Boiler problems always seem to show up at the worst possible moment, and although some issues need a professional straight away, others are easier to understand and sometimes quick to resolve.
Low Boiler Pressure
Low pressure is one of the most common boiler issues – you’ll usually notice it on the pressure gauge. This can happen because of a small leak or after bleeding radiators, and repressurising the boiler using the filling loop often solves the problem, but if pressure keeps dropping, it’s best to get it checked.
No Heat or Hot Water
If your boiler isn’t producing heat or hot water, the issue could be a faulty thermostat, a timer setting, or low pressure. Check your controls first to make sure everything is set correctly; if the boiler still doesn’t respond, professional help is usually needed.
Strange Noises
Banging, whistling, or gurgling sounds often point to trapped air, limescale buildup, or pressure issues. Bleeding radiators can sometimes help, but persistent noises shouldn’t be ignored, and they usually mean internal problems that need attention.
Radiators Heating Unevenly
Cold spots on radiators usually mean sludge has built up inside the system – power flushing or system cleaning can restore proper heat flow.

Final Thoughts
Some boiler problems have simple explanations, but boilers are complex systems, and if issues keep returning or you’re unsure what’s causing them, it’s always safer to call a qualified engineer.
