Boiler Servicing Checklist

Annual boiler servicing is a crucial part of boiler and heating system maintenance to ensure it is operating safely and efficiently.

Additionally it is a condition of the boiler warranty, so you’ll need to ensure your boiler is serviced every year to ensure that warranty is valid.

Service work should be conducted by a Gas Safe registered engineer. This means that they’re competent to perform the work on your appliance. You should check them out on the Gas Safe register web-site.

The subsequent checks should be made during a service:

Step 1 – Safeguarding your home
Your heating engineer will use protective sheets and show covers to protect your home throughout the service.

Step 2 – Visual check
The annual service will then be started with a visual check to be certain that the boiler, relevant pipework and flue are installed and placed properly, both internally and externally. The general operation of the boiler is then observed and a check for suitable ventilation is also carried out if required.

Step 3 – Checking it’s working safely
The engineer will remove the boiler casing to take a look at its parts. They will check the boiler is working properly and efficiently. A good service will include checking:

# Correct gas pressure and flow
# Flue and combustion. A flue gas analyser (where suitable) can be used to ensure that the boiler is using the ideal mixture of gas and air.
# Electrical contacts are clean and in great condition
# Fans along with other key components operate correctly
# Seals are intact
# Electrodes are in a good condition
# Safety devices are tested
# Condensate trap and pipe is not blocked
They’ll also clean inside the boiler where necessary and inspect the water and gas pipework to ensure things are all functioning effectively.

Step 4 – Safety checks
The engineer will complete a number of safety checks in accordance with gas regulation (GSIUR 1998) to give you further peace of mind.
