Approval of domestic electrical work
All new domestic electrical work (for example in a house, flat or small commercial premise linked to domestic accommodation) must be designed and installed to comply with Part P (Electrical Safety) of the building regulations
These regulations make sure that electrical work in the home is carried out safely, but not all work needs to be approved.
When do I need approval for electrical work?
You must get approval for electrical work in:
- new dwelling houses and flats
- dwellings and business premises that share an electrical supply (e.g. shops and pubs)
- common access areas in flats (e.g. lobbies and laundry rooms)
- outbuildings (e.g. sheds, greenhouses and detached garages)
- external situations associated with the building (e.g. pond pumps and fixed lighting)
- new circuits in existing dwellings or new extensions
- existing domestic kitchens or bathrooms
You don't need approval for:
- domestic repairs, replacements or maintenance works
- extra power points, lighting points or other alterations to existing circuits (except for kitchens, bathrooms or outdoors)
How do I get approval for electrical work?
You can get approval for electrical work in one of two ways:
- using a Part P registered electrician
- submitting a building notice [90kb] to building control
Using a Part P registered electrician is the safest and cheapest option. Part P registered electricians are qualified to self-certify their own work so you won't have to apply to building control. You can find a Part P registered electrician in the Competent Persons Register.
If you use an unregistered electrician or other person to do your electrical work, you'll need to send a building notice to building control and pay £225. Our electrical contractors will check the work on behalf of building control. If they approve them, we'll issue you with a certificate.
