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.

Whether it’s a combi boiler or a regular boiler, we only install the best A-rated new boilers from reputable manufacturers such as Worcester Bosch. Ask us about boiler replacement in areas surrounding Reading, Basingstoke, Bracknell, Guildford and Oxford.


We offer a range of efficient, high quality boilers: our expert, no-obligation survey can discover the best choice for your home and family needs. Replacing an older boiler with a new, high performing boiler can provide dependable home comforts such as a hot bath and a cosy living room, all while significantly reducing your heating bills.
