An annual boiler service is an important part of boiler and heating system maintenance. It is also a condition of boiler warranties, so you will need to make sure your boiler is serviced annually to make sure warranty is valid. The heating engineer who carries out your annual service must be Gas Safe registered. You can check them out on the Gas Safe register website.
We were asked by a local householder to do his annual boiler service. We explained the process to him.
Step 1 – Visual check. The heating engineer will start the annual service with a visual check to make sure that the boiler and associated pipework is installed and positioned correctly. They will then check that your boiler is working correctly and identify any initial problems.
Step 2 – checking inside and cleaning. The engineer will remove the boiler casing to take a look its components. They will check the burner, main injector, condense drainage trap, seals and fans. They will clean inside the boiler and inspect the water and gas pipework to make sure everything is working correctly.
Step 3 – checking the flue and combustion. The engineer will check that the flue is safely fitted and not blocked. They will use a flue gas analyser to make sure the boiler is burning the right mixture of gas and air. This is to check that the boiler is operating efficiently and safely.
Step 4 – explaining what they have done. The engineer will tell you if the boiler does not meet any building and safety regulations. Make sure that they explain any repairs or maintenance work they need to do and that any parts used come from a reputable manufacturer, ideally from the boiler manufacturer.
Most boiler services should last around half an hour and you should receive a full service report. Only sign this report if you are happy with every element of the service your engineer has carried out.
Your engineer should fill in the service record which is part of the user guide and includes the Benchmark checklist. This document is needed if you ever need to make a claim during the length of your boiler warranty.
