Window-cleaning costs swing sharply between jobs. A two-bed terrace with six small windows can cost £25, while a five-bed detached house with bay windows and a conservatory can run past £60. Frequency matters too: a one-off clean costs around 75% more than a regular six-weekly round.

This guide breaks down UK window-cleaning costs by hour, window and job type. You'll also learn what affects the price and how to keep your costs down.

Note: All prices in this guide exclude VAT unless stated otherwise. Most window cleaners fall below the £90,000 VAT registration threshold, so their quotes typically don't include VAT.

What do window cleaners charge per hour in the UK?

Hourly rates for UK window cleaners average £25 an hour. That figure holds fairly steady whether you're comparing quotes in a small town or a major city, though it can flex up for jobs that need specialist access equipment.

Most residential cleaners don't bill by the hour. Hourly pricing is more common for larger one-off jobs, house clearances before a sale or lettings inspection, and properties where the scope isn't clear until the cleaner arrives. 

How much does window cleaning cost per window?

Window cleaning costs around £3 for a standard window, £1.50 for a small pane and £5 for a large or bay window. Per-window pricing is most common for one-off jobs, shopfronts and properties with an unusually high window count.

Sliding patio doors and French doors usually cost more than a single pane. Cleaners may count these as two or three windows, since the glass area and access time are closer to that of multiple standard panes. Skylights and roof windows sit at the upper end too because of their access requirements.

How much does a full window cleaning job cost?

A regular window cleaning visit for a typical UK home costs around £33. Property size affects the price, with terraced homes costing £31, semi-detached homes £33 and detached homes £44.

Window cleaning cost by property type (GBP, excluding VAT)

A first or one-off clean costs around 75% more than a regular visit. This is because frames, sills and neglected glass need far more scrubbing than a maintenance clean.

What affects the cost of window cleaning?

Five factors move the price more than anything else: property size, cleaning frequency, location, window access and what's included beyond the glass.

Location deserves its own breakdown, since the gap between regions is wider than most people expect.

Regional window cleaning cost per visit (GBP, excluding VAT)

Regular customers may pay less than the figures above, particularly when a cleaner has several nearby properties on the same route. That gap comes down to route efficiency. A cleaner doing ten houses on one street spends less travel time per job than on a single call-out.

Residential pricing follows the property-type table above almost exactly, with two common additions: interior cleaning and conservatory work. Interior windows typically add £10 to £30 to a standard exterior-only quote, since most cleaners treat inside and outside as separate services.

Conservatories are also priced separately. A full interior and exterior conservatory clean costs around £248, reflecting the extra glass area and the awkward angles of a sloped roof. Gutter cleaning costs a further £88 on average when added to the same visit.

How much does commercial window cleaning cost?

Commercial rates run higher than residential ones because of scale, access requirements and stricter scheduling around business hours. A small shopfront or office costs around £60 per visit, while a larger commercial building averages £300 per visit.

Commercial window cleaning cost (GBP, excluding VAT)

Commercial cleaners often price contracts per visit rather than per window, since quotes usually follow a site assessment rather than a fixed per-pane rate. Frequency tends to be tighter too, with offices and retail units typically cleaned every two to four weeks, compared with the six-week average for homes.

Why does regular window cleaning matter?

Grime and hard water deposits don't just sit on the surface. Left long enough, mineral deposits can etch permanently into the glass, and grime trapped in frame corners encourages mould and mildew. Clean windows also let in noticeably more natural light, which matters more in the UK than in sunnier climates during the shorter winter months.

There's a practical property angle too. Regular window cleaning is one of the cheapest ways to lift a property's kerb appeal before a property viewing or tenancy start. Clean windows are a relatively simple way to make a property look well maintained.

What window cleaning methods do UK professionals use?

Two methods that dominate the UK market are traditional squeegee cleaning and the water-fed pole system. Traditional cleaning uses a scrim, applicator and squeegee and still works well for ground-floor and easily accessible windows.

Water-fed pole systems have become the modern standard for most residential rounds. They use purified water, either deionised or reverse osmosis, pushed through an extendable pole that can reach up to roughly 20 metres without a ladder. 

For anything higher, cleaners switch to mobile elevated platforms for buildings up to around 60 metres. For genuine high-rise work, they use rope access and abseiling techniques.

The method your cleaner uses doesn't usually change the price on its own. It mainly determines what's physically possible for your property's height and access.

What should I check before hiring a window cleaner in the UK?

A few checks before you book will save you far more hassle than they cost in time. Run through this before agreeing a price with anyone:

• Ask whether they hold public liability insurance
• Check for Federation of Window Cleaners (FWC) or Safety Accredited Membership (SAM) accreditation
• Confirm exactly what's included, such as frames, sills or interior glass
• Get the quote in writing before work starts
• Ask which method they use and whether it suits your property's height
• Read reviews from recent, local customers
• Clarify what happens if something is damaged during the clean

How often should I get my windows cleaned?

Most UK homes are professionally cleaned every six weeks. This interval helps prevent grime from building up while keeping regular cleaning costs manageable.

Commercial properties are cleaned more often, averaging every three weeks, because footfall and street-level dust build up faster around shops and offices. Rural homes can often go around 12 weeks between cleans, as they generally face less traffic pollution.

For most homes, sticking to a regular six-weekly schedule keeps dirt from building up and reduces the need for more intensive cleans.

How can I save money on window-cleaning costs?

The biggest saving usually comes from committing to a regular schedule rather than booking one-off visits. A one-off clean costs around 75% more than a regular round, so repeat bookings can reduce your cost per visit.

The following tactics make a real difference too:

• Book a regular round instead of repeated one-off visits
• Bundle gutter clearing or conservatory cleaning into the same appointment
• Get quotes from at least three local cleaners before choosing one
• Clean easily reachable ground-floor windows yourself between professional visits
• Ask about a discount for signing up to a fixed weekly, monthly or six-weekly plan

Window cleaning in the UK averages £33 a visit or £25 an hour, with property size, frequency and location doing most of the work in moving that number up or down. A regular six-weekly round on a semi-detached house sits right at that average, while one-off cleans and larger properties cost more. Before you book, compare at least two or three quotes and ask each cleaner about their regular-schedule discount.
