by Part P of the Electrical regs.

When did this happen then????

It didn't. Domestic electrical work outdoors (outbuildings, in gardens
and outdoor lighting, etc.) is still in-scope of Part P - i.e. it must
be safe in respect of electric shock and fire risks.

What changed in 2013 is that the range of work deemed to be notifiable
was significantly reduced. Only the following are notifiable now:

- installation of a new circuit (presumably meaning either a
distribution circuit (submain) or a final circuit;

- the replacement of a consumer unit (but not the installation of a new
one, in a new shed, for instance...)

- any work within the zones in a bath/shower room, or in a swimming pool
or sauna.
