British jet washing prices are published in square metres, and this calculator asks for square metres too. If your job sheet is in square feet, divide by 10.76: £2.00–£5.25 per square metre is £0.19–£0.49 per square foot.
How the calculator works
- Surface sets the band. Driveway, house siding, decking or patio, and fence each carry their own band. Picking one fills in the area that surface typically covers.
- Area scales it, and the minimum catches small jobs. Below roughly 15 square metres of driveway the £50 minimum sets the price rather than the area.
- Soft wash and soil move the quote. A soft wash adds about 22%. Heavy soil moves the quote up the range rather than adding an invented cost.
- Your region. Rates are adjusted by a regional labour-cost index. London runs about £40 above the rest on a 46 m² driveway, the calculator’s starting job.
- Your economics. “Your costs and margin” turns area into hours, adds chemicals, machine wear and travel, and shows what the market price leaves you before VAT.
Typical UK jet washing rates in 2026

Concrete, asphalt and block paving sit at the lower end; block paving reaches £5.25. Crews bill £40–£80 an hour, £62 typical. Minimum charge £50. All figures exclude VAT.
Where the British numbers are thin, said plainly
Nobody publishes a British minimum charge for this trade. The £50 comes from one franchise operator’s own floor and a marketplace average. A small driveway at £250 is the practical lower bound for a whole job.
Two of the four bands are not British readings. No British source prices a whole house wash or a fence by area. The house siding band is the British hourly rate, £40–£80, over the area a crew washes in an hour on a wall. The fence band is the American whole-job figure carried across on the ratio between the two markets’ driveway rates.
Sealing is a separate sale, not a markup. Sealing runs £6–£10 per square metre, kiln-dried sand £2.50 and polymeric £4.50. The trade prices these as their own lines because the material stays on the job, so there is no resale margin to add.
What moves the price
- Block paving over concrete. Jointing sand comes out with the dirt and has to go back in. That is the sand line above, not a bigger wash rate.
- Moss and algae. A biocide adds about 15% to the base rate.
- Two-storey walls. Ladders or a longer wand. Quote the top of the siding band.
- Oil stains. £20–£50 as its own line.
Worked example
A 186 m² house wash with heavy algae on one wall — about 2,000 sq ft. Siding takes the vertical norm, so that is 3.1 hours on site. The sample fills your pay at £23 an hour. The typical quote lands at £195 (range £160–£235) against a cost near £126 — labour, £13 of chemicals, machine wear, travel and 15% overhead — which leaves £69 a visit, a 36% margin before VAT. The “Fill with sample data” button loads this exact job.
What this calculator does not price
Gutters and fascias are sold per linear metre, not per area. Roofs have published prices — £4–£6 per square metre standard, £900–£1,200 for a detached house — but no published hours, and a calculator that turns area into hours cannot honestly price a surface whose hours nobody publishes. Quote those from your own records.
