Detection & early warning

Smoke & heat alarms
in London.

Installation, replacement, additional alarms and testing for homes, landlords and managed properties.

Early warning that works together

Smoke and heat alarms are most effective when the right detector is fitted in the right location and the alarms can warn occupants throughout the property. We can assess existing devices, replace outdated or faulty units and add interlinked alarms where required.

For professional domestic fire and CO alarm systems, Aico is normally our first choice. We also consider established alternatives such as FireAngel, HiSPEC and Kidde where the required specification, compatibility and budget make them appropriate. The correct detector type, power supply, interlinking and positioning are agreed before installation.

Choosing a system? Read our Smoke, Heat & CO Alarm Guide for AVAG’s preferred brands, alternatives, interlinking and why correct system design matters as much as the alarm itself.

When to add or replace alarms

  • An alarm is missing from an important area.
  • Existing units are damaged, unreliable or beyond their recommended service life.
  • Alarms cannot be heard clearly throughout the property.
  • A property layout or use has changed.
  • You need a connected system for better whole-property warning.

Clear advice before installation

We check what is already fitted, discuss the property and recommend a suitable arrangement. After installation the alarms are tested and you receive simple guidance on regular user testing and maintenance.
