Use this free calculator to estimate the monthly cost of a commercial cleaning contract in the UK. Enter your floor area, site type, and cleaning frequency for an indicative 2026 price range. It is a guide only, before VAT — for an exact fixed-monthly figure, book a free site survey.
How the estimate is worked out
The calculator applies typical 2026 UK per-visit rates for each site type to your floor area and cleaning frequency, then adds a London premium where relevant. Warehouses are cleaned to a lighter touch per square metre than offices; healthcare and food sites are higher because of frequency and compliance. Small sites are subject to a practical monthly minimum. The result is a range, because the real figure depends on your exact specification — which we confirm at a free survey.

Frequently Asked Questions
How accurate is the cleaning cost calculator?
It gives an indicative monthly range based on 2026 UK market rates for recurring commercial cleaning — floor area, site type, frequency, and whether the site is in London. Real quotes depend on the exact specification, access, consumables, and contract term, so we confirm the figure with a free site survey. Prices shown are before 20% VAT.
Does the estimate include VAT?
No. Commercial cleaning is standard-rated, so 20% VAT is added on top of the figures shown. The calculator displays the ex-VAT monthly range; your quote will show VAT separately.
Why is cleaning priced monthly and not by the hour?
Recurring commercial cleaning is delivered to a defined scope on a fixed monthly fee, not by the hour, so you pay for a clean building rather than hours on site. Optus Glean UK bills one fixed monthly fee by Direct Debit with an annual indexed review — no hourly invoicing and no surprise call-out charges.
What makes the price go up or down?
The biggest drivers are floor area, cleaning frequency (days per week), the standard required (healthcare and food sites are higher), and location — London carries roughly a 20–30% premium. The wage floor also matters: the 2026 National Living Wage is £12.71/hour and the Real Living Wage, which many tenders require, is £13.45 (£14.80 in London).
