Boiler Types & Prices
Combi Boilers
The most popular choice across the UK, combi boilers provide both heating and hot water from a single compact unit—ideal for homes with limited space and no hot water cylinder.
System Boilers
Perfect for homes with higher hot water demand. System boilers store hot water in a separate cylinder, making them great for properties with multiple bathrooms.
Standard (Conventional) Boilers
Also known as regular or heat-only boilers, these systems use both a hot water cylinder and a cold water tank—suited for older homes with traditional heating systems.
Heat Pumps
An energy-efficient alternative to gas boilers, heat pumps extract heat from the air or ground and typically run at around 300% efficiency—cutting both emissions and energy costs. COMING SOON
