Electrician needed -Replace 4 hardwired interlinked smoke alarms
£250
Surrey Quays, Greater London, SE16
5th Aug 2026
I need 4 mains-wired, interlinked optical smoke alarms replaced on a like-for-like basis. All 4 were installed on the same day, approximately 10years ago. 2 of the 4 are now beeping (3 beeps every 4 hours), which I understand indicates end-of-life on these units. The other 2 haven’t started beeping yet but are the same age, so I’d like all 4 replaced together in one visit. What’s needed: • Safely isolate power, remove the 4 existing units, and dispose of them properly • Supply and install 4 new mains-powered, interlinked optical smoke alarms in the same locations • Test all units individually and confirm the interlink function works across all 4 • Must be a qualified/registered electrician (e.g. NICEIC or equivalent) as this is mains electrical work
Great experience working with Juan. Very thorough, takes pride in his work and went the extra mile. Would work with him again.
Water coming through smoke alarm, need to isolate smoke alarm

Stockwell, Greater London
29th Jul 2026
Emptying the bath last night tripped the electrics. The mains-powered smoke alarm would not switch off. There is not a separate fuse for the smoke alarm. We need to isolate the smoke alarm to prevent electric fire. Will also need a plumber to check for leaks.
Very quick and professional
