Boiler Cost Guide

Installing a new boiler will keep your home warm; energy efficient and can help reduce your fuel bills too. Find out how much a new boiler will cost you with our handy guide.

Boilers vary in cost depending on their type and make, as well as what fuel they burn. Generally you’ll need to choose between a gas, electric or oil fired model; you’ll also need to choose whether to install a combi or system boiler:

A system boiler – the traditional option, system boilers have a tank which is normally located in the loft to store hot water in. It’s a good idea to choose a system boiler if you have a large household, more than one bathroom or extensive hot water needs in general.

A combination boiler (combi-boiler) – a combi boiler is the most popular choice these days and is perfect for smaller homes with less extensive hot water needs as it heats water on demand. Combi boilers are also small and compact, which means they don’t require much space.

How Much Does a New Boiler Cost?

  • The Energy Saving Trust (EST) says that the average cost of a new gas combi boiler is around £2,300 including VAT and professional installation
  • You may be able to pick up a cheaper combi boiler if you buy a second hand or reconditioned model. For example, an ex-showroom combi boiler may cost around £450 to £750 (not including installation costs)

Boiler Installation Cost

You’ll need to factor in the cost of having your new boiler installed by a qualified boiler engineer – this is essential to ensure that your boiler is safe and runs efficiently. That means hiring a Gas Safe registered engineer if you have a gas boiler, a qualified electrician for electric boilers, an OFTEC engineer for oil-fired heating or a HETAS registered professional for solid-fuel burning boilers. According to Which?:

  • The average cost of boiler replacement (replacing one boiler with a new one) is £600
  • The cost of new boiler installation (installing a boiler in a new location) is between £1,500 and £1,800

Boiler Running Costs

It’s worth considering how much your boiler will cost to run once you’ve installed it. This will obviously vary depending on how much heating and hot water you use as well as how well-insulated your home is, but Which? says that on average:

  • Gas boilers cost around £720 per year to run
  • Electric boilers cost around £1,600 per year to run
  • Oil-fired boilers cost around £1,100 a year to run

How Much Does a Boiler Service Cost?

In order to ensure your boiler continues to run safely and efficiently, you should make sure you get yours serviced at least once a year, or more if the manufacturer recommends.

  • According to the EST, a boiler service check costs between £50 and £75

Depending on the results of your service, you may need to pay boiler repair costs.

Boiler Grants

You may be eligible for a free or subsidised boiler, especially if you’re over 60 or on benefits, through one of the following schemes:

  • Scottish Boiler Scrappage Scheme – eligible Scottish candidates will get £400 off the cost of a new boiler under this scheme
