There is no legislation that specifies mandatory PAT testing frequencies. The legal requirement under the Electricity at Work Regulations 1989 is that electrical equipment is maintained in a safe condition. PAT testing is one way of demonstrating this -- but frequency must be risk-assessed, not assumed.
There is no UK legislation that names 'PAT testing' or sets a mandatory testing frequency for portable appliances. The legal duty comes from the Electricity at Work Regulations 1989, which requires that electrical systems and equipment be constructed, maintained and used in a way that prevents danger, so far as is reasonably practicable. Portable Appliance Testing is simply one recognised method of demonstrating that this duty is being met -- it is not itself a legal requirement.
HSE guidance is explicit that testing frequency should be determined by the type of equipment, how it is used, and the environment it operates in, not applied as a blanket annual cycle. A hand-held hairdryer used occasionally in a resident's room carries a very different risk profile from a mobile hoist or hydraulic bath lift that is moved, plugged and unplugged multiple times a day across different rooms. Treating both the same either over-tests low-risk items or, more concerning, under-tests high-risk ones.
A defensible approach starts with an inventory of all portable and movable electrical equipment, then assigns each item to a risk category based on its construction (Class I versus Class II), how frequently it is moved or handled, and the consequences of failure. High-use mobile equipment such as hoists, portable heaters and equipment used in wet areas typically warrants more frequent inspection and testing than static, rarely-moved office equipment, which may only need occasional visual checks.
A significant proportion of electrical faults in portable equipment are picked up by simple user checks -- looking for damaged plugs, cracked casings, frayed cables or signs of overheating before use -- rather than by formal combined inspection and testing. Embedding a basic visual check into daily use, alongside a less frequent formal PAT cycle for higher-risk items, is a more proportionate and defensible approach than annual testing of everything regardless of risk.
Because there is no fixed legal frequency, the key protection for a care home operator is a written record explaining how the testing schedule was arrived at -- the risk categories used, the intervals set for each, and the date of the last review of that schedule. This documented rationale is what an HSE inspector or insurer will look for, since it shows the duty under the 1989 Regulations has been actively considered rather than assumed to be satisfied by a generic annual PAT contract.
