What is a PAT testing certificate?
A PAT testing certificate is a document that records the results of portable appliance testing carried out on electrical equipment. It confirms which appliances were tested, whether they passed or failed, and the date of the next recommended test. It’s the standard proof that a business or landlord has met their electrical safety obligations.
PAT testing is routine across UK workplaces, rental properties, and public venues. Electricians and PAT testing engineers carry out the inspections, which involve a visual check and electrical tests using a dedicated PAT tester. The certificate serves as the formal record of their findings.
While the law doesn’t prescribe PAT testing by name, the Electricity at Work Regulations 1989 require that electrical equipment is maintained in a safe condition. A PAT testing certificate is the accepted way to prove compliance.

- Tester Details: Name, qualifications, and company of the person carrying out the testing
