Quick Answer
Most domestic EICRs take between one and four hours. A small flat typically takes one to two hours. A standard three-bedroom house usually takes two to four hours. Larger homes, HMOs, and commercial premises can take four to six hours or longer.
Time by Property Type
| Property Type | Typical Duration |
|---|---|
| Studio or one-bedroom flat | 1 to 2 hours |
| Two to three-bedroom house | 2 to 4 hours |
| Four or more bedroom house | 4 to 6 hours |
| HMO | 4 to 6 hours or more |
| Small commercial unit | 4 hours to a full day |
| Large commercial or industrial site | A full day or more |
These ranges assume straightforward access with no major faults found along the way. Real appointments can run shorter or longer depending on the factors below.
What the Electrician Actually Does
An EICR combines a visual inspection with live and dead testing. The electrician checks the condition of the consumer unit, tests every circuit, checks earthing and bonding, inspects sockets and switches, and tests RCDs where fitted. Every step is documented, which is part of why the process takes longer than a quick visual glance.
What Speeds the Inspection Up
- Clearing furniture and belongings away from sockets and the consumer unit in advance
- Making sure someone is home to provide access to every room, including lofts and outbuildings
- Having your previous EICR and any remedial certificates ready to show the electrician
- Labelling or knowing the location of your consumer unit and any additional distribution boards
What Slows the Inspection Down
- A painted-over or hard-to-reach consumer unit
- Furniture blocking sockets or switches
- Multiple consumer units in converted properties or HMOs
- Older wiring that needs more careful assessment
- Missing keys or access to outbuildings, garages, or lofts
How Long Until You Get the Report?
The inspection itself is only part of the timeline. Most electricians issue the written EICR within 24 to 72 hours after the visit, though some same-day services exist for an added fee. If the result is unsatisfactory, remember that the 28-day clock for remedial work starts from the date of the inspection, not the date you receive the written report. See our guide on what happens if you fail an EICR for the full process.
Booking Enough Time
When booking, tell the electrician your property type and roughly how many bedrooms, bathrooms, and outbuildings it has. This helps them block out a realistic slot rather than underestimating and having to return for a second visit, which can delay your compliance timeline unnecessarily.
Frequently Asked Questions
How long does an EICR take for a flat?
Usually one to two hours for a studio or one-bedroom flat.
How long does an EICR take for a house?
A standard two to three-bedroom house typically takes two to four hours. Larger houses can take four to six hours.
How long after an EICR do you get the report?
Most electricians issue the written report within 24 to 72 hours of the inspection.
Does a bigger house always take longer?

Can I speed up my EICR appointment?
Yes. Clearing access to sockets and the consumer unit, and having previous certificates ready, are the biggest time savers.
