If you want a straight answer, most UK homeowners should expect to pay somewhere between £15 and £50 for a regular outside window clean, with smaller flats and terraces often sitting at the lower end and larger detached homes costing more. A one-off clean, an inside-and-outside clean, a conservatory roof clean, or a property with awkward access can push the price well beyond that.
Window washing is one of those services where the price can look confusing because two similar-looking houses may not cost the same. One property might have easy parking, simple modern windows and clear side access. Another might have rear access through the house, a glass extension, Georgian panes, roof lights and windows over a conservatory. From the pavement, both homes may look like ordinary houses, but from the cleaner’s point of view they are completely different jobs.
This is why most professional window cleaners do not price purely by bedroom count. They look at the number of windows, the height, the access, the window style, the cleaning frequency, the condition of the glass and whether the quote includes frames, sills, doors or internal panes. A cheap maintenance clean on a regular round is not the same thing as a first clean after two years of dirt, algae and bird mess.
Average UK Window Washing Prices
The table below gives a practical guide to what you might pay for domestic window washing in the UK. These are not fixed prices, but they are useful ranges for understanding whether a quote feels realistic.
| Property type | Outside only | Inside and outside | Approximate window count | Pricing notes |
|---|---|---|---|---|
| Small flat | £15–£30 | £25–£50 | 4–8 | Access matters more than size, especially above ground floor |
| One-bed house | £15–£30 | £30–£55 | 6–10 | Usually quick if front and rear access are simple |
| Two-bed terrace | £20–£40 | £35–£65 | 8–12 | Rear access can affect the price |
| Three-bed semi-detached | £25–£50 | £45–£85 | 10–16 | A common UK domestic window cleaning job |
| Four-bed detached | £35–£75 | £65–£120 | 16–24 | More elevations, more glass and more setup time |
| Bungalow | £20–£45 | £35–£75 | 8–18 | Single-storey access can keep the price down |
| Three-storey townhouse | £35–£80 | £65–£130 | 12–22 | Height and reach increase the cost |
| Large detached property | £60–£120+ | £100–£200+ | 25+ | Usually needs a bespoke quote |
For a standard outside clean, many homes fall into the £25 to £50 range. Smaller properties may be below this, while large homes, difficult access and one-off cleans can sit much higher. If a quote appears expensive, it is usually because the cleaner has spotted extra time, height, dirt, risk or access problems that are not obvious from the basic property type.
Price Per Property vs Price Per Window
Most domestic window cleaners quote per property because it is simpler for regular round work. Commercial cleaners, apartment block contractors and some one-off services may quote per pane, especially where the number of glass sections varies heavily.
| Pricing method | Typical UK range | Commonly used for | Watch out for |
|---|---|---|---|
| Per property | £15–£75 for many homes | Regular domestic cleaning | Make sure frames, sills and doors are included if you expect them |
| Per external pane | £1–£3 per pane | Flats, shopfronts, one-off jobs | Georgian or small-pane windows can become expensive |
| Per internal pane | £2–£5 per pane | Inside cleaning, offices, deep cleans | Internal work is slower because of furniture and flooring |
| Hourly rate | £25–£40 per hour | One-off jobs, specialist cleaning | Ask for an estimated total, not just the hourly figure |
| Bespoke quote | Varies widely | Large homes, commercial sites, high-level glass | Access equipment, risk and insurance affect the price |
Per-property pricing is usually best for normal houses because it gives you a clear cost before the job starts. Per-window pricing can be fair for unusual properties, but it can also climb quickly if you have lots of small panes, decorative glazing, sash windows, French doors or internal glass panels.
What Affects the Cost of Washing Windows?
Window cleaning prices are mainly driven by time, access and difficulty. The glass itself is only part of the job. A cleaner also needs to move equipment, reach each elevation safely, rinse frames, deal with dirty sills, check the finish and sometimes work around gates, cars, extensions, flower beds, pets or tenants.
| Cost factor | Why it changes the price | Example impact |
|---|---|---|
| Number of windows | More glass means more cleaning time | A 20-window detached home costs more than an 8-window terrace |
| Height | Higher windows need poles, ladders or access planning | Three-storey townhouses usually cost more |
| Access | Locked gates, narrow alleys and rear access through the home slow the job down | A simple £30 clean may become £40–£50 |
| Window style | Leaded, Georgian and sash windows take longer | Small panes can cost more than large plain panes |
| Dirt level | Heavy algae, cobwebs and bird mess take extra passes | First cleans often cost more |
| Cleaning frequency | Regular glass is quicker to maintain | Four-weekly cleans are usually cheaper than quarterly cleans |
| Location | Parking, labour rates and travel time vary by region | London and the South East often sit higher |
| Extras | Conservatories, skylights, solar panels and fascias add time | Add-ons are usually priced separately |
The cleaner is not only pricing the minutes spent on the glass. Their quote has to cover travel, equipment, purified water systems, insurance, fuel, admin, payment processing, route planning and the fact that some jobs take longer than expected.
Regular Clean vs One-Off Clean
A regular window clean is usually the cheapest option per visit. Once a property is on a four-weekly, six-weekly or eight-weekly schedule, the glass is easier to maintain and the cleaner can build the job into a route. One-off cleans are less predictable, so they are normally priced higher.
| Cleaning frequency | Typical price effect | Why it changes |
|---|---|---|
| Every 4 weeks | Base price | Glass stays under control and the job fits neatly into a round |
| Every 6 weeks | +5% to +15% | Slightly more dirt builds up between visits |
| Every 8 weeks | +10% to +25% | Longer gaps mean more grime, especially in winter |
| Every 12 weeks | +20% to +40% | The clean becomes closer to a light restoration job |
| One-off clean | +50% to +100% | More unknowns, more dirt and no repeat booking value |
| First clean after neglect | +50% to +150% | Frames, sills and glass may need heavier work |
A house that costs £30 every four weeks might cost £40 every eight weeks and £60 or more as a one-off clean. That does not mean the cleaner is charging randomly. It usually means the job will take longer, create more disruption in the schedule and involve more stubborn marks.
First Clean Prices
First cleans are often misunderstood. A new customer may expect the regular maintenance price straight away, but the first visit often involves much more work. The cleaner may need to wash frames thoroughly, remove cobwebs from corners, rinse vents, clear heavy sill dirt and go over the glass more than once.
| Normal regular price | Likely first clean price | When this applies |
|---|---|---|
| £20 | £30–£40 | Small home with moderate dirt build-up |
| £30 | £45–£60 | Typical house not cleaned for several months |
| £40 | £60–£80 | Larger home, algae on frames or awkward access |
| £60 | £90–£120+ | Large property, neglected glass or multiple extras |
A first clean is not always a deep restoration clean. Some marks, such as hard water staining, cement splashes, paint specks and damaged glass, may need specialist treatment and may not be included in a normal window washing quote.
Outside Window Washing Costs
Outside-only window cleaning is the standard service for many homes. It usually includes external glass and may include frames, sills and doors, depending on the cleaner. Many modern services use water-fed poles with purified water, which allows upper windows to be cleaned from the ground and leaves the glass to dry naturally without mineral spotting.
| Outside cleaning job | Typical price range | Notes |
|---|---|---|
| Front windows only | £10–£25 | Common for shops, terraces or properties with rear access issues |
| Front and rear terrace | £20–£40 | Price depends heavily on access |
| Semi-detached house | £25–£50 | Often includes side windows if reachable |
| Detached house | £35–£75 | More elevations and more movement around the property |
| Large country-style home | £60–£120+ | Usually quoted after photos or a visit |
| External doors and patio glass | Included or +£5–£20 | Depends on the amount of glass |
Outside cleaning gives the biggest visible improvement because exterior glass collects rain marks, traffic film, dust, pollen, bird mess, cobwebs and general weather grime. For many homes, a regular outside clean is enough, with internal cleaning booked less often.
Inside Window Washing Costs
Inside window cleaning normally costs more than people expect because it is slower and more careful work. The cleaner has to protect flooring, avoid furniture, work around blinds and curtains, and detail edges by hand. Water-fed pole systems are not used indoors in normal homes, so the process is more manual.
| Internal cleaning item | Typical price range | Why it costs more |
|---|---|---|
| Standard internal panes | £2–£5 per pane | More detailing and careful handling |
| Inside and outside house clean | 1.5x to 2.5x outside-only price | Two different cleaning processes |
| Patio doors or bi-folds | £5–£25 extra | Large glass panels show smears easily |
| High stairwell window | £10–£40 extra | Access inside the home can be awkward |
| Internal glass partitions | Bespoke | Usually priced by time and pane count |
Many homeowners book internal cleaning once or twice a year rather than every visit. Fingerprints, pet nose marks, condensation marks and cooking film build up more slowly than outside dirt, so internal glass usually does not need the same cleaning schedule.
Regional Window Cleaning Price Differences
Location affects pricing because labour costs, parking, travel time and route density vary. A cleaner working in London, Surrey or other expensive areas may need to charge more than one working in a lower-cost town with compact rounds and easy parking.
| Region | Typical three-bed semi outside clean | Pricing comment |
|---|---|---|
| London | £30–£60 | Parking, congestion and labour costs can raise prices |
| South East | £25–£55 | Often above national average |
| South West | £25–£50 | Depends heavily on towns, villages and travel time |
| Midlands | £20–£45 | Often mid-range for standard domestic homes |
| North West | £18–£40 | Route density can keep prices competitive |
| North East | £15–£35 | Often lower for simple regular cleans |
| Scotland | £18–£45 | City and rural pricing can vary widely |
| Wales | £18–£40 | Access and travel distance matter |
Regional tables should only be used as a guide. A rural property in a cheaper region can cost more than a compact urban property in a higher-cost region if the cleaner has to travel further or spend longer on access.
Add-On Window Cleaning Costs
Many quotes start with the standard windows, then add extra items separately. This is normal because conservatories, skylights, roof lanterns and solar panels can take as long as several normal windows.
| Add-on service | Typical extra cost | Notes |
|---|---|---|
| Conservatory side windows | £15–£40 | Usually easier than the roof |
| Conservatory roof clean | £40–£150+ | Algae, moss and roof bars add time |
| Roof lantern | £15–£60 | Access and height decide the price |
| Velux or skylight | £5–£15 each | Higher or awkward roof lights cost more |
| Solar panel cleaning | £5–£15 per panel | Often booked as a separate service |
| uPVC frame deep clean | £30–£150+ | More detailed than a normal window clean |
| Fascias and soffits | £50–£200+ | Usually priced by property size |
| Gutter clearing and window bundle | £80–£250+ | Depends on gutter length and blockage level |
| Glass balustrades | £20–£100+ | Smears show easily, so detailing matters |
Always check whether extras are included. Some homeowners say “clean the windows” and assume doors, frames, sills, conservatory glass and skylights are covered. The cleaner may see those as separate parts of the job.
Conservatory Cleaning Prices
Conservatories deserve their own section because they can change the quote quickly. The side glass is often straightforward, but the roof can be dirty, slippery, awkward and time-consuming. Roof bars trap algae, moss, leaves and old dirt. Polycarbonate panels also need care because they can mark or become brittle with age.
| Conservatory job | Typical price range | What affects the quote |
|---|---|---|
| Small conservatory windows only | £15–£30 | Side glass only, light dirt |
| Medium conservatory windows only | £25–£50 | More panels and door glass |
| Small roof clean | £40–£80 | Light algae and easy access |
| Large roof clean | £80–£150+ | More panels, heavier dirt and awkward reach |
| Full conservatory clean | £100–£250+ | Roof, sides, frames, doors and detailing |
A cheap conservatory price may only include the side glass. A full clean that includes the roof, finials, gutters, frames and doors will cost more because it is a much bigger job.
Domestic vs Commercial Window Washing Prices
Commercial window cleaning is priced differently because it may involve public access, trading hours, insurance requirements, risk assessments, method statements and more formal scheduling. A small shopfront can be cheaper than a house, while a multi-storey building can cost hundreds or thousands.
| Commercial property type | Typical price range | Pricing basis |
|---|---|---|
| Small shopfront | £15–£50 per visit | Size, frequency and location |
| Restaurant or café frontage | £20–£80 per visit | Grease, fingerprints and trading hours matter |
| Low-level office | £50–£250 per visit | Pane count and internal glass affect cost |
| School or care home | £150–£1,000+ | Usually quoted as a contract |
| Apartment block communal glass | £100–£800+ | Access, height and shared areas matter |
| High-rise or rope access work | £500–£5,000+ | Specialist access, insurance and safety planning |
Commercial jobs may also require early morning work, weekend access, public liability documents, RAMS, IPAF-trained operatives, rope access technicians or water-fed pole systems capable of reaching greater heights. Those requirements increase the price because the risk and equipment level are higher.
Water-Fed Pole vs Traditional Window Cleaning
The cleaning method does not always change the price dramatically for a normal house, but it can affect what is included and how the job is carried out. Water-fed pole cleaning is now very common in the UK because it lets cleaners reach upper windows from the ground using purified water.
| Method | How it works | Cost impact | Best for |
|---|---|---|---|
| Water-fed pole | Purified water is pumped through a brush on a telescopic pole | Usually standard price | Regular outside cleans, upper windows, frames and sills |
| Traditional squeegee | Applicator, solution and squeegee by hand | Similar or slightly higher if ladders are needed | Internal glass, shopfronts, detailed finishing |
| Ladder work | Cleaner accesses windows directly | May increase price due to time and risk | Specific windows where poles are unsuitable |
| Rope access | Technicians descend from the building | Much higher | High-rise commercial buildings |
| MEWP or cherry picker | Powered access platform | Much higher | Large commercial sites or awkward high-level glazing |
Water-fed pole cleaning can leave glass looking wet at first because the purified water is designed to dry naturally. If the water is properly purified and the glass has been rinsed correctly, it should dry clear.
Example Window Cleaning Price Scenarios
The following examples show how prices can change in real situations. They are not quotes, but they explain why one property costs more than another.
| Scenario | Property details | Likely fair price | Why |
|---|---|---|---|
| Regular small terrace | 8 windows, front and rear, easy access, six-weekly clean | £20–£35 | Straightforward round work |
| Three-bed semi | 14 windows, patio doors, frames included, four-weekly clean | £25–£45 | Typical domestic maintenance clean |
| First clean after 12 months | Same three-bed semi, dirty frames and sills | £45–£80 | Extra time needed on first visit |
| Four-bed detached | 22 windows, side access, two sets of patio doors | £45–£85 | More elevations and more glass |
| Townhouse | Three storeys, rear windows above extension | £50–£100 | Height and reach increase difficulty |
| Inside and outside clean | Three-bed semi, internal panes included | £60–£100 | Internal work is slower and more detailed |
| Conservatory roof add-on | Medium conservatory with algae on roof bars | £60–£130 extra | Roof cleaning is separate from normal windows |
| One-off pre-sale clean | Detached home, inside and outside, light dirt | £100–£200+ | Full-property presentation clean |
These scenarios also show why regular customers often get better value. A cleaner who knows the property, has regular access and keeps the glass maintained can usually complete the job faster.
What Should Be Included in the Price?
Do not assume every quote includes the same service. Some cleaners include frames, sills and doors as standard. Others quote mainly for glass and charge extra for detailed frame work or heavily soiled uPVC.
| Item | Usually included? | Clarify before booking |
|---|---|---|
| External glass | Yes | Confirm all elevations are included |
| Window frames | Often | Ask whether this is a light wash or deep clean |
| Window sills | Often | Important on first cleans and older properties |
| Front and back doors | Sometimes | Glass doors may be counted as extra windows |
| Patio doors | Sometimes | Large glass panels can affect price |
| Internal windows | No | Usually a separate price |
| Conservatory roof | No | Almost always an add-on |
| Skylights and roof lanterns | Sometimes | Depends on reach and access |
| Hard water stain removal | No | Often needs specialist treatment |
| Paint, cement or render removal | No | May require careful scraping or restoration work |
A slightly higher quote may be better value if it includes glass, frames, sills and doors. A cheaper quote may not be wrong, but you need to understand exactly what is covered.
How To Avoid Overpaying for Window Washing
The aim is not to find the cheapest possible window cleaner. The aim is to get a fair price for the actual work. A very cheap clean can become poor value if frames are missed, visits are unreliable or the cleaner rushes the job.
| Before you accept a quote | Why it matters |
|---|---|
| Ask whether it is a first-clean price or regular price | The first clean may be much higher |
| Confirm inside, outside or both | Many quotes are outside-only by default |
| Ask whether frames and sills are included | This changes the value of the quote |
| Mention conservatories, skylights and roof lanterns | These are often priced separately |
| Send photos of all sides of the property | This reduces surprise price changes |
| Explain access issues upfront | Locked gates, rear access and extensions affect time |
| Check the cleaning frequency | Four-weekly prices are usually lower than one-off prices |
| Avoid judging by price alone | Reliability, insurance and care matter |
If you want the most accurate price, send front, rear and side photos of the property and explain what you want cleaned. That gives the cleaner enough information to quote properly instead of guessing.
Fair Price Summary
For most UK homes, this is a sensible way to judge a window washing quote.
| Job type | Fair price guide |
|---|---|
| Small flat outside clean | £15–£30 |
| Two-bed terrace outside clean | £20–£40 |
| Three-bed semi outside clean | £25–£50 |
| Four-bed detached outside clean | £35–£75 |
| Large detached outside clean | £60–£120+ |
| Inside and outside clean | 1.5x to 2.5x outside-only price |
| First clean | 50% to 100% more than regular price |
| Conservatory roof clean | £40–£150+ |
| Commercial shopfront | £15–£50 per visit |
If your quote is much higher than these ranges, there may be a good reason. The property may have awkward access, high-level glass, lots of small panes, heavy dirt, difficult parking or extra services included. If your quote is much lower, check what is included and whether the cleaner is properly set up for the job.
FAQs
How much does it cost to wash windows in the UK?
Most UK homes pay around £15 to £50 for a regular outside window clean, although larger properties can cost more. A small flat or simple terrace may sit at the lower end, while detached houses, townhouses and homes with extensions usually cost more.
The price depends on the number of windows, access, cleaning frequency and whether frames, sills, doors or internal panes are included. A one-off or first clean is normally more expensive than a regular maintenance visit.
How much should a three-bed house cost for window cleaning?
A three-bed semi-detached house often costs around £25 to £50 for outside window cleaning. If the property has easy access and is cleaned regularly, the price may sit closer to the lower end.
If the same house needs inside cleaning, has a conservatory, includes roof lights or has not been cleaned for a long time, the price can rise. A first clean for a three-bed home may cost £45 to £80 or more depending on condition.
Is window cleaning priced per window?
Some cleaners price per window, but most domestic window cleaners prefer a fixed price per property. Per-property pricing is easier for regular round work because the cleaner can judge the whole job, including access and setup time.
Per-window pricing is more common for flats, commercial buildings, shopfronts and one-off work. It can become expensive if the property has lots of small panes, Georgian windows, sash windows or internal glass panels.
Why is the first window clean more expensive?
The first clean often takes longer because the cleaner has to remove old dirt from the glass, frames, vents, corners and sills. Cobwebs, algae, bird mess and traffic film can build up when windows have not been maintained.
Once the first clean is done, future visits are usually quicker. That is why many window cleaners charge a first-clean price, then offer a lower regular maintenance price afterwards.
How often should you have your windows washed?
Most homes are cleaned every four, six or eight weeks. Properties near busy roads, trees, farmland or the coast may need more frequent cleaning because glass gets dirty faster.
If you leave windows for several months, each clean may cost more because the dirt has had longer to build up. Regular cleaning is usually better value if you want the property to stay presentable throughout the year.
Does rain make newly cleaned windows dirty again?
Rain does not usually make clean windows dirty on its own. The marks often appear when rain moves existing dirt, dust or pollution across the glass, or when surrounding frames and sills have not been cleaned properly.
Water-fed pole cleaning uses purified water, which is designed to dry clear. The glass may look wet when the cleaner leaves, but it should dry without mineral marks if the rinse has been done correctly.
Are frames and sills included in window cleaning?
Many window cleaners include a light wash of frames and sills as standard, especially when using a water-fed pole system. However, this is not guaranteed, so it should be confirmed before booking.
A deep uPVC clean is different from a normal window clean. If frames are stained, green, oxidised or heavily soiled, the cleaner may quote separately for more detailed restoration work.
How much does inside window cleaning cost?
Inside window cleaning is often charged at £2 to £5 per pane, or as part of an inside-and-outside package. For a normal home, inside and outside cleaning may cost 1.5 to 2.5 times the outside-only price.
Internal work takes longer because the cleaner has to protect floors, work around furniture and detail the glass by hand. High stairwell windows, large bi-folds and glass balustrades may increase the price.
How much does conservatory window cleaning cost?
Conservatory side windows may add £15 to £50 to a normal clean, depending on size. A conservatory roof clean usually costs more, often around £40 to £150 or higher for large or heavily soiled roofs.
The price depends on access, roof material, algae build-up, roof bars and whether the quote includes frames, finials, gutters and doors. Always check whether the cleaner is quoting for the sides only or the full conservatory.
Is it cheaper to wash your own windows?
It can be cheaper to wash ground-floor windows yourself if you already have suitable tools. A squeegee, applicator, bucket and microfibre cloths may be enough for simple internal or low-level glass.
The saving becomes less attractive when upper windows, roof lights, awkward access or safety risks are involved. Professional cleaners have purified water systems, poles, insurance and experience, which can make the cost worthwhile for full-property cleaning.
Do window cleaners charge more in London?
Window cleaning prices are often higher in London and parts of the South East because of labour costs, parking restrictions, congestion and travel time. A job that is quick in a small town may take longer in a dense urban area.
That does not mean every London quote is expensive or every northern quote is cheap. Access, property size, frequency and competition in the local area still matter.
What is the cheapest way to get windows cleaned?
The cheapest long-term option is usually to book regular outside cleaning every four to eight weeks. Regular work keeps the windows manageable and allows the cleaner to fit the property into an efficient route.
You can also reduce cost by being clear about access, grouping bookings with neighbours and avoiding last-minute one-off cleans. However, choosing solely on the lowest price can backfire if the service is unreliable or incomplete.
Can window cleaners remove paint, cement or render marks?
Some window cleaners can remove light paint specks or residue, but this is not normally included in a standard window wash. Cement, render, plaster and hard deposits can scratch glass if removed incorrectly.
If your windows are dirty after building work, tell the cleaner before booking. They may need specialist blades, chemicals or restoration methods, and the price will usually be higher than a normal maintenance clean.
How long does it take to wash windows?
A regular outside clean on a typical three-bed house may take around 15 to 30 minutes, depending on access and the number of windows. Larger homes, first cleans and inside-and-outside jobs take longer.
Time is not always the best way to judge value. A professional using the right equipment may work quickly because they have an efficient system, but the quote still needs to cover travel, setup, insurance and business costs.
Are water-fed poles better than traditional window cleaning?
Water-fed poles are very effective for regular outside cleaning because they allow upper windows, frames and sills to be cleaned safely from the ground. The purified water dries naturally, so no wiping is needed.
Traditional squeegee cleaning is still useful for internal windows, shopfronts and detailed finishing. The best method depends on the property, access and type of glass rather than one method always being better than the other.
