Is PAT Testing a Legal Requirement for Landlords?

For a standard private letting: no, PAT testing is not explicitly required by law.

For a licensed HMO: effectively yes — not through primary legislation, but through your licence conditions.

That distinction is the whole answer, and it is worth understanding properly rather than taking either extreme on trust.

The relevant duty comes from the **Electrical Equipment (Safety) Regulations**, which require that electrical appliances you supply with a property are **safe**. The Landlord and Tenant Act 1985 and the Homes (Fitness for Human Habitation) Act 2018 reinforce this.

Note what that says: the appliances must be safe. It does not say how you demonstrate it. PAT testing is the recognised method, not the legal requirement itself.

This matters in practice. If a tenant is injured by a faulty kettle you supplied, the question will not be "did you PAT test?" — it will be "can you show the appliance was safe?" A dated PAT certificate is the easiest way to answer that. Without one you are relying on your own assertion.

Note also that this only covers appliances **you** supply. Anything the tenant brings is theirs.

HMO licensing is where PAT testing becomes effectively compulsory.

Virtually every local authority in London attaches a condition to HMO licences requiring a current PAT certificate for the appliances supplied in the property, typically renewed annually. The requirement does not come from an Act of Parliament — it comes from your licence.

The consequence is more immediate than a fine. Failing to produce a current PAT certificate at licence application or renewal can mean **refusal or revocation**, and an unlicensed HMO is a far more serious problem than a missing certificate: rent repayment orders, a bar on possession, and prosecution.

If you let a licensable HMO, treat annual PAT testing as mandatory and check your specific borough's licence conditions, which vary.

Beyond HMOs, PAT testing earns its cost in a few situations:

• **Furnished and part-furnished lets** — the more appliances you supply, the more exposure you carry
• **Between tenancies** — the natural point to check, with no access to arrange
• **Older appliances** — anything over about five years, particularly kettles, toasters and heaters
• **Insurance conditions** — some landlord policies require it; worth reading yours rather than assuming
• **Student and shared lets** — high turnover, heavy use, more appliances

For an unfurnished flat where you supply nothing but an integrated oven, the case is much weaker. It is a judgement about how many appliances you have supplied, not a blanket rule.

An engineer visually inspects each appliance — plug, cable, casing — then uses a test instrument for earth continuity and insulation resistance. Each item gets a pass or fail label, and you receive a certificate and an asset register listing every appliance tested.

In London: **PAT testing from £59.99 inc VAT for up to 10 appliances**, with the certificate and asset register issued the same day. Commercial PAT from £79.99 for offices, shops and restaurants.

If your EICR is also due, both can be done in one visit — the EICR covers the fixed installation, PAT covers the things plugged into it. Call 07426 409342 or book online.
