Pressure washing is one of the most versatile property maintenance services — from sprucing up a garden patio to restoring a commercial car park. But if you’re running (or starting) a pressure washing business in the UK, one of the first questions you’ll face is:

👉 How do I bill for pressure washing, and what should I charge in £?

Pricing pressure washing jobs can feel tricky at first. You want to stay competitive, but you also need to cover your costs and make a healthy profit. This guide will walk you through how to bill for pressure washing in the UK, step by step.

We’ll cover:

• The different billing methods UK contractors use.

• The factors that affect pricing.

• Average price ranges in pounds (£).

• Example breakdowns for domestic and commercial jobs.

• Sample invoice layouts.

By the end, you’ll know exactly how to structure your billing system and confidently quote clients.

---

1. Common Billing Methods in the UK

In the UK, most pressure washing companies use one of four billing approaches. Each has its pros and cons depending on the type of job.

👉 Tip: Many UK contractors combine methods. For example, you might charge per square metre for patios but use an hourly rate for tricky, irregular cleaning jobs.

---

2. Factors That Affect UK Pressure Washing Prices

Before you send a quote, you need to consider more than just the area to be cleaned.

Here are the main factors that influence billing in the UK:

---

3. Average UK Pressure Washing Rates

Let’s look at typical UK market prices. (Note: These vary by region — London and the South East are usually higher than the Midlands or North.)

Residential Pressure Washing Prices

Commercial Pressure Washing Prices

---

4. Example Billing Calculations

Here’s how different billing methods might look for the same job: cleaning a 50m² block-paved driveway in Manchester.

👉 Notice how similar these totals are. The main difference is how you communicate the price to the customer.

---

5. Building a Pricing Formula

A smart way to ensure you’re always profitable is to build a simple formula:

Total Price = Base Call-Out Fee + (Rate × Area) + Extras

Example:

• Base Call-Out Fee: £30 (covers travel, setup, insurance).

• Rate: £3/m².

• Area: 40m² driveway.

• Extras: Oil stain treatment (£25).

Calculation: £30 + (£3 × 40) + £25 = £175.

This way, you can quickly and consistently quote jobs while covering costs.

---

6. Optional Extras You Can Bill For

Upselling extras is a great way to increase revenue per job. Many UK contractors charge separately for:

Offering these as add-ons not only boosts revenue but also positions you as a full-service provider.

---

7. Commercial Contracts – How to Bill

When dealing with commercial clients (retail parks, housing associations, industrial sites), billing often shifts from one-off pricing to contractual billing.

Two common approaches in the UK are:

👉 With commercial clients, you’ll usually invoice monthly and may need to agree 30-day payment terms.

---

8. Example Invoice Template (UK Format)

Here’s what a basic pressure washing invoice might look like:

---

9. Tips for Billing Success in the UK

1. Be Transparent – Break down the job (e.g., area, extras, call-out fee) so clients understand value.

2. Research Competitors – Check local rates to avoid undercharging or overpricing.

3. Set Minimum Job Fees – Many contractors set a minimum charge (£60–£80) to avoid wasting time on very small jobs.

4. Offer Discounts for Repeat Work – Encourage regular cleaning (e.g., “10% off if booked twice yearly”).

5. Use Software/Apps – Tools like QuickBooks, Xero, or Joist can help you send professional invoices.

6. Get Deposits for Large Jobs – Especially with commercial clients, request 20–30% upfront.

7. Always Include Terms – State payment due dates, late fees, and accepted payment methods.

10. Regional Pricing Differences in the UK

Pressure washing prices vary depending on where you are in the UK.

👉 If you work in an area with lower rates, consider adding extras (sealing, sanding, chemical treatments) to boost margins.

---

11. Residential vs Commercial Billing – Key Differences

While the techniques are similar, billing for residential and commercial clients requires different approaches.

👉 For commercial work, always factor in admin time (RAMS, health & safety docs, site inductions).

---

12. The Importance of Minimum Charges

Without a minimum charge, you risk wasting time on small jobs. For example, if a customer asks you to clean a 5m² path and you charge £3/m², that’s only £15 — not worth the trip.

Most UK contractors set a minimum fee of £60–£80, which covers:

• Travel

• Set-up time

• Equipment wear and tear

• Labour

👉 Clients usually understand this once you explain the cost of travel and setup.

---

13. How to Quote Professionally

Your quote sets the tone for your business. A clear, detailed quote shows professionalism and builds trust.

What to Include in a Quote

1. Business details (logo, contact info).

2. Client details (name, address, phone/email).

3. Job description (surface, area, condition).

4. Pricing breakdown (rate × area, extras, VAT if applicable).

5. Total price (bold and clear).

6. Validity period (e.g., “Valid for 30 days”).

7. Payment terms (deposit, balance due).

👉 Consider using quoting software (e.g., Joist, Quotient, or even Microsoft Word templates) to make your quotes polished and consistent.

---

14. VAT and Tax Considerations in the UK

If your business turnover exceeds £90,000/year (2025 threshold), you must register for VAT. This will affect how you bill clients.

• Residential clients: VAT makes you appear more expensive.

• Commercial clients: VAT is usually recoverable, so less of an issue.

👉 Even if under the threshold, always keep records of:

• Income & expenses.

• Mileage and fuel costs.

• Equipment purchases.

This helps with self-assessment tax returns. Many small operators use accounting software like QuickBooks, Xero, or FreeAgent.

---

15. Handling Disputes and Late Payments

Unfortunately, not every client pays on time. To protect your business:

Tips for Preventing Issues

• Always issue written quotes and get approval before starting work.

• Use clear payment terms (e.g., “Payment due within 14 days of invoice”).

• For larger jobs, take deposits (20–30%).

Late Payment Strategy

1. Polite reminder (day 15).

2. Second reminder (day 21).

3. Final notice with late fee (day 30+).

UK law allows you to charge interest on late payments under the Late Payment of Commercial Debts Act.

👉 Most homeowners pay quickly, but commercial clients sometimes need chasing.

---

16. Growing Your Pressure Washing Business Through Smart Billing

Billing isn’t just about getting paid — it’s a tool for growth.

Ways Billing Can Help You Scale

• Tiered pricing: Offer Bronze, Silver, Gold packages (basic clean vs clean + seal).

• Subscription services: Offer quarterly patio cleans at a discounted annual rate.

• Commercial contracts: Lock in predictable monthly income.

• Upselling extras: Use your invoice to suggest additional services.

👉 By making billing structured, professional, and transparent, you encourage repeat clients, referrals, and bigger contracts.

17. Final Thoughts

Billing for pressure washing in the UK doesn’t have to be complicated. The key is to pick a consistent method, factor in your costs, and communicate clearly with your clients.

• For domestic jobs, per square metre or flat-rate pricing works best.

• For commercial jobs, contracts and monthly billing provide steady income.

• Always cover extras, travel, and setup costs in your quotes.

If you build a clear billing system with transparent rates in pounds (£), your clients will appreciate the professionalism — and your business will grow sustainably.

Pressure washing (or jet washing, as it’s often called in the UK) is one of the most effective ways to bring a driveway back to life. Whether you’ve got block paving in Surrey, tarmac in Manchester, or concrete slabs in Glasgow, pressure washing can strip away years of dirt, moss, algae, and oil stains.

But one of the first questions homeowners ask is:

“How long will it take to pressure wash my driveway?”

The answer depends on several factors — driveway size, material, equipment used, water supply, and whether extra treatments are needed.

This guide breaks down the typical cleaning times for different types of driveways in the UK, with real-world examples, tables, and cost implications.

---

1. Why Cleaning Time Matters

Understanding how long it takes to pressure wash a driveway helps in three ways:

---

2. Average Time Ranges for UK Driveways

Here’s a quick overview of typical times based on size:

👉 These estimates include setup, cleaning, and tidying up but may vary depending on driveway material and condition.

---

3. Key Factors That Affect Cleaning Time

3.1 Driveway Material

Different surfaces react differently to pressure washing:

3.2 Size of Driveway

The larger the driveway, the more time required. Most UK domestic driveways fall between 30–60 m².

3.3 Equipment Used

3.4 Condition of Driveway

• Light dirt/algae → Quicker, usually just surface wash.

• Heavy moss, weeds, oil stains → Much slower, requires multiple passes and chemical treatment.

3.5 Extras (After-Clean Tasks)

• Re-sanding block paving joints → Adds 30–60 minutes.

• Applying sealant → Adds 2–3 hours (plus drying time).

---

4. Time Estimates by Driveway Type

Here’s a more detailed breakdown of average times per material for UK homes:

---

5. DIY vs Professional Cleaning Times

Takeaway: If time matters, hiring a professional can halve the duration.

---

6. Real-World Examples (UK Case Studies)

Case 1: Small Block Paving in Birmingham

• Size: 25 m²

• Condition: Moss in joints, light oil stain near garage

• Equipment: Kärcher K5 electric washer

• Time Taken: 3 hours (plus 45 mins re-sanding)

Case 2: Medium Tarmac Driveway in Manchester

• Size: 40 m²

• Condition: Algae growth, no stains

• Equipment: Contractor petrol washer + surface cleaner

• Time Taken: 2.5 hours (no aftercare required)

Case 3: Large Concrete Driveway in Glasgow

• Size: 85 m²

• Condition: Heavy moss, black spots, oil patches

• Equipment: Professional jet washer + chemical pre-treatment

• Time Taken: 6.5 hours including stain treatment

---

7. How Weather Affects Time

In the UK, weather plays a role in how long jobs take:

---

8. How UK Water Supply Affects Time

Unlike some countries, most UK homes have good mains pressure (2–4 bar). Still, water supply can affect cleaning:

💡 UK Water Cost: Average £2.30 per m³ (1,000 L).

• A medium driveway uses ~500 L → Cost to homeowner: £1.15.

---

9. Time vs Cost Relationship

Since many UK companies price based on time, knowing cleaning duration helps predict costs.

---

10. Tips to Speed Up the Process

1. Clear the driveway first (cars, bins, pots).

2. Sweep heavy debris before washing.

3. Treat weeds/moss a few days before.

4. Use a surface cleaner instead of a lance nozzle.

5. Hire professionals if time is more valuable than cost.

---

11. Comparison with Other Household Chores

For perspective:

---

12. Frequently Asked Questions

Q: Can I pressure wash my driveway in one hour?

• Only if it’s very small (<15 m²) and lightly soiled.

Q: Does block paving always take longer?

• Yes, because moss grows in joints and sanding is required afterwards.

Q: Will a DIY Kärcher take all day?

• For medium driveways, yes — expect 5–6 hours.

Q: Do professionals always work faster?

• Almost always, because their machines deliver 3–4x more water flow.

Q: What’s the longest it can take?

• Very large, moss-heavy driveways can take a full day (8–10 hours).

---

13. Summary Table (UK Driveway Cleaning Times)

21. Conclusion

So, how many hours does it take to pressure wash a driveway in the UK?

• Small driveways: 1.5–3 hours

• Medium driveways: 2.5–4 hours

• Large driveways: 4–6+ hours

• Extra large/shared: Full day

DIY with an electric jet washer can double the time, while professional petrol-powered machines and surface cleaners cut the duration significantly.

The key takeaway: expect anywhere from 2–6 hours for most UK driveways, depending on size, material, and equipment.

If you value time, hiring a professional not only delivers faster results but also ensures the driveway is properly treated and restored.

Pressure washing is one of the most effective ways to clean exterior surfaces such as driveways, siding, decks, patios, and roofs. But one question often arises from homeowners and business clients alike:

“Do pressure washing companies use the customer’s water supply, or do they bring their own?”

This is a fair question because water is the primary resource required for pressure washing. The answer, however, depends on several factors including company policy, project size, equipment type, and client preferences.

This article explores the topic in depth—covering how water is supplied, how much is typically used, what alternatives exist, and what customers should expect when hiring a pressure washing company.

---

1. Why Water Supply Matters in Pressure Washing

Unlike vacuuming or mopping, pressure washing relies heavily on water volume and pressure. The machine amplifies the force of water to blast away dirt, mold, mildew, and stains.

Without a reliable water source, pressure washing simply isn’t possible. Here are the main reasons water supply is so critical:

---

2. The Common Practice: Using the Customer’s Water

In the majority of residential and small commercial jobs, pressure washing companies use the customer’s water supply. This is done by connecting a hose from the client’s outdoor spigot to the pressure washer.

Why This Is Standard

• Convenience: Outdoor water taps provide immediate access without requiring water transport.

• Efficiency: Eliminates the need for filling, hauling, and refilling tanks.

• Cost Savings: Keeps operating costs lower for the contractor, which can mean lower prices for the client.

• Sufficient Supply: Most residential water systems provide 40–60 PSI (pounds per square inch) of water pressure, which is adequate for pressure washers.

Customer Concerns

Some homeowners initially worry:

• “Will this run up my water bill?”

• “Is my water pressure strong enough?”

• “What if I don’t want them to use my water?”

We’ll answer these below.

---

3. How Much Water Does Pressure Washing Use?

Water usage depends on several factors: machine type, nozzle size, surface area, and duration of cleaning.

Typical Usage

Cost Impact to the Customer

Most municipalities in the U.S. charge between $0.002 – $0.005 per gallon of water.

Let’s calculate:

• Average driveway wash uses 500 gallons.

• At $0.003 per gallon, that’s $1.50 in water costs.

So while customers do technically pay for the water if their supply is used, the actual cost is minimal compared to the service fee.

---

4. When Do Companies Bring Their Own Water?

Some pressure washing companies do bring water tanks—particularly for commercial or specialized jobs.

Common Scenarios:

Tank Sizes Used

The downside is cost. Transporting water requires special equipment and higher fuel consumption. Companies that bring their own water often charge more.

---

5. How to Know Which Method a Company Uses

If you’re a customer wondering whether a contractor will use your water or theirs, here’s how to find out:

• Check the quote or contract: Many companies specify this upfront.

• Ask directly: A reputable company will be transparent.

• Look at their equipment: Trailer-mounted tanks are a sign they bring their own supply.

• Consider the job type: For most residential jobs, expect them to use your spigot.

---

6. Pros and Cons of Using Customer’s Water vs. Company’s Water

---

7. Addressing Common Customer Concerns

Concern 1: “Will it spike my water bill?”

No, the increase is negligible. Even at the high end (1,000 gallons), the added cost is around $3–5—far less than the value of the service.

Concern 2: “What if my water pressure is low?”

Most residential systems are adequate. If pressure is too low, companies can:

• Use booster pumps.

• Bring their own water tank.

• Adjust equipment to work with limited supply.

Concern 3: “What if I don’t want my water used?”

Customers can request the company to supply their own water, but this usually raises the service price.

---

8. Industry Standards and Regulations

In many regions, pressure washing companies must follow water usage regulations to prevent waste.

• EPA Guidelines: Wastewater from pressure washing must not enter storm drains untreated.

• Local Restrictions: Some cities impose drought-related rules limiting outdoor water use.

• Best Practices: Contractors are encouraged to use water efficiently and recycle when possible.

Companies that bring their own water often also bring reclamation systems to collect and reuse water.

---

9. Environmental Considerations

Some customers wonder if using their water is eco-friendly. The truth is:

• Using customer’s water eliminates the fuel needed to haul large tanks, which can actually reduce the carbon footprint.

• Using company’s water can lead to better efficiency if combined with recycling systems.

Either way, responsible wastewater management matters more than the source.

---

10. Practical Tips for Customers

If you’re hiring a pressure washing company, here are things you can do regarding water supply:

1. Locate your outdoor spigots before the crew arrives.

2. Clear access to water connections (remove hoses, obstacles).

3. Check for leaks in your spigot beforehand.

4. Ask about water usage during the estimate process.

5. Review your water bill afterward for peace of mind.

---

11. Case Study Examples

Residential Driveway Cleaning

• Customer Water Used: 400 gallons over 2 hours.

• Extra Cost to Customer: $1.20 in water.

• Total Service Fee: $250.

Result: Customer saved money by allowing contractor to use their water.

Commercial Storefront Cleaning

• Company Water Supply: 500-gallon tank on trailer.

• Reason: No outdoor water access at retail location.

• Added Cost: $75 water transport fee.

• Total Service Fee: $850.

Result: More expensive, but necessary due to site conditions.

---

12. Frequently Asked Questions

Q: What if my water is on a well system?

• Contractors can still use your well water, but they’ll ask about flow rate. Low-output wells may not be ideal.

Q: Can pressure washing be done without water?

• No. Water is the medium that carries dirt away. “Dry” methods like sandblasting exist but are very different services.

Q: Do all companies have tanks?

• Not all. Many small, local companies rely entirely on customer water. Larger commercial operators often have tank setups.

Q: Can I ask for a discount if they use my water?

• Usually, no. It’s already built into the pricing. Bringing their own water typically costs more, so using yours is already the cheaper default.

---

13. Sample Communication Script

Here’s an example of how a contractor might answer a customer asking this question:

Customer: “Do you use my water or bring your own?”
Contractor: “For residential jobs like yours, we typically connect to your outdoor spigot. Don’t worry—the total water used is small, usually costing just a dollar or two on your bill. If you’d prefer we bring our own supply, we can, but there is an additional fee to cover transport and tank setup.”

---

14. Comparison Table: Water Usage in Household Activities vs. Pressure Washing

This shows that pressure washing water usage is not extreme compared to everyday tasks.

---

16. How Water Pressure Affects the Results

Not all water supplies are created equal. Residential homes usually have a pressure range of 40–60 PSI, while commercial buildings may have much higher. This can impact how efficiently the pressure washer performs.

Takeaway: If your home water pressure is unusually low, a contractor may recommend alternative setups.

---

17. Water Filtration and Quality Concerns

Some customers ask: “Does the quality of my water affect the cleaning?”

• Hard Water: Can leave mineral deposits, but this is rarely an issue for exterior surfaces.

• Well Water with Sediment: May clog filters or nozzles if not properly managed.

• Filtered/Softened Water: Not necessary but can help in delicate applications (e.g., washing windows or vehicles).

Many professional contractors use inline filters on their hoses to ensure debris doesn’t damage equipment.

---

18. Efficiency Strategies to Reduce Water Use

Reputable pressure washing companies take pride in minimizing waste. Here are common efficiency methods:

These techniques benefit both the contractor (lower operating costs) and the environment.

---

19. Customer Negotiation Tips

If you’re hiring a pressure washing service and want clarity about water usage, here’s how you can handle it:

• Ask before booking: “Do you use my water supply or bring your own?”

• Request a breakdown: If they bring their own, ask if there’s a transport fee.

• Negotiate efficiency: Some companies may offer discounts if you pre-rinse surfaces or provide easier access.

• Bundle services: Combining driveway, deck, and siding cleaning in one visit makes the most efficient use of water.

💡 Pro Tip: Customers worried about their water bill can ask the company to estimate gallons used, then check with their utility provider for the exact cost per gallon.

---

20. Future Trends in Pressure Washing Water Supply

The industry is evolving, and water management is becoming more innovative. Here are trends shaping the future:

This shows that the debate over “whose water is used” may shift in the future, as efficiency and sustainability continue to rise in importance.

21. Conclusion

So, do pressure washing companies use customers’ water?

• Yes, in most residential jobs—because it’s convenient, cost-effective, and sufficient.

• Sometimes no, in commercial or remote jobs—when they bring tanks for independence and volume.

Ultimately, the choice depends on the company’s setup and the client’s needs. For homeowners, the cost of providing water is negligible, and using your supply usually means a lower service fee. For businesses or special cases, paying for a company to haul water may be the only option.

The most important step is clear communication upfront. Asking your contractor about water usage ensures there are no surprises on the day of service.

Pressure washing is one of the fastest and most effective ways to restore a patio’s appearance. But blasting away dirt with water alone often won’t give the best results — and in some cases, it can even damage the surface or leave behind stubborn stains.

The secret to a great clean is what you put on the patio beforehand. Applying the right pre-treatment not only helps loosen grime but also protects the surface, controls moss and algae regrowth, and reduces the water pressure you’ll need to use.

In this guide, we’ll cover:

• Why pre-treatment matters

• Different types of pre-washing solutions

• How to choose the right cleaner for your patio type

• How to apply pre-treatments effectively

• Safety and environmental considerations

• Stain-specific pre-treatments

• Cost comparisons for DIY vs. commercial products

---

1. Why Pre-Treatment Before Pressure Washing Matters

Many people go straight to pressure washing, but skipping the pre-treatment step can lead to:

• Needing higher PSI (which risks surface damage)

• Missed stains that require extra passes

• Incomplete removal of moss/algae roots (leading to fast regrowth)

• Wasting time and water

Pre-treatment benefits:

• Loosens dirt and biological growth before water hits

• Allows lower pressure cleaning, safer for pavers or natural stone

• Reduces streaking and patchy cleaning results

• Kills spores and prevents immediate regrowth

---

2. Types of Pre-Treatment Solutions

Here are the main categories of products you might put on your patio before pressure washing:

---

3. Choosing the Right Cleaner for Your Patio Material

Not all patio surfaces can tolerate the same chemicals. Here’s a quick reference:

---

4. Step-by-Step Pre-Treatment Process

Step 1: Clear the Patio

• Remove furniture, pots, and loose items

• Sweep away leaves, loose dirt, and debris

Step 2: Wet Surrounding Plants

• Rinse any nearby grass, flowers, or shrubs to protect from overspray

Step 3: Mix or Prepare Solution

• Follow manufacturer dilution instructions exactly

Step 4: Apply Evenly

• Use a pump sprayer for even coverage

• Work in sections for large patios

Step 5: Allow Dwell Time

• Leave solution to sit for 10–30 minutes (longer for moss/algae killers)

• Do not let it dry out — mist lightly if needed

Step 6: Begin Pressure Washing

• Start at a low PSI and adjust only as necessary

---

5. Common Pre-Treatment Chemicals & What They Do

---

6. Safety Precautions

Personal Safety:

• Wear gloves, goggles, and old clothes

• Avoid breathing in spray mist

• Never mix chemicals unless directed by manufacturer

Property & Environmental Safety:

• Protect plants and soil with water rinse or tarp

• Avoid letting runoff enter drains unless safe

• Always check product’s biodegradability rating

---

10. Mistakes to Avoid

---

11. Environmentally Friendly Pre-Treatment Options

• Vinegar & water mix — good for light algae

• Baking soda paste — spot treat stains

• Plant-based surfactants — commercial “green” patio cleaners

• Oxygen bleach — kills moss/algae without chlorine smell

---

12. Timing Your Pre-Treatment

• For light dirt/algae: Apply 15–30 mins before pressure washing

• For heavy moss/lichen: Apply 1–3 days before for full kill effect

• Avoid hot sunny days where solution dries too fast

• Best results in mild, dry weather

---

13. Tools for Applying Pre-Treatment

---

14. Preparing a Weed-Free Base Before Washing

If weeds are growing between pavers:

• Apply weed killer 1–2 weeks before washing

• Pull large weeds manually

• Pressure washing alone may scatter seeds rather than kill them

---

15. Commercial Pre-Treatment Brands (UK Examples)

---

16. Preparing Different Patio Types

Block Paving:

• Weed killer + moss killer

• Degreaser for oil spots

Natural Stone:

• pH-neutral cleaner

• Avoid acids unless for rust

Concrete Slab:

• Moss killer

• Degreaser for BBQ/oil

---

17. Preventing Future Growth

After pressure washing:

• Apply residual biocide to deter algae/moss regrowth

• Re-sand block paving joints with kiln-dried sand

• Seal surface if appropriate

20. Final Checklist Before Pressure Washing

✅ Remove loose debris & furniture
✅ Protect plants with water/tarp
✅ Select correct cleaner for surface & stains
✅ Apply evenly with sprayer or watering can
✅ Allow correct dwell time
✅ Keep surface damp during dwell
✅ Rinse lightly if required before pressure washing

---

Bottom line:
What you put on your patio before pressure washing makes all the difference. Whether it’s a mild detergent for a quick spruce-up or a professional-grade biocide for deep moss removal, pre-treating is the key to a safe, effective, and long-lasting clean.

17. Verdict

Yes — you can pressure wash your own house in the UK, but:

• Keep pressure low.

• Use the right nozzle and detergent.

• Don’t attempt high or delicate areas yourself.

If in doubt — especially with multi-storey homes — hiring a pro could save you both money and headaches.
