Window cleaning costs: what to budget

Regular window cleaning is one of the most overlooked aspects of home maintenance — easy to defer until glass becomes noticeably grimy, but simple to organise once a reliable local cleaner has been found. For many homeowners the question of cost comes up when moving to a new property, when establishing a cleaning routine for the first time, or when windows have been neglected long enough that a one-off clean is needed before starting a regular round. Access difficulty, property size, and whether inside cleaning is required all affect what you should expect to pay.

Key points

• Typical UK window cleaning costs range from £5–£15 per visit for a small terraced house to £15–£40+ for a larger detached property (indicative UK costs, last reviewed 2026-05-11).
• Most window cleaners charge a higher rate for a first clean — often 1.5× to 2× the regular price — because heavily soiled glass and frames take significantly longer to clean.
• Water-fed pole (WFP) systems using purified water are now the dominant method in the UK domestic market and are suitable for most properties up to four storeys without requiring a ladder.
• Conservatory roof cleaning is almost always a separate service, typically costing an additional £40–£100 depending on size and access method.
• Window cleaners operating as sole traders below the VAT registration threshold do not charge VAT; check before hiring if you need a VAT receipt for rental or tax purposes.

What affects window cleaning costs?

Number and size of windows The most direct cost driver. A two-bedroom terraced house typically has 8–12 windows; a four-bedroom detached home may have 20–30 or more. Large bay windows, bifold doors, and floor-to-ceiling glazing take longer to clean and often attract a higher price.

Property height and access Ground and first-floor windows are easily reached by a water-fed pole. Windows at second storey and above require an extending pole or specialist access equipment. Some cleaners will not take on work above a certain height and may decline the job or price it significantly higher.

First-clean premium Windows that have not been cleaned for several months — or years — often carry mineral deposits, hard water staining, or bird lime that requires additional time and sometimes specialist products to shift. Most cleaners charge 1.5× to 2× their regular round rate for a first clean.

Frequency A regular four-weekly or six-weekly round costs less per visit than one-off or occasional cleans. The more consistently windows are maintained, the less work each visit involves and the more efficiently the cleaner can plan their round.

Location Prices are higher in London, the South East, and major cities. Rural areas can also see higher prices where fewer cleaners serve a larger geographic area.

Additional services Frame and sill wiping is sometimes included and sometimes charged extra. Gutters, fascias, soffits, and conservatory roofs are almost always separate services priced on top of the standard window clean.

Traditional cleaning vs water-fed pole: what is the difference?

Most professional domestic window cleaners in the UK now use WFP as their primary method. A reputable cleaner will advise which approach they use and explain the finish to expect.

What to ask before hiring a window cleaner

• What is the cleaning frequency — every 4, 6, or 8 weeks?
• Is there a higher first-clean charge, and how much is it?
• What is included — glass only, or frames, sills, and doors too?
• Do you hold public liability insurance, and for what level? (£2 million is standard for domestic work)
• How do you notify me before arriving — text message, an app, or no advance notice?
• How do you prefer payment — bank transfer, direct debit app, or cash?
• Do you clean in wet weather? (WFP cleaners often do; traditional cleaners usually do not)
• What is your policy if I need to postpone a visit?
• Are you a sole trader or limited company, and are you VAT-registered?

Window cleaning homeowner checklist

Before and on the day of a clean:

• Clear obstacles close to windows — plant pots, garden furniture, or ornaments on windowsills
  
• Move items from outside windowsills that could be displaced or damaged by the pole or water
  
• Ensure rear garden gate and side access are unlocked before the cleaner arrives
  
• Close any windows left ajar so water does not enter the property
  
• Check cleaned windows within 24 hours and notify the cleaner promptly if any panes have been missed
  
• Keep the cleaner's contact number saved for scheduling queries or skipped visits
  
• Confirm payment method in advance — many cleaners now use GoCardless or similar for direct debit collection
  

When to get professional help

Most window cleaning is a routine domestic service. However, always use a professional rather than attempting the work yourself when:

• Windows are above the first floor and cannot be safely reached from the ground
• Glass has significant mineral deposits, cement splatter, or paint contamination requiring specialist restoration cleaning
• A leasehold flat or shared building requires a contractor with appropriate insurance and a block cleaning arrangement

Never attempt to clean windows above ground floor from a domestic ladder without correct training and equipment. The Work at Height Regulations 2005 set out the legal requirements for contractors working at height; the same physical risks apply to homeowners.

Frequently asked questions

How often should windows be professionally cleaned?

Most residential window cleaners recommend a four-weekly or six-weekly cycle. Four weeks tends to keep windows consistently clear; six weeks is often sufficient in lower-pollution or rural areas. Annual or twice-yearly cleans are better than nothing, but windows remain dirty for long periods in between and a first-clean premium will usually apply each time a cleaner returns after a gap.

What is the difference between traditional and water-fed pole window cleaning?

Traditional cleaning uses a squeegee and cloth, often from a ladder. Water-fed pole (WFP) cleaning pumps purified water through a brush on an extendable pole, rinsing the glass without soap. WFP is now the dominant domestic method in the UK because it reduces the need for ladders and allows safe access to upper storeys without specialist equipment.

Do window cleaners clean the inside of windows?

Most domestic round cleaners clean the outside only as their regular service. Internal cleaning is usually offered as a one-off or add-on service at a higher price, as it requires access to every room and takes significantly longer. Confirm whether inside cleaning is included when requesting a quote if you want both surfaces cleaned.

Do I need to be home when the window cleaner visits?

For exterior-only cleaning, you do not usually need to be present. Most cleaners work around the outside of the property independently. If the cleaner needs access to the rear garden through a locked gate, make sure arrangements are agreed in advance. Inside cleaning will require someone to be home throughout the visit.

How do I find a reliable local window cleaner?

Word of mouth from neighbours is often the most reliable starting point, particularly if a cleaner already serves your street. Local community groups and noticeboards are also useful. Always ask for proof of public liability insurance before agreeing to a regular round, and check whether the cleaner already operates in your area — round efficiency often results in better pricing for nearby homes.
