Boiler services take 30-minutes to 1 hour for most gas boilers. Newer boilers can be serviced in just 30-minutes. Gas boilers take a little longer to service, around 1 hour to 2 hours. Servicing is well worth it in the long run as it helps boilers run smoothly and safely.

One common question homeowners have is whether horizontal and vertical radiators are checked during a boiler service. The answer is generally no. Only a comprehensive boiler service package might include an inspection of the radiators to ensure they are functioning optimally.

An annual service will start with a visual check to ensure that the boiler and associated pipework is installed and positioned correctly. Your engineer will then check that your boiler is operating correctly and identify any initial problems. Then they will remove the boiler casing to look at its components.
