What happens during a boiler service
- Visual inspection: We check the boiler casing, flue, pipework and ventilation for damage, corrosion or signs of leaks, and make sure the boiler is installed safely.
- Internal clean and checks: We open the boiler, clean the burner, heat exchanger and condensate trap, and check the seals, fan and electrodes for wear.
- Testing and paperwork: We analyse the flue gases, test the gas pressure and safety devices, fire the boiler up and give you a written record of the service.
Why an annual boiler service matters
A boiler that is serviced every year runs more efficiently and is much less likely to break down on the coldest night of the year. A gas boiler service also picks up early warning signs, such as a poor flame or worn seals, before they turn into costly faults. If you let a property, the law requires an annual gas safety check, and we can carry it out on the same visit. If your boiler is old or keeps letting you down, ask us about a new boiler installation.
