Boiler installers with expert knowledge

An old, inefficient boiler could be costing you an extra £210 on your heating bills – every year. As experienced boiler installers we also know that ageing boilers are likely to be less reliable, with unexpected failures and breakdowns disrupting home and work life, leaving you with emergency repair and replacement costs.

Heating accounts for around 60% of your household energy bills1, so a boiler replacement could really help bring down costs. Your home will be warmer, cosier and more comfortable too.

We’re leading boiler installers and heating experts for homes throughout Berkshire, Surrey, Hampshire and Oxfordshire. Every boiler replacement or installation is carried out by experienced, fully qualified GasSafe and OFTEC registered engineers, and all come with guarantees of workmanship and a boiler warranty.
