Why fit a gas or CO detector?

Carbon monoxide has no colour, taste or smell, and a gas leak can easily go unnoticed, especially while you’re asleep. A detector checks the air all the time and sounds an alarm at the first sign of danger, so you have time to act.

Gas detector installation in London

Fitted, tested and explained before we leave

A Gas Safe registered engineer checks your gas appliances and the layout of the room, then fits each CO alarm or gas detector where it will work best, near the boiler, fire or cooker. We test every detector once it’s in and show you what the alarm sounds like and what to do if it goes off. Landlords in England must fit a CO alarm in any room with a fixed combustion appliance, such as a gas boiler or fire (gas cookers don’t count). We can fit alarms during your annual gas safety check.

CO alarm and detector care

A detector only protects you if it works. Test it regularly, replace the batteries when needed and replace the whole unit by the date shown on it.

Jennings can look after this for you. Our engineers test your alarms, change batteries, replace units that have reached the end of their life and check each one is in the right place. If you think you already have a leak, our gas leak detection service can find it.
