Interesting point.

Only if you're also changing the consumer unit.

Since the revision of Part P in April the only electrical work that's notifiable is:

- installation of a new circuit,

- replacement of a consumer unit,

- additions or alterations within the zones of a bath/shower room,

- additions or alterations in a room containing a swimming pool or sauna heater (regardless of zones).
