Is your old gas boiler causing your energy bills to rise up? Nobody likes the extra expenses added to their wallet by an inefficient boiler. However, there is some good news. Upgrading to a new energy-efficient boiler doesn't have to hurt your pocket. With a number of government grants for gas boiler replacement, you now have the chance to have a warmer house with less money spent on energy bills. Learn how you can take advantage of these boiler grants to make the smart decision concerning your home and wallet today. Below, you will be presented with the best boiler grant options to upgrade your boiler in 2024.
Signs It's Time to Replace Your Boiler
Most gas boilers survive and function between 10 to 15 years; some begin losing efficiency much earlier than this. Needless to say, constant servicing is essential to give one's gas boiler a longer life. It is normal to see some boilers lasting 30 years with constant servicing, but usually after 15 years, it's time to have your boiler upgraded with a new and more efficient model. Following are the indications that you need to replace your gas boiler:
- Frequent Breakdowns: If your boiler has broken down and is under 7 years old, it's probably worth calling an engineer to repair it for you. If, however, it is older and breaks down frequently, a boiler replacement is the most cost-effective option.
- Rising Energy Bills: Over the years, boilers inevitably drop in efficiency. It means they require more effort to generate the same amount of heat. More strain on the system translates into higher energy bills. Whereas an older G-rated boiler is 70% efficient or less, new A-rated ones have an efficiency of higher than 90%. Upgrading to a new boiler can save you roughly £300 every year on your energy bills.
- Unusual Noises: If your boiler produces new unfamiliar noises, especially the vibrating kind, then it likely portrays an issue. In case you have a boiler older than 10 years, the cost of repairs outweighs keeping them in use. Here, it will be advisable to get a new energy-efficient one. This will ensure that you cut down expenses in future repairs and on your power bills.
- Yellow Flame: A healthy boiler must have a blue flame. When it turns yellow or orange in colour, that would likely be a carbon monoxide leak and needs immediate attention.
- Water Leaks: Visible leaks around the boiler mean that some internal component of your boiler is broken. If left unfixed, it can even cause structural damage to your home.
- Problems with the Pilot Light: The pilot light is an important part of your boiler. If it goes out, it usually has something to do with the thermocouple. It is essential that you ensure your pilot light doesn’t go out so your boiler operates efficiently.
- Strange Odours: When you have an eggy smell coming from your boiler, this is often indicative of a gas leak. It's a very serious problem and needs your immediate attention. Call this National Gas Emergency line: 0800 111 999.
- Replacement Parts Are Difficult To Get: In case the parts for your boiler are reaching the point of becoming obsolete/discontinued or very hard to get, it would make more sense to invest in a new unit.
New Boiler Costs in the UK

The price of a new boiler changes with the chosen type, brand, and size, but the average cost ranges from £1,500 to £5,000. When you add installation, it may go up to £10,000.
Here's a detailed breakdown of the average costs for different types of boilers:
Boiler Type | Cost (Excluding Installation) | Installation Cost | Total Cost (Including Installation) |
---|---|---|---|
Combi Boiler | £500 - £3,000 | £500 - £1,000 | £1,000 - £4,000 |
System Boiler | £600 - £3,500 | £600 - £1,500 | £1,200 - £5,000 |
Conventional Boiler | £700 - £3,500 | £700 - £1,500 | £1,400 - £5,000 |
Electric Boiler | £600 - £2,500 | £600 - £1,500 | £1,200 - £4,000 |
Biomass Boiler | £5,000 - £12,000 | £2,000 - £8,000 | £7,000 - £20,000 |
There's no need to be afraid of the prices. There are plenty of free boiler grants in 2024 that offer partial or full funding for eco-friendly boilers and other energy-efficient measures, such as insulation and solar panels.
Am I Eligible for a New Gas Boiler Grant in 2024?
Getting a new gas boiler in 2024 is absolutely possible; it's more affordable than one would think, all thanks to the government grants available. For instance, the ECO4 scheme offers a valuable opportunity for most UK homeowners and even tenants to change their old heating systems without breaking a bank.
ECO4 doesn’t just give away free boilers; it is an initiative toward a greener life in every household in the UK. Here is the key detail: for one to qualify for a gas boiler grant, the new boiler should be a condensing gas boiler, while your existing one must be a non-condensing boiler. Why? This is because condensing boilers are far more energy-efficient, reducing your heating bills and carbon emissions.
Non-condensing boilers lose a large amount of heat when they operate and their efficiency can run as low as 50% in earlier models, and 70-80% at best in newer ones. Condensing gas boilers remarkably reduce heat loss and increase efficiency up to 95%. Some particular designs even have efficiencies of 99%, making them a superior option for reducing your energy bills and lowering your carbon footprint.
Advantages of Condensing Gas Boilers: Efficiency, Savings, and Environmental Benefits

Higher Efficiency: Condensing gas boilers have an exceptionally high efficiency, reaching 95-99%, meaning more heat is utilised and less energy goes to waste. Non-condensing boilers operate at an efficiency of only 70-80%.
Lower Energy Bills and Long-Term Savings: Condensing boilers are more efficient and require less fuel to produce the same amount of heat. This results in about 23% less energy bill cost compared to condensing gas boilers.
Less Carbon Emission: Condensing boilers work more effectively with fuel to give out less carbon emissions, thus being more eco-friendly. It is possible to reduce your personal carbon footprint by up to 1,200 kg annually just by replacing your current boiler with a condensing gas boiler.
Better Value of Property: Installing a high-efficiency condensing boiler adds more value to your building and therefore attracts more buyers.
Compliance with Regulations: Some regions have laws that are necessitating or requiring the use of high effective heating equipment. By installing or replacing your old boiler with a new condensing boiler, you meet all regulations no matter where you live or what new regulations are to come.
Noise Levels: Because of their design, today's condensing boilers are much quieter compared to older boiler systems. As such, they result in an improved living environment away from all the noise caused by older boilers.
Advanced Features: Condensing boilers generally have advanced features such as programmable thermostats, remote control options, and diagnostic systems to ensure better control and convenience.
By upgrading to a condensing gas boiler, you’re killing two birds with one stone—improving your home's heating efficiency and going green to ensure a cleaner environment.
Energy Company Obligation (ECO4)
Since the scheme launched back in 2013, and now in its fourth phase called the ECO4, huge savings have been achieved, equating to £20 billion lifetime bill savings for UK households. The scheme has completed more than 3.6 million energy-efficient upgrades across over 2.4 million UK homes, with wall insulation being the most popular improvement.
With ECO4, many different energy-efficiency measures—insulation, boiler upgrade, boiler repair, even green heating system installations—can be partially or fully funded. Join millions of other UK homeowners now reaping benefits from the ECO4 scheme and reduce your energy bills while contributing to a greener planet.
ECO4 Boiler Grant: Eligibility Criteria and Application
ECO4 is a scheme running until 31 March 2026 supporting low-income and vulnerable households. To get a grant under ECO4 for a new gas boiler, one needs to be on specific benefits—income-related Universal Credit or Child Tax Credit, for instance.
If you do not receive these benefits, you may still qualify under the ECO4 Flex Scheme. Eligibility includes either households with an overall income of £31,000 or less, or households with a member who has a health problem that makes them vulnerable to cold.
Please refer to our comprehensive guide to Free Boiler Grants in the UK 2024 for more information about eligibility criteria.
