An EICR and a PAT test both relate to electrical safety, but they cover different parts of a property’s electrical system and serve different purposes.
Electrical Installation Condition Report (EICR)
An EICR assesses the fixed electrical installation within a property.
This includes:
- Consumer units and distribution boards
- Fixed wiring (cables within walls, floors and ceilings)
- Fixed accessories such as sockets, switches and light fittings
- Earthing and bonding arrangements
An EICR looks at the overall condition and safety of the installation and is used to demonstrate compliance with electrical safety regulations, particularly for landlords and duty holders.
Portable Appliance Testing (PAT)
A PAT test assesses the safety of portable electrical appliances.
This includes:
- Kettles, microwaves and fridges
- Computers, monitors and office equipment
- Extension leads and portable heaters
- Any electrical appliance with a plug that can be moved
PAT testing focuses on whether individual items of equipment are safe to use and forms part of an employer’s or landlord’s duty to maintain electrical equipment.
KEY DIFFERENCES AT A GLANCE
EICR: Fixed wiring and electrical installation
PAT: Portable, plug-in appliances
EICR: Periodic inspection of the property’s electrical system
PAT: Ongoing inspection and testing of equipment
EICR: Typically required every few years
PAT: Carried out at intervals based on risk
Do I need both?
In many settings — such as workplaces, public buildings or rented properties where appliances are provided — both an EICR and PAT testing may be required to fully demonstrate electrical safety compliance.
L123 Ltd helps clients understand their obligations and can deliver both EICR and PAT testing as part of a coordinated compliance program.
