Helpful Boiler & Heating Information
What should I do if my boiler stops working?
If your boiler stops working, check the basics first: power, pressure and thermostat settings. If the issue continues, it is best to contact a qualified heating engineer.
How often should a boiler be serviced?
Most boilers should be serviced once a year to help keep them safe, efficient and working properly.
Common signs your heating system needs attention
Cold radiators, unusual noises, pressure drops, or slow heating can all be signs that your system needs inspection or repair.
Boiler repair or boiler replacement?
Some boiler faults can be repaired, but older or unreliable boilers may be better replaced. A proper inspection can help you decide the best option.
What is an unvented hot water cylinder?
An unvented cylinder stores hot water under mains pressure. These systems should only be checked and repaired by someone with the right experience and competence.
How to prepare before an engineer’s visit
Before your appointment, make sure the boiler or heating system is accessible and note down any fault codes, noises or problems you have noticed.
