Evaluate Combi Boiler Prices

What Is the Price of a Combi Boiler?

With a combi boiler, you can save a lot of money in terms of cutting down the costs of hot water. It has some great benefits since it comes without the water tank, which makes it very compact and easy to install.

Combi boiler prices in the UK depend on the size and output of the boiler and the fuel it burns. Generally, the type and size of the combi boiler should be in accordance with the size of your home. For example, a small combi boiler would be suitable for a household with 1 bathroom and up to 3 bedrooms, costing approximately £700. The following table can give you an overview of boiler prices according to house size:

Overview of Combi Boiler Prices
House Size No. of Bedrooms No. of Bathrooms No. of Radiators Power Output Price Range
Small House 1-2 1 10 24-27kW £599 - £1,499
Medium House 3-4 1-2 15 28-35kW £699 - £2,199
Large House 4+ 2+ 20 36-42kW £799 - £1,999

It can be challenging to figure exact combi boiler prices, since the available boilers vary a great deal in their price and functions.

It makes sense that a super cheap new combi boiler costing around £300 – £500 will not be as reliable as £700+ boilers that come with a warranty. The fact that you would need some extra parts with cheap boilers can become a real problem since these parts can be hard to find and are mostly expensive.

In the case of having one or two bathrooms and up to 5 bedrooms, medium-sized combi boiler would be relevant, costing around £1,000. For three or more bathrooms and more than 5 bedrooms, a large, often commercial-strength combi boiler would be a suitable choice, with an estimated price of £1,500.

We provide you with a free of charge and no-obligation service that allows you to request boiler quotes and compare different systems so that you can find the best combi boiler deals most suitable for you. Just fill in the form on the right to request offers by trusted suppliers in the UK.
