This is vital to prevent the buildup of dangerous gases within your home such as carbon monoxide. Carbon monoxide is a deadly gas that can cause poisoning when it accumulates. Your engineer will check it regularly when they are on the property.
They will also check flues and chimneys to make sure they are free of obstructions, sealed properly and able to release gases in a consistent manner.

The CP12 also identifies whether the appliances being tested are sealed or open vented. It will also record the gas pressure supply and if the cistern for expansion and feed has an open valve that is operating properly. The engineer will also test the efficiency of the combustion process and determine whether the appliance is displaying signs of carbon monoxide.

The natural draft generated by the flue is vital to the functioning of these types of appliances, since the gas has to be able to escape from the inside of the appliance and not be recirculated within the structure. A gas safety engineer will examine the exterior and interior of a flue in order to ensure that it is properly sealed and that there are no obstructions and that a natural draft is being created.
A qualified engineer will also examine the valves and pipes that connect to every gas appliance connected to the flues. If these connections do not meet the accepted standards, there could be dangerous gas leaks that aren't discovered. It is also important to ensure that the gas supply and outlet of each appliance are clean to prevent any buildups of carbon monoxide to form.
A certified engineer will record any faults or defects with the gas installation as well as its appliances and appliances on a certificate of gas safety. When they return to the house, they can fix the problems and bring the house up to the standard. Landlords are legally required to obtain an gas safety certificate for every property they lease out, so that they can be sure that their tenants are protected from any heating or gas-related accident.

If an appliance is found to leak carbon monoxide, the engineer could suggest replacing it right away.
The engineer will not only examine the appliances, but also the flues. He will make sure that there aren't any obstructions in the flues, and that the gases can be released frequently. This attention to detail is essential as CO poisoning can occur if the hazardous gas is not eliminated from the premises.

The document includes the name and registration of the engineer who performed the inspection and the address at which the tests were carried out.
The gas engineer will make sure that the appliances in a property are safe to use and that they comply with current regulations. They will look for leaks, ensure that there is sufficient ventilation, measure gas pressure, etc. They will also inspect the flues to ensure that combustible gases are being properly expelled and test the performance of the appliance including the efficiency of combustion.
