What to do if you suspect CO poisoning
Get fresh air immediately. Ventilate your house by opening doors and windows and turn off your gas appliances.
See your doctor immediately or go to hospital – let them know that you suspect CO poisoning. They can do a blood or breath test to check. In emergency circumstances call for an ambulance.
If you think there is an immediate danger, call the Gas Emergency Helpline on 0800 111 999.
Ask a Gas Safe registered engineer to inspect your gas appliances and flues to see if there is a dangerous problem.
The warning signs of a CO leak
Any of the following signs could indicate a CO leak in your home:
Flames of a lazy yellow or orange colour on your gas hob, rather than being a crisp blue;
Dark staining on/around appliances;
Pilot light that frequently blows out;
Increased condensation on windows.
Having your gas appliances serviced regularly can help to avoid issues with CO poisoning. Always use a Gas Safe Registered engineer to carry out any work on your gas appliances
The benefits of having a CO alarm
While there is no substitute for having your appliances serviced and checked regularly by a Gas Safe Registered Engineer, fitting an audible CO alarm in your property is a good second line of defence. Modern CO alarms are similar in design to smoke alarms and can be purchased from around £15 at many major retail outlets including DIY stores and supermarkets. You may wish to invest in a connected system like the Nest Protect which is a smoke and CO alarm. Ask us about installing your Nest Protect. Before purchasing any CO or smoke alarm, make sure it is marked to EN 50291 and has the British Standards Kitemark or another European approval organisation’s mark on it. Our advice is to fit an alarm in every room that has a gas appliance. When installing and siting the alarm please refer to the manufacturer’s instructions. Most audible CO alarms have a battery life of up to 5 years.
