Did you know that your domestic wiring should be inspected and tested every 10 years?

A dwelling should have it’s electrical installation checked whenever there is a change of occupier.

A complete test and inspection of an average domestic installation takes around 1 day to complete. At the end of the inspection you are given a Periodic Inspection form which will outline exactly the condition of the installation and inform you of any improvements required. This is an extremely useful thing to have if you are thinking of moving house.

The regulations state that anyone completing an inspection and test of an installation should be ‘competent’.

Holders of the C&G2391 certificate have completed a 5 day course with a practical and written exam. What better way to prove competence!

All test meters have to be calibrated once a year to check accuracy. Each meter will have a calibration certificate which you have every right to see.

The Periodic Inspection form duly completed and signed by a competent person is your proof that a dwellings electrical systems have been checked and comply with the electrical regulations in force when the installation was completed. As long as an installation is safe there is no requirement to update it to the latest edition.

Ok lets get something straight right from the outset!
There is no such thing as a landlord certificate!

That’s got that out the way then. There is a requirement that rented property is inspected and tested though. The Landlord and Tenant Act 1985 specifically states that the landlord is to ensure the electrical installation is safe when a tenancy begins and that it is maintained in a safe condition throughout the tenancy. Also as stated earlier all dwellings should be checked when there is a change of occupier.
Basically before letting a property you should have a full inspection and test of the electrical installation carried out by a competent person. You will be given a Periodic inspection form at the end of the inspection outlining the condition and any work required to bring the installation up to scratch. This should be repeated every 10 years to comply with the regulations. Then at every change of tenancy you should have the installation checked to ensure it is still in the same condition as when previously inspected.
For more details please ring me and I will be happy to discuss your compliance.
Be aware that if you are considering changing your consumer unit or fuse box that a full inspection and test of the connected electrical wiring will have to be carried out. As the consumer unit is the origin of the connected circuits a certificate will have to be issued for the entire installation. This means that any faults found that would compromise the electrical safety of the installation would have to be rectified.
You will be issued with a Periodic Inspection form with a Schedule of Inspections and a Schedule of Test Results.  On this form any deviation or items that do not meet the current edition of BS 7671 would be highlighted with methods of correcting if required.
As mentioned before this does not mean you have to have the installation renewed if it does not comply. If your cables conductor sheaths are red and black but the installation is sound and safe it will be noted on the inspection that the colours do not comply but the installation is good.
Even if your installation does not comply or could be dangerous we are not allowed to disconnect your supply. We can only bring the matter to your attention and urge you to have the installation made safe. Of course we would note on the inspection form any faults and rectification required.
