Common boiler issues we can resolve
No Heating or Hot Water
Often caused by thermostat issues, low water pressure, or broken motorized valves.
Low Boiler Pressure
Can be due to leaks, recently bled radiators, or faulty pressure relief valves.
Leaking Boiler
Water leaks can stem from corroded pipes, pump seals, or faulty pressure valves.
Kettling (Boiler Making Loud Noises)
Caused by limescale buildup on the heat exchanger, leading to overheating and banging noises.
Pilot Light Goes Out
Often due to a broken thermocouple, a faulty gas valve, or air in the gas line.
Frozen Condensate Pipe
In cold weather, the condensate pipe can freeze, causing the boiler to shut down.
Radiators Not Heating Up Properly
May be caused by trapped air (needs bleeding), sludge buildup, or faulty thermostatic radiator valves.
Boiler Keeps Switching Off

Boiler Installation & Repair FAQs
What are the most common boiler problems?
Common boiler faults include low pressure, no heating or hot water, kettling noises, thermostat issues, frozen condensate pipes, leaking boilers, and faulty pilot lights. Our experienced Gas Safe engineers diagnose and fix these issues quickly and safely.
Should I repair or replace my boiler?
If your boiler is over 10–15 years old, frequently breaking down, or no longer energy-efficient, a new boiler installation may save you money long-term. We offer honest advice and can provide free quotes on boiler replacements with no pressure.

A standard combi boiler swap typically takes 1–2 days. More complex installations, such as system upgrades or relocating the boiler, may take longer. We’ll provide a clear timeframe before work begins.

Absolutely. All boiler repairs and installations come with a 6-month workmanship guarantee, plus full manufacturer warranties on parts and new boilers.
