If you live in a property that has a boiler flue which cannot be inspected because it is hidden behind a wall or ceiling, you need to install an inspection hatch. Gas engineers need to be able to see the flue which take fumes away from the boiler as part of essential safety checks. A flue in poor condition, combined with a boiler that is not working properly, could put you and your family in danger from carbon monoxide poisoning, which can cause death or serious injury.
If your boiler is situated on an outside wall, it is unlikely you have this type of flue. Alternatively, if your engineer can see all of the flue, you will not need to take any further action.If you do have a boiler where all, or part of, the flue cannot be seen, you, or your landlord, will need to arrange for inspection hatches to be fitted. This does not mean, however, that your flue system is suddenly unsafe. As long as the boiler passes a series of safety checks – including having audible carbon monoxide alarms fitted it can be used normally for the time being.
Carbon monoxide alarms are not an alternative to being able to see the flue and you will still need to have hatches fitted. It is recommended, that hatches are fitted as soon as you are able to do so. From 1 January 2013, any registered gas engineer will turn off the gas supply to the boiler until hatches have been fitted in appropriate places.
