonably practicable. Ladders are not banned, however. The HSE states that ladders can be a sensible option for low-risk, short-duration work, which includes domestic window cleaning on lower floors. The law asks for the cleaner to be competent, not to hold a formal qualification.

Commercial work is different, normally quoted per site and run as a contract with an agreed frequency and a written risk assessment and method statement. Taller buildings may need powered access platforms or rope access.

Is the cheapest quote the best choice?

A very low price can be a warning sign. If a cleaner quotes half the typical rate for your area, they have to work twice as fast to earn a living. This often means a rushed job, streaky glass, missed sills and dirty frames.

It can also mean the cleaner is cutting corners on their business costs. Employers' liability insurance is compulsory if a window cleaning business has employees. Public liability insurance is not a legal requirement, but it is the cover that pays out if a cleaner damages your property, breaks a window or injures someone. You should always ask to see a current certificate before they start work.

In Scotland, most councils require window cleaners to hold a specific licence under the Civic Government (Scotland) Act 1982. Requirements vary by council, but licence holders must carry identification. Cleaners elsewhere in the UK are not licensed in this way. Membership of a trade body is another positive sign. The Federation of Window Cleaners is a non-profit trade body established in 1947. It has a code of practice, a safety accreditation scheme and offers training. Membership is voluntary, so you should treat it as one good sign among several.

Watch out for these common problems before you hire:

• Cold callers who claim to be your usual cleaner and ask for cash at the door
• Cleans carried out without any agreement, followed by a demand for payment
• Cleaners who ask for payment for several months in advance
• Quotes that leave out the frames, sills, doors or conservatory
• Judging a water-fed pole clean entirely on the first visit, as it can leave spotting until old soapy residue is fully rinsed away

Taking time to find a good local window cleaner will save you money and frustration in the long run.

How and when you pay

A professional cleaner will agree a price with you before they wash a single pane of glass. You must know whether you are being given a quote or an estimate. A quote is a fixed price that cannot be exceeded without a legitimate reason, such as you asking for extra work. An estimate is an educated guess, though the final bill must still be reasonable.

Payment methods have changed in recent years. While some traditional cleaners still collect cash at the door in the evening, most modern businesses prefer bank transfers, direct debits or automated payment links sent by text message after the clean. This stops you having to wait in, and it stops the cleaner having to chase unpaid bills. You should pay promptly after each visit once you are happy with the work.

Your rights if the work is not up to standard

You have legal protections when you hire a tradesperson to work on your home. Under the Consumer Rights Act 2015, a service must be carried out with reasonable care and skill. If your windows are left covered in streaks, or the frames are left dirty after you agreed they would be cleaned, the work has not met this standard.

If a service is not done with reasonable care and skill, you can ask for it to be put right or for a refund. Raise the problem politely with the cleaner first. Most reputable businesses will happily return to re-clean a window if they have made a genuine mistake.

You also have rights if you change your mind. A service arranged online, by phone or off-premises carries a 14-day cooling-off period starting the day after the contract is made. This applies to agreements made on the doorstep where the cost is more than £42. If you cancel a service within this period, but the cleaner has already started the work at your request, you must pay for what was provided before you cancelled.

Common questions

How much does a window cleaner cost?

An average residential visit costs between £25 and £40, depending on the size of your property and where you live. Terraced houses sit at the lower end of the scale, while large detached houses cost more.

How much does a window cleaner charge for a one-off clean?

Published 2026 guides put a one-off clean for a three-bed semi at £35 to £55 and one-off or deep cleans more generally at £40 to £90, depending on the size of the house and the state of the glass. A first-time clean after a long gap takes much longer to scrub away heavy dirt, so it normally costs 50% to 100% more than a regular maintenance visit.

Are window cleaning rates higher for a conservatory?

Yes, adding a conservatory roof to a regular clean increases the bill. A conservatory with a glass roof typically adds £10 to £40 to the price, though this add-on can cost up to £50 in London and the South East.

Do window cleaner prices include the frames and sills?

Most window cleaners include the frames and sills in their standard price, especially if they use a water-fed pole system. You should always ask the cleaner to confirm exactly what the quote covers before you agree to the work.

Next steps before you book
