How Much Does a New Boiler Cost in 2022?

Finding the right new boiler for your home doesn’t need to be difficult or costly. Depending on the system, a new boiler can cost anything between £500 - £3,000. 

As of April 2022, energy bills for the average UK household will increase by 54%. Replacing your old boiler will reduce this cost and could save you up to £365 per year.

Homes in the UK can also benefit from a wide range of grants to cover the costs of upgrading your heating system. This includes the Warm Nest scheme by the Welsh government which offers free boiler replacements, and the recently renewed ECO Scheme. Find out more in the grants section below.

New Boiler Costs in the UK

How much a new boiler costs will depend on many factors such as the type, size, performance, brand and warranty length.

New Boiler Price Range
Boiler Types Price Bands
Combi Boiler £500 - £2,000
Condensing Boiler £1,300 - £2,500

Biomass Boiler £7,000 - £13,000
Electric Boiler £1,500 - £2,500

While the upfront costs of a new high-performance new boiler can be expensive, they are a great investment for the following reasons: 

  • Improve your overall energy efficiency by 30%

  • Longer lifespan and eco future proof

  • Require less maintenance and running costs per month

To find the most efficient boiler that suits your home’s specific needs, you will need to compare deals offered by the top suppliers in your area. This will help you make an objective decision and you’ll benefit from competitive prices.

New Boilers - Cost-Efficient Options for Your Home

The most affordable boiler for most UK households is a new combi boiler, costing £500 - £3,000; or a conventional boiler, which costs £500 - £1,500.

When looking for a new boiler one of the most popular options in the UK is the electric combi boiler. These can cost between £1,500 - £4,500. The electric combi is environmentally friendly as it does not release any gas into the atmosphere. 

All combi models do not include hot water storage or cold water tank, making them perfect for smaller homes with little space. This also makes them cheaper to install and maintain than most other boilers.

The oil-fired combi boiler is a popular alternative to gas in the UK, costing £1,000 - £2,800. New models have an energy efficiency of up to 95%, although frequent maintenance is essential. 

What’s more, oil prices can be unpredictable. As Russian oil exports slow down due to international sanctions, the inevitable swerve away from oil and gas is sped up.

When is it time to replace your boiler? 

Ideally, you should replace your boiler after 10-15 years. There are many ways to identify an outdated or faulty boiler at the end of its life:

One or more of these factors can cost you significant energy and money. So, if you notice any of these warning signs, it’s time to replace your boiler.

How Much Does a New Boiler Cost to Install?

The average installation cost of a new boiler in the UK is £550 - £2,500. 

A good rule of thumb for a new boiler’s installation cost is that the more straightforward the job is, the cheaper it will be. 

New Boiler Installation

Installing the same type of boiler in the same place will often cost less, based on the condition of your existing systems and fittings. 

Costs can also change significantly if you are converting to a new type of boiler, or if you are installing the boiler in a different location to your old one. Upgrading your pre-existing systems and fitting the new type of boiler will mean some additional costs.

New Boiler Conversion Costs

Perhaps most important in keeping costs down is choosing the right installer for the job. A national company like British Gas will not offer the most cost effective service since it operates on a much larger scale than a sole trader. 

It is important to find a reputable company by comparing the best options in your area. That way, you can choose between tailor made quotes that reflect your actual needs!

What New Boiler Is Right for Me?

Combi Boiler

Combi boilers take water directly from the main lines and provide hot water on demand. They are an environmentally-friendly option as they don’t release any gas. They are compact and do not require additional water units, making them perfect for smaller homes with one bathroom.

Combi Boiler Facts
  • Price range: £500-£3,000
  • Fuel type: Gas, electric, oil or LPG
  • Water storage: Connected to mains
  • Recommended home size: Smaller homes & apartments
  • Water pressure: Weak if multiple taps are used
New Combi Boiler

Conventional Boilers

A conventional boiler is an excellent option for larger homes. Conventional boilers are composed of two water cylinders, one for heating the water and a second for storing the water for usage. The two-cylinder system is excellent for maintaining water pressure when multiple taps are being run due to the abundant storage space.

Conventional Boiler Facts
  • Price range: £500-£1,500
  • Fuel type: Gas or oil
  • Water storage: Water cylinder
  • Recommended home size: Mid-sized homes
  • Water pressure: Good water pressure for multiple tap use
New Conventional Boiler

System Boilers

A system boiler heats water straight from the main lines. Like conventional boilers, they store hot water in a storage tank allowing for more than one hot water outlet. This makes them great for homes with high water demand. They are more spatially efficient than conventional boilers since they only require one water storage tank.

System Boiler Facts
  • Price range: £1,000-£2,500
  • Fuel Type: Gas, oil or electric
  • Water Storage: Mains or water cylinder
  • Recommended home size: Mid-large-sized homes
  • Water pressure: Good water pressure for multiple tape use
New System Boiler

Biomass Boilers

Biomass boilers work by burning wood pellets, chips or logs to produce energy to heat water. This sustainable fuel source is cheap to obtain, saving you 30-50% on fuel consumption each year. New biomass boilers are on the expensive side, but the UK government offers grants to those who meet the criteria.

Biomass Boiler Facts
  • Price range: £7,000-13,000
  • Fuel type: Biomass
  • Water storage: Water cylinder
  • Recommended home size: Mid-sized homes
  • Water pressure: Good water pressure for multiple tap use
New Biomass Boiler

Electric Boilers

Electric boilers are compact, easy to install and maintain. They are highly energy efficient making them one of the best new boilers for the environment. On the downside, monthly costs are higher than other boilers.

Electric Boiler Facts
  • Price range: £1,500-£2,500
  • Fuel type: Electric
  • Water storage: Mains or water cylinder
  • Recommended home size: Small-mid-sized homes
  • Water pressure: Dependant on the type of boiler

What Grants Does the UK Government Provide for New Boilers?

The UK Government has established many energy-saving initiatives for UK households to help cover the costs of new boilers and renewable heating appliances

Warm Home Nest Scheme 

The Welsh Government will provide households with a free boiler, central heating system, insulation or solar panels (subject to eligibility). 

Eco Company Obligation

The recently renewed Energy Company Obligation (ECO4) scheme will come into full force on 30 June 2022.  

This scheme obligates suppliers to help low-income, fuel poor households with upgrading their boilers and heating systems. This includes free boiler replacements.

The government will replace up to a maximum of 5,000 broken boiler and electric storage heating systems per year. Inefficient heating system upgrades will not be subject to a cap. 

Some of these criteria include receiving income-related benefits. Your boiler must also be at least 5 years old to qualify for the grant. 

An estimated 3.5 million homes are eligible for the new scheme.


Boiler Upgrade Scheme 

Under the Boiler Upgrade Scheme, the UK government has announced £5,000 grants for people who will install low carbon heating systems, such as heat pumps. The £450 million initiative will run for three years from April 2022, in England and Wales. 

Through the Heat and Buildings Strategy, the UK Government aims to phase out fossil fuel boilers by making it easier to upgrade to clean energy. An additional £60 million will be invested in making clean energy installations cheaper and easier to maintain. 

Find out if you meet the eligibility requirements here.


Gas boiler ban- latest from the UK government!

The UK government has announced that gas boilers will be phased out to meet the Net Zero by 2050 target. From 2025, new homes will not be fitted to the gas grid, then by 2035 gas boilers will be banned from the market. 

This ban means that now is the best time to upgrade to an energy-efficient boiler!

Find the Right New Boiler for Your Home in the UK

Be sure that you find the right boiler by considering the size of your home, your water demands and the structure and pipework of your current system. 

Be aware of the ongoing maintenance requirements and fuel type to determine running costs. 

Once you know which boiler your home needs, you will have a better idea of the installation and potential conversion costs. 

Then, it’s time to compare local installers to determine who can offer the best service.
