New Boiler Supply and Installation
Whether your current boiler has broken down beyond repair, been condemned, or is simply old and inefficient, our team handles everything from survey through to installation, testing, and aftercare. Every installation is carried out by Gas Safe registered engineers and backed by a fixed-price quote.
We supply and install three types of boiler, and will recommend the right one for your home during your free survey visit:
Combi boiler
Provides heating and hot water in one compact unit. No need for a separate tank or cylinder, making it a popular choice for smaller properties.
System boiler
Works alongside a hot water cylinder, making it well suited to homes with higher hot water demand.
Regular boiler
Also known as a conventional or heat-only boiler. Works with both a hot water cylinder and a cold water storage tank in the loft, and suits older properties with traditional heating systems.
Not sure which type is right for your home? We will advise you during your free survey visit.
Boiler brands we install
We only install boilers from manufacturers we trust. As accredited installers for Worcester Bosch, Vaillant, and Ideal, we have the training and expertise to install each brand to the standard the manufacturer requires, giving you the reassurance that your new boiler is in the right hands.
