Your old boiler needs replacing, but you’re worried about how much a new boiler will cost? That’s usually the foremost question in most UK homeowner’s minds. Considering all factors, a new boiler installation can cost anywhere between £1,500 and £5,000. Quite a big price to pay, but when your old boiler is decidedly inefficient or too costly to service, maybe a new one is the only answer.
Many UK homeowners wonder: How much do boilers cost? What does it cost to fit a boiler? Most importantly, what is the average boiler replacement cost in the UK? The answers will be based on several factors: the type of boiler, the brand, and the complexity of the installation.
So, just how much does a new boiler cost in the UK in 2024? And what are the top brand boiler costs in the UK? In this blog, we’ll cover everything you need to know to help you make an informed decision when the time comes for you to replace your old boiler. Let’s get started!
How Much is a New Boiler in 2024?
The cost of a new boiler can vary depending on many factors, including the boiler type and the installation complexity. In addition to the basic price of a boiler, you will have to pay £1,000 to £1,500 for the installation to a Gas Safe registered engineer.
Here is what can be expected:
Boiler Types | Cost (excl. installation) | Cost (incl. installation) | Average Cost (incl. installation) |
Combi | £500 – £3,000 | £1,500 – £4,500 | £3,000 |
System | £580 – £3,500 | £1,580 – £5,000 | £3,290 |
Conventional | £600 – £3,500 | £1,600 – £5,000 | £3,050 |
Electric | £590 – £2,500 | £1,590 – £4,000 | £2,795 |
Biomass | £4,000 – £12,000 | £6,000 – £21,000 | £13,500 |
The costs are different for each boiler type, depending on brand name, size, and fuel used. For example, a combi boiler would fall in the lower range and be relatively uncomplicated in its setup. At the same time, biomass boilers are pretty expensive due to the complexity and fuel involved.
Average New Boiler Costs in the UK
The average new boiler prices in the UK start from £500 to £3,500, inclusive, depending on the type and brand of boiler selected. However, this price does not include installation costs, which run an additional £1,000-£1,500, depending on the complexity of the job.
In some cases, modern condensing boilers are generally characterised by being smaller. And they can be installed in small spaces. Using the most efficient condensing boilers results in lower energy bills. That helps homeowners save money. Condensing boilers come in three types: combi, system, and standard. All are designed with smart, innovative condensation technology and are made for different home requirements.
Factors That Influence New Boiler Costs
The wide range in costs of boilers can be linked to various factors that influence prices. Some major variables that can affect the cost include:
- Boiler Type: Boilers can be divided into categories based on their usage and other factors. So, their prices vary accordingly: the usual combi boiler, for instance, costs less than a conventional boiler because it doesn’t require a hot water cylinder.
- Complexity of Installation: If it is difficult to access your boiler, you need pipework modification or relocation; your boiler installation cost will be higher.
- Outdated Heating System: This involves upgrading of inefficient old heating systems or those that do not meet gas safety standards.
- Number of Bathrooms: The bigger the house is, especially if there are a number of showers in it, the higher the output of the boiler will be. Hence, the costlier it will be.
- Boiler Relocation: This can increase the price when you need to move the boiler to another location in your house. As it might need more labour, pipework, and materials.
What are the Types of Boilers and Their Costs?
Picking the right type of boiler out of those many alternatives is fundamental to comfort in your home. We break down into three the main types of boilers here, with their average costs and who they could suit best.
Combi Boilers
The combi boiler is popular for smaller homes because it is compact. Heating and hot water appear to be combined in a single compact system with no storage water tanks. They provide instant hot water, making them ideal for homes with low hot water demand.
Combi BoilersHow Much Does a Combi Boiler Cost?
The cost of a new combi boiler can range from £500 to £3,000. However, the installation will be very different and determined by conditions such as the extent of work and the boiler brand. On average, you should anticipate the overall price, including installation, to be around £3,000.

System Boilers
System boilers are ideal for larger homes with high demands for hot water. They use a separate cylinder for hot water. However, the cold water storage tank is not required. This sets them up to be more efficient in properties with many bathrooms.
How Much Does a System Boiler Cost?
A new system boiler can cost between £580 and £3,500, while the installation can cost between £1,580 and £5,000. The price depends on your home’s size, the boiler’s efficiency rating, and how complicated the installation will be.

Conventional (Heat-Only) Boilers
Conventional boilers – also referred to as heat-only boilers – are ideal for larger homes. These houses mainly boast traditional radiator systems, with some available space to accommodate a separate hot water cylinder and a cold water storage tank. They are most commonly used in older properties.
How Much Does a Conventional Boiler Cost?
The cost of a regular boiler starts from £600 and goes up to £3,500, and then another £1,000 is added to the installation. It may even cost more depending on the complexity of the installation.

Overall Boiler Price Ranges for Combi, System, and Conventional Types
The cost of a new boiler can also increase or decrease depending on the type and size required. Each type has a budget, mid-range, and premium model in their respective categories. Here is the price breakdown per model:
Boiler Type | Budget Models | Mid-range Models | Premium Models |
Combi | £500-£900 | £900-£2,000 | £2,000-£3,000 |
System | £580-£900 | £900-£2,500 | £2,500-£3,500 |
Conventional | £600-£900 | £900-£2,500 | £2,500-£3,500 |
Prices can also depend on the brand and energy efficiency. Remember, a higher upfront cost often means better long-term savings due to better efficiency than the cheap ones.
What Does Boiler Replacement Cost Include?
The cost of replacing a boiler costs a lot more than the mere price of the unit. The following are the main factors that contribute to the overall replacement cost:
- Boiler Type: In case one replaces one type for another, say from a conventional boiler to a combi boiler, additional alterations may be required. Hence adding to the cost.
- Replacement Type: Full boiler system replacement may need supplementary parts such as a water tank or piping, while partial replacement requires fewer components.
- Heating Source: Switching to an electric one from gas will reduce some installation costs. But electricity might be costly to operate, depending on your location.
- Boiler Model: Newer, more energy-efficient models may be higher in cost but generally pay for themselves over time in the form of lower utility bills.
- Manufacturer: Different manufacturers will have different prices for the same product.
Other Factors Affecting Boiler Replacement Cost
Price can vary for many factors, including:
- Main Gas Pipe: Upgrading the main gas pipe, if necessary, to take the extra load of your new boiler will surely add to the installation cost. The price depends upon a few factors, such as complexity and location.
- Plume Kit: If the boiler’s flue is closer to a widow or neighbour’s property, a plume kit is needed to redirect the exhaust gases safely.
- Flue Type: Older boilers may have square flues, which also bring additional bricking up or rerouting jobs. For the most part, modern boilers will have round flues. These are much easier and more cost-effective to install.
- Vertical Flue: A vertical flue may be more expensive than a horizontal one due to the complexity of its installation.
Additional Costs | Price Range |
System power flush | £50 – £150 |
Magnetic filter | £100 – £150 |
Thermostatic heat controls | £70 – £650 |
New boiler flue pipe | £50 – £150 |
Cost of Replacing a Conventional Boiler with a Combi Boiler
That would be a good replacement for all those wanting to cut down on energy bills and make homes more efficient. Because combi boilers tend to be more efficient and easier to maintain than their older counterparts.
On the other hand, converting from a conventional to a combi boiler requires extra work, such as restructuring pipework and removing the existing cold water tank and hot water cylinder. Therefore, installation may take about two days, increasing the cost due to labour.
Conventional to Combi Boiler Replacement: Cost Breakdown
- New combi boiler: £500 – £3,000
- Installation costs: £1,000 – £1,500
- Total replacement cost: Around £3,000

New Boiler Costs Breakdown by Fuel Type
The type of fuel a boiler uses determines a great deal of its cost. We discuss herein all these types of boilers in terms of prices to help you decide. These include gas, oil, electric, and biomass.
New Gas Boiler Costs
The most common type in the UK includes gas boilers. They are generally applicable in heating water using gas and, thus, warming your house. They are efficient and most commonly applied with radiators and underfloor heating systems.
Generally speaking, a new gas boiler alone will cost somewhere between £2,000 to £4,000, exclusive of installation costs. Depending on your property and actual needs, the cost of installation can add another £500 to £4,000.
Gas Boiler Cost (Excluding Installation) | Estimated Installation Price |
£2,000 – £4,000 | £500 – £4,000 |
Comparing quotes from different installers is always a good idea to get the best quote for your specific needs.
New Oil Boiler Cost
Oil boilers are also a very popular option if your house is not on the gas network. Burning oil or diesel for fuel provides heating and hot water and is very well adapted to rural homes. A new oil boiler costs between £1,000 and £4,000, excluding installation.
Oil Boiler Cost (Excluding Installation) | Oil Boiler Installation Cost | Total Cost (Boiler + Installation) |
£999 – £4,000 | £500 – £1,000 | £2,500 – £4,500 |
Running costs for oil boilers are slightly higher, at around £1,250 annually, than gas boilers. It makes them about £250 more expensive than gas heating.
New Electric Boiler Cost
Electric boilers represent a greener alternative for homes not connected to the gas grid. Using electricity for heat, they reach an efficiency rating of nearly 100%.
Prices for electric boilers start at £590 and go up to £2,500; installation costs range from £1,600 to £3,500.
Electric Boiler Cost (Excluding Installation) | Total Average Cost (Including Installation) |
£590 – £2,500 | £2,800 |
New Biomass Boiler Costs
Biomass boilers are a greener option for homes with the space to store fuel, like wood pellets or logs. This boiler uses renewable biofuels that provide heating sustainability.
These come with considerably larger price tags – anything from £7,000 to £15,000 for a new biomass boiler.
What Grants Does the UK Government Provide for New Boilers?
The UK government offers many different grants to help with the costs of new boilers and make it easier to install energy-efficient models. There are two main schemes to which you should pay more attention:
Energy Company Obligation (ECO4)
Improvements under the ECO4 scheme include insulation, solar panels, and new boilers. It could also consider eligibility factors like homeownership, income, evidence of need, and receipt of specific government benefits.
This scheme is provided through selected energy providers and other local authorities across Great Britain. For those very low-income families who would qualify, this can be a great option since many eligible households can get a new boiler at no cost.
Boiler Upgrade Scheme (BUS)
You can have support via the Boiler Upgrade Scheme available to offset some of the costs of installing low-carbon heating systems. Homeowners in England and Wales can obtain the following:
- £5,000 off the upfront cost of a biomass boiler.
- £7,500 off of an air source heat pump or ground source heat pump.
The entire scheme is focused on incentivising greener alternatives and reducing the overall carbon footprint from home.
The Bottom Line
In 2024, the cost of a new boiler is expected to range from very high to low depending on various factors with models, makes, and other complications in the installation. UK property owners can, therefore, expect to pay upwards of £1,500 to £5,000 for a new boiler and its installation. Simple swaps cost less, and more complex installations require higher expenses.
Comparing quotes from different providers may help you get quotes for the best investment value. Make sure that you get a reputable Gas Safe registered engineer to do the work.
Grants are available from the UK government. These include the ECO4 and Boiler Upgrade Scheme. These aim to help those who meet the eligibility criteria reduce or alleviate the financial impact of upgrading to a new boiler or low-carbon heating system.
