Answers:    If you are electrical system a new circuit to the smoke detectors consequently yes you need to Certificate and Notify underneath Part "P" of the building regs.It would be an offence not to do so.
If you use the local lighting circuit next, as long as you do no work in a bathroom or kitchen or other notifiable nouns then you do not necessitate to notify but you must certify the work. with a Minor Works Certificate.
Remember that this system is in attendance to protect you as well as the tenant.
Use a Part "P" registered electrician if at all possible.


Check your local building codes.
if you hard lead them yes but have you thought of getting the type that plugs/screws into the wispy fitting?
try a company called rs 08457201201 or maplins.co.uk
