PAT Testing for Landlords: What It Is and Do You Need It?

What PAT Testing Is

Portable Appliance Testing (PAT testing) is a structured inspection and electronic testing process applied to portable electrical appliances — any electrical item that can be physically moved and is connected to the mains supply via a plug. The process combines a visual inspection with an electronic test using a PAT testing instrument, which applies a series of electrical tests to check the safety of the appliance's insulation and earthing.

The tests typically carried out during PAT testing include:

• Visual inspection: Checking the plug, cable, cable entry at plug and appliance, body of the appliance, and any visible components for damage, fraying, burning, or deterioration.
• Earth continuity test: Confirms that Class I appliances (those with a metal casing that requires earthing) have a continuous, low-resistance earth path from the plug earth pin through the cable to the appliance casing. A failed earth means a fault in the appliance could make the metal casing live.
• Insulation resistance test: Applies a high DC voltage (typically 500V) between the live and neutral conductors and the earth, measuring the resistance of the insulation. Very high resistance (typically above 1 megohm) confirms the insulation is intact. Low insulation resistance indicates the cable or appliance insulation has deteriorated and may pose a shock or fire risk.

Some PAT testing instruments also carry out a functional test — confirming the appliance powers on and operates — and a leakage current test for Class II (double-insulated) appliances that have no earth connection.

The Legal Position for Landlords

This is the point where landlords frequently receive conflicting information: PAT testing is not a statutory requirement for landlords in the way that gas safety certificates and EICRs are. There is no specific legislation in England that requires private landlords to PAT test electrical appliances provided with a tenancy on a fixed schedule.

However, the absence of a specific PAT testing statute does not mean landlords have no obligation in relation to supplied appliances. The relevant legislative framework includes:

• Electrical Equipment (Safety) Regulations 2016: Requires that electrical equipment supplied in the course of a business is safe. Landlords supplying electrical appliances as part of a furnished tenancy are providing electrical equipment in the course of a business and have an obligation to ensure it is safe.
• Consumer Protection Act 1987: Imposes strict liability for damage caused by unsafe products supplied in the course of a business. A landlord who supplies a faulty electrical appliance that causes a fire or injury faces civil liability under this framework.
• Homes (Fitness for Human Habitation) Act 2018: Requires properties to be fit for human habitation throughout the tenancy. A property with demonstrably unsafe electrical appliances supplied by the landlord could be considered unfit.

The practical position is: while no statute says "PAT test every two years," a landlord who supplies appliances and cannot demonstrate that those appliances are safe has significant civil and potentially criminal exposure if one of those appliances causes a fire or injury. PAT testing is the recognised method of demonstrating that due diligence has been applied to appliance safety.

HMO Licences and Insurance Policies

For landlords operating licensed Houses in Multiple Occupation (HMOs), the position is more specific. Many HMO licences issued by London boroughs include a condition requiring that all electrical appliances provided with the property are PAT tested and that valid test records are maintained. If your HMO licence contains such a condition, PAT testing is not optional — it is a licence requirement and failure to comply is a breach of licence conditions.

Landlord insurance policies increasingly include similar requirements. Some policies require evidence of recent PAT testing for claims relating to appliance-caused fires or electrical incidents to be valid. Review your policy documents carefully — a claim arising from a faulty landlord-supplied appliance on a property where no PAT testing has been carried out may be contested or refused.

Which Appliances Need Testing

PAT testing covers any landlord-supplied electrical appliance that connects to the mains via a plug or fixed connection and is capable of being moved. In a furnished rental property this typically includes:

• Washing machine and tumble dryer
• Refrigerator and freezer
• Dishwasher
• Microwave and toaster
• Kettle and other kitchen appliances
• Electric blankets (high-priority item — these deteriorate with folding and use)
• Lamps and floor-standing lighting
• Television and any audio/visual equipment
• Electric heaters or fans supplied with the property
• Vacuum cleaners or other cleaning appliances

Fixed electrical installations — socket outlets, light fittings, consumer unit, fixed wiring — are not PAT tested. These are covered by the EICR (Electrical Installation Condition Report) under the 2020 Private Rented Sector electrical safety regulations.

Tenants' own appliances are the tenant's responsibility and are not subject to landlord PAT testing obligations.

How Frequently Should PAT Testing Be Carried Out?

The HSE (Health and Safety Executive) guidance on PAT testing recommends a risk-based approach rather than a fixed interval for all appliances. For rental residential properties, the practical guidance applied by most professional PAT testers is:

• High-use appliances (washing machine, kettle, toaster, electric blanket): Annual testing or at each change of tenancy, whichever is sooner.
• Medium-use appliances (lamps, TV, vacuum cleaner): Every one to two years.
• Low-use or infrequently moved appliances (refrigerator, dishwasher): Every two to four years, though many landlords apply a standard two-year cycle to all appliances for simplicity.

For furnished rental properties, testing at every change of tenancy and annually thereafter is the most defensible approach. This ensures that any appliance damage caused by outgoing tenants is identified before the next tenancy begins, and provides an annual record of appliance safety.

Who Can Carry It Out?

PAT testing must be carried out by a competent person — someone with the skills, knowledge, and equipment to carry out the tests correctly and interpret the results. This does not require a specific licence, but in practice means either:

• A formally trained and qualified PAT tester (many hold City and Guilds 2377 or equivalent PAT testing qualifications)
• A qualified electrician, who may carry out PAT testing as part of their work

DIY PAT testing by the landlord is not appropriate unless the landlord has the relevant training and equipment. Consumer-grade PAT testers are available, but without the training to interpret results and the calibrated equipment to produce defensible records, self-testing does not provide the evidential protection that properly recorded professional testing does.

Cost

Professional PAT testing costs approximately £1–£3 per item for individual appliances when tested as part of a batch. Most PAT testers apply a minimum call-out or visit fee, typically £80–£150, which covers the first number of items. A furnished one-bedroom flat with eight to twelve appliances would typically cost £100–£150 for a professional PAT test including the visit charge and a written test record. Larger furnished properties with more appliances pay proportionally more, though the per-item cost generally reduces with volume.

The test record — typically a printed or digital appliance register showing each item tested, the test date, the result, and the tester's details — is the deliverable you need to retain. This is your evidence of due diligence if a claim is ever made against you in relation to an appliance.
