Flat Rate Pricing
Flat rate pricing involves quoting a fixed price for the entire job, regardless of the exact measurements.
Examples:
- Small driveway: £250
- Medium patio: £300
- Full house exterior: £800 – £1,200+
This method is based on experience and estimation rather than precise calculations.
Per Square Metre Pricing
Per square metre pricing involves measuring the surface and applying a rate:
Total Area (m²) × Price per m² = Final Cost
Typical UK premium rates:
- Standard professional: £3 – £5 per m²
- Premium services: £5 – £7.50+ per m²
Example:
- 75 m² driveway × £6.50 = £487.50
Side-by-Side Comparison
| Factor | Flat Rate Pricing | Per Square Metre Pricing |
|---|---|---|
| Ease of use | Very simple | Requires measuring |
| Accuracy | Moderate | Very high |
| Profit consistency | Variable | Stable |
| Customer clarity | High | Moderate |
| Best for | Small jobs | Large jobs |
| Premium pricing suitability | Limited | Excellent |
| Scalability | Low | High |
How Pricing Works in the Premium UK Market
In the UK, contractors operating at the higher end typically favour per square metre pricing because it aligns with:
- Accurate cost calculation
- Fair pricing based on workload
- Strong profit margins
However, flat rate pricing is still used for:
- Marketing offers
- Minimum charges
- Simple, repeat jobs
A hybrid model combining both is often the most effective approach.

How Professionals Set Flat Rates
Flat rates are usually based on:
- Average job time
- Typical labour costs
- Expected material usage
- Experience from previous jobs
Example pricing structure:
| Job Type | Flat Rate |
|---|---|
| Small driveway | £200 – £300 |
| Medium driveway | £300 – £450 |
| Large driveway | £450 – £650 |

Clients prefer a simple, all-inclusive price.
3. Effective for Marketing
“Driveways from £250” is easy to advertise.
Disadvantages of Flat Rate Pricing
1. High Risk of Underpricing
If the job is larger or dirtier than expected, profits drop.
2. Limited Flexibility
Flat pricing does not adjust for:
- Surface size
- Heavy contamination
- Difficult access
3. Not Ideal for Premium Work
High-end services require more detailed costing.

How It Works in Practice
Measure each area and apply a rate:
| Surface | Size | Rate | Total |
|---|---|---|---|
| Driveway | 70 m² | £6/m² | £420 |
| Patio | 40 m² | £5.50/m² | £220 |

Advantages of Per m² Pricing
1. Precision
You charge exactly for the work required.
2. Strong Profit Control
Large jobs are priced correctly, avoiding losses.
3. Ideal for Premium Services
Higher rates reflect:
- Specialist treatments
- Additional labour
- Advanced equipment
Disadvantages of Per m² Pricing
1. Slower Quoting Process
Requires measuring and calculations.
2. Customer Education Needed
Some clients may not understand pricing per m².
3. Requires Accurate Rates
Incorrect pricing per m² can still lead to losses.
Premium Pricing Perspective
At the higher end of the market, per square metre pricing becomes the preferred method because it supports:
- Detailed service breakdowns
- Transparent pricing
- Consistent profit margins
Premium services often include:
- Chemical pre-treatment
- Biocide application
- Sealing and protection
- Detailed finishing work
These can justify rates of:
- £5 – £7.50+ per m²
Real-World Comparison Example
Scenario:
- 90 m² driveway
- Heavy moss and oil stains
Flat Rate Quote:
- £550 – £700
Per m² Quote:
- 90 m² × £6.50 = £585
-
- 30% for heavy contamination = £760.50
The per m² method ensures all additional work is properly priced.
Hybrid Pricing Model (Recommended Approach)
Most experienced contractors combine both methods.
Example System:
- Minimum charge: £150
- Then: £5–£7.50 per m²
This ensures:
- Small jobs remain profitable
- Larger jobs are accurately priced
Profit Margin Comparison
Flat Rate Pricing
| Scenario | Result |
|---|---|
| Easy job | High profit |
| Difficult job | Low profit |
Per m² Pricing
| Scenario | Result |
|---|---|
| Small job | Predictable |
| Large job | Consistent profit |
Per square metre pricing provides more reliable financial outcomes.
Labour Considerations
Labour is one of the biggest cost factors in pressure washing.
Typical premium rates:
- £50 – £100 per hour for skilled teams
Time estimates:
| Job Type | Time Required |
|---|---|
| Small driveway | 1–2 hours |
| Medium patio | 2–4 hours |
| Full exterior | 5–12 hours |
Per m² pricing ensures labour time is properly reflected in the price.
Incorporating Add-On Services
Additional services can significantly increase job value.
| Service | Cost |
|---|---|
| Biocide treatment | £50 – £150 |
| Re-sanding | £40 – £100 |
| Sealing | £150 – £400+ |
| Oil stain removal | £50 – £200 |
Per square metre pricing makes it easier to integrate these into quotes.
Seasonal Pricing Impact
Demand for pressure washing services varies throughout the year.
| Season | Demand | Pricing |
|---|---|---|
| Spring | High | Increased rates |
| Summer | Very high | Premium pricing |
| Autumn | Moderate | Stable |
| Winter | Low | Competitive pricing |
During peak seasons, contractors can confidently charge higher rates.
