Fixed Wire Testing
It is the duty of every landlord to make sure that the property that they are renting is fit for the purpose for which it is intended. This includes the fixed electrical wiring.
The inspection reports are required at each change of tenancyand are to verify that the previous tenant has not damaged or changed the electrical system in any way.
If you are unfortunate enough to have a problem of an electrical nature while your property is being rented, you may be liable. It will be up to you to prove that the electrical installation was fit for purpose at the time of renting, and that the responsibility lies elsewhere.
Having an up to date electrical safety certificate will ensure that you can do this.
