This is essential to avoid the build-up of dangerous gases in your home, such as carbon monoxide. Carbon monoxide is a deadly gas that can poison you if it builds up. Your engineer will check it frequently when they are on the property.
They will also check flues and chimneys to ensure they are clear of obstructions, sealed correctly and able to discharge gases consistently.

It includes the date of the inspection and the address of the property and the name and Gas Safe registration number of the person who conducted the inspection. It will also list the issues found and describe the steps to be taken to correct them.
The CP12 will also note whether appliances are sealed or open vented. The CP12 also notes the pressure in the gas supply, and whether or the expansion and feed cistern is fitted with a functioning ball valve. The engineer will also examine the combustion efficiency and whether the appliance is displaying signs of carbon monoxide.
While some landlords might believe that getting an official gas safety certificate is unnecessary, it is actually a legal requirement in the UK.

A gas safety engineer will check the exterior and interior flue to ensure it is sealed properly and free of obstructions.
A licensed engineer will examine the valves and pipes connecting to every gas appliance connected to the flues. If these connections do not meet the standards of the industry there may be risky leaks of gas that aren't discovered. To avoid carbon monoxide buildup it is crucial to keep the gas supply and outlet free of dust.
A certified engineer will record any flaws or defects in the gas installation along with its appliances and appliances on the certificate of gas safety. When they return to the home they can address the issues and bring the house up to standard. Landlords are required by law to get an gas safety certificate for each property that they rent out, so that they can be sure that their tenants are safe from any heating or gas-related accident.

The gas engineer will make sure that the appliances are safe to use and comply with current regulations. They will test for leaks, ensure that there is sufficient ventilation, test the gas pressure, and much more. They will also inspect flues in order to ensure that combustible gases are expelled safely and to check the performance of appliances including the efficiency of combustion.
If an appliance does not pass the test, it will be marked as immediately Dangerous or At Risk. These appliances must not be used and should be replaced as soon as is possible. If the gas engineer discovers an issue that they are unable to fix, they will terminate the appliance from the gas supply and write this on the certificate.
