Electrical Safety Inspections: What’s Checked, Costs, & UK Rules
These days, most people understand why electrical safety inspections matter, but many still wonder what actually happens during one. Over time, wiring and electrical systems naturally wear down, which is why regular testing is recommended to make sure everything remains safe to use.
They are commonly referred to as periodic checks or EICRs and are carried out to detect faults before they develop into dangerous conditions. PMC experts in this guide define what electrical safety inspection entails and what to expect throughout the process.
What is an Electrical Safety Inspection?
It is an inspection of the wiring, circuits, and electrical components of a property which are fixed. An electrician who is qualified inspects the installation as per BS 7671 UK wiring regulations and provides a report of either satisfactory or unsatisfactory. It will be based on the degree of safety and the defect that occurs.
When Do You Need an Electrical Safety Inspection in the UK?
The inspection of electrical safety is conducted periodically or every time the condition changes. They will assist in assuring the safety of the electrical installation to be safely used in the future, as well as to comply with the current safety standards. Although some of the inspections are by law mandatory, some are highly advised as a good practice in property maintenance.
Legal Requirement for England Landlords
Landlords in England have the duty of ensuring that the electrical installations within their rented premises are inspected and tested by a qualified individual at least once every five years. Once the inspection has been done, you are supposed to receive an EICR, giving one copy to the existing tenants, and holding the report on record until the next time of inspection. In case the report reveals unsafe faults, remedial work must be accomplished within the stipulated period of time to be in compliance.
Recommended Intervals for Homeowners
For landlords, electrical safety inspections are not always mandatory, but they are widely recommended to maintain safety. As a general guide:
- Every 10 years for owner-occupied properties
- Every 5 years for rented homes
- Before buying a property or selling a property
- After major renovations, damage, or long periods without testing
What does an Electrical Safety Check involve?
An electrical safety check focuses on the fixed wiring installation of a property. The electrician follows a structured process that combines visual checks with technical testing to confirm the system is safe and compliant.
Fixed Wire Installations
An EICR looks at the permanent electrical parts of a property, including:
- Consumer unit (fuse box)
- Wiring and circuits
- Plug sockets and switches
- Light fittings
- Earthing and bonding
- Protective devices such as RCDs
The Inspection Process
Visual inspection
Before any testing starts, the electrician carries out a basic safety review:
- Signs of overheating or damage
- Unsafe DIY work or loose fittings
- Exposed wiring or outdated components
- Condition of sockets, switches, and accessories
Dead testing
These tests are done with the power switched off to identify hidden wiring faults:
- Continuity testing to check connections
- Insulation resistance to confirm cables are protected
- Ring circuit checks to ensure correct wiring and polarity
Live testing
Once safe, the system is powered to confirm that protective devices work correctly:
- Polarity testing to verify correct connections
- Earth fault loop impedance testing
- RCD testing to ensure the system disconnects during a fault
Your EICR report is issued
After testing, you receive an Electrical Installation Condition Report showing:
- Satisfactory or unsatisfactory result
- Any safety observations or fault codes
- Recommendations or required remedial work
EICR Codes Explained (C1, C2, C3, FI)
Once the inspection has been carried out, any questions that were identified will be recorded on the EICR by standard observation codes. These codes indicate the severity of a fault and the need to act or not act.
- C1: Immediate risk of injury or fire. The electrician will normally ensure that the installation is made safe immediately, and immediate repair is needed.
- C2: A defect which might be dangerous if not solved. Immediately, remedial work must be made.
- C3: Not hazardous, and an upgrade of the installation would enhance the overall safety and enable the installation to be closer to the existing standards.
- FI: Something has been identified that needs additional testing before the condition of the system can be confirmed.
How Long Does an Electrical Safety Check Take?
The duration of the electrical safety inspection is primarily determined by the number of circuits, the property’s area, and the complexity of the installation. Electricians give about 30 minutes per circuit as a rough guide; hence, an average home inspection takes about 3 to 4 hours. The process can be delayed in the event that some faults are detected or access is restricted. Other factors that affect timing include:
- Size and layout of the property
- Age of the wiring and consumer unit
- Previous EICR availability
- Number of sockets, switches, and lighting points being tested
Electrical Safety Inspections Checklist
A little preparation before the visit makes the inspection smoother and avoids delays. Before the electrician arrives, you can double check:
- Make sure the consumer unit (fuse box) is accessible
- Clear access to sockets, switches, and light fittings
- Check that no wiring is hidden behind furniture
- Have your previous EICR ready if available
- Let occupants know that power may be switched off during testing
What Affects the Cost of Electrical Safety Inspections?
The price of an electrical safety inspection is usually based on how much testing is required rather than just the size of the property. Electricians often calculate costs around the number of circuits, as each one needs to be checked individually during an EICR.
- Number of circuits on the consumer unit
- Type of property (flat, house, or commercial premises)
- Ease of access to wiring and accessories
- Age and condition of the electrical installation
- Urgent bookings, evenings, or weekend appointments
- Whether remedial work is needed after the inspection
Electrical safety inspection prices vary across the UK, but most quotes follow similar market averages. Electrician rates and EICR pricing look like this:
| Electrician rates | Cost + VAT (Range low – high) | Average cost |
| Electrician (per hour) | £40-£70 | £55 |
| Electrician (per day) | £250-£500 | £400 |
| EICR (domestic) | £100-£250 | £200 |
| Commercial EICR | £30-£50 per circuit | £40 per circuit |
Landlord Obligations After the Inspection
Once an EICR is complete, landlords have clear responsibilities to follow. The EICR is not just a report for your records. It forms part of your legal duty to keep the property safe and compliant. After receiving the EICR, landlords must:
- Obtain and keep a copy of the Electrical Installation Condition Report until the next inspection is due
- Provide the report to existing tenants within 28 days of the inspection
- Give a copy to new tenants before they move into the property
- Supply the report to the local authority if requested in writing
- Arrange remedial work promptly if the report is marked unsatisfactory
In the event of the EICR comprising C1, C2 or FI observations, a landlord must make sure that the necessary repairs or further investigation are done within the necessary time limit, which is 28 days. A copy of the work done should then be maintained with the original report to ensure that compliance has been maintained.
What’s the Difference Between an EICR and an Electrical Installation Certificate?
Both of these terms relate to electrical safety, but they have different purposes. An EICR is used to assess the status of a pre-existing electrical installation, and an Electrical Installation Certificate is used to confirm new electrical work is properly installed and compliant with the current standards.
| Feature | EICR (Electrical Installation Condition Report) | Electrical Installation Certificate (EIC) |
| Purpose | Assesses the safety and condition of existing wiring | Confirms new installation or major electrical work is compliant |
| When it’s used | Periodic inspections, landlord compliance, and property checks | After a new installation, rewire, or significant alteration |
| Legal context | Required for landlords at least every 5 years in England | Issued when new electrical work is completed |
| What it includes | Testing results, fault codes (C1, C2, C3, FI), safety observations | Details of the work carried out, design, installation, and testing confirmation |
| Outcome | Marked satisfactory or unsatisfactory | Certifies the installation meets current regulations |
| Focus | Ongoing safety and maintenance | Sign-off of newly installed electrical systems |
