EICR vs PAT Testing: What's the Difference and Do You Need Both?

EICR and PAT testing are both important parts of electrical safety — but they test completely different things. Confusing the two is a common mistake that can leave landlords and business owners with gaps in their compliance. Here is a clear breakdown of what each one covers.

What Does an EICR Test?

An EICR (Electrical Installation Condition Report) tests the fixed electrical installation in a building — the wiring, consumer unit, sockets, switches, earthing and bonding. It does not test any portable appliances or equipment. Think of it as a health check for the building's electrical infrastructure.

What Does PAT Testing Cover?

PAT (Portable Appliance Testing) tests individual portable electrical appliances — kettles, computers, extension leads, power tools, and so on. It checks that the appliance itself is safe to use. PAT testing does not assess the fixed wiring or consumer unit in any way.

Do Landlords Need Both?

For residential landlords, an EICR is a legal requirement every 5 years. PAT testing of appliances provided with the tenancy (white goods, lamps, etc.) is not a legal requirement for residential landlords, but it is strongly recommended as best practice and may be required by your insurance policy.

What About Businesses?

For commercial premises, both EICR and PAT testing are important. The Health and Safety at Work Act and the Electricity at Work Regulations 1989 require employers to maintain electrical equipment in a safe condition. This covers both the fixed installation (EICR) and portable appliances (PAT). The frequency of each depends on the type of business and the risk level.

How Often Should Each Be Done?

EICR: Every 5 years for rental properties; every 10 years for owner-occupied homes; every 3-5 years for commercial premises. PAT Testing: Annually for most commercial environments; every 1-2 years for low-risk offices; more frequently for high-risk environments like construction sites.
