Whether you’re a landlord preparing your rental property, a homeowner checking electrical safety, or a business needing compliance, timing matters. Here’s everything you need to know about how long an EICR takes—along with tips to make the process as smooth as possible.
1. Typical Duration for an EICR Test
The time it takes to complete an EICR depends on the size and complexity of the property, but here’s a general guide:
| Property Type |
Estimated Time |
| 1-bedroom flat |
1.5 to 2 hours |
| 2-3 bedroom house |
2 to 3.5 hours |
| 4+ bedroom house |
3.5 to 5 hours |
| Small commercial unit |
3 to 5 hours |
| Larger business premises |
1 day or more |
At RCD Electrical, we aim to complete all EICRs efficiently but thoroughly, never rushing the process. Your safety comes first.
2. What Affects the Duration of an EICR?
Several key factors can influence the length of time your EICR takes:
a) Number of Circuits
The more electrical circuits in your consumer unit (fuse board), the longer it takes to test each one individually.
b) Access and Layout
Our electricians need access to sockets, switches, and the main electrical board. If furniture or locked rooms block access, this may slow us down.
c) Age and Condition of the Installation
Older wiring may require extra investigation. Likewise, if issues arise mid-test, extra time is needed to ensure accurate results.
d) Type of Property Use
Domestic properties are typically faster than commercial or industrial buildings due to fewer systems and wiring routes.
3. What Happens During an EICR Test?
Here’s what we check when we visit your property:
-
Fuse board inspection
-
Circuit continuity and insulation resistance tests
-
Polarity and earthing tests
-
Visual inspection of sockets, lights, switches, etc.
-
Identification of any electrical hazards
Each test is methodical and recorded to produce your certified report. Our NICEIC-qualified engineers follow strict procedures to ensure every box is ticked.
4. How to Prepare for an EICR to Save Time
To help us complete your EICR efficiently, you can take a few steps before we arrive:
Ensure all rooms are accessible
Unplug devices if possible
Notify us of any faulty switches or past issues
Provide access to the fuse board
At RCD Electrical, we always contact you beforehand to confirm access requirements and answer any questions so there are no surprises on the day.
5. What Happens After the EICR is Done?
Once the inspection is complete, we’ll provide you with a detailed written report, usually within 24 to 48 hours.
If your report includes a C1 or C2 code (immediate danger or potentially dangerous), we can quote and carry out remedial work promptly. Our aim is to help you become fully compliant without delays.
