New Boiler Costs 2022 – Average Boiler Costs UK

It’s time to replace your cranky old boiler – which option do you go for, and how much will you spend? Nobody seems to know the answer as there’s no definitive cost for a new boiler installation.

For many, the cost of a new boiler installation can be quite mysterious. Some boilers seem to be available at strangely low prices, while others have outrageously high price tags attached.

With so many options and so much misinformation, it’s easy to get confused when considering how much you can and should spend on a new boiler. Below is a brief look at what you need to know about new boiler costs in 2022.

What You Need to Know About Boiler Costs

The first myth that needs to be busted is that you must purchase your boiler from your gas or energy provider.

This myth is just that – it’s not true – it is only a myth. The next thing you need to know is that it’s all relative. This means that several factors determine the final cost of your boiler installation.

These factors include the following:

  • The cost of the boiler you would like to install. Some boilers are simply more expensive to install than others.
  • Whether you will install a regular, system, or combi boiler.
  • If the boiler will stay in the place of the existing boiler or be moved to a new position.
  • If there are any extras involved, such as filters and other smart control.

With all this said, it’s interesting to note that most British households opt for a pretty basic combi swap, and this happens to be the cheapest option too.

Factors That Influence The Cost Of A New Boiler

Several factors will determine the overall cost of your new boiler installation – see them below:

The Cost Of Standalone Boilers In The UK

A brand new boiler will set you back anything between £600 – £2,500. Budget combi boilers come in at around £600 to £900, with mid-range models sporting a price tag of £900 to £1,200 and premium models costing a whopping £1,000 – £2,000.

System boiler prices are similar, with entry-level units costing £600 to £900, mid-range costing £900 – £1,300, and then premium units coming in at an eye-watering £1,300 – 2,500.

Heat-only and regular boilers are typically between £500 and £2,500 unless you opt for a biomass boiler. Biomass boilers are a type of investment as they come in at £7,000 to £15,000.

Now, consider this; these prices are boiler-only. However, you still need to consider the cost of Gas Safe Installation.

Labour Cost For The Actual Installation

How much labour is required will determine the final cost of your installation. Where you are located, the provider you choose, and how many specialists are required to install the unit will all determine the costs involved.

That said, we can work on averages and currently, the cost of labour for a new installation is between £500 and £1,000.

Why does the cost vary so much? Because there’s a lot to consider. Combi swaps typically take a day to complete, whereas a back boiler conversion will take around two days. Labour costs for conversions can be between £1000 and £1,500.

Cost Of The Vertical Flue

A large pipe leads from the boiler to the outside world called a boiler flue. The pipe is quite a nifty feature as it ensures gases and condensation are sent outside and not into the home.

If the flue exits the home horizontally, you won’t expect to pay any additional charges. Still, if the flue happens to leave your home vertically (as in, through the roof), you can expect additional charges during installation between £300 and £600.

The Cost Of A Plume Kit

If your boiler’s flue is too close to your window, the door or even your neighbours, you will need a plume kit which is an extension kit.

You cannot have your flue too close to neighbours, doors, and windows, and this is according to Gas Safe regulations (by law). A plume kit can cost between £90 and £130.

Upgrading The Main Gas Pipe

Older heating systems sometimes spot 15mm gas piping, whereas modern standards dictate that pipes should be 22mm.

Lead pipes must be replaced with copper piping, and the labour can cost anywhere between £250 and £400.

Are There Other Costs Too?

Hidden costs can be a nightmare, especially when they secretly rack up and you’re left with the hill in the end.

Ensure that you ask about the possible additional costs with the installer before you sign a contract or give the go-ahead for work to begin. 

Additional costs can be incurred, such as relocating the boiler, which results in other fixtures, fittings, and pipework. Also, if you want any upgrades to your heating controls, you can expect up to £300 in additional costs.

One cost that many homeowners find worthy is the extended warranty. Most opt for a 10-year warranty but make sure that you only get this from a manufacturer or their official partners.

Lastly, magnetic boiler filters that can protect your boiler by trapping small dirt and metal particles will cost you around £200 whereas a chemical flush that can help “deep clean” your system will set you back around £150.

Is it starting to make sense why boiler installation costs in 2022 vary so greatly?

New Boiler Costs Final Thoughts

When considering a new boiler installation cost, don’t assume that the labour cost of installation is included in the quoted price.

Often, the cost is merely for the boiler, and you will have to consider a variety of additional costs according to your needs.

It’s a good idea to chat to a professional about the various brands on the market before assuming that cheaper options are of poor quality – this isn’t always the case.

The most common type of boiler installation is a straightforward combi swap in the UK, but if your requirements are different, chat to a professional in the industry about your needs before settling on a new boiler that you know little to nothing about.
