What should you charge?
The base-and-modifier method from the manual, as a calculator. Pick the house, the frequency and the add-ons — it prices the visit and shows what the customer is worth over time.
How it prices: windows, frames and sills included every visit; frequency and first-clean premiums follow Chapters 10–11 of The Window Cleaning Works. Treat the output as a starting band, not gospel — the manual shows you how to gather your own 15–30 local price points before you commit.
Pricing questions, answered plainly
How much should I charge for window cleaning 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+. Price to your local market: gather 15–30 local price points before you set your number.
How much extra should a first clean cost?
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 one-off window cleans 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 round worth per customer?
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.
