Why Gas Boiler Repairs in London Are So Important

Common Gas Boiler Problems
Professional engineers regularly deal with a wide range of boiler faults. Some of the most common gas boiler issues in London include:

2. Low Boiler Pressure
Often due to water leaks or bleeding radiators. Low pressure reduces heating efficiency and can shut down the boiler entirely.
3. Strange Noises
Banging, gurgling, or whistling sounds (also known as kettling) usually indicate limescale buildup or trapped air.
4. Boiler Leaks
Leaks may come from internal components such as pressure valves or pumps and should be repaired immediately to prevent further damage.
5. Pilot Light Keeps Going Out
This may be caused by a faulty thermocouple, gas supply issue, or debris buildup.
