How Much is a New Boiler?

The blog heading surrounded by graphics on the theme of cost and money.

As a leading boiler installation, service and repair firm we often get asked the question “How much does a new boiler cost?”  Although there can be many variables, this question isn’t the same as “How long is a piece of string?”, this is a question which can and should be answered.

So, why does the cost of a new gas boiler vary so much and how do you know whether you’re paying a fair price? Although many things can affect the price of a brand new boiler, none of the reasons are beyond your reach.

At City Warmth, we’re passionate about keeping things simple. So, grab your coffee, get comfy and lets find out how much a new boiler costs.

How Much Does a New Boiler Cost?

How much does a new boiler cost? To cut to the chase, you should expect to pay, on average, between £2000 and £4000.

But why is this price so much more than the list price of a boiler online?

To keep it simple, a boiler listed for £1200 online is just that, a boiler. Alongside the boiler you will need a flue, a filter, some form of heating controller, cleaning and protective chemicals, pipework and (of course) the time and expertise of the person fitting the boiler. Taking these factors into consideration, the price can quickly increase.

But why the wide range of prices? £2000 to £4000 is quite a jump.

How Much to Replace a Boiler in Your Home

You may be wondering how much it costs to have a new boiler fitted. In your home there will be variables that may affect the price of your new boiler installation. For example:

  • Is there a boiler in your home already?
  • Does your home currently have a gas boiler?

Your property may have gas but not a gas boiler. If this is the case there will be many factors to consider, such as where all the pipes currently are, where you would like the boiler located, where the boiler can be located, how many radiators you would like and where they would go etc. So, how much is a new boiler system? Well, the answer to this question depends on the following factors.

The Size of Your Property

One consideration would be the size of your property. For example, if your boiler has been sized correctly, a boiler that supplies heating and hot water to a 2 bedroom flat will cost less than a boiler that supplies heating and hot water to a 4 bedroom detached property. Simply put, the larger the property the more expensive the boiler.

The Location of Your Boiler

Replacing an old non-condensing boiler located on an external wall, on the ground floor near a sink or waste outlet will be cheaper than replacing a boiler in the middle of the property or with a flue exiting through the roof.

The more work involved and the more materials required to replcae your boiler, the more the price will increase.

Your Heating and Hot Water Setup

Do you have a hot water tank in your home? Do you have a back-fire boiler? Do you have a combi boiler? The cost of a new boiler could be affected by the heating and hot water set-up in your home. Not all boiler types are the same. The three main types of boiler are:

  1. Combi boiler
  2. System boiler
  3. Open vent/heat only/conventional boiler

Replacing Combi Boilers

Replacing a combi boiler in the same location is as simple as it gets for understanding the pricing and work involved. The only real consideration may be how close your combi boiler is to a drain or waste water outlet.

Replacing Condensing Boilers

New boilers are condensing boilers. This means they create waste water that needs to be run to a drain as part of their normal operation. If your boiler is nowhere near a drain, a pump could be installed but this would impact the price, as more time and materials would be required to carry out the work.

Replacing Open Vent Boilers

For an open vent boiler replacement you will more than likely need to consider the condensate question, the physical size and the flue location. You may then need to look at your circulation pump. This will typically be a red unit the rough size and shape of an old McDonalds happy meal and probably located in your airing cupboard. If it’s over 10 years old or is covered in a scaly crusty deposit above or below, it will probably need to be replaced alongside the boiler.

New Boiler Controls

Will your new boiler need new controls? Not necessarily but, based on current and predicted future gas prices, you’d be wise to look at having them installed. Payback on the cost of the new controls through gas savings could well happen within a year of installation.

Building Regs Part L requires every new combi boiler installation to have 1 of 4 energy saving features installed at the same time as the new boiler. The 4 options are:

  1. Flue heat gas recovery
  2. Load compensation
  3. Weather compensation
  4. A unit that provides automation and optimisation

At City Warmth, we thoroughly recommend load compensation or weather compensation as the controls to save you the most amount of money on gas usage. We also recommend finding a way to have them installed on new System Boilers and Open Vent Boilers.

For the best returns on your investment, please ensure the weather compensation or load compensation controls are manufacturer specific. If you’re installing a new Baxi boiler, get an ifos (in flue outdoor sensor). If you’re installing a new Worcester boiler, get the Bosch EasyControl. If you’re installing a Vaillant, get the VRC700. Basically, you want to ensure the boiler and controls are made by the same people.

How Much Does a New Boiler Cost in the UK?

So you now know what type of boiler you need, where your new boiler is going to be located and you understand the importance of getting manufacturer specific controls. Now we need to look at the power rating of the boiler, who will be installing your boiler, the boiler make and model, and most importantly what your budget is.

New Boiler Power Rating (kw)

Most of us have heard the phrase ‘heat loss’. Heat loss is how much heat your home loses on an hourly basis through the walls, the windows, the roof and the floor. Your new boiler needs to be able to create enough energy to heat your home without creating excess heat that just gets wasted.

For example, if your home only needs 8kw’s of heat you don’t want to be installing a 24kw boiler. You’re not getting a great deal if Joe Bloggs plumbing will install a 24kw boiler for the same price as our 12kw boiler. You’re getting a worse deal! This is because the extra heat energy created will cost you money and won’t be used.

Top Tip: make sure your chosen gas engineer carries out a heat loss check of your home and doesn’t sell you a boiler that is more powerful than you need. It’ll waste you gas and money in the long term.

Finding the Best New Boiler Make and Model

When it comes to choosing your boiler, you need to do your research. Whichever way we cut it, a new boiler isn’t a ‘cheap’ purchase. Just because one manufacturer is more commonly mentioned than another doesn’t mean it’s the best or the right choice for you.

At City Warmth, we work hard to fit the right boiler in the right home. We look at individual customer factors such as, boiler brand preference, budget limitations, heating and hot water setup, external flue considerations, their needs and preferences, and so much more. When it comes to finding the right boiler for your home and needs, there are many factors to consider.

One boiler does not fit all. That’s why our boiler installation experts are available to guide you through the process and answer any questions you may have.
