Install replacement hard-wired smoke alarm (Ei3016) – North Finchley

£40

North Finchley, Greater London, N12

28th Nov 2025

I already have the replacement smoke alarm (model Ei3016). The old one is installed on a ceiling base plate and the wiring is already done. It started beeping and probably needs a battery replacement. I just need someone to safely disconnect the power, remove the old alarm, clip the new one in, and test it. Should be a quick job (5–10 minutes). Ceiling is easy to reach with a chair or small ladder. Please bring a voltage tester or be comfortable working with mains. North Finchley location. I prefer someone with electrician or maintenance experience, but a competent handyman is fine.
