EICR vs PAT Testing: What’s the difference?

While EICR and PAT testing are both concerned about electrical safety, they actually deal with different areas. Whether you are a landlord, homeowner or business owner, being  aware of the distinction helps to ensure you book the correct test (and also not be charged for anything unnecessary).

What is an EICR?

EICR stands for Electrical Installation Condition Report. It inspects the fixed wiring and permanent electrical installation in a property, including:

Consumer unit (fuse box)

Wiring in walls/ceilings

Sockets and light fittings

Earthing and bonding

RCD protection

The electrician inspects, tests, and then produces a report with the following observations coded:

C1: Danger (quick fix is required)

C2: Immediate risk (sorted within 24 hours)

C3: Improvement recommended

FI: Further investigation required

If a report includes C1, C2 or FI issues, then it is nearly always considered to be unacceptable in its current state.

What is PAT testing?

PAT : Portable Appliance Testing. It tests plug-in electrical appliances, not the wiring in the building. Examples include:

Kettles, microwaves, fridges

Hairdryers

Lamps

Extension leads

Computers and monitors

Vacuum cleaners

Radios

TVs

The process of PAT testing usually includes a visual inspection (damage to cables or plugs) as well as elective checks using a competent person and test instrumentation. And at that stage, items are marked off as pass/fail.

The simple difference

Fixed electrics such as a property’s wiring (EICR)

PAT for portable appliances that are plugged in.

Who usually needs what?

Landlords

EICR: Usually mandated to be conducted on a regular basis (typically every 5 years, or at change of tenancy – subject to regulation and age / property type).

PAT: Not a statutory requirement in all cases, however is often good practice where appliances are provided (e.g. furnished lets). For Electrical Testing Cheltenham, visit https://www.blu-fish.co.uk/electrical-services-cheltenham/electrical-testing-cheltenham

Homeowners

EICR – good for houses 15 years or older, when major building work has been done and should be carried out upon purchase of any property.

PAT – mostly unnecessary unless you conduct a home business with high-use gear that is used by others.

Businesses

EICR: Frequently required to help secure the premises.

PAT: For work places in rentals of equipment and anywhere appliances are used where public/patients use them.

What to ask before booking

Testing appliances and installations

Do you get a breakdown and written report of the works done?

Whether you are applying for a specific class of property (e.g., Rental/HMO/Commercial)?
