Prices for gas boilers

Gas boilers are by far the most popular type in the UK, so there are a number of different models and makes to choose from. The final cost of your new gas boiler will ultimately depend on the type of unit you choose and the quality of your chosen brand. We spoke to a number of different providers and manufacturers to find out just how much a conventional, condensing gas system boiler would be, and they provided us with the following figures (which don’t include installation costs):

• British Gas –  £1,500 to £3,800 (the higher end prices include boiler, new radiators, expert thermostatic controls and a preliminary check for easy installation)
• Npower –  £800 to  £2,000 (although in an effort to match the government benefit schemes available to those on income support, npower are currently offering boiler deals for as little as £200 to £400)
• Baxi –  £600 to £1,000 for boilers with a 24 to 30 kilowatt (kW) Heat Output Rating
• Vaillant –  £750 to £1,400 (including eco-friendly options, and with a Heat Output Rating of 24 to 36 kW)
• Worcester Bosch –  £800 to £1,700 (with a 28 to 44 kW Heat Output Rating)

There are a huge number of different gas suppliers and other boiler manufacturers you can get in contact with to find out just how much a new gas boiler will cost. When you collect quotes, don’t forget to find out exactly what is included in your final contract, for instance check whether the price includes a warranty and annual service checks. Whatever you choose, don’t be tempted to purchase a second-hand or knock-off model; the low price might seem appealing, but you’re likely to end up with an inefficient boiler.
