Smoke & CO Alarms
London & Surrey
Mains-wired and interlinked smoke and carbon monoxide alarms across London & Surrey. Compliant with current regulations and landlord requirements.
Smoke & CO Alarms in London & Surrey
Smoke and carbon monoxide alarms save lives. Current building regulations require smoke alarms on every floor of a property and carbon monoxide alarms in rooms with solid fuel appliances. For rental properties in London and Surrey, landlords are legally required to install working smoke alarms on every floor and CO alarms in rooms with solid fuel burning appliances. TW Electrical installs mains-wired, interlinked smoke and CO alarm systems that provide the highest level of protection. Unlike battery-operated alarms, mains-wired interlinked alarms activate simultaneously throughout the property when any one detector is triggered — giving occupants maximum warning time.
