What is Fixed Wire Testing?

To ensure your property is electrically safe, an examination of fixed electrical installations is required. This type of fixed wire testing is often referred to as EICR (Electrical Installation Condition Report) and is particularly important in rental and commercial properties.

During a fixed wiring test one of our expert inspectors will check the fixed electrical system within a building to identify if there is any damaged wiring or faulty sockets and switches. An EICR certificate will be provided if no remedial works are required.

Had requirement for an urgent electrical check up. Initial and subsequent contact with the Hexo admin team was good. Needs dealt with efficiently and politely. Experience was very good.
Me and my flatmate both have full-time jobs which made arranging access slightly tricky. The electrician met me outside the flat in the morning so I could leave my keys with him for the day. He completed the works and left my keys in the flat, no trouble.

The Importance of Fixed Electrical Testing

Faulty electrics are one of the leading causes of fires within both commercial and residential buildings.

To protect your home and yourselves, it is vitally important to maintain your electrical systems and ensure that regular fixed wire tests are carried out.

For landlords of rental properties, it is also a legal requirement to obtain an EICR. Failure to do so results in fines of up to £30,000. Visit our landlord’s page to get a quick and easy quote for a landlord’s certificate. Commercial properties also need to follow legal guidelines to ensure the property’s electrical safety.

What Happens During a Fixed Wire Inspection?

Our inspectors are highly experienced and will give an in-depth inspection of  each of the electrical installations at your property using the latest electrical testing equipment and accessories.

The electrical installations that will be tested during the fixed wire test include power sockets, lights, distribution boards, main panels, air conditioning and more.

Once the inspection is complete, you will be provided with an EICR certificate showing that your electrical installations have passed and are safe to use or, if the test result is unsatisfactory, you will be given a comprehensive coded observation for each and these will be shown on your EICR certificate. One of our experts will also provide a quotation to repair the defects and give advice on your options regarding the repair.

Fixed electrical testing does not include testing electrical appliances that are plugged in. This type of testing is called PAT (Portable Appliance Test) which is a service we are also happy to provide, usually for rental and commercial properties.

How Often Should Fixed Wire Testing Be Carried Out?

For residential homes, It’s advised that fixed wiring inspections should be carried out regularly. This is quite vague guidance so we’d say that unless your property is very old or you’ve noticed tell-tale signs of electrical faults such as flickering lights or faulty switches you only need to get the fixed wiring tested every 10 years. 

However, there are laws in place for commercial and rental properties that advise a fixed wire test needs to be done more regularly, every 5 years for rentals and less for commercial. See our commercial EICR page to find out more on commercial fixed wire testing and read our blog on a Landlord’s Guide To Electrical Safety.

Speak to one of our friendly team if you’re unsure on whether your property is due a fixed wiring test.

What Happens If Your Fixed Wire Test Fails?

If your fixed wiring fails its electrical testing your EICR certificate will show where it failed using four different types of classification codes. These are:

  • Code 1 (C1): Danger present. Risk of injury. Immediate remedial action required. These installations must be made safe immediately.
  • Code 2 (C2): Potentially dangerous. Urgent remedial action required. These installations must be made safe as soon as possible.
  • Further Investigation (FI): Further investigation required without delay. The electrical inspector will need to return to investigate the issue further
  • Code 3 (C3): Improvement recommended. You do not need to get this fixed immediately.

A code C1, C2 or F1 will mean your EICR certificate will be marked as unsatisfactory. You will need to carry out remedial work to get any issues investigated and repaired.

One of our expert engineers will provide an itemised quotation for remedial works required.

After the repair works have been carried out, we will test your entire system again. This will ensure the maintenance has been completed successfully.

What Are The Benefits of Fixed Wire Testing?


Did you know that the legislation regarding EICR reports has recently changed? Keeping up to date with amendments to the electrical regulations is important for well-performing safe installations; we will advise you of how compliant your installation is and recommend that if it is not fully compliant we carry out upgrades to make the installation fully compliant with the latest regulations and amendments.

It is not mandatory to be fully compliant with the latest regulations, but the installation must be deemed Satisfactory as a minimum. 


According to government statistics, outdated electrical installations and faulty electrical systems account for almost half of accidental UK house fires, and about four injuries a day. 

At Hexo Electrical Testing we can professionally check the safety of your electrical installation and repair any problems that may exist. Keeping your installation up to date will reduce the chances of an electrical dangerous occurrence.


It is increasingly common that insurance companies require a Satisfactory EICR for property insurance cover to be provided. You may see that regular domestic electrical testing is required as part of your policy agreement.

The insurance company will probably want to know that the condition of the electrical installation in the property is Satisfactory. Regularly keeping up to date with electrical regulations will prevent an unexpected major upgrade in the future.

Save Money

Never procrastinate – the repairs may cost you more! Keeping your electrical system compliant is the best way of saving – issues identified early may prevent further damage. Being prudent and keeping on top of electrical repairs will save you money in the long run. Prevention is usually better than cure.

Speed Up the Selling Process

If you’re selling your house, having an EICR certificate will give your buyer peace of mind and prevent any unexpected delays in the conveyancing process if a fixed wire inspection is requested.
