Starting or running a mobile Portable Appliance Testing (PAT) business requires a clear understanding of pricing structures. One of the most common questions new technicians and business owners ask is how much they should charge per appliance. Setting the right price is crucial because if you set it too high, you risk losing clients to competitors; if you set it too low, you may struggle to cover operational costs like equipment calibration, travel, and insurance.

Understanding industry standards helps you build a profitable, sustainable model while remaining competitive in the market. In this guide, we will break down the average charges per appliance, key factors that influence pricing, and alternative pricing models for mobile PAT testing businesses.

The Standard Per-Item Pricing Breakdown

In the UK, the average charge per appliance typically ranges between £0.75 and £2.00 for standard commercial environments. However, these figures vary depending on the total volume of appliances tested at a single location. Mobile PAT testing providers generally implement a tiered pricing structure where the rate per item decreases as the number of appliances increases.

Here is a general breakdown of per-appliance pricing based on volume:

• 1 to 50 Appliances: £1.50 – £3.00 per item (often subject to a minimum call-out fee).
• 51 to 500 Appliances: £1.00 – £1.50 per item.
• 501 to 1,000 Appliances: £0.80 – £1.10 per item.
• 1,000+ Appliances: £0.50 – £0.80 per item.

Because travelling to a job site incurs fixed time and fuel costs, most mobile PAT testers charge a minimum call-out fee ranging from £40 to £70. This ensures that smaller jobs—such as inspecting a single DJ setup or a small salon—remain financially viable for the business owner.

Key Factors Influencing Your Rates

No two PAT testing jobs are identical, and pricing should reflect the specific requirements of each assignment. When calculating your per-item rate, you must evaluate several operational and environmental variables:

• Location and Travel Distance: Mobile PAT businesses operating in major metropolitan areas like London often charge higher rates due to congestion charges, parking fees, and higher overall operating costs.
• Accessibility of Equipment: Testing standard office desktop computers is relatively quick. In contrast, testing appliances in commercial kitchens, industrial workshops, or high-level construction sites requires significantly more time and effort.
• Out-of-Hours Testing: Schools, offices, and retail stores often require testing during evenings or weekends to avoid operational downtime. It is standard practice to charge a 25% to 50% premium for out-of-hours service.
• Compliance Documentation: Providing detailed test certificates, fail reports, and itemized register logs adds administrative time, which should be factored into your baseline pricing.

Proper technical training allows technicians to assess these factors accurately and price jobs effectively. Taking a comprehensive pat testing course helps professionals master both electrical safety standards and practical business administration, ensuring they remain compliant while running a profitable service.

Alternative Pricing Models for PAT Testers

While charging a flat rate per appliance is the most common industry standard, alternative pricing structures may better suit certain client types or business setups.

1. Fixed Minimum Fee + Per-Item Rate: This hybrid approach charges a flat fee covering up to a set number of appliances (for example, £50 for up to 30 items), with a reduced rate applied for every additional appliance tested beyond that initial threshold.
2. Hourly or Daily Rates: For complex environments such as manufacturing plants or server rooms—where access is restricted and tests take longer—charging by the hour (£30 – £50/hour) or offering a full-day rate (£250 – £400/day) provides greater financial security.
3. Annual Service Contracts: Offering package deals or long-term maintenance contracts for schools, hotels, or corporate offices provides recurring revenue and allows you to offer slight discounts on per-appliance costs.

Choosing the right structure depends heavily on your target client base, location, and daily capacity.

How to Calculate Your Ideal Profit Margin

To set pricing that ensures steady profits, you need to calculate your true cost per job. You must account for direct expenses such as fuel, vehicle maintenance, label stickers, replacement fuses, and replacement plugs. Additionally, don't forget fixed overheads like tester calibration, insurance, marketing, and software management tools.

For instance, if a technician tests an average of 20 to 30 items per hour in a standard office setting, charging £1.20 per item yields an hourly income of £24 to £36 before expenses. By optimizing workflow, using pass/fail barcode scanners, and streamlining report generation, mobile PAT testers can increase their hourly output to 40+ items, substantially raising overall profitability.

Final Thoughts

Pricing mobile PAT testing services requires a balance between competitive market rates and healthy profit margins. While charging around £1.00 to £1.50 per appliance is a dependable baseline for medium-volume jobs, adapting your structure with minimum call-out fees and premiums for complex settings ensures your mobile business remains viable and thriving over the long term.
