How long does an EICR take? Honest timings from the trade
In short: An EICR takes roughly 2 to 4 hours for a flat, 3 to 5 hours for a 3 bed house and most of a day for larger or older properties. The time goes on dead testing each circuit and inspecting accessories, so anything that increases circuits, limits access or raises the sampling rate extends the visit. Power is off for parts of the inspection.
Key points
- Roughly 2 to 4 hours for a flat, 3 to 5 for a 3 bed house, most of a day for larger or older homes.
- Most of the time is dead and live testing circuit by circuit, plus writing the report.
- Power is off in stages while dead tests are done.
- Clear access and labelled circuits are the single biggest thing that shortens the visit.
- A whole-house EICR done in an hour has cut a corner somewhere.
Customers ask how long an EICR takes because they are planning their day. Electricians should care about the same number for a different reason: time is the honest cost of an inspection, and quotes that undercut the market only work by cutting the hours. Our EICR pricing guide covers the money; this is where the hours go.
Typical durations
| Property | Typical time on site |
|---|---|
| 1 to 2 bed flat, modern board | 2 to 4 hours |
| 3 bed house | 3 to 5 hours |
| 4 to 5 bed or pre-1980s wiring | 5 to 8 hours |
| HMO or commercial unit | a day or more, scoped first |
Where the hours go
Visual inspection of the consumer unit and a sample of accessories. Dead tests on each circuit: continuity, insulation resistance, polarity. Live tests: earth fault loop impedance, prospective fault current, RCD operating times. Then the part customers never see, which is writing it up: every circuit on the schedule of test results, every observation coded C1 to C3 or FI with its location. On a ten-circuit house, the testing alone is two to three careful hours.
What makes it slower
Circuits without labels, boards in cupboards under stairs full of vacuum cleaners, furniture in front of the sockets that were going to be sampled, extensions wired by persons unknown, and any reading that does not make sense and has to be chased. An inspector who finds a borrowed neutral does not get to un-find it; the tracing time is in the job whether or not it was in the quote.
The quick-EICR problem
A whole-house EICR in an hour means one of two things. Either the sampling rate was minimal and the extent and limitations section quietly says so, or readings were invented. The first produces a report that protects nobody; the second is the kind of thing that ends scheme registrations. If a price seems to assume an hour on site, that is the corner being cut.
For electricians: the write-up is the slow part you can fix
The site hours are fixed by physics and the regs. The hour of evening paperwork is not: filling the schedule as you test, on the phone at the board, with the readings sanity-checked as they go in, means the report is finished when the tools are packed. That is the difference between a 4-hour job and a 4-hour job plus an evening, which across a week is most of a working day reclaimed.
Where a typical 3 bed afternoon goes
Broken down, a normal house inspection spends its hours roughly like this:
| Stage | Time on an average 3 bed |
|---|---|
| Visual inspection of the board and a sample of accessories | 30 to 45 minutes |
| Dead tests on each circuit (continuity, insulation resistance, polarity) | 1 to 1.5 hours |
| Live tests (loop impedance, prospective fault current, RCD times) | 45 minutes to 1 hour |
| Writing up the schedules and coding observations | 45 minutes to 1.5 hours |
The write-up is the only part that can happen off site, and it is the part a customer never sees and an electrician often does twice: once in shorthand at the board, once neatly that evening. Doing it once, at the board, is the single biggest time saving available on the job.
How to get a faster, cheaper inspection (for the customer)
You cannot shorten the testing, but you can stop the inspector spending an hour on everything around it. Before the visit: clear the cupboard the consumer unit lives in, move furniture away from the sockets that obviously need reaching, dig out any previous certificate, and write down anything you already know is odd (the socket that sparks, the light that trips the others). An inspector who can walk straight to the board and reach the accessories is testing, not excavating, and the bill reflects it.
Common questions
Will the power be off during an EICR?
Partly. Dead tests require circuits to be isolated, so expect the power off in stages for an hour or two across the visit. The inspector should sequence it so the fridge and freezer are off for as little time as possible.
Can an EICR be done in an hour?
Not properly on a whole property. A one-hour EICR on a house means either heavy sampling with broad limitations written into the report, or boxes ticked without testing. Either way the report's value collapses.
Do I need to be home for an EICR?
Someone needs to give access, and the inspector needs to reach the consumer unit, a representative spread of sockets and switches, and ideally the meter position. Empty properties are often quicker than occupied ones.
How long is an EICR valid for?
For a private rental in England, up to five years, or less if the report sets a shorter interval. The time the inspection takes and the time the report stays valid are two different questions people often merge.
Can I speed up my EICR?
Yes, by removing the friction. Clear access to the consumer unit and to sockets, label or point out the board, flag any known quirks, and make sure the inspector can reach the meter. Most lost time is spent moving furniture and hunting for circuits, not testing them.
Why does the inspector turn the power off?
Several of the tests have to be done dead, with the circuit isolated, because applying a test voltage to a live circuit would be dangerous and would give false readings. A good inspector sequences the isolations so the fridge and freezer are off for the shortest time possible.
