Experiencing costly heating bills? It’s estimated that an average boiler can be as low as 60% efficient, which means only 60 pence of every pound spent on heating is being put to good use.

Mostly all new boilers are condensed, which results in a large improvement in efficiency by using waste heat in flue gases to pre-heat cold water entering the boiler. Our team of engineers are fully qualified and able to fit any kind of boiler. For more information, visit our boiler installation page to read more.
