Frequently Asked Questions
Common questions about commercial pat testing
How long does commercial PAT testing take?
Testing time depends on the number of appliances. We typically test 50–100 appliances per hour. We will give you a precise time estimate when you book.
Do I need PAT testing by law?
While PAT testing itself is not a legal requirement, the Electricity at Work Regulations 1989 require employers to maintain electrical equipment in a safe condition. PAT testing is the recognised method of demonstrating compliance.
What certification do your engineers hold?
Our PAT testing engineers hold City & Guilds 2377 qualifications. Our electricians are NICEIC certified. All engineers are DBS checked for access to sensitive premises.
Can you test outside business hours?
Yes — we offer evening, weekend, and bank holiday appointments to minimise disruption to your business operations.
What happens to failed appliances?
Failed appliances are clearly labelled as unsafe and removed from service. We provide a detailed report and can advise on repair or replacement options.
