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

Are EICR and PAT testing the same thing? It is one of the most common questions we hear from business owners and landlords across Manchester. The answer is no — they are complementary but fundamentally different inspections that cover different parts of your electrical safety picture. Understanding the distinction is essential because relying on only one leaves significant gaps in your compliance.

This guide explains what each test covers, how they differ, what they cost, and why every business and landlord needs both to achieve full electrical safety compliance.

What Is EICR? Electrical Installation Condition Report

An EICR is an inspection and test of the fixed electrical installation within a building. This covers everything that is permanently wired into the structure — the components you cannot unplug and take with you.

What gets inspected during an EICR:

All fixed wiring throughout the building — from the incoming supply to every socket, switch, and light fitting
Distribution boards (consumer units) — the panels that house your circuit breakers and fuses
Earthing and bonding systems — the safety connections that protect against electric shock
Protective devices — RCDs (residual current devices), MCBs (miniature circuit breakers), and fuses
Cable routes and connections — checking for damage, deterioration, and compliance
Permanently connected equipment — built-in ovens, boilers, fixed air conditioning units, and immersion heaters

Who needs an EICR:

All residential landlords in England — legally required under the 2020 Regulations
All commercial building owners and occupiers — required under health and safety legislation
Businesses with employees — employer duty of care under the Health and Safety at Work Act 1974
Property developers and investors — due diligence requirement for transactions
Anyone selling commercial property — routinely requested by buyers' solicitors

Typical frequency:

Residential rental properties — every 5 years or at change of tenancy
Commercial premises — every 5 years
Industrial and high-risk environments — every 3 years
Temporary installations — every 1 to 3 years

Cost range:

Small property (up to 5 circuits) — £300 to £400
Medium property (10 to 20 circuits) — £400 to £600
Large property (20+ circuits) — £600 to £1,000 or more

An EICR must be carried out by a qualified electrician registered with a competent person scheme such as NICEIC, NAPIT, or ELECSA. The inspection typically takes four to eight hours depending on the size and complexity of the installation.

What Is PAT? Portable Appliance Testing

PAT testing inspects portable electrical equipment — the items that plug into your fixed installation. These are the devices you can pick up, move, and unplug.

What gets tested during PAT:

Computers, monitors, and peripherals
Printers, scanners, and copiers
Kettles, microwaves, toasters, and fridges
Phone chargers and power supplies
Portable power tools — drills, saws, grinders
Fans, heaters, and desk lamps
Extension leads and multi-socket adapters
Any other device with a plug

What PAT does NOT test:

Fixed wiring — that is covered by the EICR
Distribution boards — that is covered by the EICR
Permanently installed equipment — that is covered by the EICR
Building earthing systems — that is covered by the EICR

Who needs PAT testing:

All businesses with portable electrical equipment — which is effectively every business
Schools, colleges, and universities
Hospitals, clinics, and care homes
Hotels, restaurants, and hospitality venues
Factories and manufacturing facilities
Landlords providing furnished properties with electrical appliances

Typical frequency:

Office equipment — annually
Heavy-use equipment in workshops — every 6 months
Industrial power tools — every 3 to 6 months
Light commercial (low-risk) — every 1 to 2 years
Frequency depends on a risk assessment of the equipment, its environment, and how it is used

Cost per appliance:

Typical cost — £2 to £10 per item
50 items — £100 to £500 annually
100 items — £200 to £1,000 annually
200+ items — £400 to £2,000 annually

PAT testing can be carried out by a competent person — this does not necessarily require a fully qualified electrician, though using a trained and insured technician is recommended for commercial environments.

Key Differences at a Glance

| Aspect | EICR | PAT | |---|---|---| | What is tested | Fixed electrical installations | Portable electrical equipment | | Covers | Wiring, circuits, distribution boards, earthing | Appliances, chargers, tools, extension leads | | Frequency | Every 3 to 10 years depending on property type | Annually or more frequently | | Typical cost | £300 to £1,000 per property | £2 to £10 per item | | Duration | 4 to 8 hours per property | 5 to 15 minutes per item | | Certification | EICR report with observations and codes | PAT label or sticker on each item, plus register | | Who performs it | Qualified electrician (NICEIC, NAPIT, ELECSA) | Competent trained person | | Legal basis | Multiple regulations (2020 Regs, HSE, Electricity at Work) | HSE guidance and employer duty of care |

The fundamental difference is scope: EICR assesses the building's permanent electrical system, while PAT assesses the movable equipment that plugs into it. Neither test covers what the other one does.

Why You Need Both: Coverage Gaps Explained

EICR alone leaves these gaps:

Having a satisfactory EICR means your building's fixed wiring is safe. But it tells you nothing about the hundreds of portable devices your staff plug in every day. A frayed laptop charger, a damaged extension lead, or a faulty kettle can cause electric shock or fire regardless of how well-maintained the fixed installation is. Staff bringing personal chargers and devices from home introduces equipment that has never been tested. Contractors bringing their own tools onto your premises adds further uncontrolled risk.

PAT alone leaves these gaps:

Having every portable appliance tested and labelled is good practice, but it provides no assurance about the wiring, circuits, and protective devices those appliances are connected to. An appliance can pass PAT testing perfectly yet still pose a danger if the socket it plugs into has a faulty earth, the circuit lacks RCD protection, or the cable behind the wall has deteriorated. PAT testing also does not meet landlord obligations — a landlord who has PAT testing but no EICR is non-compliant.

Real-world scenarios where both are essential:

Office environment: The EICR confirms that the building's wiring, distribution boards, and earthing are safe. PAT testing confirms that every computer, printer, charger, kettle, and extension lead used by staff is in safe condition. Together, they provide complete coverage from the incoming supply to the plug on every device.

Factory or workshop: The EICR tests the factory's fixed electrical system — three-phase supplies, motor circuits, lighting, and power distribution. PAT testing covers portable power tools, hand-held equipment, and bench-mounted appliances. Without both, significant electrical risks go unassessed.

Retail premises: The EICR covers the shop's wiring, lighting circuits, and fixed equipment. PAT testing covers point-of-sale terminals, barcode scanners, card readers, and any portable appliances in staff areas. A fire caused by a faulty till charger is no less devastating than one caused by faulty wiring.

Cost Comparison and Budgeting

When you combine EICR and PAT testing costs, the total annual investment in electrical safety compliance is modest compared to the risks:

Small office (10 staff, 50 appliances):

EICR: £400 every 5 years = £80 per year
PAT: £250 annually
Total: approximately £330 per year

Medium business (50 staff, 200 appliances):

EICR: £700 every 5 years = £140 per year
PAT: £800 annually
Total: approximately £940 per year

Large facility (200+ staff, 500 appliances):

EICR: £1,200 every 5 years = £240 per year
PAT: £2,000 annually
Total: approximately £2,240 per year

Compare these figures to the potential costs of non-compliance: HSE fines of up to £30,000 per offence, forced business shutdowns, personal liability if an accident occurs, invalidated insurance claims, and reputational damage. The investment in both EICR and PAT testing delivers a clear return.

Manchester Regulatory Context

Across Greater Manchester, HSE enforcement of electrical safety standards has increased. Local councils — Salford, Stockport, Oldham, Tameside, and Rochdale — actively inspect both residential and commercial properties for compliance. Common enforcement findings include landlords without a current EICR, businesses without a PAT testing programme, inadequate testing intervals, and poor documentation of compliance activities.

Getting compliant quickly is straightforward: contact a NICEIC-registered provider who offers both EICR and PAT services, schedule your inspections, address any remedial work identified, and maintain your documentation.
