Baxi Boilers: Prices, Models, & Reviews (2025)

Baxi has a wide range of boilers of numerous types. The Baxi 600 and 800 lines are available as combi, system, and conventional boilers. While most of their boilers are gas-powered (with LPG compatibility), Baxi also offers electric models under the Heatrae Sadia brand.

The 400, 600, and 800 models are LPG compatible with a kit, while Duo-tec Compact, Megaflo system, and Platinum Compact don’t require a kit for LPG compatibility.

While any Baxi model may not be the most efficient boiler, it can still compete with the best. They provide a wide variety of combi boilers, which can provide adequate savings for small to medium-sized homes.

So, how much is a baxi boiler going to cost? Baxi boiler prices range from £650 to £3,000, including gas and electric boilers of all types. Baxi combi boiler prices in the UK start at the lowest range, with models like the 400 Combi 2.1 as low as £650. System and conventional boilers are more expensive, starting at £900.

Baxi combi boiler prices range from £650 to £1,600. Higher output versions tend to be more expensive, but even cheap Baxi boilers, like the 400 Combi, can be a good addition to a smaller home (2 bedrooms, for example).

Baxi system boilers range from £900 - £1,300, being most suitable for medium to large homes.

Baxi conventional boilers can be between £900 and £1,800, being suitable for small to large homes. Although these boilers can be a good fit for small homes, combi and system boilers can be easier to install, and most smaller homes do not have a loft space.

Baxi boiler installation cost can vary based on the type of boiler and the one you’re replacing it with. A like-for-like boiler change is far less expensive, while swapping a conventional boiler for a combi will require removal of parts and reattachment. Similarly, putting in a system boiler or a conventional boiler will also require adding additional parts.

Baxi also provides 2 electric boilers: Amptec Electric and Electromax Electric boilers. Both these boilers are sold under the Heatrae Sadia name, which is part of the Baxi brand. Baxi’s electric boilers cost between £850 and £3,000.
