Common faults
Boiler symptoms Nebula can investigate
Boiler faults can be caused by the appliance, controls, pressure, pipework or wider heating system. The first step is to explain what has changed.
No heating
Diagnosis for heating not coming on, radiators staying cold or controls not asking the boiler to fire.
No hot water
Help with hot water that is cold, intermittent or not behaving as expected.
Pressure and fault codes
Checks for boilers losing pressure, showing warning lights or displaying fault codes.
What to send
Useful information before a repair visit
Tell Claudia when the problem started, whether heating or hot water is affected, and whether anything has changed recently.
Do not attempt gas repairs yourself. If you smell gas, leave the property, avoid switches and call the National Gas Emergency Service on 0800 111 999.
- Photo of any fault code or warning light
- Current boiler pressure if visible
- Whether heating, hot water or both are affected
- Any noises, leaks or recent changes to controls

Absolutely brilliant service. My boiler had been throwing out two different errors multiple times a day. They came right out and gave it a thorough inspection and fixed the issue.
