What Electrical Work Needs an Electrician? Part P FAQs

Part P of the Building Regulations covers electrical safety in dwellings. Notifiable work must either be carried out by a registered competent person who self-certifies it, or be notified to building control in advance, which is slower and usually more expensive.

Notifiable work includes: new circuits (kitchen ring finals, cooker circuits, EV charger supplies, garden or garage supplies), consumer unit replacement, and any addition or alteration to circuits in special locations such as bathrooms, shower rooms and swimming pool areas.

Non-notifiable work includes replacing an existing accessory like for like, replacing a damaged cable on a like-for-like basis, and adding to an existing circuit outside a special location. Non-notifiable does not mean unregulated: the work still has to comply with BS 7671 and should be tested.

The practical reason to use a registered electrician is documentation. When you sell or remortgage, conveyancers ask for certificates for recent electrical work. Uncertified work often leads to retentions, indemnity policies or a demand for a fresh inspection.

For landlords, uncertified DIY alterations are one of the most common reasons an EICR comes back unsatisfactory with C2 observations.
