Is PAT Testing a Legal Requirement?
No law says “PAT test”, but the duty to keep equipment safe is legal — and PAT is how most people meet it. Here is the real position.

The short answer
There is no law that specifically requires “PAT testing”. However, the Electricity at Work Regulations 1989 and health-and-safety law place a legal duty on employers, the self-employed and landlords to keep electrical equipment safe and maintained. PAT testing is the standard, well-recognised way to demonstrate you have met that duty — so in practice it is how most businesses and landlords stay compliant.
This one causes a lot of confusion. People hear “PAT testing is the law” and also “PAT testing is not a legal requirement” — and both are sort of true. Here is what the regulations actually say.
What the law requires
The legal duty is to keep electrical equipment in a safe condition — it does not prescribe PAT testing by name, nor fixed intervals. The Electricity at Work Regulations 1989 require that equipment is maintained to prevent danger. For employers and landlords, that duty is real and enforceable; PAT is simply the accepted method of meeting and documenting it.
Who really needs it
In practice you should be PAT testing if you are:
- An employer or self-employed person with equipment used at work.
- A landlord providing appliances with a let property.
- Running a public-facing business (shop, salon, café, office).
- Required to by your insurer or a licensing condition.
Frequently asked questions
- How often should equipment be tested?
- It is risk-based, not fixed by law. Low-risk office IT might be every one to four years; handheld tools and site equipment, far more frequently. See our guide on how often office equipment should be PAT tested.
