How Long Does an EICR Take, and How Often Do You Need One?

Booking an EICR often raises two practical questions before anything else: how much disruption is it going to cause on the day, and how often do you actually need to do this. Both answers depend mostly on the size and age of the property, so here is what to expect.

How Long the Inspection Itself Takes

An EICR involves testing every circuit in a property individually, so the time it takes scales with the number of circuits, not just the number of rooms. As a general guide:

  • One-bedroom flat: around ninety minutes to two hours
  • Two or three-bedroom house: around two to four hours
  • Four-bedroom or larger property: half a day or more, particularly if the wiring includes several generations of previous work
  • Commercial premises: varies significantly with the number of distribution boards and circuits, often booked across a full day or split across more than one visit

Older properties with a mix of wiring ages, or installations with poor labelling on the consumer unit, tend to take longer because each anomaly has to be traced and understood individually rather than simply tested and recorded.

What Actually Happens During the Visit

The electrician starts with a visual inspection, checking the condition of the consumer unit, accessible wiring, sockets, switches and fittings for obvious signs of damage or wear. They then carry out a series of electrical tests on each circuit, checking insulation resistance, earth continuity, and that protective devices like RCDs and circuit breakers operate correctly within the required time. Because this involves switching circuits off in turn, you should expect brief interruptions to power in different parts of the property throughout the visit, though the whole house is never without power for the full duration.

If you have equipment that genuinely cannot be interrupted, such as a fish tank pump, a freezer full of stock, or medical equipment, mention this when you book so the visit can be planned around it.

How Often You Need an EICR

How frequently you need a new EICR depends on how the property is used:

Rental properties

Under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, landlords must have a valid EICR in place at intervals of no more than five years, or sooner if the previous report recommends an earlier date. A new report is also required before a new tenancy begins if the existing one has expired. Full detail on this legal requirement is in our guide to EICR requirements for landlords.

Owner-occupied homes

There is no legal requirement for homeowners, but the widely recommended interval is every ten years. It is also worth commissioning one when buying a property, if you are not confident about its electrical history, before starting a major renovation, or if the installation has never been tested and the property is more than 20 years old.

Newly built or recently rewired properties

A property that has just received an Electrical Installation Certificate (issued after a new install or a full rewire) does not need an EICR straight away. That certificate effectively covers the installation until the standard interval, five or ten years depending on use, comes around.

What Happens Next

At the end of the inspection, you receive a signed, dated report classifying any issues found using the standard C1, C2 or C3 codes. If you want to understand exactly what those mean and how urgently each needs addressing, we cover it in full in what happens if your EICR gets a C1, C2 or C3 code.

Frequently Asked
Questions

If you have a question we have not answered here, just get in touch with the team.

Yes, briefly. Circuits need to be switched off in turn while they are tested, so there will be short periods without power in different parts of the property. Let your electrician know in advance if there is equipment that cannot be interrupted, such as a fish tank, freezer full of stock, or medical device, so they can plan around it.

Yes, most EICRs are carried out in occupied homes without any issue. The electrician simply needs reasonable access to the consumer unit, sockets and fittings throughout the visit.

If you cannot find any record of a previous EICR, treat that as a strong signal to book one soon, particularly on a property over 20 years old. There is no way to know the condition of the installation until it has been properly inspected.
