How much does PAT testing cost in Stevenage & Welwyn?

PAT testing in Stevenage & Welwyn starts from 89p per appliance. Sites with fewer than 150 appliances carry a £70 service charge to cover travel and set-up. Sites with 151 or more appliances pay the per-appliance rate only, with no additional call-out fee. Volume rates of 89p per appliance apply for estates over 10,000 appliances.

How often is PAT testing required?

There is no fixed legal interval for PAT testing. The IET Code of Practice recommends a risk-based approach: office equipment is typically tested every 2–4 years, while equipment used in harsher environments such as construction sites or kitchens may need annual testing. Your employer or landlord is responsible for determining a suitable frequency based on the type of equipment and how it is used.

What does PAT testing include?

PAT testing includes a visual inspection of the appliance, cable, and plug, followed by electrical tests using a calibrated PAT tester. Tests typically cover earth continuity, insulation resistance, and where applicable, lead polarity and earth leakage. Each appliance receives a pass or fail label and is recorded in a detailed test register. A certificate is issued on completion.
