Part P - Electrical Work
Responsibilities as a homeowner
Did you know that it is your responsibility to ensure that any electrical installation in your home is either completed by an electrician registered with a competent persons' scheme, or checked by one?
Under Part P of the building regulations, DIY work and electrical installation work carried out by non-registered trades perople should be checked and certified. As the property owner, you're ultimately responsible for ensuring electrical work complies with the rules.
The regulations do not stop you doing your own work or using an unregistered tradesperson, but you still need to make a Building Regulations Application or have a member of an electrical competent persons’ scheme check it and issue the notice and certificate.
It's easier and safer if you use an electrician registered with a government-authorised competent persons' scheme because then you may not need to put in an application to your local authority, as they're authorised to do this.
