How long does an EICR take? Honest timings for London properties
Short answer: two to three hours for a one or two bedroom flat, three to four hours for a typical three bedroom house, and half a day or more for a larger house or a licensed HMO. The certificate is issued the same day.
The longer answer matters, because the time an EICR takes is driven almost entirely by circuit count — not floor area, and not the number of bedrooms. A compact two-bedroom flat with fourteen circuits takes longer than a three-bedroom house with eight.
Typical EICR timings by property type
- Studio or one-bed flat (4–6 circuits) — 1.5 to 2 hours
- Two-bed flat (6–8 circuits) — 2 to 3 hours
- Three-bed house (8–10 circuits) — 3 to 4 hours
- Four or five-bed house, or one with an extension and outbuildings (10–16 circuits) — 4 to 6 hours
- Licensed HMO with multiple consumer units — 5 hours to a full day, priced on circuit count
- Small commercial unit or shop — half a day upwards, depending on three-phase supply and distribution boards
All of the above assume reasonable access. Add time if the consumer unit is boxed in, if sockets are behind furniture, or if the loft hatch is painted shut.
Why the power has to go off — and for how long
An EICR is not a visual walk-round. It includes dead testing — continuity of protective conductors, insulation resistance, polarity — and that work can only be done with the installation isolated. In practice the power is off in blocks rather than for the whole visit.
For a two-bedroom flat, expect the supply to be off for roughly 45 minutes to 90 minutes in total, usually split into two or three periods. For a larger house it can be two to three hours. We can often work circuit by circuit to keep a fridge or a home office running, but that adds time to the overall visit, so it is worth saying up front if it matters to you.
If you work from home, the practical advice is to plan for a morning without power rather than assume you can carry on around us.
What makes an EICR take longer
- No existing paperwork. If there is no previous certificate and no circuit schedule, the whole installation has to be mapped from scratch. This is the single biggest variable and can add an hour or more.
- Multiple consumer units. Common in period houses that have been extended, and in converted flats. Each board needs its own set of tests.
- Inaccessible cabling. Boarded lofts, boxed-in risers and buried junction boxes all slow things down.
- Faults found during testing. A low insulation resistance reading has to be traced to the circuit and, ideally, to the section causing it. That is time well spent — it is the difference between a report saying “C2, investigate” and one that tells you exactly what to fix.
- Old rewireable boards. Rewireable fuses take longer to isolate and reinstate safely than modern breakers.
How long until I get the certificate?
We issue the signed PDF the same day the inspection is completed, along with a plain-English summary of what each observation code means. There is no waiting for it to be typed up at the end of the week.
That matters for landlords: the regulations require you to supply the report to existing tenants within 28 days of the inspection, to a new tenant before they occupy, and to the local authority within seven days of a written request. A same-day certificate removes any risk of missing those windows.
And how long is an EICR valid for?
- Rented residential property — every 5 years, or at change of tenancy if the inspector recommends it
- Owner-occupied house — recommended every 10 years
- Owner-occupied flat — recommended every 10 years
- Licensed HMO — every 5 years, and usually required as part of the licence
- Commercial premises — every 5 years, or as specified by the previous report
An inspector can specify a shorter interval than the default, and that shorter date is the one that counts.
If the report comes back unsatisfactory
Any C1 (danger present) or C2 (potentially dangerous) code makes the report unsatisfactory. C1 items are made safe on the day as a matter of course. Everything else has to be remedied within 28 days, or sooner if the report specifies, with written confirmation to the tenant and to the council.
Since the Renters’ Rights Act took full effect on 1 May 2026, the maximum penalty for failing to hold a valid electrical safety certificate is £40,000 per offence, up from the old £30,000 cap. The 28-day clock is the part landlords most often miss — the inspection being booked is not the same as the property being compliant.
What it costs
Our EICR starts from £140 for a standard one or two bedroom flat, with larger properties and HMOs priced on circuit count and quoted before we attend. Minimum charge on any visit is £108 (£90 + VAT). All prices are labour only; materials are itemised separately.
We do not shorten the inspection to hit a headline price. A £69 EICR is generally either a limited sample of circuits or a loss-leader attached to a remedial quote — and a sampled inspection that takes an hour is not the same document as a full one that takes three.
