Commercial window cleaning is bought differently. Nobody at a facilities company watches you work from the kitchen window. They read documents, and the published prices are thin: Checkatrade lists commercial jobs at £100 to £500, MyJobQuote prices a small shopfront at £5 to £15 a visit and a large building at £100 to £500 and up, and no major guide publishes a commercial day rate at all, as of our check on 4 September 2026. Thin published pricing means the buyer relies on proof instead, which is where the marketing happens.
What a commercial buyer checks before price
Public liability at a level worth stating, employers’ liability, which is a legal requirement with £5m minimum once you have staff, a risk assessment and method statement they can file, and how you handle height. HSE guidance says work at height should be avoided where reasonably practicable, so a firm that leads with water fed pole methods and the Work at Height Regulations is speaking the buyer’s language before anyone mentions money. Put all of it on one commercial page in plain text, with your company number.
The commercial page, done in an evening
One page titled commercial window cleaning in your town. On it: the sectors you clean, shopfronts, offices, schools, new builds. Your insurance and method statement, offered as a download. Frequency options with honest from-prices per visit for a shopfront, because the £5 to £15 published range gives you cover to be concrete. Two photos of real commercial jobs. That single page outperforms a brochure because procurement searches, and engines quote pages, not PDFs.
Winning the work without a tender
Most small commercial contracts never reach a portal. They change hands when the current cleaner lets someone down. The practical route: a short letter or email to the twenty nearest shopfronts and offices naming your day on that street, your price per visit, and your insurance, then the same again each quarter. Reliability is the pitch, and the proof is your residential round working the same street every fortnight.
Price it like a contract, not a favour
Trade guidance prices commercial work per job after a site visit, not per window from a table. Access, frequency and invoicing terms move the number more than glass area. Quote annually where you can, thirteen four weekly visits reads smaller as one monthly figure, and put a review date in writing so the price rises without a renegotiation from zero.
Common questions
How much does commercial window cleaning cost in the UK?
Published figures are thin. Checkatrade lists £100 to £500 per commercial job and MyJobQuote £5 to £15 a visit for a small shopfront up to £500 and more for large buildings, read 4 September 2026. Most real commercial work is priced after a site visit.
What insurance does a commercial window cleaner need?
Public liability at a stated level, and employers’ liability, legally required at £5m minimum once you employ anyone. Commercial buyers also commonly expect a risk assessment and method statement covering how work at height is handled.
How do window cleaners win commercial contracts?
Mostly by being visibly reliable when the incumbent fails. A one page commercial offer with insurance, methods and honest from-prices, put in front of nearby premises each quarter, positions you as the obvious replacement.
