EICR vs PAT Testing: What’s the Difference?
Electrical safety is one of the most important responsibilities for homeowners, landlords
and businesses across London. However, many people still confuse EICR inspections with PAT testing,
often assuming they are exactly the same thing. In reality, these two electrical checks serve
completely different purposes.
At
London Electricians,
we regularly help property owners understand which electrical inspection they actually need
and why both tests can sometimes be equally important. Whether you manage rental properties,
run a business or simply want a safer home, understanding the difference between EICR and PAT
testing can help you stay compliant and avoid serious electrical risks.
Although both inspections focus on electrical safety, they test different parts of a property’s
electrical system. One checks the fixed installation, while the other focuses on portable appliances.
What Is an EICR?
EICR stands for Electrical Installation Condition Report. This inspection assesses the safety
and condition of a property’s fixed electrical installation.
During an EICR inspection, electricians examine:
- Consumer units and fuse boards
- Electrical wiring throughout the property
- Sockets and switches
- Earthing and bonding systems
- Overloaded circuits
- Potential fire hazards
- Signs of damaged or ageing wiring
The purpose of an EICR is to identify hidden electrical dangers that may not be visible during
everyday use. Faulty wiring, overloaded circuits and poor installations can all increase the
risk of electric shock or fire.

London Landlord EICR Certificates
are particularly important for rental properties because landlords have legal responsibilities
to ensure tenant safety.
What Is PAT Testing?
PAT testing stands for Portable Appliance Testing. Unlike an EICR, PAT testing focuses on
electrical appliances rather than the property’s fixed wiring.
PAT testing commonly includes:
- Kettles
- Microwaves
- Computers
- Extension leads
- Printers
- Vacuum cleaners
- Portable heaters
- Kitchen appliances
The inspection checks whether appliances are safe to use and whether cables, plugs or
internal electrical components show signs of wear or damage.
PAT testing is especially common in:
- Offices
- Schools
- Rental properties
- Hotels
- Commercial buildings

Who Needs EICR and PAT Testing?
Both homeowners and businesses can benefit from electrical inspections, but certain properties
are legally required to carry them out.
Landlords
Landlords in England are legally required to obtain an EICR for rental properties at least
every five years. Furnished rental properties should also consider PAT testing for portable
appliances supplied to tenants.
Businesses
Employers have a duty of care to maintain safe electrical equipment in workplaces.
PAT testing is commonly used to demonstrate compliance with health and safety obligations.
Homeowners
While not always legally required, EICR inspections can help homeowners identify ageing wiring,
overloaded circuits and potential electrical hazards before they become dangerous.
Legal Requirements for Electrical Safety in the UK
UK electrical regulations continue to become stricter, especially for landlords and commercial properties.
Current landlord regulations require:
- An EICR every 5 years
- Electrical faults repaired within specified timeframes
- Proof of inspection records for tenants
PAT testing itself is not specifically required by law in every situation. However, businesses
and landlords still have legal obligations to ensure electrical appliances are safe.

Which Electrical Test Do You Actually Need?
The answer depends entirely on your property type and situation.
You probably need an EICR if:
- You own a rental property
- Your property has old wiring
- You recently purchased a property
- You notice electrical faults or tripping circuits
- You want to improve overall electrical safety
You may need PAT testing if:
- You provide appliances in rented accommodation
- You run a business or office
- Employees regularly use electrical equipment
- You manage commercial properties
In many cases, landlords and businesses require both inspections for complete electrical safety compliance.

Final Thoughts
Although EICR and PAT testing are often mentioned together, they serve very different purposes.
EICR inspections focus on the property’s fixed electrical installation, while PAT testing checks
portable appliances for safety issues.
