The short answer
No. PAT testing is not a legal requirement in its own right, and there is no legal duty to have appliances tested every year. The Electricity at Work Regulations 1989 require electrical systems and equipment to be maintained so as to prevent danger, so far as is reasonably practicable. They do not specify what that maintenance must consist of, who should carry it out, or how often. The Health and Safety Executive says so directly: the Regulations "don't make inspection or testing of electrical appliances a legal requirement, nor do they make it a legal requirement to undertake this annually".
The annual PAT test is therefore a convention, not a statute. What the law requires is maintenance proportionate to risk — and in many low-risk workplaces, HSE's guidance says that means visual checks rather than testing.
What the law actually requires
The Electricity at Work Regulations 1989 apply in England, Wales and Scotland, and have done since 1 April 1990. Regulation 4(2) requires that, as may be necessary to prevent danger, all systems are maintained so as to prevent danger so far as is reasonably practicable. The duties fall on employers, the self-employed and employees in relation to work activities.
Two things follow from that wording. First, the duty is qualified: "reasonably practicable" means balancing the level of risk against the money, time and trouble needed to control it, and action is not required where the cost would be grossly disproportionate to the risk. Second, the Regulations are about outcomes, not methods. They do not mention portable appliance testing at all. "PAT testing" is an industry term for a combined inspection and test; it is not a phrase that appears in the legislation.
For work equipment there is a parallel duty. The Provision and Use of Work Equipment Regulations 1998 require every employer to ensure work equipment is maintained in an efficient state, in efficient working order and in good repair.
The Management of Health and Safety at Work Regulations 1999 require a risk assessment, and where there are five or more employees the significant findings must be recorded in writing. That assessment is what determines how much inspection and testing your equipment needs.
Jurisdiction matters here. Northern Ireland has its own Electricity at Work Regulations, made in 1991, rather than the 1989 Regulations. And the work-based Regulations govern work activities: they do not regulate a tenant's use of a kettle in their own home. Rented housing is covered by housing law, which I come to below.
Where the annual test came from
If the law does not demand an annual test, why does almost everyone believe it does?
HSE is blunt about it. Its guidance for low-risk environments opens by calling the annual test "a myth": "It's a myth that all portable electrical appliances in a low-risk environment, such as an office, need to have a portable appliance test (PAT) every year."
The belief survives because several things push in the same direction. Insurers write PAT intervals into policies. Letting agents and managing agents put annual testing into management agreements. Franchise systems standardise it across sites. Testing contractors quote annual cycles because that is how the work has long been sold. None of those is statute, but each is a contractual or commercial requirement that a dutyholder may still have to meet.
There is also a genuine piece of industry guidance that gets mistaken for law: the IET's Code of Practice for In-service Inspection and Testing of Electrical Equipment. It sets out how to inspect and test, and how to decide intervals — useful, authoritative, and not legislation.
What HSE recommends instead
HSE's recommended maintenance plan has three levels, and only the third involves a tester.
User checks. The person using the equipment looks it over before and during use for damage to the cable, damage to the plug, taped joints, a cable grip that is not holding the sheath, contamination, cracked casing, loose parts or signs of overheating. Faults are reported and the item is taken out of use immediately.
Formal visual inspection. A competent person carries out a more systematic inspection at regular intervals, including opening the plug, where it is not moulded, to check the fuse, the terminals and the cord grip. HSE says most potentially dangerous faults can be found this way, and that you do not need to be an electrician to do it.
Combined inspection and test. Some faults — loss of earth integrity, deteriorated insulation, contamination — cannot be seen. Those need a test, carried out by someone with a greater degree of competence.
The intervals are where the annual assumption does most damage. HSE's table gives suggested initial frequencies by equipment type and environment. Construction-site 230V equipment: user checks daily, formal visual inspection weekly, combined test before first use and then monthly. Office IT that is rarely moved: visual inspection every two to four years, and no test at all if it is double insulated. Earthed Class I equipment such as kettles: visual inspection every six to twelve months, test every one to two years.
Those figures are starting points, not rules. HSE calls them suggested initial frequencies, and says the dutyholder must decide, based on the conditions and on what previous checks have found. Where faults are rare, intervals can be extended; where they are common, they should be shortened.
Records and labels are optional too. There is no legal requirement to keep maintenance logs for portable equipment, and no legal requirement to label equipment that has been inspected or tested. Both are useful management tools, and HSE recommends them, but neither is a legal duty. If you do label, HSE says the person carrying out the test should not decide when the next test is due — that is your decision, on a risk-assessment basis.
None of that is difficult, but it does require a judgement about your own equipment and how it is used. Our PAT testing service starts from that judgement rather than from a fixed annual schedule.
What this means for landlords
This is where the confusion does the most commercial damage, because two different legal regimes get mixed together.
For landlords in England, the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 require every electrical installation in the property to be inspected and tested by a qualified person at intervals of no more than five years, with a report supplied to tenants and to the council on request. Note the word "installation". The duty covers the fixed wiring, consumer unit, sockets and similar — not the appliances plugged into them. The Regulations define "electrical equipment" separately, as fixtures, fittings and appliances that are not part of the installation, and the installation duties are framed around installations.
The landlord's repairing covenant points the same way. Section 11 of the Landlord and Tenant Act 1985 requires the landlord to keep in repair and proper working order the installations for the supply of electricity, "but not other fixtures, fittings and appliances for making use of the supply".
So a private landlord has no statutory duty to PAT test a tenant's own kettle, and no statutory annual cycle for appliances they supply. That does not mean appliances are ignored. The Housing Health and Safety Rating System, which councils use to grade hazards in a home, includes electrical hazards, and a council can require action where an appliance or installation presents a serious risk.
Social landlords are now in a different position. The 2020 Regulations were amended in 2025 to extend them to registered providers, in force in stages from 1 November 2025 with the remaining provisions from 1 May 2026, and those duties include electrical equipment provided under the tenancy: each item must be checked by a qualified person at intervals of no more than five years. Even here, the statute does not prescribe an annual PAT. "Check" is defined as such visual inspection or testing (or both) as the qualified person considers necessary to determine whether the equipment is safe for continued use. The five-year maximum is the legal backstop; the method is a matter of competent judgement.
Where a tenancy agreement or an insurer requires annual PAT testing, that is a contractual term. It may be perfectly sensible — but it should be described as a contractual requirement, not as "the law".
If you let property, the essential guide to PAT testing for landlords covers the tenancy side in more detail, and what PAT testing actually tests explains what a combined inspection and test involves.
What to do this week
- List the portable equipment you control, and where it is used. Wet, dusty, outdoor and heavy-use environments raise the risk; a dry office lowers it.
- Record the risk assessment that sets your intervals, including why you chose them. With five or more employees, that record is a legal requirement.
- Decide who does each level: user checks, formal visual inspection, combined inspection and test. Visual inspection can be done by a trained employee; testing needs greater competence.
- Set intervals from HSE's table as a starting point, then adjust them using your own fault history.
- Stop using anything that fails, label it, and have it repaired by a competent person before it returns to service.
- Review the plan when faults cluster, when equipment or premises change, or when the environment changes.
- If a client, insurer or tenant asks for annual testing, check whether it is a legal duty or a contractual one — and say which.
