What is an EICR?
A check of your building's electrical system to make sure it's safe.
Is an EICR a legal requirement?
It depends.
For rented homes, yes — the Electrical Safety Standards Regulations 2020 require an EICR every 5 years.
For commercial premises, you're legally required to keep electrical systems safe under the Electricity at Work Regulations 1989, and an EICR is the standard way to prove it.
Do I need an EICR for my business?
Yes. It's the simplest way to prove your electrics are safe for staff, insurers, and regulators.
Why do businesses actually get an EICR?
To reduce risk. It helps prevent fires, avoids downtime, and protects you if something goes wrong.
Who is responsible for getting an EICR?
You are. If you own, manage, or control the building, it's your responsibility.
How often do I need an EICR?
Usually every 5 years for offices, shops, and standard commercial premises. More often for higher-risk environments (industrial, wet, dusty, or high-occupancy). Rented homes: every 5 years.
What affects how often I need an EICR?
Usage, environment, and condition of the installation.
What happens if I don't have an EICR?
You carry the risk. If there's an incident, you'll struggle to prove your electrics were safe.
Can I do an EICR myself?
No. It must be done by a qualified electrician.
What does an EICR actually involve?
Testing circuits and inspecting wiring to find faults or risks.
What is a "circuit" in an EICR?
A single electrical route. For example: a lighting circuit or a socket circuit.
Does an EICR mean switching power off?
Yes, usually. Parts of the system need to be isolated to test properly.
How long does an EICR take?
It depends on size. Small sites: a few hours. Larger sites: a full day or more.
How much does an EICR cost?
It depends on the number of circuits. More circuits = more time = higher cost.
Will an EICR disrupt my business?
Some disruption. But it can usually be planned to minimise impact.
Can an EICR fail?
Yes — if there are dangerous or potentially dangerous issues.
What's an unsatisfactory EICR?
An EICR with C1 or C2 codes — meaning dangerous or potentially dangerous faults. The installation is not safe to use until the issues are fixed.
What happens if my EICR fails?
You need to fix the issues. Serious faults must be dealt with immediately.
What do EICR codes mean (C1, C2, C3)?
C1 = immediate danger. C2 = potentially dangerous. C3 = improvement recommended.
Do I need to fix C1 and C2 issues?
Yes. These are safety risks and must be addressed.
Do I need to fix C3 issues?
No. But if something goes wrong and you ignored it, you could still be liable and your insurance may be affected.
Do new buildings need an EICR straight away?
No — but they need an Electrical Installation Certificate (EIC) from the installer when first wired. The first EICR is typically due 5 years later.
Do I need an EICR for an office?
Yes. All workplaces need safe electrical systems.
Do small businesses need an EICR?
Yes. The risk is the same regardless of size.
Do landlords need an EICR?
Yes. In England, EICRs are required for all rented homes every 5 years. Scotland, Wales, and Northern Ireland have parallel rules with slightly different timings.
How often do landlords need an EICR?
Every 5 years. Or at change of tenancy.
What's the difference between an EICR and PAT testing?
An EICR checks the building wiring. PAT testing checks plug-in equipment.
Does an EICR include appliances?
No. Only the fixed electrical installation. Plug-in items are covered by PAT testing.
How long is an EICR valid for?
Typically 5 years. But may be shorter depending on risk.
Can I use an old EICR?
Only if it's still in date and nothing has changed.
What triggers a new EICR?
Damage, changes, or concerns about safety.
Do insurers require an EICR?
Often, yes. It helps prove your property is safe.
What's the real purpose of an EICR?
To prevent electrical fires and keep people safe. Everything else is proof.
