Gas Boiler Servicing
Why Bother Servicing Your Gas Boiler? In a nutshell, because it’s cost-effective to do so. You only have to think about the possibility of your boiler developing a problem and that problem remaining undetected until it escalates into something major.
And ‘major’ often involves a costly repair. But that’s the best case scenario. What if it can’t be repaired and you need to replace that boiler altogether? A regular service can get you ahead of those potential issues so that they’re identified and resolved before they get worse. But that’s not all a service can do. By maintaining your boiler on a regular basis, your boiler engineer will make sure that its working to its optimum so that your system remains efficient and your bills substantially curtailed. A service can also spot carbon monoxide leaks and ensure that your warranty remains valid.
It’s a no brainer really. The only question remaining is who is going to provide that service? That’s where come in at Assured Heating.

Combi Boiler Servicing FAQs
Q: How often should I have my combi boiler serviced?
A: It is generally recommended that your combi boiler is serviced once a year. Regular servicing helps keep the system running efficiently, identifies potential issues early, and supports safe operation.
Q: Why is annual boiler servicing important?
A: Annual servicing helps improve efficiency, reduce the risk of unexpected breakdowns, extend the lifespan of your boiler, and ensure components are operating correctly.
Q: What happens during a combi boiler service?
A: A typical combi boiler service includes inspecting key components, checking gas pressure, testing safety controls, examining the flue, cleaning parts where necessary, and ensuring the boiler is operating correctly and safely.
Q: How long does a combi boiler service take?
A: A standard combi boiler service usually takes between 30–60 minutes, depending on the boiler model and whether any issues are discovered.
Q: Can servicing help lower energy bills?
A: A well-maintained boiler can operate more efficiently than one that has not been serviced regularly. Improved efficiency may help reduce energy consumption and heating costs.
Q: Will servicing help prevent boiler breakdowns?
A: While servicing cannot guarantee that a boiler will never develop faults, it can identify worn components and potential problems before they become major issues.
Q: Does a new combi boiler still need servicing?
A: Yes. Even newly installed boilers should be serviced annually. Regular maintenance helps maintain performance and is often required to keep manufacturer warranties valid.
Q: Can I service my own combi boiler?
A: Boiler servicing should be carried out by a qualified engineer with the appropriate gas safety qualifications. Internal gas components should not be dismantled or repaired without the proper training.
Q: What are the signs that my combi boiler may need attention before its next service?
A: Signs can include unusual noises, reduced heating performance, low boiler pressure, leaks, inconsistent hot water, radiators not heating correctly, or fault codes appearing on the display.
Q: What happens if I skip annual boiler servicing?
A: Missing regular servicing can increase the risk of reduced efficiency, unexpected repairs, component wear, and may affect manufacturer warranty conditions.
Q: Can a boiler service detect carbon monoxide risks?
A: During a service, safety checks are carried out to identify potential issues that could affect safe operation, including checks relating to combustion and ventilation.
Q: Is boiler servicing different from boiler repairs?
A: Yes. Servicing is preventative maintenance carried out regularly to keep the boiler operating efficiently. Repairs are carried out when a fault or breakdown occurs.
Q: Do landlords need annual boiler servicing?
A: Landlords have legal responsibilities regarding gas safety checks and maintaining gas appliances in rental properties.
Q: Should I service my boiler during summer?
A: Many homeowners choose to arrange servicing during warmer months, as heating demand is lower and appointments can sometimes be more flexible.
