Who is this for?

Homeowners upgrading from battery-only alarms, landlords meeting legal obligations for rental properties, and anyone renovating or extending a home.

Signs you need this

  • Your current alarms are battery-only and older than 10 years
  • You are letting a property and need interlinked alarms on each floor
  • You are renovating, extending, or converting a loft
  • A recent EICR or fire risk assessment flagged missing detection
  • You want the reassurance of kitchen heat detection without false alarms

What is included

  • Survey to work out the correct grade and category of system for your home
  • Supply and installation of mains-powered alarms with sealed battery backup
  • Interlinking so any alarm triggers all alarms, wired or radio-linked
  • Placement in line with BS 5839-6, usually landings, hallways, and kitchens
  • Commissioning test and BS 5839-6 certificate on completion

How it works

  1. 1Tell us how many floors and rooms, and whether the property is a let.
  2. 2We recommend the right grade of system. Most London homes are Grade D1 or D2.
  3. 3Install takes a few hours to a full day depending on how many alarms and whether we use wired or radio interlink.
  4. 4Handover includes a test, a certificate, and the user manuals.

Certification on Completion

Systems are designed and installed to BS 5839-6, the current standard for fire detection in domestic premises. Alarms are supplied by leading UK manufacturers (Aico, Kidde, FireAngel) with a 10-year manufacturer warranty.

I recently had four ceiling lights changed in my flat in Pinner, and I couldn’t be happier with the service. The work was completed at a very reasonable cost, and he was extremely kind, courteous and helpful throughout. As an elderly customer, I particularly appreciated his patience, professionalism and excellent customer care. He was reliable, respectful and made the whole process very easy. I would thoroughly recommend his services to anyone looking for a friendly, trustworthy and reasonably priced electrician.
