Professional Gas Boiler Service
Regular maintenance by Gas Safe engineers ensures safe, efficient operation and extends boiler lifespan.
When Does Your Gas Boiler Need Servicing?
Your gas boiler needs servicing annually, regardless of apparent issues, to maintain safety and efficiency. Signs that indicate your boiler specifically needs immediate attention include unusual noises (banging, whistling, or gurgling), yellow flames instead of blue, frequent pressure drops, water leaks, or higher-than-normal energy bills. If your boiler is over 10 years old or showing these symptoms, contact a Gas Safe registered engineer immediately.
Important Safety Note: Annual gas boiler servicing is not just recommended but essential for safety. Carbon monoxide leaks from poorly maintained boilers can be fatal and often present no warning signs.
5 Visual Warning Signs Your Boiler Needs Maintenance
Yellow Flames
Healthy gas boiler flames should be blue. Yellow or orange flames indicate incomplete combustion, which can produce carbon monoxide. This requires immediate attention from a Gas Safe engineer.
Danger Level: High - Call a Gas Safe engineer immediately
Unusual Noises
Banging, whistling, gurgling or humming sounds from your boiler indicate potential issues like air in the system, pump failure, or limescale build-up. These sounds usually worsen without maintenance.
Danger Level: Medium - Schedule service within 1-2 weeks
Dropping Pressure
If you need to frequently repressurise your boiler, there may be a leak in your system. The pressure gauge should typically read between 1-2 bar. Consistently low pressure needs professional inspection.
Danger Level: Medium - Schedule service within 2-3 weeks
Water Leaks
Water pooling around your boiler indicates a leak, potentially from a damaged internal component, loose connection, or corroded pipe. Even small leaks can cause significant damage and should be addressed promptly.
Danger Level: Medium to High - Schedule urgent service
Higher Energy Bills
A sudden increase in energy consumption despite similar usage patterns often indicates declining boiler efficiency. Annual servicing can improve efficiency by up to 15%, significantly reducing your bills.
Danger Level: Low - Schedule regular service
Remember:
Even without visible warning signs, your gas boiler should be serviced annually by a Gas Safe registered engineer. This ensures safety, maintains efficiency, and extends your boiler's lifespan. Many manufacturers require annual servicing to maintain warranty coverage.

Common Boiler Issues in Exeter Properties
Through our extensive experience servicing gas boilers in the Exeter area, we've identified several issues that are particularly common in local properties:
- Hard Water Scaling - Exeter's water supply has moderate to high calcium levels, causing limescale buildup in heat exchangers, particularly in older properties in St Thomas and Heavitree.
- Pressure Fluctuations - Properties in hillside areas like Pennsylvania and parts of St Leonard's often experience boiler pressure issues due to the varying elevations.
- Cold Weather Performance - During Devon's cold snaps, particularly in exposed areas like Exwick and rural properties outside the city center, frozen condensate pipes become a common issue.
- Older System Compatibility - Period properties in central Exeter and Topsham often have heating systems that require specialized maintenance to work efficiently with modern boilers.
Our local engineers are familiar with these regional challenges and come prepared with the solutions specific to Exeter homes and businesses.
What Our Exeter Customers Say
Sarah Thompson
