How Often Is an EICR Required?

How often an EICR is required depends on the type of premises, how it is used, and the environment it operates in. There is no single figure that applies everywhere — the maximum interval is a starting point that a competent person can shorten based on the condition and risk of the installation.

Common maximum intervals

BS 7671 and IET guidance set recommended maximum periods between inspections. Widely used benchmarks include:

• Rented homes (England): at least every 5 years — a legal requirement under the 2020 Regulations.
• Owner-occupied homes: recommended at least every 10 years, or on change of occupancy.
• Commercial and industrial premises: commonly 5 years, subject to risk assessment.
• Higher-risk environments (for example swimming pools, construction sites, agricultural premises): shorter intervals, sometimes 1–3 years.

Why the interval can be shorter

The competent person completing an EICR records a recommended date for the next inspection. This may be earlier than the maximum where:

• the installation is older or shows signs of deterioration;
• the premises has heavy use, harsh conditions, or a history of faults;
• there has been a change of use or occupancy; or
• the installation has been altered or extended.

Change of occupancy and events

An EICR is also good practice — and sometimes required — at particular points:

• Change of tenant or owner for rented and sold property.
• After significant alteration to the installation.
• Following a suspected fault, fire, or flood affecting the electrics.

Keeping evidence

Whatever the interval, duty holders should keep the report and any remedial certificates, and diarise the next due date. A compliance calendar across a portfolio prevents reports lapsing and demonstrates a proactive approach to safety — which is exactly what enforcement bodies expect to see.
