EICR vs PAT Testing: What's the Difference for Liverpool Businesses?

An Electrical Installation Condition Report (EICR) assesses the safety and condition of a property's fixed electrical installation. This includes the wiring inside walls, the consumer unit, distribution boards, fixed sockets, light fittings, and earthing and bonding arrangements. It does NOT cover portable appliances.

For businesses in Liverpool, an EICR is essential for insurance compliance, health and safety obligations, and lease requirements. Most commercial insurance policies now require a valid EICR, and many commercial landlords stipulate regular EICR inspections as a condition of the lease.

Commercial EICRs are typically required every 3-5 years depending on the type of premises. High-risk environments such as industrial sites, workshops and food preparation areas may need more frequent inspections. The inspection must be carried out by a NAPIT or NICEIC registered competent person.

Portable Appliance Testing (PAT) is the examination of portable electrical equipment to ensure it is safe to use. This includes kettles, microwaves, computers, printers, extension leads, phone chargers, power tools and any other equipment that plugs into a socket.

Unlike an EICR, which looks at the fixed installation, PAT testing focuses on the appliances themselves. The process involves a visual inspection for damage, followed by electrical tests using a portable appliance tester. These tests check earth continuity, insulation resistance and polarity.

PAT testing is not a legal requirement in itself, but the Electricity at Work Regulations 1989 require all electrical equipment in the workplace to be maintained in a safe condition. PAT testing is the most common and recognised way for Liverpool businesses to demonstrate compliance with this duty.

The fundamental difference is what each test covers. An EICR examines the fixed wiring and infrastructure of the building — the permanent electrical system that delivers power to sockets and light fittings. PAT testing examines the portable equipment that plugs into those sockets.

Another key difference is frequency. EICRs for commercial premises are typically every 3-5 years. PAT testing frequency depends on the type of equipment and environment — office equipment may need annual testing, while power tools on construction sites may need testing every 3 months.

The person carrying out the test also differs. EICRs must be conducted by a qualified, registered electrician with inspection and testing certification. PAT testing can be carried out by a competent person who has received PAT-specific training, although many businesses prefer to use a qualified electrician for both services.

Having a valid EICR but no PAT testing leaves a significant safety gap. Even if your fixed wiring is perfect, a faulty kettle or damaged extension lead can cause electric shock or fire. Conversely, PAT testing every appliance does not help if your building's wiring is deteriorating or your consumer unit is outdated.

Insurance companies increasingly expect both EICR and PAT testing records for commercial premises. If an electrical incident occurs and you cannot produce evidence of regular testing and maintenance, your insurer may refuse to pay out, leaving your business exposed to significant financial liability.

At Conaty&Co., we offer combined EICR and PAT testing packages for Liverpool businesses. This is more cost-effective than booking separately, ensures consistent documentation, and means you only deal with one contractor for all your electrical compliance needs. We provide digital certificates, reminder services and priority booking for annual renewals.
