Gas Certificate

Why do homeowners or landlords need a Gas Safety Record?

As a landlord, you are responsible for the gas safety of your tenants. You must ensure that all gas appliances are working correctly and safely.
Therefore, every rental property that has any sort of gas appliance, whether it be a gas boiler, gas hob or even a gas fire, requires a Gas Safety Certificate. These certificates can only be issued by a technician registered with the Gas Safe Register. All our engineers are registered with the Gas Safe Register.

The Gas Safe Register superseded CORGI (Council for Registered Gas Installers) as the sole legally recognised gas safety register in the UK on 1st April 2009. Gas Certificates are valid for a year from the date they are issued.

Some properties, mainly flats and apartments, have been built with boiler flues which cannot be inspected because they are hidden behind walls or ceilings. The boiler flues that this information relates to are connected to room-sealed fan assisted boilers only. Gas Safe registered engineers need to be able to see the flue − which take fumes away from the boiler − as part of essential safety checks whenever the boiler is worked on. Room sensing carbon monoxide alarms are not an alternative to being able to see the flue and you will still need to have inspection hatches fitted so that the flue system can be checked.

It is recommended that inspection hatches are fitted as soon as you are able to do so. From 1 January 2013, any Gas Safe registered engineer will classify the boiler as At Risk, this means that they will turn the boiler off, with your permission, and formally advise you not to use it until inspection hatches have been fitted in appropriate places
