Poorly-maintained boilers don't just cost more to run, producing less heat for the gas consumed, they can also kill by giving off poisonous carbon monoxide fumes.
If you are a landlord, it is a criminal offence not to have your boiler serviced annually and certified by a CORGI registered installer like David Payne. And in your own home, it's your own and your family's life at risk. So don't delay: get your boiler serviced by a Corgi-registered gas installer - and who better than David Payne, your local home heating expert?
