If you are booking an Electrical Installation Condition Report, one of the first questions is simple: how long does an EICR take? Most domestic EICRs take around 1.5 to 5 hours, depending on the property size, number of circuits, age of the installation, access and condition. A very small, straightforward flat may be quicker, while larger houses, HMOs, older properties and commercial premises usually take longer.
A small flat will usually take less time than a larger house. A modern property with a tidy electrical installation is often quicker than an older property with outdated wiring, poor access, or signs of damage. That is why there is no single fixed answer for every property.
This guide explains typical EICR inspection time, what affects the duration, how long it takes to receive the report, and what landlords, homeowners, buyers, and agents should expect from the process. If you are not fully sure what the inspection covers, read our guide on what is an EICR certificate before booking.

Key Takeaways
- Most domestic EICRs take 45–90 minutes for smaller properties and 1.5 to 4 hours for larger homes.
- The biggest time factors are the number of circuits, access to the consumer unit/sockets, and the age/condition of the wiring.
- Unlabelled circuits, restricted access (locked rooms/furniture), and faults needing investigation are the most common reasons an EICR takes longer.
- Commercial EICRs usually take longer because premises often have multiple distribution boards and more complex electrical systems.
- You can speed things up by making the consumer unit accessible, ensuring all rooms are available, and sharing any previous EICR if you have one.

Quick Answer: How Long Does an EICR Take?
The most accurate answer is always based on the actual property, but these timings are a useful guide for most domestic bookings.
| Property type | Typical EICR time |
|---|---|
| 1 bedroom flat | 1.5 to 2.5 hours |
| 2 bedroom flat | 2 to 3 hours |
| 2 bedroom house | 2 to 4 hours |
| 3 bedroom house | 3 to 5 hours |
| 4 bedroom house | 4 to 6 hours |
| Larger house, HMO or more complex property | Varies depending on circuits, access and condition |
So, if you are asking how long does an EICR take for a 3 bedroom house, the answer is usually around 3 to 5 hours. If you are asking how long does an EICR take for a 2 bedroom flat, it is usually around 2 to 3 hours.
These are not random numbers. They reflect the fact that the electrician is not just walking around with a clipboard. A proper EICR includes inspection, testing, recording observations, checking safety components, and producing a formal report. If you want a more detailed step-by-step explanation of the inspection itself, see our guide to the EICR test procedure.
How Long Does an Electrical Installation Condition Report Take?
An electrical installation condition report usually takes a few hours for a standard domestic property. The inspection is designed to assess the condition of the fixed electrical installation, so the electrician needs enough time to inspect, test and record the findings properly.
A straightforward flat with good access is usually quicker than an older house with more circuits, extensions, outbuildings, older fuse boards or signs of wear. Commercial premises can take much longer because they often have more boards, more circuits and a more complex installation overall.
How Long Does an EICR Check Take?
If you are wondering how long an EICR check takes, the answer depends on the size, age and condition of the property, as well as the number of circuits that need to be inspected and tested. In most domestic properties, an EICR inspection is usually measured in hours rather than minutes. Smaller flats may take less time, while larger houses or properties with older electrical installations can take longer.
An EICR check is far more than a basic visual look around the property. A proper EICR test includes a detailed inspection of the electrical installation, testing of key circuits and components, and the preparation of a written report outlining any observations, defects or safety concerns. This is why a genuine Electrical Installation Condition Report should never be rushed.
The overall time needed for an EICR inspection can also be affected by access to sockets, consumer units, fixed wiring and other parts of the installation. If issues are found during testing, extra time may be required to complete the assessment properly. In short, a professional EICR check takes time because it is designed to provide an accurate picture of the safety and condition of the electrical system.
How to Help the EICR Finish Faster
| What to Prepare | Why It Helps |
|---|
| Clear access to the consumer unit | Allows the electrician to start inspection and testing without delays |
| Make sockets and switches accessible | Reduces time spent moving furniture or dealing with blocked points |
| Ensure all rooms are accessible | Avoids limitations and possible return visits |
| Share the previous EICR if available | Helps the inspector understand past observations and installation history |
| Confirm tenant or occupier access | Prevents missed appointments and restricted inspection areas |
| Tell the electrician about known faults | Helps identify areas that may need closer inspection |
| For commercial premises, agree shutdown windows | Reduces disruption and avoids incomplete testing |
What Affects How Long an EICR Takes?
Several factors affect EICR duration.
- Property size: Larger properties usually take longer because there are more rooms, more sockets, more lighting points and more circuits to inspect and test.
- Number of circuits: Two properties of a similar size can still take different amounts of time. A property with additional circuits for showers, cookers, outbuildings, electric heating or other installations will usually take longer than a simpler property.
- Age of the installation: Older installations often need more careful checking. There may be outdated components, earlier repairs, mixed wiring ages or signs of previous electrical alterations that require closer inspection.
- Ease of access: If the electrician cannot easily access the consumer unit, sockets, switches or key parts of the installation, the inspection will naturally take longer. Furniture, stored items, locked rooms and poor preparation can all slow the process down.
- Condition of the electrics: If the installation shows signs of wear, damage, overheating, poor workmanship or missing protective measures, more time may be needed to inspect and record everything correctly.
- Occupied or vacant property: An empty property is usually easier to inspect than an occupied one. In lived-in properties, furniture, personal belongings and access restrictions often make the inspection slower.
What Is the EICR Process?
A proper EICR usually includes the following stages:
Initial review
The electrician will review the installation, identify the consumer unit or distribution board, and assess the general layout of the property.
Visual inspection
They will inspect visible electrical components for signs of wear, damage, poor workmanship, unsafe alterations, or missing protective measures.
Testing
The installation is tested to assess the condition of the circuits and safety arrangements. This is the part that takes time and is one reason a proper EICR cannot be rushed.
Recording observations
Any issues found are recorded in the report. These may range from minor recommendations to more serious faults.
Report preparation
The results are compiled into the EICR so the client has a formal record of the condition of the installation.
What Does an EICR Involve?
An EICR involves a detailed inspection and test of the fixed electrical installation within a property. This includes the consumer unit, protective devices, accessible wiring, earthing or bonding and the overall condition of the electrical circuits.
The aim of an EICR is to identify damage, deterioration, defects, dangerous conditions and any areas that do not meet current safety standards 18th Edition of the IET Wiring Regulations (BS 7671). Once the inspection and testing are complete, the findings are recorded in a formal written report.
This is why many people searching what an EICR involves also want to know how long an EICR takes. A proper EICR is a thorough electrical safety inspection, not a quick formality. If you want to see what the final document looks like, view our EICR report example.
How Long Does It Take to Get an EICR Certificate?
Another common question is how long does it take to get an EICR certificate after the inspection has been completed.
In many cases, the report is issued after the site visit once the results have been reviewed and written up. Straightforward properties are usually quicker to turn around than larger or more complex jobs with several observations. If the installation is older or multiple issues are found, the reporting process can take longer because the findings still need to be recorded properly.
What matters most is accuracy. A clear, properly prepared report is far more useful than a rushed document that misses important issues.
Homebuyer Electrical Report: How Long Does It Take?
A homebuyer’s electrical report is often used informally to describe an EICR when the aim is to assess the condition of the fixed electrical installation. In most cases, the correct inspection is an EICR, which checks the safety and condition of the property’s electrical system.
The time required for an EICR will usually depend on the size, layout and overall condition of the property. For most homes, the inspection is typically completed within a few hours rather than in a short visit.
If you are buying a property and want a clear assessment of the electrics, it is important to arrange the correct inspection. Booking an EICR helps ensure you receive a proper evaluation of the fixed electrical installation and a formal written report.
Does the Power Need to Be Turned Off During an EICR?
There is often some disruption during an EICR because parts of the installation may need to be isolated while testing is carried out safely. This does not always mean the power is off for the full appointment, but some interruption should be expected.
For landlords, agents and homeowners, it helps to plan ahead and make sure occupants understand that the inspection may temporarily affect power to some circuits.
Why One EICR Takes Longer Than Another
No two properties are exactly the same. A modern two-bedroom flat with a well-maintained electrical installation will usually take less time to inspect than an older three-bedroom house with extensions, restricted access and a history of electrical alterations.
For that reason, the best answer to how long an EICR takes is a realistic time range rather than a single fixed figure. The time required for an EICR should reflect the size, condition and overall complexity of the property, allowing the inspection and testing to be carried out properly.
If the EICR Finds Problems, Does the Inspection Take Longer?
It can do. If faults, damage or unsafe conditions are identified, the electrician may need extra time to inspect and record them correctly. That does not mean the remedial work will always be completed on the same visit, but it can extend the inspection and reporting time.
Properties with more issues generally require more detailed reporting than properties with fewer observations. If faults are found, they must be recorded with the correct classification, so read our guide on EICR codes to understand how observations are graded.
How Long Does a Commercial EICR Take?
A commercial EICR usually takes longer than a domestic EICR because commercial premises often have more circuits, multiple distribution boards, three-phase supplies, plant rooms, restricted areas, business-critical equipment and access requirements.
A small shop or office may be completed faster than a large warehouse, restaurant, school, care setting or multi-floor commercial building. In many commercial premises, the inspection may need to be planned around opening hours, staff access, tenant access or agreed shutdown windows.
For commercial properties, the correct inspection time should be based on the size, complexity and risk of the installation, not a fixed promise. The next inspection interval is normally recommended by the competent person carrying out the inspection and testing, based on the type of installation, its use, maintenance history and external influences. For business premises, inspection time and frequency should be planned around the property type, risk and usage, as explained in our guide on commercial property EICR requirements.
How Long Does an EICR Take for Landlords?
For landlords, the key point is that an EICR should be allowed enough time to be carried out properly. It is not something that should be rushed just to get a report in hand. A proper inspection gives you a written record of the condition of the installation and helps identify any issues that need attention.
If the property is tenanted, it is also worth allowing extra time for access, coordination and any disruption caused during testing. For landlord rules and compliance duties, read our guide on whether an electrical safety certificate is a legal requirement for landlords.
How Long Does an EICR Take for Homeowners?
For homeowners, the time usually depends on the size and condition of the property. Smaller properties are often quicker, while older homes or houses with more circuits will usually take longer.
The benefit of allowing enough time is that the report gives a clearer picture of the condition of the electrics and whether any work is needed to improve safety.
Final Answer: How Long Does an EICR Take?
For most domestic properties, an EICR usually takes around 2 to 5 hours. Smaller flats are often quicker, while larger houses or older installations usually take longer. The exact time depends on the property size, number of circuits, ease of access, age of the installation and what is found during inspection and testing.
