Setting the right price for a pressure washing job can feel like threading a needle. Too low and you’ll struggle to cover costs; too high and you’ll scare away customers. This guide walks you through every factor that shapes a fair charge, offers three proven pricing models, and hands you a ready‑to‑use checklist so you can price confidently in any part of the UK.
What Drives a Pressure Washing Quote?
Before you pick a pricing model, understand the variables that push the numbers up or down. Most of these factors are quantifiable, which means you can turn them into a transparent formula for every job.
- Pressure washing is a cleaning method that uses high‑pressure water to strip dirt, grime, and mildew from surfaces such as driveways, decks, and façades. The type of surface (concrete, brick, wood) influences labour time and required detergent.
- Residential pressure washing is a service focused on homes, typically involving driveways, patios, gutters, and siding. Jobs are usually smaller but may need more delicate handling.
- Commercial pressure washing is a service for businesses, covering large façades, parking decks, and industrial equipment. Scale and safety requirements add complexity.
- Surface area - measured in square feet or metres - directly correlates with water usage, detergent amount, and time on site.
- Access and preparation - obstacles, steep slopes, or the need for power‑wash‑ready wiring can add prep time.
- Equipment depreciation - your pump, 50 psi or higher, hoses, and PPE cost money to own and maintain.
- Insurance and licensing - UK regulations require public liability cover and, for certain chemicals, HSE‑approved handling.
Three Pricing Models That Actually Work
Most pressure washers in the UK base their quotes on one of three frameworks. Pick the one that matches your business size and client expectations.
| Model | How it’s calculated | Best for | Typical range (UK) |
|---|---|---|---|
| Per square foot / metre | Base rate × surface area | Standard residential jobs (driveways, patios) | £0.12‑£0.30 per ft² (≈£1.3‑£3.2 per m²) |
| Hourly rate | Hourly fee × total labour hours | Complex commercial sites, variable prep | £45‑£85 per hour |
| Flat‑rate per job | Fixed price based on typical effort | Marketing‑friendly quotes, repeat customers | £120‑£350 for a standard driveway |
Sample Calculations - From Estimate to Invoice
Let’s run through two realistic scenarios so you can see the numbers in action.
Scenario 1 - A 500 ft² residential driveway
- Determine surface area: 500 ft².
- Choose a Square foot pricing is a method that multiplies a per‑ft² rate by the total area to be cleaned. Assume £0.20 per ft² for a standard concrete surface.
- Base charge: 500 ft² × £0.20 = £100.
- Add equipment depreciation (estimated £10 per job) and insurance markup (5 % of base).
- Equipment: +£10 → £110.
- Insurance: 5 % of £100 = £5 → £115 total.
- Final quote: £115, rounded to £120 for simplicity.
Scenario 2 - A 2,500 ft² commercial warehouse façade
- Assess difficulty: high‑traffic area, need for scaffolding.
- Pick an Hourly rate is a pricing model that charges for each hour of labour, useful when job variables are unpredictable. Set your rate at £70 per hour.
- Estimate labour: 6 hours (including set‑up, cleaning, and safety checks).
- Labour cost: 6 × £70 = £420.
- Equipment wear: £25 per large‑scale job.
- Insurance & HSE compliance: £30.
- Total before profit: £475.
- Apply 15 % profit margin: £475 × 1.15 = £546.25 → round to £550.
UK‑Specific Considerations
Pricing in Britain isn’t just about raw costs; regulation and market expectations shape what clients will pay.
- Health and Safety Executive (HSE) guidelines require you to assess slip hazards on wet surfaces. Factor in extra time for signage and barrier placement.
- Water use charges vary by region. In London, water abstraction fees can add £0.02‑£0.05 per litre; in rural Wales they’re lower.
- Environmental rules restrict certain detergents. Opt for biodegradable agents; they may cost 10‑15 % more but can be a selling point.
- VAT is currently 20 %; decide whether to quote inclusive or exclusive. Most residential customers prefer inclusive pricing.
- Seasonality matters. Spring and summer see a 30‑40 % surge in demand, allowing you to raise rates modestly.
Cost Breakdown for a Small Pressure‑Washing Business
Understanding your overhead helps you set a sustainable base rate.
| Expense | Monthly amount |
|---|---|
| Vehicle (van depreciation & insurance) | £250 |
| Equipment loan/maintenance | £120 |
| Public liability insurance | £80 |
| Detergents & consumables | £70 |
| Marketing (online ads, flyers) | £150 |
| Utilities (phone, internet) | £40 |
| Miscellaneous (protective gear, licences) | £60 |
| Total overhead | £770 |
Divide the total by the average number of billable jobs per month (e.g., 20 jobs) to see the minimum profit you need per job: £770 ÷ 20 ≈ £38.5. Add labour, profit, and VAT, and you arrive at a realistic quote range.
Pricing Checklist - Don’t Forget These Items
- Measure the exact surface area (use a laser distance measurer for accuracy).
- Identify the material and any stains that may need special chemicals.
- Check local water abstraction fees and factor them into the estimate.
- Calculate equipment depreciation: (Purchase price ÷ expected lifespan in jobs).
- Include insurance, HSE compliance, and VAT in the final figure.
- Offer a clear breakdown on the invoice - clients appreciate transparency.
- Set a standard profit margin (15‑20 % works for most UK markets).
- Review competitors’ rates in your area to ensure you stay competitive.
Frequently Asked Questions
How do I decide between per‑square‑foot and hourly pricing?
If the job has a clear, measurable surface and few obstacles, square‑foot pricing is simple and transparent. Complex jobs with scaffolding, multiple levels, or unpredictable prep time are better served by an hourly rate, because you can capture the extra labour without constantly revising the quote.
What is a fair profit margin for a pressure‑washing business?
Most small operators aim for a 15‑20 % margin after covering overhead, equipment wear, and insurance. If you’re in a high‑cost region like London, you might push to 25 % to offset higher water fees and insurance premiums.
Do I need a licence to use pressure washers in the UK?
You don't need a specific licence, but you must comply with HSE safety guidelines, hold public liability insurance, and if you use chemicals classified as hazardous, you need the appropriate COSHH assessment. Some local councils also require a waste disposal permit for runoff.
How much water can I legally discharge when pressure washing?
There is no national limit, but many councils set guidelines to protect drainage systems. As a rule of thumb, stay under 10 litres per minute for residential work and use a collection system if you’re near a watercourse.
Should I include VAT in my quote?
If your customers are private homeowners, they usually prefer a VAT‑inclusive price so the final amount is clear. For B2B contracts, it’s common to show the net price and add VAT separately on the invoice.
Armed with these numbers and a solid checklist, you can set fees that cover costs, make a profit, and keep clients happy. Remember, transparency builds trust - show the breakdown, stay within local regulations, and adjust rates as your business grows.
