How to protect yourself from carbon monoxide
- 1. Our advice is clear:
- The first and best thing you can do to minimise the risk that your gas appliances produce CO is to ensure that they are safety checked annually by a suitably competent and qualified Gas Safe registered engineer. If your boiler plan covers an annual service and you haven’t had one yet in this plan year you can find the contact number to arrange this in 'myaccount'
- An audible CO alarm will activate in the presence of CO. It’s a good second line of defence, but can only tell you when something has already gone wrong
- Make sure any alarm you buy is marked to EN 50291 and has the British Standards Kitemark
- 2. Carbon monoxide alarm — A good second line of defence
Modern CO alarms are similar in design to smoke alarms (which do not detect CO) and can be purchased from around £15 at many major retail outlets including DIY stores and supermarkets. We do not recommend the use of 'black spot detector' warning strips — they are too easy to miss and won't alert you if you have a CO leak when you're asleep.
It’s advisable to fit an alarm in every room with a gas appliance, and when installing and siting the alarm make sure you refer to the manufacturer’s instructions. Typically, audible CO alarms have a battery life of up to 5 years. If you’re unsure which alarm to get, you can ask a Gas Safe registered engineer for advice.
