A combi (combination) boiler provides both central heating and hot water from one compact unit. It heats water directly from the mains when you turn on a tap, so there’s no need for a separate hot water cylinder or cold water storage tank.
Heats water directly from the mains – Hot water is delivered on demand, so you don’t have to wait for a tank to refill or reheat.
No hot water cylinder required – Frees up cupboard or loft space, making it ideal for homes where space is limited.
Compact and space-saving – Most combi boilers fit neatly into a kitchen cupboard.
Energy efficient – Because water is heated only when needed, combi boilers can help reduce energy waste and lower bills.
Ideal for small to medium homes – Best suited to properties with 1–2 bathrooms and good mains water pressure.
Combi boilers are one of the most popular choices in UK homes due to their efficiency, convenience and space-saving design.
-
Yes – in most cases you can replace a conventional (regular) or system boiler with a combi boiler. This is known as a boiler conversion.
The installer will remove the hot water cylinder and, if applicable, the cold water tank, then reconfigure the pipework so the combi heats water directly from the mains.
This will typically free up valuable space in your airing cupboard and loft.
-
Yes – your installer will remove the old boiler and safely dispose of it. The whole process is managed for you, start to finish.
-

Small property – £1,600–£2,200
3-bed semi – £2,200–£3,000

The exact cost depends on output size (kW), brand, and pipework changes.
-
It depends – if you’re switching boiler type or moving its location, you may need new pipework. Your installer will assess everything upfront and give you a clear quote.
-
