New Boiler Cost in UK
The new boiler cost has increased in 2024, bringing harsh reality to British homeowners. For many Britons, this significant increase coincides with rising energy prices, creating a financial double burden.
New Boiler Cost (Exc. Installation)
- Combi Swap £600 – £2,000
- System Boiler £500 – £2,500
- Conventional Boiler £600 – £3,500
- Electric Boiler £600 – £2,500
- Biomass Boiler £7,000 – £15,000
New Boiler Cost Cost (Inc. Installation)
- Combi Swap £1,500 – £3,500
- System Boiler £1,700 – £3,600
- Conventional Boiler £1,700 – £3,000
- Electric Boiler £1,700 – £3,500
- Biomass Boiler £10,000 – £18,000
The kind and complexity of installation can affect the new boiler cost. Installing a gas boiler requires a Gas Safe licensed heating engineer, therefore installation expenses must be considered as well.
New Boiler Installation Cost
A new boiler cost is determined by a number of variables, such as:
- The cost of replacing a boiler, including the type and brand you want to use.
- Boiler type: combi, system, or ordinary, etc.
- The boiler’s dimensions.
- If you would like to relocate your heater.
- The cost of labour in your region.
Should you wish to switch from one kind of boiler to another—for example, from a combi to a system.
and any accessories, such as radiators, high-end magnetic filters, and smart controls.
All things considered, a simple combi change is the most common and usually the least costly.
Cost of a Combi Boiler
A combi boiler is a kind of boiler that uses one system to supply hot water and heat the entire house. It is therefore ideal for modestly sized dwellings with low heating requirements.
What does a new boiler cost, then? The average cost of a new combi boiler is between £500 and £3,000. But bear in mind that this does not include the cost of installing the combi boiler. When you’re computing your overall budget, account for this.
- Combi cost (excl. installation): £500 – £3,000
- Combi cost (Est. installation): £1,500 – £4,500
The manufacturer, model, and fuel are only a few of the variables that affect the price of a new combi boiler. Your home’s size and energy needs are also important considerations.
You also need to think about your particular boiler replacement scenario. These are average boiler replacement expenses:
- Situation of replacement cost estimate
- The new combi boiler was installed in its place, replacing the old one.Between £500 and £3,000
- New combi boiler installed in lieu of the system boiler£3,500 – £580
- New combi boiler installed in place of regular boilerBetween £600 and £3,500
The price to convert a conventional boiler to a combi boiler
- Consider switching to a new combi boiler in place of your traditional boiler if you need to make space or cut energy costs.
- Numerous advantages come with a combi boiler, including great efficiency, low maintenance requirements, and a far more practical size. After the large water tanks are removed, you could even convert the loft.
- Nevertheless, even though combi boilers save energy expenses and save space, you may have to give up the necessary warmth and comfort for your household if your home is too big for a combi boiler. Remember this.
Even while choosing such a replacement is often more affordable, there are additional expenses involved:
Service Charges
- Cost to remove the hot water storage cylinder: £150 to £150
- Cost: £200–£300 for the removal of the expansion tank and feed
Converting from a traditional boiler to a combi boiler may be more expensive, but it’s frequently a beneficial investment.
Your new boiler should cost between £1,900 and £3,950 when the boiler replacement cost is added to these other expenses. The cost of a new combi boiler plus installation and replacement adds up to £3,500 to £7,450.
Cost of a Conventional Boiler
A cold water cistern located in the attic or loft with a feed and expansion tank make up a traditional or conventional boiler. It also needs a hot water storage cylinder, which is typically kept in an airing cupboard. A conventional boiler’s price is determined by the following:
- Warranty for Brand, Model.
- Cost of installation.
- Size of the property.
- Conventional boiler cost excluding installation is £600-£3,500£.
- Including Installation is £1,700–£4,000.
Benefits of a Conventional Boiler
- Suitable for larger homes because it can concurrently serve many bathrooms with ample amounts of hot water.
- An immersion heater can be installed in the hot water cylinder to provide hot water as a backup.
- Facilitates simultaneous use of hot water by numerous persons.
The Shortcomings of a Conventional Boiler
- Needs enough room to accommodate the boiler, the hot water cylinder, the header tank, and the cold water storage tank.
- Low pressure flow for hot water and showers could arise from this.
- Does not deliver hot water instantly.
- Needs more room in order to accommodate the tanks, cylinder, and boiler.
- Not advised in places with inadequate local water pressure.
Cost of the System Boiler
A storage cylinder is used by a system boiler to supply heat to the hot water and central heating systems. A new system boiler should cost you between £580 and £3,500. Additionally, you can be assessed boiler fitting fees ranging from £1,580 to £5,000.
We need to consider a few more things in order to determine the system boiler cost and replacement cost. When selecting your system boiler, the manufacturer, type, and fuel are important considerations.
However, other factors that affect system boiler costs include property size, energy requirements of the house, system boiler efficiency rating, and system boiler warranty duration.
New Boiler Cost by Model and Fuel type
The average cost to install a new boiler in a UK home is between £1,500 and £5,000. Boilers can range in price depending on the size and type that are needed. Combi boilers, for instance, can be purchased for between £500 and £3,000, conventional boilers for between £600 and £3,500, and system boilers for between £580 and £3,500.
Boilers are no different, and they are available in a range of forms and pricing points. Let’s examine what you should budget for in more detail.
Combi Boiler
- Budget Models: £500-£900
- Mid-range Models: £900-£2,000
- Premium Models: £2,000-£3,000
System Boiler
- Budget Models: £580-£900
- Mid-range Models: £900-£2,500
- Premium Models: £2,500-£3,500
Conventional Boiler
- Budget Models: £600-£900
- Mid-range Models: £900-£2,500
- Premium Models: £2,500-£3,500
Lastly, the new boiler cost of installation is affected by the fuel your new boiler will require. We’ll concentrate on the fuel kinds that are most frequently utilised in the UK:
- Gas
- Oil
- Electricity
We’ll walk you through each one below.
Cost of a New Gas Boiler
A gas boiler is a particular kind of boiler that heats water or steam with gas, warming the home in the process. The most popular type of boilers in the UK are gas-fueled models, which can be used with underfloor heating or radiators.
But what is the cost of a brand-new gas boiler? The average cost of a new gas boiler is between £2,000 and £4,000. Gas boiler installation costs, meanwhile, can reach £4,000 in complicated installations.
- New Gas Boiler Cost (excl. installation): £2,000 – £4,000
- New Gas Boiler Cost ( Est. Installation Cost) : £500 – £4,000
Cost of a New Oil Boiler
In order to heat the home, an oil boiler burns fuel, either oil or diesel. The only difference between an oil boiler and a gas boiler is that the former uses oil to heat and deliver hot water.
One of these units may be purchased for far over £4,000, with oil boiler pricing starting at £1,000. The unit size, manufacturer, and installation expenses all affect the pricing. The overall cost of replacing a new oil boiler, including installation, may range from £2,500 to £4,500.
- New Oil Boiler Cost (excl. installation): £999 – £2,800
- New Gas Boiler Cost ( Est. Installation Cost) : £500 – £1,000
Moreover, the annual cost of operating an oil boiler might be approximately £1,250, which is £250 more than that of a gas boiler.
Cost of a New Electric Boiler
Electricity is used by an electric boiler to heat and provide hot water for household use. Electric combi boilers, electric storage boilers, electric CPSU (Combined Primary Storage Unit) boilers, dry core storage boilers, and solar-compatible boilers are only a few of the varieties of electric boilers available today.
An electric boiler can cost anywhere from £590 to £2,500 on average, depending on the brand, size, and installation difficulty. Furthermore, installation expenses would probably range from £1,600 to £3,500, contingent on your home’s location and heating needs.
- New Electric Boiler Cost (excl. installation): £590 – £2,500
- New Electric Boiler Cost ( Est. Installation Cost) : £1,600 – £3,500
In a normal household, the cost of operating an electric boiler can reach £3,000. Of course, smaller dwellings with one or two bedrooms would have less.
UK Government New Boiler Grants
A number of grants and schemes are currently available from the governments of the UK, Wales, and Scotland to assist households in upgrading their heating systems. The list of those that are now available is below:
ECO4
Energy Company Obligation provides homes with energy-saving upgrades like solar panels, insulation, or a new boiler. A number of factors, including house ownership, benefits, income, and evidence of need, determine eligibility. In Great Britain, the ECO4 is offered by a few local governments and energy providers.
Scheme for Boiler Upgrades (BUS)
Through the Boiler Upgrade Scheme, homeowners in England and Wales can obtain funding to partially offset the cost of installing low-carbon heating systems. The programme offers £5,000 in upfront savings on a biomass boiler or £7,500 in savings on an air source heat pump (ASHP) or ground source heat pump.
0% VAT
Certain energy-saving home solutions are subject to a 0% VAT rate established by the UK government. This covers wood-fuelled boilers, insulation, and air source heat pumps.
Welsh Nest Scheme
The Nest Scheme was developed to assist Welsh householders in increasing the energy efficiency of their homes. In order to end fuel poverty and make houses warmer, it provides free boiler upgrades, insulation, and other renovations. In April 2024, the programme will be modified and changed, and low-carbon technologies will be provided.
Warmer Houses Scotland
This programme provides Scotland’s houses in need of heating upgrades with energy-saving modifications, such as boiler replacements. Although homeowners must fulfil certain requirements, the programme often pays for all necessary work. An interest-free loan is provided to assist with any contributions that could be needed in specific circumstances.
Scotland’s Home Energy Grant and Loan
To assist householders in making energy-saving renovations, the Scottish Government has made interest-free loans and grants available. If certain requirements are met, this could be as much as 75% of the total cost, or up to £9,000.
The Affordable Warmth Scheme (NI)
It provides energy saving measures to low-income households and individuals experiencing fuel poverty in Northern Ireland. Grants are available for home upgrades, including boiler replacements, subject to qualifying and approval.
Please remember that in order to take advantage of these opportunities, you must stay current as grants and schemes are subject to frequent changes. To stay informed, we advise you to visit the websites of your local government.
In Summary, the Average Cost to Replace a Boiler
A new boiler replacement would normally set you back between £1,500 and £5,000.
This includes the price of a new boiler, which often ranges from £500 to £3,500, as well as the usual installation cost of £1,500 to £1,500.
Installations at the lower end of this pricing range will take less time overall, and the boiler can be removed with few modifications to pipework and fittings. These typically entail a boiler replacement that is similar.
But if you’re searching for a biomass boiler, you should expect to pay between £4,000 and £20,000.
