PAT Testing Regulations in the UK
What the law actually requires, in plain English, and where the "annual test" idea really comes from.
The laws that actually apply
Four pieces of legislation and guidance do the real work here. None of them says "PAT test annually".
Electricity at Work Regulations 1989
This is the central one. Regulation 4(2) requires that electrical systems are maintained, so far as is reasonably practicable, to prevent danger. It is a goal-setting duty: the law tells you the outcome required, not the method. Portable appliances form part of that system.
Health and Safety at Work etc. Act 1974
Sets the general duty on employers to ensure the health and safety of employees and others affected by the work, so far as is reasonably practicable. Faulty electrical equipment is squarely within that duty.
Provision and Use of Work Equipment Regulations 1998 (PUWER)
Requires work equipment to be maintained in an efficient state, in efficient working order and in good repair, and that maintenance logs are kept up to date where they exist.
IET Code of Practice for In-service Inspection and Testing of Electrical Equipment
Not law, but the recognised industry standard that explains how to meet the legal duties. It sets out the combination of user checks, formal visual inspection and combined inspection and testing, and gives suggested initial frequencies by equipment type and environment. This is the document competent testers work to, and it is what we follow.
Where "once a year" comes from
Not from legislation. It comes from a mix of the IET Code's suggested initial intervals, insurer requirements, and habit. The Health and Safety Executive has actively pushed back on blanket annual testing, pointing out that over-testing low-risk equipment wastes money without improving safety. A desktop monitor that never moves is not the same risk as a site power tool.
Sensible testing intervals
These are typical starting points based on the IET Code's approach. They are a guide, not a rule, and should be adjusted as you build up a record of pass and fail results.
| Equipment and environment | Formal visual | Inspection & test |
|---|---|---|
| IT and stationary equipment in a low-risk office | 2 years | Up to 5 years |
| Movable equipment, kettles, extension leads (office) | 1 year | 2 years |
| Handheld equipment in an office or shop | 1 year | 1 to 2 years |
| Kitchen and catering equipment | 6 months | 1 year |
| Equipment in schools and nurseries | 1 year | 1 year |
| Hire, event and production equipment | before each issue | 1 year or less |
| Handheld tools on construction sites | 1 month | 3 months |
Landlords
Two separate duties get confused. Fixed wiring in privately rented homes in England is covered by the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, which require an inspection of the fixed installation at least every five years and a report for tenants. That is an EICR, not PAT testing.
Appliances you supply to tenants, such as a cooker, washing machine, kettle or lamp, sit outside those regulations but remain your responsibility under general safety duties and the Homes (Fitness for Human Habitation) Act 2018. Testing between tenancies is the simple, defensible approach, and it is what most agents now expect. Requirements have also been tightening for social landlords, with in-service inspection and testing duties extended to new tenancies from November 2025 and existing tenancies from May 2026.

What happens if you do not do it
The realistic risks are not usually prosecution. They are an insurer declining a claim because you could not show equipment was maintained, a failed inspection, or a tenancy or contract dispute where you have no records. Prosecution does happen where someone is injured and no maintenance regime existed at all.
What good documentation looks like
A defensible record is more than a sticker. You want an itemised register of every appliance with a unique identifier, the test date, the results, the name of the person who tested it and their competence, plus the next review date. That is what we issue as standard: a PDF certificate with a full itemised report, emailed the same day.
Is PAT testing a legal requirement in the UK?
No law names PAT testing, and no law sets a fixed testing interval. What the law requires is that electrical equipment is maintained in a safe condition. Regulation 4(2) of the Electricity at Work Regulations 1989 requires that electrical systems be maintained, so far as is reasonably practicable, to prevent danger. Inspection and testing is the recognised way to show you have met that duty.
How often does the law say I must test?
It does not give a figure. The Health and Safety Executive is explicit that there is no legal requirement for annual testing, and it warns against over-testing low-risk equipment. Frequency should be based on the type of equipment and the environment it is used in, reviewed over time as you build a history of results.
Who is responsible?
The duty holder: employers, the self-employed, and anyone in control of premises. That includes landlords for equipment they supply, and it cannot be delegated away by hiring a contractor. You remain responsible for making sure the work is done and the records exist.
