On your Gas Safety Certificate it will indicate if your certificate has failed by stating if either or all appliances are ‘Not Safe to use’ as a tick box. At the bottom of the gas certificate it will also state the failure findings with a code. Below you will find the definitions of what each code means.
‘Immediately Dangerous’ (ID)
An “immediately dangerous” installation is one which, if operated or left connected to a gas supply, is considered to be an immediate danger to life or property.
The installation will be disconnected, with your permission, and must not be used until the necessary work has been carried out to repair the defect(s). If you continue to use an immediately dangerous installation you could be putting you or your family’s lives in danger.
If you refuse the gas engineer permission to disconnect the installation or an individual appliance, they will report the situation to the Gas Emergency Service Provider (ESP). The ESP has legal powers to demand entry to make the situation safe or may disconnect the gas supply to the property.
‘At Risk’ (AR)
An “at risk” installation is where one or more recognised faults are present which could constitute a danger to life or property without further faults developing.
With your permission, the installation will be turned off and should not be used again until the fault has been repaired.
