Common faults and breakdowns
Boiler suddenly stops or will not fire
No ignition, unexpected shutdowns or burner faults that leave the property without heat — including overnight failures in cold weather.

No heating or hot water
Sudden or partial loss of heating and domestic hot water linked to the oil boiler, pumps or associated controls.

Fuel delivery problems, nozzle and hose issues, electrode faults and related burner components that stop the boiler firing reliably.

FAQs
Frequently asked questions
Do you offer 24-hour emergency oil boiler repairs?
Yes — evenings, overnight, weekends and bank holidays are covered for oil boiler breakdowns, subject to engineer availability and location. Details are on our 24/7 emergency oil boiler repairs page.
Can you attend an oil boiler breakdown on the same day?
Urgent daytime breakdowns are prioritised where diary capacity allows. We do not guarantee fixed response times — call with your postcode and symptoms so we can advise on the soonest practical attendance.
Why does my oil boiler keep locking out?
Repeated lockouts can be caused by ignition faults, fuel supply problems, burner components or combustion issues. Professional diagnosis is needed to identify the underlying cause — avoid repeated resets without investigation.
What should I check before calling?
Confirm there is oil in the tank, check any isolation valves are open, and note whether the boiler shows a lockout or fault light. Do not repeatedly reset a boiler that keeps failing. If you smell oil strongly, ventilate, avoid ignition sources and seek help promptly.
Can you repair all oil boiler brands?
We work on a wide range of domestic oil boilers commonly found across Berkshire and Hampshire. Share your make and model when you enquire and we will confirm suitability.
Is it worth repairing an old oil boiler?
It depends on age, parts availability, repair cost and overall condition. We give straightforward advice so you can decide between repair and replacement.
