Portable Appliance Testing (PAT) landlord guidance | August

Portable Appliance Testing (PAT) guidance for landlords

Electrical safety is among the most important responsibilities a UK landlord carries, yet confusion persists around Portable Appliance Testing. Is it legally required? Which appliances need checking, and how often? This guide sets out your PAT obligations, clears up the common misconceptions, and explains how regular testing protects both your tenants and your rental business.

What is PAT testing?

Portable Appliance Testing checks electrical appliances to confirm they are safe to use. Despite the name, "portable" covers any appliance with a plug that connects to the mains, whether it moves about or stays in one place. The process combines a visual inspection with electrical testing, looking for damage, wear and the kind of faults that can cause shocks or fires. A tester, usually an electrician or trained technician, examines the casing, plug, cable and internal components for frayed wires, cracked casings, loose connections and signs of overheating, then measures earth continuity, insulation resistance and polarity. Each appliance gets a pass or fail label showing the test date and when the next check is due. The phrase "PAT testing" is strictly speaking redundant, since the T already stands for testing, but it has become standard industry shorthand.

Is PAT testing a legal requirement for landlords?

PAT testing is not a legal requirement for landlords in England and Wales. It is effectively mandatory in Scotland, and it is commonly required as a condition of an HMO licence anywhere in the UK. What applies everywhere is the underlying duty: a landlord must make sure the electrical appliances they supply are safe, and a PAT certificate is the clearest way to evidence that you have done so. The detail differs by nation.

England and Wales

There is no law that explicitly requires PAT testing in England and Wales, but that does not mean appliance safety is optional. Several pieces of legislation create a duty of care. The Landlord and Tenant Act 1985 requires landlords to keep electrical installations and supplied appliances in repair and proper working order, the Electricity at Work Regulations 1989 and the Health and Safety at Work Act 1974 require electrical equipment to be maintained to prevent danger, and the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 underline landlords' wider electrical safety obligations. Consumer protection law also requires goods supplied with a tenancy to be safe. If an incident involves an appliance you provided, you have to show you took reasonable steps to ensure it was safe, and a PAT certificate is strong documented evidence that you met that duty.

Scotland

PAT testing is a clear requirement for Scottish landlords under the Housing (Scotland) Act 2006 and the Repairing Standard. Since 1 December 2015, private landlords must ensure the portable appliances they provide are tested as part of their electrical safety obligations. In practice this means two related checks at least every five years and at the start of each new tenancy: an Electrical Installation Condition Report on the fixed wiring, and a Portable Appliance Test on landlord-supplied appliances. Failure to comply can lead to enforcement by the First-tier Tribunal for Scotland, including Repairing Standard Enforcement Orders and rent penalties.

Houses in multiple occupation

Wherever the property is, an HMO usually requires PAT testing as a licence condition. Local councils run HMO licensing, and most mandate routine testing of shared appliances, so check your specific licence conditions. Some councils, Newcastle upon Tyne among them, require PAT testing even for standard rentals as a licensing condition, so always verify local requirements alongside the national position.

Which appliances need PAT testing?

PAT testing applies to the electrical appliances you provide as part of the tenancy, meaning any item with a plug the tenant can use. In practice that covers white goods such as washing machines, tumble dryers, dishwashers, fridges, freezers and free-standing cookers; small kitchen appliances like microwaves, kettles and toasters; heating and cooling such as portable heaters, electric blankets and fans; entertainment and technology including televisions and lamps; cleaning equipment such as vacuum and steam cleaners; and any garden equipment you supply, like mowers, hedge trimmers and pressure washers. Extension leads and multi-socket adaptors count too, if you provide them.

Appliances the tenant brings themselves are their own responsibility, and you only need to test items listed in your property inventory as landlord-supplied. If you replace a tenant's broken appliance during the tenancy, though, that replacement becomes yours and needs testing. Built-in equipment wired directly to the fixed installation, such as an immersion heater or a hard-wired electric shower, falls under your EICR rather than PAT, and that distinction matters for your records.

How often should PAT testing be carried out?

There is no single legally prescribed interval. The Health and Safety Executive sets none, because the right frequency depends on the appliance, how heavily it is used and its environment, so the figures below are best practice rather than law. The HSE's own guidance, "Maintaining portable electrical equipment", is a useful reference.

For furnished lets, test before each new tenancy to establish a clean baseline and to be able to demonstrate compliance from day one. For ongoing tenancies, a practical pattern is annual testing for high-use or high-risk items such as kettles, toasters, portable heaters and irons, every two years for standard items like lamps, radios and televisions, and every four years for larger white goods that see less handling. Between formal tests, a quick visual check during routine visits or at changeover catches obvious damage early. HMOs and student lets see heavier use and faster turnover, so often warrant annual testing across the board, and some councils require it. If an appliance shows visible damage, strange noises or a burning smell, test or remove it immediately, whatever the schedule says.

Who can carry out PAT testing?

Anyone competent can carry out PAT testing. In Scotland, landlords can test their own appliances if they have completed appropriate training, such as a course from Landlord Accreditation Scotland, and in England and Wales a landlord with sufficient knowledge can self-test, though professional testing gives stronger evidence of due diligence. For most landlords, a qualified electrician or a certified PAT testing company makes practical sense: they bring the right equipment, current knowledge and insurance, and issue formal certificates. Look for membership of a recognised body such as NICEIC, NAPIT or SELECT in Scotland, and ask to see public liability insurance and qualifications before booking. Professional testing typically costs between £1 and £3 per appliance, or around £40 to £60 an hour, and combining it with your EICR inspection often saves money and aligns the renewal dates.

Recording and documentation

Good records prove compliance and protect you against liability. A professional tester provides a certificate listing every appliance, its pass or fail status, the test date and the next due date. Keep these for at least six years in Scotland, where it is a legal requirement, and the same period in England and Wales as good practice. It is worth maintaining an appliance register for each property, noting what you provide, serial numbers where available and the testing history, which is invaluable in any dispute about what you supplied versus what the tenant added. Any appliance that fails must be taken out of service immediately and repaired or replaced before the tenant can use it again, with your inventory updated to match. Storing PAT certificates alongside your gas safety records and EICR in one place, with reminders set for renewals, keeps the whole electrical safety picture in view.

Why PAT testing matters beyond compliance

Even where it is not strictly mandatory, there are strong reasons to test. Electrical faults are a leading cause of accidental house fires in England, accounting for more than half of them, with faulty appliances behind a significant share, so testing catches hazards before they become fires. Tenant safety is the heart of it: a worn cable or damaged plug can cause a serious shock, and testing finds those faults early. There are commercial reasons too. Many landlord insurance policies expect proof of electrical safety, and an insurer may resist a claim involving an untested appliance. And if a tenant is injured by equipment you supplied, you have to show reasonable care, which is very hard to do without testing records.

Common mistakes to avoid

The most frequent error is confusing PAT with the EICR. An EICR examines the fixed installation, the wiring, sockets and consumer unit, while PAT covers plug-in appliances; you need both, and they run on different cycles. Do not assume new appliances are exempt, since testing establishes the baseline and any second-hand item should be tested before use. Do not leave a failed appliance in place "until you get to it", as that is exactly where liability bites; remove it straight away. And do not overlook outdoor equipment or the extension leads and adaptors you supply, which are frequently involved in incidents.

Building it into your routine

The simplest approach is to fold PAT testing into your annual landlord calendar alongside gas safety checks, EICR renewals and insurance reviews, and to schedule it for void periods when the property is empty. Coordinating PAT with the five-year EICR where possible reduces visits and keeps the renewal dates aligned. Budget for it as a routine cost rather than a surprise: PAT testing is typically £50 to £150 per property depending on the number of appliances, and an EICR £100 to £300.

Frequently asked questions

Is PAT testing a legal requirement for landlords?

Not in England and Wales, where it is not explicitly required by law but is the standard way to meet your duty to keep supplied appliances safe. In Scotland it is effectively mandatory, and it is commonly required as an HMO licence condition across the UK.

How often should a landlord PAT test?

There is no fixed legal interval. Best practice is to test before each new tenancy, then annually for high-risk items and every two to four years for lower-risk ones, with quick visual checks in between.

Do I need to test a tenant's own appliances?

No. You are only responsible for the appliances you supply. If you replace a tenant's appliance during the tenancy, however, the replacement becomes yours to test.

What is the difference between PAT and an EICR?

PAT covers plug-in appliances; an EICR inspects the fixed wiring, sockets and consumer unit. The EICR is a legal requirement in England every five years, while PAT is best practice in England and Wales and required in Scotland.

The underlying principle is the same across the UK: landlords must ensure the appliances they provide are safe. In Scotland that means testing; in England and Wales it is optional in law but practically essential for demonstrating duty of care and satisfying insurers. Keeping your certificates and renewal dates tracked in one place is exactly what August's document storage and reminders are built for, and it is free for up to two properties.
