How Often Should Landlords Arrange PAT Testing?

A kettle with a damaged lead, a loose plug on a supplied lamp, or a second-hand washing machine that has never been checked can quickly become a landlord’s problem. The question of how often PAT testing landlords should arrange does not have one fixed answer, but it does come down to a clear duty: any electrical appliance you provide must be safe for your tenant to use.

For most rented homes, an annual PAT test is a sensible, easy-to-manage routine for portable appliances supplied by the landlord. However, the right interval can be shorter or longer depending on the appliance, its condition, how it is used and the type of tenancy. A good testing plan is about reducing risk, not simply putting a sticker on everything once a year.

Is PAT testing legally required for landlords in Scotland?

There is no single law that says every landlord must PAT test every appliance every 12 months. What the law requires is that electrical equipment supplied as part of a tenancy is maintained in a safe condition.

In Scotland, private landlords must also meet wider electrical safety requirements, including having the installation inspected and tested through an Electrical Installation Condition Report (EICR) at the required intervals. An EICR checks the fixed installation - such as the consumer unit, sockets, wiring, switches and light fittings. PAT testing is different. It checks portable or movable appliances supplied with the property.

That distinction matters. A satisfactory EICR does not confirm that a fridge, microwave, extension lead or table lamp is safe. Equally, a passed PAT test does not tell you whether the fixed wiring is in good order. Both form part of a sensible electrical safety approach where relevant.

PAT testing is a recognised way of demonstrating that you have taken reasonable steps to check supplied appliances. It gives you a record of inspection and testing, identifies faults before they become serious, and makes it much easier to show what has been done if a concern is raised later.

How often should landlords arrange PAT testing?

For a standard private rented flat or house with ordinary domestic appliances, once a year is commonly recommended. It is a practical frequency that catches wear and tear without creating unnecessary disruption for tenants.

That said, annual testing is not a universal rule. A low-use appliance in good condition, such as a fixed table lamp in a rarely used room, may not need the same attention as an extension lead, vacuum cleaner or kitchen appliance used every day. In contrast, appliances in an HMO, holiday let, serviced accommodation or a property with frequent tenant changes may benefit from more regular checks.

A sensible approach is to carry out a visual inspection at every change of tenancy, then arrange PAT testing annually for landlord-provided portable equipment. If an appliance shows signs of damage, trips the electricity supply, gives off a burning smell, becomes unusually hot or has a loose plug or cable, it should be taken out of use straight away and checked - regardless of when it was last tested.

A useful risk-based testing schedule

The best schedule depends on use, condition and the likelihood of damage. As a general guide, consider the following:

• Every 12 months: Appliances supplied in an occupied rental property, particularly items used regularly such as kettles, microwaves, vacuum cleaners, washing machines and extension leads.

• At each change of tenancy: A visual check of all supplied appliances, cables, plugs and sockets, with testing where condition is uncertain or the appliance has had heavy use.

• More often than annually: Appliances in communal areas, HMOs, short-term lets or properties where equipment is used heavily by several people.

• Immediately when concerns arise: Any appliance with visible damage, overheating, intermittent operation, a damaged flex or signs of water ingress.

The test interval should be proportionate. Testing a new, good-quality appliance every few months in a quiet one-bedroom flat is unlikely to add much value. Ignoring an old extension lead with a taped-up cable because it passed last year is equally unwise.

Which landlord-supplied items need checking?

PAT testing normally applies to portable electrical appliances supplied with the tenancy. This includes appliances with a plug, as well as some items that are wired into a fused connection unit but can be moved or are considered electrical equipment rather than part of the fixed installation.

Typical items include white goods such as fridges, freezers, washing machines, tumble dryers and dishwashers; kitchen items such as kettles, toasters and microwaves; and household equipment such as lamps, vacuum cleaners, fans, televisions and extension leads.

It is easy to overlook smaller items. Multi-way extension leads, chargers supplied with equipment, portable heaters and plug-in air fresheners can all become damaged through regular use. Extension leads deserve particular attention because they are often overloaded, trapped under furniture or used where a proper additional socket would be safer.

Tenant-owned appliances are normally the tenant’s responsibility. If a tenant brings their own television, microwave or air fryer, the landlord is not generally expected to PAT test it. The responsibility changes if you provide the item, leave it in the property for tenant use, or take on a specific obligation within the tenancy agreement.

PAT testing is more than a pass or fail label

A proper PAT test usually starts with a close visual inspection. Many electrical faults are visible before a tester is connected: cracked plugs, damaged flexes, missing cable grips, scorch marks, loose sockets or unsuitable extension leads.

The electrical tests then check relevant safety points, depending on the type of appliance. These can include earth continuity for Class I items, insulation resistance and polarity. Double-insulated appliances, often marked with a square within a square, do not require an earth test in the same way as metal-bodied appliances, but they still need inspection and appropriate testing.

A pass label can be useful for quick identification, but the certificate or test record is the important part. Keep a clear register showing the property address, appliance description, make or identifying details where available, test date, result, defects found and any remedial work completed. Retain previous records as well, rather than only the latest certificate.

What to do when an appliance fails

A failed appliance should not be left in the property for a tenant to keep using. Remove it from service, label it clearly if necessary, and decide whether it can be safely repaired by a competent person or should be replaced.

Small repairs, such as fitting a correct plug or replacing a damaged flex, can sometimes be straightforward. But repeated faults, damaged casings, water damage or older appliances with questionable reliability often make replacement the better choice. A cheap appliance is not a saving if it creates a safety risk, a call-out or damage to the property.

If the failure has caused tripping or there is any doubt about the socket or circuit, the fixed installation should be checked too. The problem may not be limited to the appliance.

Avoid the common landlord mistakes

The most common mistake is assuming the EICR covers everything electrical in the home. It does not cover portable appliances in the same way, so supplied white goods and plug-in items can be missed.

Another is relying on a test label without looking at the appliance during inspections. Tenants may move furniture, replace leads, overload adaptors or accidentally damage equipment after the test date. A quick visual check between tenancies is worthwhile and takes very little time.

Finally, do not keep an unsafe appliance simply because it came with the property. If it is not needed for the tenancy, remove it. Any electrical item you leave for the tenant’s use becomes something you should be able to show is safe and maintained.

Arrange testing around your tenancy, not after a problem

The least disruptive time to inspect appliances is usually between tenancies, when you can check the property, deal with minor repairs and prepare it properly for the next occupant. Annual PAT testing can then be planned alongside other routine checks rather than becoming an urgent job after an appliance fails.

Keeping appliances safe is not about overcomplicating compliance - it is about leaving your tenant with equipment you would be comfortable using yourself.
