Combi (combination) boilers are the most popular and cost-effective choice for many homes. They provide heating and hot water from one compact unit, heating water directly from the mains whenever a tap is turned on.

They’re ideal for properties with limited space, as they don’t require a hot water cylinder or rooftop tank. Combi boilers are also highly efficient because they only heat the water you use. Installations are typically quick—often completed within half a day.

Because they rely on mains pressure, you may notice reduced flow if multiple taps or showers are used at once. In homes with higher hot water demand, a system boiler may be a better fit. We offer combi boilers with up to 12 years manufacturer’s warranty.

System boilers store hot water in a cylinder but house most other components within the boiler itself. They’re perfect for homes with multiple bathrooms where hot water may be needed in several places at once.

With no loft tank required, they suit homes without usable roof space and are compatible with solar thermal systems for a more eco-friendly setup.
They do require room for a hot water cylinder, and because they store heated water, they’re slightly less efficient than combi.

We offer system boilers with up to 12 years manufacturer’s warranty.

Regular (traditional) boilers work with both a hot water cylinder and, in many cases, a cold-water tank in the loft. They’re ideal for older homes with existing vented heating systems, especially where the pipework or radiators may not handle the higher pressure of a modern combi or system boiler.

They can supply multiple taps or showers at once without a drop in pressure and may work well in areas with low mains pressure. Regular boilers also pair effectively with solar thermal systems.

However, they take up more space and store hot water, meaning you need to wait for it to reheat once the tank is emptied.
