What happens during your annual boiler service?
Initial Inspection
During a boiler servicing, your appointed boiler engineer will thoroughly look at the overall condition of your boiler to assess its functionality. We will inspect the most important aspect of the boiler and its controls: safety. The controls regulate the flow of water and fuel so it’s vital they are working and are safe to use. We also check for leaks and obvious faults with the outside of your boiler.
Under the Hood
Once we’ve checked the outside of the boiler, we will pop off the outer casing and look through the internal components. We’ll carry out a gas pressure test to measure the pressure of your boiler and make sure it’s functioning at the right amount. Other tests we carry out include a flue test. This will check the CO and combustion ratio to ensure they are at a safe amount and not emitting an excess of carbon monoxide gas.
Clean Boiler
Lastly, we will clean any components of the boiler that need a tidy up and check for lime scale or debris. Once everything is in order, we will pop the outer case back on the boiler and give one last check. Before we leave, we will provide all relevant information about the boiler servicing that you can keep for your own records.

Frequently Asked Questions
How often should my boiler be serviced?
We recommend that you should get your boiler serviced annually to ensure it’s working properly. If your boiler is faulty it could result in your wasting a lot of money as it may start to leak carbon monoxide. As the poisonous gas is colourless and scentless, it can be difficult to tell if your appliances start to leak – therefore, it’s incredibly important to get a Gas Safe Registered engineer to check them.
What happens during the boiler service?
We will carry out a thorough check of your boiler to ensure it’s in working order. We’ll make sure that there’s no leaks or corrosion, inspections of main parts and carry out tests to check for unsafe fumes.
What is a Gas Safety check?
A gas safety check is a yearly inspection of all gas appliances in a home. If you use gas appliances – which most of us do – it’s a good idea to get them checked by a Gas Safe engineer (an engineer vetted by the Gas Safe Registry). After the check, you’ll receive a Gas Safe certificate that lasts for a year.
