A heat only to combi conversion involves replacing your existing heat only (or regular) boiler and hot water cylinder with a combi boiler, which provides both heating and hot water directly from the boiler itself

Combi boilers deliver hot water on demand directly from the mains, removing the need for a hot water cylinder or cold water storage tank. This can save significant space in your property. They are also typically more energy efficient, potentially reducing your energy bills

The cost of converting from a heat only boiler to a combi boiler can vary depending on the complexity of the job and the model of the new boiler. On average, it can cost between £2,500 – £4,500

The hot water cylinder is typically removed during a heat only to combi conversion, freeing up space in your home

Like all boilers, combi boilers should be serviced annually to ensure they are working efficiently and safely. Regular maintenance can also help prolong the life of your boiler

With proper maintenance, a combi boiler can last up to 15 years or more
