Find the Right Boiler for Your Home
Choosing the right gas boiler depends on your home size and heating needs. For compact spaces like flats and small homes, a combi boiler (24–28 kW) is a compact, all-in-one unit that heats water directly from the mains, saving space and energy. Medium-sized homes with multiple bathrooms benefit most from system boilers (28–34 kW), which provide a reliable supply of hot water on demand with the help of a hot water cylinder. For larger properties or households with traditional radiator systems, heat-only (regular) boilers delivering 35 kW or more are ideal to meet higher heating demands.
If you’re uncertain which boiler suits your home best, our experts can guide you toward a model that balances comfort, performance, and efficiency.
Energy Efficiency and Cost Savings
Modern gas boilers are designed for efficiency, helping you reduce energy consumption and cut heating bills significantly. Upgrading from an old or inefficient boiler can save you hundreds of pounds annually, making it a smart investment for long-term comfort and savings. Gas boilers also heat water quickly and provide reliable warmth throughout the colder months, ensuring your home stays cosy year-round without sacrificing efficiency.

To ease upfront costs, we offer flexible finance plans with £0 deposit, allowing you to spread payments over time while enjoying the benefits of a new boiler immediately.
