How to price window cleaning jobs

Start from the going rate in your area

Before you set a single price, know what customers around you already expect to pay. The 2026 cost guide from MyJobQuote lists an exterior clean of a terraced house with 8 to 10 windows at £20 to £35 taking 20 to 40 minutes, a semi detached house with 10 to 14 windows at £20 to £40 taking 30 to 45 minutes, and a detached house with 15 to 20 or more windows at £35 to £60 taking 45 to 90 minutes.

HowMuchShouldItCost gives a national 2026 average of £25 for an exterior clean of a three bed house, with a low of £15 and a high of £40, and a regular monthly clean of the same house at £12 to £30 with an average of £20. The same guide reports London averaging £30, about 24 percent above the national figure, and Belfast averaging £20, about 13 percent below. Those regional gaps are real money on a round of 200 houses, so use local figures rather than a national average.

Hourly rates are the other anchor. The Pure Seal Services pricing guide puts the general range at £25 to £40 per hour, with £35 to £45 in London and the South East, £25 to £35 in the Midlands and South West, and £20 to £30 in the North, Scotland and Wales. Whatever you charge per house, check that it adds up to at least your target hourly rate once travel between jobs is included.

Per window versus per visit pricing

Per window pricing is easy to explain and is the method most beginners are taught. Pure Seal Services lists small windows at £1.00 to £1.50, medium windows at £1.50 to £2.50, large bay windows at £3.00 to £5.00, skylights and roof windows at £3.00 to £6.00 and conservatory panels at £1.00 to £1.50 each. Count the panes, apply the rates, and you have a quote.

The problem is that per window quotes ignore how long it takes to get to the job and set up. A house with six windows in a street where you clean ten others is far more profitable than a house with six windows on its own twenty minutes away. That is why most established cleaners quote a per visit price, built from the window count but adjusted for access, travel and how many neighbours are already on the round.

A sensible compromise is to use per window rates as your internal calculator and only ever tell the customer the visit price. Pure Seal suggests using round figures, noting that £25 looks cleaner and more deliberate than £24.67. The customer hears one number, and your notes hold the breakdown.

Uplifts for first cleans, access and travel

A first clean nearly always takes longer than a maintenance clean because dirt has built up on the frames and sills. MyJobQuote reports one off or deep cleans at £40 to £90 depending on condition, and HowMuchShouldItCost gives a one off deep clean at £40 to £120 with an average of £70, against £12 to £30 for the same house on a regular monthly cycle. Pure Seal recommends adding 50 to 100 percent to the standard rate for a builders clean on a new property and about 15 percent for a one off deep clean.

Hard to reach windows justify a separate price. HowMuchShouldItCost lists hard to reach window cleaning at £40 to £150 with an average of £75, and skylight or roof window cleaning at £10 to £40 per unit. If a window needs a longer pole, a ladder or access from a neighbour's garden, price that time in rather than absorbing it.

Travel is the cost that quietly eats a round. Pure Seal advises adding £5 to £10 when significant travel of 20 minutes or more is involved. A better long term fix is to fill streets rather than scatter customers, because a tight round lets you clean more houses per hour at the same price.

Add on services that raise the ticket

Frames and sills are the easiest upsell. HowMuchShouldItCost gives frame and sill cleaning at £20 to £70 with an average of £40, and Pure Seal quotes it as a £5 to £10 add on to a standard visit. Many cleaners simply include frames in the regular price and charge more overall.

Conservatory roofs are a bigger job. MyJobQuote lists a conservatory including the glass roof at £25 to £30 extra, or £45 to £50 with frame and gutter work, while HowMuchShouldItCost reports a standalone conservatory roof clean at £100 to £250 with an average of £150. The gap reflects whether the roof is done as part of a regular visit or as a separate deep clean.

Gutter clearing is the other common add on. MyJobQuote puts it at £20 to £40 added to a window clean, and HowMuchShouldItCost gives £50 to £120 as a standalone job with an average of £80. Inside windows are usually priced at around 50 percent of the exterior cost according to Pure Seal, and MyJobQuote notes that interiors typically need cleaning only every 3 to 6 months, so they suit an occasional extra rather than the regular cycle.

Set the cycle and price the frequency

MyJobQuote reports that most UK homes have exterior windows cleaned every 4 to 8 weeks, with regular contracts every 4 to 6 weeks offering better value than one off bookings. Pure Seal describes a common discount structure of 10 percent off for a 4 weekly clean, 5 percent off for 6 weekly, no discount at 8 weekly and a 15 percent uplift for one offs. The logic is simple: a 4 weekly customer is easier to keep clean and is on your round more often, so you can afford to charge slightly less per visit.

Whatever cycle you agree, count it from the day you actually cleaned, not the day you planned to. Weather and holidays push visits around, and a customer on a 6 week cycle who was last cleaned on the 3rd should be due on the 14th of the following month, not on a fixed calendar slot. A round book that records the real clean date and rolls the next due date forward from it saves the arithmetic. RoundTally works this way, with each customer on a cycle of four, six, eight or any number of weeks counted from the last completed clean, and unpaid visits collected into an owed list.

Finally, review prices once a year. Costs for fuel, water fed pole resin and insurance rise, and customers on a round for years often sit far below current rates. A small annual increase across the whole round is easier to explain than a large jump after five years.

Worked example for a three bed semi

Take a semi detached house with 12 windows, two of them medium and the rest small, plus a small front porch. At Pure Seal's per window rates that is 10 small windows at £1.25 for £12.50, two medium at £2 for £4, and £1.50 for the porch glass, giving £18. Round that to £20 for a 4 weekly regular clean, which sits inside MyJobQuote's £20 to £40 range for a semi.

For the first visit, apply an uplift. If the frames are grimy, a 50 percent uplift takes the first clean to £30. If the customer wants the conservatory roof done as well, add £25 to £30 on that first visit and agree whether it repeats every few months.

If the same house is on its own on the far side of town, add £5 to £10 for travel and quote £25 to £30 for the regular clean, or decline politely until you have more customers nearby. A price that is right for the street is wrong for the outlier, and most pricing mistakes on a round come from treating them the same.
