Professional window cleaning in the UK typically costs around £15–£25 for a small home and approximately £20–£40 for an average three-bedroom house per visit. Larger detached properties, conservatories, difficult access and specialist cleaning can push the price to £40–£100+.
However, window-cleaning prices are rarely based on the number of bedrooms alone. A three-bedroom bungalow with eight easily accessible windows may cost less than a two-bedroom townhouse with roof windows, large glazed doors and difficult rear access.
There is also an important difference between regular exterior window cleaning and a one-off intensive clean. A window cleaner visiting every four or eight weeks can usually work much faster than someone removing months or years of accumulated dirt for the first time.
So, how much does window cleaning cost in the UK in 2026? Here is what you should realistically budget, what affects the price and what to check before choosing a window cleaner.
How much does window cleaning cost in the UK in 2026?
These broad ranges are useful for budgeting:
| Window-cleaning service | Typical UK cost |
|---|---|
| Small flat/house exterior | £15–£25 |
| 2-bedroom house | £15–£30 |
| 3-bedroom house | £20–£40 |
| 4-bedroom house | £25–£50 |
| Large detached property | £40–£80+ |
| One-off window clean | £30–£100+ |
| Interior and exterior cleaning | Often £40–£100+ |
| Conservatory windows | Around £30–£80+ |
| Conservatory roof cleaning | Around £50–£150+ |
| Gutter/fascia/soffit cleaning add-on | Often £30–£100+ |
These are indicative ranges rather than fixed national prices.
Your actual quote depends on the number and size of windows, accessibility, frequency, location and exactly what you want cleaned.
How much does a window cleaner charge per house?
For many ordinary UK homes, around £20–£40 per regular visit is a realistic starting point.
But asking how much a window cleaner charges “per house” can be misleading.
Consider two three-bedroom properties.
House A has ten ordinary windows across two floors with easy access.
House B has fifteen windows, a conservatory, French doors, skylights and restricted rear access.
Both have three bedrooms.
The amount of work is completely different.
Professional window cleaners therefore usually consider the actual property rather than applying one universal price based solely on bedroom count.
How much does window cleaning cost for a 2-bedroom house?
For a typical two-bedroom property, you might pay approximately £15–£30 for regular exterior window cleaning.
A small terraced property with straightforward access may fall towards the lower end.
Expect more if the house has:
- unusually large windows;
- a conservatory;
- several glazed doors;
- roof windows;
- difficult rear access;
- substantial accumulated dirt.
Location also matters. Prices in London and some parts of the South East can be higher than in other areas of the UK.
How much does window cleaning cost for a 3-bedroom house?
For an average three-bedroom UK house, around £20–£40 per regular exterior clean is a sensible starting budget.
The exact amount depends much more on the glazing than the bedroom count.
A semi-detached three-bedroom house might have relatively straightforward windows.
A larger detached home could have:
- bay windows;
- patio doors;
- French doors;
- conservatory glazing;
- Velux-style roof windows;
- extensions.
Those additions increase the time required.
How much does window cleaning cost for a 4-bedroom house?
For a four-bedroom property, expect roughly £25–£50+ for a standard regular exterior clean.
Larger detached houses can cost significantly more.
If you have extensive glazing, the price might reach £60, £80 or beyond.
Instead of telling the window cleaner only that you have a four-bedroom house, give them photographs of:
front + rear + sides.
That makes remote quoting considerably easier.
How much does window cleaning cost for a large detached house?
For larger detached properties, professional window cleaning might cost £40–£80+ per visit, with particularly large or complicated homes potentially exceeding £100.
Large properties often contain more than simply extra windows.
They may also have:
- multiple storeys;
- extensions;
- rooflights;
- large bifold doors;
- conservatories;
- glass balustrades;
- difficult access.
At this point, a site-specific quotation is much more useful than any UK average.
Do window cleaners charge per window?
Some do, particularly for one-off or commercial work.
Others price the property as a complete job.
A cleaner might assess:
- number of windows;
- size;
- height;
- access;
- glazing type;
- frequency.
They then quote one total amount.
This can be easier for regular residential customers because you know exactly what each visit will cost.
If you receive a quote of £30 for the house, ask whether that includes all ordinary windows and doors rather than trying to reverse-engineer a price per pane.
How much does window cleaning cost per hour?
Some specialist or one-off window-cleaning jobs may be priced according to labour time, but routine residential rounds are often quoted per property.
If you are comparing window cleaning with other domestic cleaning work, our guide to how much a cleaner costs per hour in 2026 explains typical UK domestic-cleaning rates.
Remember that a window cleaner may use specialist equipment, purified water systems and vehicles, so their pricing structure does not necessarily match an ordinary house cleaner’s hourly rate.
What is normally included in window cleaning?
A standard exterior window-cleaning service may include:
- exterior glass;
- frames;
- sills;
- window edges.
But this varies between businesses.
Some cheaper services may concentrate mainly on the glass.
Others routinely wash frames and sills as part of every visit.
Ask before booking:
“Does your price include the glass, frames and sills?”
It is a simple question that prevents misunderstandings later.
Does window cleaning include the inside?
Usually not unless specifically requested.
Regular residential window cleaners commonly work on the exterior of the property.
Interior cleaning requires:
- entering the home;
- moving around furniture;
- protecting floors;
- accessing windows behind blinds or curtains;
- more detailed hand cleaning.
That takes considerably longer.
If you want both sides cleaned, say so when requesting the quote.
Do not assume “window cleaning” automatically means inside and outside.
How much does inside and outside window cleaning cost?
For a typical home, cleaning both interior and exterior windows might cost approximately £40–£100+, depending on property size.
Interior work can add substantially to the price because it is more labour-intensive.
The cleaner cannot simply use a long water-fed pole from outside.
They need access to every room.
You can reduce the time required by:
- clearing window sills;
- opening blinds;
- moving small objects;
- providing easy access.
If twenty windows each require several minutes of preparation before cleaning even begins, the labour quickly adds up.
Is regular window cleaning cheaper than a one-off clean?
Usually, yes.
This is one of the biggest factors affecting price.
Imagine a window cleaner visits every six weeks.
The windows have accumulated only a limited amount of normal dirt since the previous visit.
Now compare that with a property whose windows have not been cleaned for two years.
The cleaner may encounter:
- heavy grime;
- algae;
- cobwebs;
- bird mess;
- dirty frames;
- contaminated sills.
The first clean can take much longer.
Many businesses therefore charge more for an initial clean and then offer a lower regular-maintenance price.
How much does a one-off window clean cost?
A one-off residential window clean might cost roughly £30–£100+, depending on the property.
A one-off clean can be particularly useful:
- before selling a home;
- after buying a property;
- before an event;
- after building work;
- after a long period without cleaning.
If the windows are extremely dirty, tell the cleaner.
Do not request a quote for “normal window cleaning” and expect years of grime to be removed for the same price as a routine six-week visit.
How often should you have your windows cleaned?
There is no fixed rule.
Many households choose professional exterior cleaning approximately every:
4 weeks
6 weeks
8 weeks
or
12 weeks.
The best interval depends on your property.
Homes near busy roads, trees or the coast may accumulate dirt more quickly.
A sheltered property in a quiet residential area might remain presentable for much longer.
If budget is important, an eight- or twelve-week schedule may provide a good compromise.
How much does monthly window cleaning cost?
Suppose your cleaner charges £25 per visit.
Cleaning every four weeks works out at roughly:
13 visits per year × £25 = £325 annually.
That averages around £27 per month across the year.
At £35 per visit:
13 × £35 = £455 annually.
That is roughly £38 per month averaged across the year.
This is a better way to budget than thinking only about the individual visit.
Is cleaning every 8 weeks cheaper?
Yes, because you are paying for fewer visits.
For example:
£30 every four weeks = approximately £390 per year.
£30 every eight weeks = approximately £195 per year.
However, some cleaners may charge slightly more for less frequent visits because the windows accumulate more dirt.
Ask whether the price changes depending on frequency.
Why does the first window clean cost more?
Because the first visit can involve much more work.
A cleaner may need to remove long-term dirt from:
- frames;
- seals;
- sills;
- glass.
Once those areas are clean, future maintenance becomes much quicker.
For example, a business might quote:
First clean: £45
Regular clean: £28
That is not necessarily an attempt to overcharge you.
The first job may genuinely require substantially more labour.
How much does conservatory window cleaning cost?
Cleaning conservatory glazing can add approximately £30–£80+ to a job depending on its size and accessibility.
The vertical windows may be relatively straightforward.
The roof is usually the more complicated part.
A conservatory can contain a surprising amount of glass, so adding one to an ordinary house-cleaning quote can substantially increase the total.
Ask whether the quote covers:
conservatory sides
or
sides + roof.
They are not necessarily the same service.
How much does conservatory roof cleaning cost?
Professional conservatory-roof cleaning may cost around £50–£150+, depending on size, height and condition.
Roof panels can accumulate:
- algae;
- moss;
- bird mess;
- leaves;
- general dirt.
Access is also more complicated than ordinary ground-floor windows.
Never assume a window cleaner will climb directly onto a conservatory roof. Appropriate access methods depend on the structure and job.
Ask how the business plans to carry out the work safely.
Does window cleaning include Velux or roof windows?
Not necessarily.
Roof windows may require specialist access or suitable pole systems.
If you have them, mention them when requesting the quote.
A cleaner quoting from a photograph of the front of the house cannot know there are six rooflights on a rear extension.
Providing complete information avoids price changes on the day.
Does window cleaning include French doors and patio doors?
Often, but confirm it.
Large glazed doors increase the amount of glass significantly.
Modern properties can contain:
- French doors;
- sliding patio doors;
- large fixed glazing;
- bifold doors.
A wall of bifold glazing can contain as much glass as several ordinary windows.
It is reasonable for that to affect the quote.
How much does cleaning bifold doors cost?
If added to a regular window-cleaning visit, a modest set of bifold doors may add roughly £5–£20+, depending on their size and whether both sides are being cleaned.
Large glazed installations can cost more.
Again, photographs are useful.
The phrase “bifold doors” could mean three narrow panels or an enormous wall of glass.
What is water-fed pole window cleaning?
Many professional window cleaners now use water-fed pole systems.
Purified water is pumped through a telescopic pole to a brush at the window.
The cleaner scrubs the glass, frames and surrounding areas and then rinses them with purified water.
Because the water contains very low levels of dissolved minerals, the glass can be left to dry naturally without the mineral spotting associated with ordinary tap water.
The system also allows many upper-storey windows to be cleaned from ground level.
Why are my windows left wet after the cleaner finishes?
If your cleaner uses a purified-water system, this can be completely normal.
The windows are deliberately rinsed and left wet.
The purified water should dry naturally.
Do not immediately wipe them with a household cloth because doing so can transfer fibres or contamination back onto the glass.
If marks remain once the window is completely dry, contact the cleaner.
Traditional window cleaning vs water-fed pole: which is better?
Both methods can produce excellent results when used correctly.
Traditional cleaning
Typically involves:
- applicator;
- cleaning solution;
- squeegee;
- detailing cloths.
It is particularly useful for internal glass and accessible areas.
Water-fed pole cleaning
Can efficiently clean:
- exterior glass;
- frames;
- sills;
- upper-storey windows.
Neither method is automatically “better” in every situation.
The correct method depends on the property and type of cleaning required.
Can a window cleaner reach third-storey windows?
Potentially, depending on the equipment and access.
Modern water-fed pole systems can reach substantial heights from ground level.
However, not every window can safely or effectively be reached from every location.
Obstacles such as:
- extensions;
- conservatories;
- narrow alleys;
- overhead structures;
- neighbouring property;
can complicate access.
If you have unusually high windows, mention them when requesting a quote.
Does difficult access increase window-cleaning cost?
It can.
Imagine two identical windows.
One is directly above an open driveway.
The other sits behind a conservatory in a narrow enclosed garden.
The glass area is identical.
The work required to reach it is not.
Difficult access can increase:
- labour;
- equipment requirements;
- setup time.
This is why photographs are so useful for quotations.
Does window cleaning include frames and sills?
Often, but never assume.
Some window cleaners include frames and sills routinely.
Others offer glass-only or different service levels.
Frames can become particularly dirty where they have not been cleaned for years.
An initial frame restoration may therefore cost more than routine maintenance.
Ask exactly what “window clean” means before comparing prices.
Can window cleaners remove hard-water stains?
Normal window cleaning can remove ordinary dirt.
Hard-water deposits are different.
Minerals can build up on glass and become difficult to remove through routine cleaning alone.
Specialist restoration may be needed.
The same applies to:
- paint;
- cement;
- adhesive;
- silicone;
- construction residue.
If your windows need restoration rather than ordinary cleaning, send photographs before accepting a standard quote.
Does window cleaning after building work cost more?
Often, yes.
After-builders window cleaning can involve materials that are not present during normal maintenance.
These might include:
- plaster;
- paint;
- adhesive;
- stickers;
- cement residue;
- silicone.
Removing construction contamination from glass requires more care because aggressive scraping can potentially damage certain surfaces.
Tell the cleaner the property has recently undergone building work.
Do not book an ordinary maintenance clean and assume specialist residue removal is included.
Can a normal house cleaner clean windows?
Yes, particularly internal windows.
A domestic cleaner may be perfectly capable of cleaning accessible interior glass as part of a wider house clean.
However, upper-storey exterior windows normally require appropriate specialist equipment.
This is where a dedicated window-cleaning service becomes more practical.
For general domestic cleaning rates, see our guide to how much a cleaner costs per hour in 2026.
Is window cleaning included in a deep clean?
Sometimes internal window cleaning is included in a deep-cleaning package.
Exterior windows often are not.
This varies between cleaning companies.
If you are booking a larger whole-house clean, ask whether the quote includes:
inside windows + outside windows + frames + sills.
Our guide to deep cleaning vs regular cleaning explains why specialist extras should not automatically be assumed to form part of a domestic cleaning package.
Is DIY window cleaning cheaper?
Yes.
For ground-floor windows, DIY cleaning can be extremely inexpensive.
You need little more than appropriate cleaning equipment and your time.
The advantage of professional cleaning becomes more obvious when dealing with:
- upper floors;
- numerous windows;
- difficult access;
- conservatories;
- limited time;
- regular maintenance.
Avoid taking unnecessary risks to save £20 on an upstairs window.
If safe access is difficult, professional equipment can make much more sense.
Should you clean windows before selling your house?
It can be worthwhile.
Clean glass allows more natural light into rooms and improves the appearance of both the interior and exterior.
Compared with many home-improvement jobs, window cleaning is relatively inexpensive.
If you are preparing for property photographs or viewings, a one-off interior and exterior clean may provide better visual value than many more expensive cosmetic changes.
Should you clean windows after moving into a property?
It is a convenient time.
If the previous owner or tenant did not clean the windows recently, a one-off initial clean can establish a good baseline.
You can then decide whether you want a regular four-, eight- or twelve-week service.
Ask the cleaner for both prices:
one-off first clean
and
ongoing maintenance price.
The difference may help you decide whether regular cleaning is worthwhile.
Do window cleaners work in the rain?
Often, yes.
Modern professional window cleaning can be carried out during light rain.
Rain itself is not necessarily what makes windows dirty. Dust, traffic pollution, bird mess and other contamination play a much larger role.
Heavy rain, strong winds, thunderstorms or other unsafe conditions may cause the cleaner to postpone the visit.
Policies vary between businesses.
Do I need to be home for a window cleaner?
For exterior-only cleaning, often not.
If the cleaner has safe access to all required areas, they may complete the job while you are away.
Many regular customers pay electronically.
However, if access requires:
- locked gates;
- moving vehicles;
- entering the property;
- opening windows;
you may need to make arrangements beforehand.
Interior cleaning obviously requires access to the house.
How do window cleaners charge for regular customers?
Regular window-cleaning businesses often operate scheduled rounds.
For example:
every 4 weeks
or
every 8 weeks.
Payment may be taken by:
- bank transfer;
- card;
- Direct Debit;
- online payment;
- cash.
Ask whether the service automatically continues until cancelled and what notice is required if you want to stop.
Why are some window cleaners much cheaper?
Several explanations are possible.
A cheaper business may:
- operate very efficient local rounds;
- have lower overheads;
- clean only exterior glass;
- exclude frames;
- use different equipment;
- offer a shorter service.
Or they may simply charge less.
A higher price does not automatically mean higher quality either.
This is why you should compare the actual service.
Our guide to comparing quotes properly explains why headline price alone can be misleading when hiring any local professional.
Should I choose the cheapest window cleaner?
Not automatically.
Suppose you receive:
Quote A: £18
Quote B: £26
If both include the same windows, frames and sills at the same frequency, Quote A may genuinely be better value.
But perhaps Quote A covers only glass.
Quote B includes:
- frames;
- sills;
- doors;
- more difficult rear windows.
Then the £8 difference looks very different.
Compare scope + frequency + reliability + total price.
What should you ask a window cleaner before hiring them?
Before booking, establish:
- What windows are included?
- Are frames included?
- Are sills included?
- Are glazed doors included?
- Are roof windows included?
- Is the price for exterior only?
- How much extra is interior cleaning?
- Is the first clean more expensive?
- How frequently will you visit?
- Is there a minimum charge?
- What happens during bad weather?
- How do I pay?
- Is VAT included where applicable?
For a larger property, send photographs.
It can save both you and the cleaner a wasted visit.
How can you save money on window cleaning?
Regular rounds are usually the most economical option if you want windows professionally maintained throughout the year.
You can also save by choosing a sensible frequency.
If your windows remain presentable for eight weeks, paying for cleaning every four weeks may be unnecessary.
Other ways to reduce costs include:
- keeping access clear;
- unlocking gates beforehand;
- combining conservatory cleaning with the main visit;
- using exterior-only professional cleaning;
- cleaning easy ground-floor interior windows yourself.
The cheapest option is not necessarily the lowest quote. It is the service that gives you the result you want without paying for work you do not need.
How much should I budget for window cleaning?
For an ordinary UK home in 2026, a sensible starting budget is:
Small home: £15–£25 per visit
2-bedroom house: £15–£30
3-bedroom house: £20–£40
4-bedroom house: £25–£50+
Large detached property: £40–£80+
One-off intensive clean: £30–£100+
Interior + exterior: £40–£100+
If you have a conservatory, extensive bifold doors or difficult high-level glazing, allow more.
And always get an actual quote for your property before budgeting around a national average.
Window cleaning cost UK: the verdict
So, how much does window cleaning cost in the UK?
For many ordinary homes, professional exterior window cleaning costs roughly £15–£50 per visit, with a typical three-bedroom house often somewhere around £20–£40.
Large detached homes, conservatories, interior cleaning and difficult-access windows can push the total considerably higher.
The first clean may also cost more than regular maintenance because the cleaner is removing accumulated dirt rather than simply maintaining already-clean windows.
When comparing prices, establish exactly what is included. A £20 glass-only clean and a £30 service covering glass, frames, sills and doors are not necessarily competing offers for the same job.
If you need regular or one-off window cleaning, you can find local window cleaners and cleaning professionals through The Right Guy. Give professionals photographs of the property and mention conservatories, roof windows or difficult access so you can compare realistic quotes for the same work.
