Boiler Service
An annual inspection of a gas or oil boiler carried out by a Gas Safe (or OFTEC for oil) registered engineer to check that the appliance is operating safely and efficiently. A service typically includes checking for gas or flue leaks, cleaning internal components, testing safety devices, and adjusting settings. Many boiler warranties require annual servicing to remain valid; a service costs around £80–£120 and can identify faults before they cause a breakdown.
