Frequently Asked Questions
Why has my boiler stopped working?
There are many causes such as low pressure, ignition faults, sensor failures, frozen pipes, blocked heat exchangers or faulty pumps. We diagnose the exact fault on arrival and give clear options before any work is carried out.
How quickly can you attend a boiler breakdown?
We offer fast local response with same-day callouts where possible. In winter we prioritise homes with no heating or hot water.
Do you offer emergency same-day boiler repairs?
Yes — if your boiler has no heat, no hot water, or a serious leak, we prioritise same-day emergency callouts wherever possible.
How much does a boiler repair cost?
Repair costs vary depending on the fault and any parts required. We always provide clear, upfront pricing before carrying out any repairs, with no hidden fees.
Do you repair all boiler makes and models?
Yes. We repair all major brands including Worcester, Vaillant, Ideal, Baxi, Glow-worm, Viessmann, and more. Older boilers and discontinued models can often be repaired too.
What happens if my boiler can’t be repaired?
If a repair isn’t safe or cost-effective, we’ll advise honestly. We can quote for replacement options, explain the pros and cons, and help you make the best decision for your home.
Is it better to repair or replace my boiler?
Repairing is usually best for younger boilers with isolated faults. If your boiler is 10–15+ years old, repeatedly breaking down, or parts are unavailable, replacement may be more cost-effective long term.
Frequently Asked Questions
Do you repair boilers with no heating or hot water?
Yes. This is one of the most common faults. It can be caused by diverter valves, sensors, pumps, or ignition issues — we diagnose and repair the problem quickly.
My boiler keeps losing pressure — can you repair it?
Absolutely. Pressure loss is normally caused by leaks, expansion vessel issues, PRV faults, or internal component failures. We locate the cause and fix it properly.
Do you repair leaking boilers or pipework?
Yes — we repair internal leaks, external leaks, faulty seals, condensate leaks, PRV discharge, and radiator/pipework leaks linked to boiler faults.
Can you fix noisy boilers (banging, whistling, kettling)?
Yes. Noisy boilers usually indicate scale buildup, air in the system, pump issues, or failing components. We diagnose the cause and resolve the noise safely.
Do you repair ignition, flame failure, or lockout faults?
Yes — ignition issues are common. We repair electrode faults, PCB problems, blocked flues, gas supply issues, and sensor faults that cause repeated lockouts.
Do you repair broken thermostats, timers, or smart controls?
Yes. We repair or replace faulty thermostats, programmers, and smart systems including Hive, Nest, and Tado.
Do you repair older boilers and back boilers?
Yes, where parts are still available and the repair is safe. If the unit is obsolete or unsafe to repair, we’ll provide honest advice on your best options.
