Window cleaning prices, priced properly.
Whether you're getting quotes or setting them, this is the base-and-modifier method working window cleaners use: house type, area, frequency, add-ons.
How it prices: Base price by house type, multiplied for your area and the visit frequency, plus add-ons — with a first-clean premium because first cleans carry heavier soiling. It's the method from Chapters 10–11 of The Window Cleaning Works. Treat the output as a starting band, not gospel — gather 15–30 local price points before you commit to a number.
What window cleaning costs in the UK in 2026
A three-bed semi on a regular four-weekly round is typically £18–£25 per visit for exterior windows, frames and sills, with £22 a common anchor. Terraces and flats sit lower, large detached houses £28–£35 and up. One-off cleans price 25–50% above the round rate, and a first clean usually carries a 50–100% premium because it takes far longer than a maintained job.
Prices move with postcode more than with glass. The same house can be £18 in one town and £26 twenty minutes away — which is why the calculator asks about your area, and why anyone pricing seriously should gather local price points before settling on a number.
If you're the one holding the squeegee
The number that matters isn't the visit price — it's the round. At £22 every four weeks, one kept customer is worth about £286 a year, roughly £2,000 over a typical seven-year customer lifetime. Underprice by £4 a house across an 80-house round and you've given away £4,000 a year for the privilege of being busy.
The full pricing chapter — gathering 15–30 local price points, anchoring, raising prices without losing the round — is in The Window Cleaning Works, the £47 manual this calculator comes from.
Pricing questions, answered plainly
How much does window cleaning cost in the UK?
A typical three-bed semi-detached house is £18–£25 for exterior windows, frames and sills on a four-weekly round, with £22 a common anchor in 2026. Terraces sit a little lower, large detached houses £28–£35 or more.
How much should a window cleaner charge for a first clean?
First cleans carry heavier soiling and take longer, so most operators charge a 50–100% premium on the regular price, agreed with the customer in advance.
Should a one-off window clean cost more than a regular round?
Yes. A one-off clean is typically priced 25–50% above the regular four-weekly rate, because there is no recurring relationship to justify the lower price.
What is a window cleaning customer worth per year?
At £22 every four weeks — roughly thirteen cleans a year — one kept customer is worth about £286 a year, and around £2,000 over a typical seven-year customer lifetime.
