What is the cost of a new boiler?

Is this something that you have asked or considered lately, especially given the escalating costs of energy bills? 

The cost of a new boiler installation is dependant on a variety of factors like but not limited too:

  • What type of boiler you are considering? Make & Model.
  • The type of boiler you would like to consider, from a combi to system boiler.
  • Are you not happy with the location of your boiler and would like to move it?
  • How big is your current property?
  • Are there future renovations that you are considering and will the boiler that you select accommodate these changes?
  • Are technical changes required to ensure that you are compliant with gas safety regulations and requirements? As an example, you may have to move the location of the flue.
  • Other extras like smart heating control or device

Notably, a straight-forward swap with your existing combi boiler tends to be the most popular choice and also the least expensive.

So how much does a new boiler typically cost?

Perhaps you are interested to know what a stand-alone boiler is going to cost you? A new combi boiler or system boiler typically costs between £600 to £900 pounds for an inexpensive model, where you can expect to pay between £900 to £1200 for a mid-range model and a top of the range model can set you back between £1000 to £2000 depending on the size of the model selected.

Your regular or heat-only boiler can cost anywhere between £500 to £2000, however, this again depends on the size and quality of the model selected.

What are the top factors that can affect the cost of a new boiler replacement:

  • Fact#1 – How much does the new A-rated boiler actually cost?
  • Fact#2 – Who is going to install the new boiler, are they gas safe registered and what do they or the company charge in labour for an installation?
  • Fact#3 – Do you need to install a new flue, in particular, a vertical flue and how much would that cost?
  • Fact#4 – Do you need a plume kit? Where perhaps your boiler’s flue is to close to a window, door or the neighbour. Note it is also a requirement by law to comply with the Gas Safety regulations and standards.
  • Fact#5 – Do your main gas pipes require an upgrade? Older central heating systems typically had piping with a width of 15mm, however with the new gas regulations a 22mm width is required.
  • Fact#6 – Yes? You want to relocate the boiler. Does not fit your finishings in your newly renovated kitchen, however, the costs incurred amount to labour costs, changes in pipework, fixtures and fittings. 
  • Fact#7 – Do you need a shiny new smart heating controller that can be accessed via your smart device on an internet line? 
  • Fact#8 – A longer warranty? Is that a cost that you want to incur?
  • Fact#9 – Do you want to ensure that your boiler is free from dirt and metal pieces that could cause damage to your boiler or worse still boiler leaks. You may then have to consider having magnetic filters installed. In most cases this may be a requirement from the manufacture should you take out an extended warranty.
  • Fact#10 – Do you need a chemical flush, which clears your central heating system, ensuring that sludge does not stop the hot water from flowing around. Much like a clogged artery.
  • Fact#11 – Do you need new radiators? What do they typically cost? If you have an old heating system, then it is normal for the radiators to experience wear and tear making them less efficient and increasing your energy bills.
