Smoke Detector Installation in London & Surrey
Smoke detectors save lives. TW Electrical installs mains-wired, interlinked smoke detector systems in domestic properties across London and Surrey. We specialise in residential installations — from a single smoke alarm upgrade in a Twickenham flat to a full interlinked system throughout a family home in Surrey. All our installations use quality, approved detectors and are carried out by our NAPIT-certified electricians. Unlike battery-only alarms, mains-wired interlinked detectors activate simultaneously throughout the property when any one detector is triggered, giving occupants maximum warning time. Please note: we currently focus on domestic smoke detector installations and do not carry out commercial fire alarm system maintenance or installation.
