A few sensible checks can help you work out what to do next.
Boiler help and simple first checks
These are simple first checks to help you decide what to do next, not a diagnosis. Never attempt gas work yourself, open the boiler casing, or remove any appliance covers.
Start with the signs you can see
Four checks for common boiler problems.
Safety first: never attempt gas work yourself. Do not open the boiler casing or remove appliance covers. For gas or boiler work, contact a suitably qualified, Gas Safe registered engineer.
