Smoke and heat alarm installation in London
Smoke alarms, heat alarms and interlinked alarm systems, installed, connected and tested. For homes, landlords and businesses.

What this service covers
Working alarms give you time to react if there is a fire. We install and replace suitable smoke alarms, heat alarms and compatible interlinked alarm systems, including products from manufacturers such as Aico, and we connect and test them before we leave.
Alarm selection and positioning need to meet the requirements that apply to the property, and those can differ between homes, rented properties and business premises. Tell us about the building and we talk through what is needed. Interlinking, extra cabling and work to existing circuits can affect the price, and we explain that before we start.
When to fit or replace alarms
- Alarms that chirp, fail the test button or are past their replacement date
- You are moving into a property with no alarms or unknown ones
- You are a landlord or agent checking your alarm provision
- You want alarms linked so one sounds them all

Questions we hear about this service
What is the difference between a smoke alarm and a heat alarm?
A smoke alarm detects smoke. A heat alarm detects a rise in temperature and suits places like kitchens, where smoke or steam could cause false alarms.
What does interlinked mean?
Interlinked alarms are connected so that when one sounds, they all do, which helps in larger or multi-storey properties.
How much does it cost to replace a smoke alarm?
Prices start from £60 and are typically £60 to £120 for a straightforward single-alarm replacement, excluding the alarm.
Which alarms do I need as a landlord?
Rules differ between properties, so tell us about yours and we talk through what is needed and what we can fit.
