How Often Should an EICR Be Carried Out?

There is no single interval that fits every building. The usual pattern is this:

Owner-occupied homes: about every ten years is the common recommendation, and also when you move into a property you have just bought. This is good practice rather than a rule for most homeowners.

Rented homes: at least every five years, and this is a legal requirement for most private landlords in England.

Commercial premises: usually five years or less, depending on the use of the building and what the previous report said.

The interval is a maximum, not a target. If an inspector finds the installation is deteriorating, they can recommend an earlier re-inspection.

If you let a property, the electrical installation must be inspected and tested by a competent person at intervals of no more than five years. Landlords must give tenants a copy of the condition report, and must also give it to the local authority if asked. A new tenant should be given the latest report before they move in.

If the report is unsatisfactory, landlords must carry out the remedial work within the period set by the rules and confirm in writing that it has been done. Rules can change, so check GOV.UK for the current position, especially if you let in Wales, Scotland or Northern Ireland, where the arrangements differ.

The answer to "is an EICR three years or five years?" is therefore normally five for a rental, unless the report names a shorter period.

Shops, offices, workshops and other commercial premises generally need periodic inspection and testing as part of their duty to keep electrical systems safe. Five years is a common maximum, but busier or harsher environments, such as places with heavy equipment use, dust, damp or public access, often justify shorter gaps.

People sometimes ask how often an EICR is needed for healthcare buildings such as NHS sites. Those organisations usually follow their own stricter standards and maintenance schedules, so the figure for a typical shop or office does not apply. If you manage premises like this, follow your own policy and the advice in your most recent report.

Do not wait for the due date if any of these apply:

You have just bought an older property and do not know the age or state of the wiring.

The consumer unit is very old, has rewireable fuses, or has no RCD protection.

You notice flickering lights, warm sockets, burning smells, buzzing, tripping circuits or scorch marks.

There has been water damage, a fire, or major building work.

A new tenant is moving in and the last report is close to expiry.

A condition report is a snapshot. Installations can be altered, overloaded or damaged after the date of the test, so an in-date report does not always mean the system is still sound.

An EICR does not expire on a fixed date for every property. The report states a recommended date for the next inspection, and it is valid until then as long as the installation has not been altered or damaged.

The result is either satisfactory or unsatisfactory. Observations are coded: C1 means danger is present, C2 means potentially dangerous, C3 means improvement is recommended, and FI means further investigation is needed. A C1, C2 or FI usually makes the report unsatisfactory, and remedial work is then needed before it can be treated as satisfactory.

Keep every report safely. Mortgage lenders, letting agents, insurers and the next inspector may all ask for it.

If you want an EICR for a property in Billericay or elsewhere in Essex, use the enquiry form and say whether it is a home, rental or commercial unit, roughly how old the wiring is, and whether you have a previous report.
