Compare New Boiler Prices & Installation Costs

How much could it cost you to get a new boiler fitted in your home? Replacing your existing boiler is an expensive job, and you should always try and get as much information you can before deciding what boiler you should have fitted in your home.

Contacting a qualified engineer and getting a survey of your current boiler is always a good way to start, but sometimes you may want to do a bit of research yourself beforehand.

This is where we can help! We’ve done the research, so you don’t have to, compiling a list of boiler prices from all the major boiler brands to help you make an informed decision.

New boiler price range

Boilers vary in price massively, so it can be hard to understand why you would go for a more expensive boiler when there are budget options out there.

The price also varies depending on quite a few different factors, here are a few things that determine the overall cost of a new boiler:

The brand reputation for quality

kW output

Length of manufacturer warranty

Type of boiler (Combi, Heat-Only or System)

Type of fuel (Gas, Oil or Electric)

There are also several other factors that go into the pricing. In the range of boilers we have pulled together, prices start at £442 & go all the way to £3,426.56*.

New boiler brands

One of the main factors that affect price is the boiler brand. Some brands are considered premium such as Worcester Bosch & Vaillant due to their quality reputation and reliability which is endorsed by their awards. There are also budget brands out there such as Vokèra & Glow-Worm.

New boiler types & fuels price ranges

There are a variety of different boiler types and fuels to choose from when selecting a boiler. The boiler types on offer are Heat-Only (Regular), System and the most popular Combi boilers. As for the fuels available we have only gathered products for Gas & Oil as electric boilers and installers are few and far between.

New boiler installation prices

It’s difficult to give a concrete quote on how much it will cost to install a new boiler as it varies enormously dependant on your current situation. There are several different factors that go into determining the price of installation which includes:

• Having a like for like swap

• Additional parts may be required such as new gas pipes, condensate pipes, any extra tanks or any other building work

• If you are trying to keep the installation cheap you should keep the boiler in the same room, moving the boiler into another room will increase the cost.

• Some boiler brands are easier to install than others

• Where you live and the availability in your area.

If you provide your details then we will arrange for a leading boiler installer to provide you with a quote.

Saving & benefits of a new boiler

A new boiler replacement is likely to be expensive. You may take comfort in the fact that your new boiler could save you more money over the duration of its lifetime than it’s worth. New boilers are typically far more energy efficient than old ones amongst several other key benefits:

• Newer boilers tend to be quieter.

• You could reduce energy bills

• New boiler manufacturer warranty between 2 – 10 years.

• 90% of fuel is converted into heat on most modern condensing boilers.**

• A lot of new boilers come with better heating controls.
