Boiler Breakdown Repair Company In Bristol
At MPW Group, we appreciate the need for a reliable boiler, especially during the colder seasons. A malfunctioning boiler can severely disrupt your daily lives and work and catch you off guard when without hot water and heat.
It is for this reason that we provide boiler repair services for both residential and commercial properties across Bristol and the surrounding area. Our highly skilled engineers are prepared to address any boiler-associated issue directly, restoring your boiler back to its original condition.


Common Boiler Faults That We Fix
- Low boiler pressure: This is one of the most common problems that is mostly a result of leaks, a broken pressure relief valve or air in the system. Low pressure can cause ineffective heating or worse a complete shutdown of the system.
- Thermostat complications: A malfunctioning thermostat that fails to respond or gives inaccurate temperature readings can disrupt the operation of the boiler. Damaged thermostats can be fixed or replaced within a short time and have the system back to its usual working conditions.
- No hot water: The reasons for the boiler pressure may also be the lack of hot water, the flame of the pilot, valves, and thermocouple etc. Our engineers offer services to fix the problem quickly and efficiently.
- Kettling: Found mostly in hard water areas, kettling is an occurrence associated with the build-up of limescale in the heat exchanger, causing banging or whistling sounds. Cold radiators may mean the system needs flushing to unclog any blockages that block proper circulation.
- Boiler switching off: The boiler persistently turning off may indicate that the pressure is low, the thermostat is faulty or the heat exchanger is blocked. These problems can be easily resolved by our engineers who are experienced in resolving such issues.
What are the Signs Your Boiler Needs to be Repaired?
- No heat or hot water: The lack of heating or hot water in your home can be caused by various issues, such as a faulty diaphragm or a malfunctioning valve. Our technicians will quickly identify the problem and get it resolved in no time.
- Unusual noises: Any banging, gurgling, or whistling noises from your boiler may be evidence of some kettling or even air being trapped. Most likely, these sounds are contributed to by limescale or other unwanted materials present inside the system and, should, therefore, be dealt with immediately.
- Boiler leaks: Water leaking from any point of your boiler is never a good indication. Leaks in this case could mean that the seal has failed or a component inside has gone bad and, if these leaks are not taken care of, could be the start of a more serious problem. If water is leaking from your boiler, you should contact an emergency plumber as soon as possible.
- Constantly turning off: With the boiler switched on, should the boiler go off intermittently, this failure may be caused by low pressure, overheating or a defective part – all of which should be solved as soon as possible to avoid other complications.
- Cold radiators: When your radiators are not getting hot, there could be a blockage of air or sludge that is preventing the flow of hot water. You may attempt to remedy the situation by bleeding the radiators which may offer a temporary solution but if the situation continues, chances are that a repair is going to be needed.

Boiler Repair FAQs
Regular boiler maintenance will minimise the chances of your boiler breaking down, and requiring expensive repairs.

Routine servicing helps maximise fuel efficiency, extend the lifespan of your boiler, and minimise the risk of unexpected breakdowns.
