Common Boiler Problems We Help With
No hot water
Hot water faults can be caused by diverter valves, sensors, pressure problems, controls or other components.
Pressure loss
Repeated pressure loss may be caused by leaks, expansion vessel issues, pressure relief valve problems or system faults.
Error codes
Modern boilers display fault codes that help point towards ignition, fan, sensor, pump, pressure or combustion issues.
Boiler leaks
A leaking boiler should be checked promptly to prevent water damage and possible safety concerns.
Boiler keeps locking out
Repeated lockouts need proper diagnosis rather than repeatedly resetting the boiler.
How Common Boiler Faults Are Diagnosed
No heating, no hot water, pressure loss, leaks and lockouts can have several possible causes. A diverter valve, pump, sensor, expansion vessel, pressure relief valve, ignition fault or controls issue may be involved, so proper boiler repair diagnosis matters more than guesswork.
What To Check Before Calling
A few safe checks can make the first conversation more useful. Do not remove the boiler casing or try to work inside the appliance.
- Check the thermostat settings
- Check the boiler pressure if the display is visible
- Check the power supply and any obvious switched spur
- Check whether heating, hot water or both are affected
- Note any error code shown on the boiler
- Do not remove the boiler casing
- If you smell gas, call 0800 111 999 immediately
Repair or Replace?
Some boiler faults are straightforward to repair. Others become harder to justify when the appliance is older, parts are expensive or several faults are appearing close together. We will explain what has been found, likely repair costs and whether a new boiler should be considered instead.
Boiler Brands Repaired
We work with many common domestic boilers including Worcester Bosch, Vaillant, Baxi and Ideal. Brand, model and fault code details are useful when you enquire because they help narrow down likely causes.
Clear Diagnosis Before Repair Work
We aim to explain what has been found, what the repair options are and whether the boiler is worth repairing. If replacement is more sensible than ongoing repair costs, we will explain that clearly without pressure.

Questions Customers Ask
Can you repair my boiler the same day?
Same-day help may be available depending on workload, parts and the type of fault. Some issues can be diagnosed quickly, while others need parts or further investigation. If you can provide the boiler make, model and error code, it helps set realistic expectations before the visit.
What should I do if my boiler loses pressure?
Top it up only if you know how to do so safely and the manufacturer instructions are clear. If pressure keeps dropping, repeated topping up is not a fix. It may point to a leak, expansion vessel issue, pressure relief valve fault or another heating system problem that needs proper diagnosis.
Should I repair or replace my boiler?
That depends on the boiler age, parts cost, reliability and whether more faults are likely. A newer boiler with a clear single fault may be worth repairing, while an older boiler with repeated breakdowns can become poor value. We will explain the options before you commit to repair work.
Do you repair all boiler brands?
We work with many common domestic boiler brands including Worcester Bosch, Vaillant, Baxi and Ideal. The exact repair route depends on the model, fault code, appliance condition and parts availability. Brand and model details are useful when you first get in touch.
What if I smell gas?
Call the National Gas Emergency Service immediately on 0800 111 999. Do not use electrical switches, smoke, or try to investigate the appliance yourself. Gas emergencies need to be handled through the emergency service first.
