Boiler Repair services in Abergavenny

Boiler repair starts with a diagnostic call-out: the engineer reads any error/fault codes, inspects the pressure gauge, checks the pump, diverter valve, PCB, expansion vessel and gas supply, then quotes for the parts required.

Any work on a gas appliance must be carried out by a Gas Safe registered engineer — it is a legal requirement in the UK. Ask to see the engineer's Gas Safe ID card; the licence number can be verified on the public register.

Repair vs replace: as a rule of thumb, if your boiler is 12+ years old, a major component failure (heat exchanger, PCB) often means replacement is more economic. For boilers under 8 years, repair almost always wins. The Boiler Upgrade Scheme offers £7,500 towards air source heat pumps if you are considering switching.
