Over 6 million households in the UK have fallen victim to fuel poverty, depriving them from keeping their homes warm during the winter, vastly due to the ever-rising running costs of oil boilers.

To combat this growing issue, the UK government has released oil fired boiler replacement grants under the prestigious ECO Scheme, to bring low-income families free funding to replace their oil boilers for new alternatives: air source and ground source heat pumps.

In addition to heat pumps, the oil boiler replacement grants also bring qualifying households additional upgrades such as solar panels, loft and wall insulation, storage heaters or radiators, and heating controls, all for free or at a massively discounted price.

If you are amongst the victims of fuel poverty and you’d like to upgrade your home heating system, you can apply for this exclusive grant at FreeBoilerGrantsUK.com for free now.

What Are Oil Fired Boiler Replacement Grants?

They are government-backed grants that bring free funding to low-income families in England, Wales and Scotland whose oil boilers are faulty, inefficient or older than 7 years, in order to combat fuel poverty, a problem that affects over 6 million households in the UK.

These grants bring qualifying households the opportunity to replace their existing oil fired heating systems with innovative and energy-efficient alternatives such as air source and ground source heat pumps, and biomass boilers.

Furthermore, because the grants receive an important allocation from the ECO Scheme’s budget of £1 billion for 2024, they also include additional upgrades such as expert fitting, insulation, solar panels, storage heaters, radiators and heating controls.

Because this grant is exclusive for low-income households, it also offers free online application, property survey and installation, in addition to all the replacements and upgrades that qualifying properties will receive.

What is the Energy Company Obligation Scheme?

The Energy Company Obligation Scheme, also known as the ECO Scheme, is a government initiative to combat key problems such as fuel poverty and environmental contamination by placing an obligation on energy companies in England, Wales and Scotland to provide energy-saving solutions to qualifying low-income households.

Therefore, companies such as E.ON Power, EDF, British Gas, Scottish Power and SSE are actively helping low income families to upgrade their energy and heating systems, to allow them save money and reduce their carbon footprint.

Amongst these solutions we find the oil fired boiler replacement grants, an access to free funding to replace oil and gas powered boilers for environmentally-friendly and energy and moving saving alternatives such as air source heat pumps, ground source heat pumps and biomass boilers.

As a result, the government aims at making all households more energy efficient and eco-friendly by 2035. Therefore, they have budgeted £1 billion for 2024, from which an important allocation is going towards oil boiler replacement grants.

For the present year, the ECO Scheme has turned into the ECO4 Scheme, which in comparison to the previous year - ECO3 for 2023 - and it has placed a greater focus on helping the most vulnerable households in the UK, such as families with a household income lower than £31,000, who suffer from a health condition or receive a qualifying income benefit.

The application process is available for everyone and it’s 100% free - bringing you the opportunity to make your home a better place to live while saving money on energy bills.

Who is Eligible for Oil Fired Boiler Replacement Grants?

Find out if you are eligible for claiming this ECO-backed grant by checking its eligibility criteria and requirements.

Household Location

Because the oil boiler replacement grants are part of the ECO Scheme, they are only available for qualifying households in England, Scotland and Wales.

Household Ownership

The grants are only available for homeowners and private tenants. If you are renting a property and you qualify for this grant, we recommend you communicate this to your landlord in order to claim the free funding and upgrade the property.

Household Income

The current phase of the ECO Scheme, which is ECO4 for 2024, has placed a greater focus on helping low-income households, and therefore only families with a household income lower than  £31,000 can claim oil boiler replacement grants.

However, there are exceptions to this rule such as households who receive at least one qualifying benefit or who suffer from a health condition. You can find more details about this in the next two sections.

Household Benefits

If someone in your property receives an income benefit from the following list, you might qualify for a grant to replace your boiler:

  • Income-based Job Seeker’s Allowance
  • Income-related Employment Support Allowance
  • War Pensions Mobility Supplement
  • Attendance Allowance
  • Disability Living Allowance
  • Child Benefit
  • Personal Independence Payment
  • Ministry of Justice Benefits
  • Armed Forces Independence Payment
  • Constant Attendance Allowance
  • Pension Guaranteed Credit (excludes Savings Credit)
  • Industrial Injuries Disablement Benefits
  • Severe Disablement Allowance
  • Working Tax Credit
  • Universal Credit
  • Child Tax Credit
  • Income Support
  • Carer’s Allowance

Even if the household income is more than £31,000 per year, being a receipt of income benefits can make you eligible for claiming free funding from the ECO4 Scheme under the modality of boiler replacement grants.

Household Health Conditions

If someone in your property suffers from a qualifying health condition from the following list, you might qualify for an ECO4 grant:

  • Diabetes
  • Arthritis
  • Asthma
  • Limited mobility
  • Immunosuppression
  • Cardiovascular conditions

However, it’s important to know that the health condition or long-term illness must be verified by one of the following entities:

  • General medical practitioner
  • Health Board
  • NHS Trust
  • Local Health Board
  • NHS Foundation Trust

Even if the household income is over £31,000 per year, this exception will make your property eligible for claiming an ECO4 grant to replace your boiler and install additional upgrades such as insulation and solar panels.

Household EPC Rating

A deficient EPC rating is an important eligibility factor because it measures the energy efficiency of your property. Therefore, an EPC of D, E, F or G is necessary to qualify for the oil boiler replacement grants from the ECO4 Scheme.

To put this into perspective, let’s define the efficiency rate of each EPC rating:

EPC Rating

Efficiency Rate


92% to 100%


81% to 91%


69% to 80%


55% to 68%


39% to 54%


21% to 38%


1% to 20%

The efficiency rate of properties rated with an EPC of D, E, F or G is notoriously deficient because it shows they are consuming energy unnecessarily, hence contributing to residential energy consumption and greenhouse gas emissions.

Because they are deficient at spending and administrating energy, such buildings put low-income households at risk from being victims of fuel poverty. This is another reason why the oil boiler replacement grants are available to private tenants as well.

Household Existing Boiler

As it’s evident, this grant is only available for properties which existing boiler meets the following criteria:

  • It uses oil, gas or LPG to work (combustion)
  • It is 7 years old or more
  • They are faulty and consume energy unnecessarily
  • They are the reason why your property is rated with an EPC of D, E, F or G
  • It’s beyond the point of repair (it doesn’t make sense economically to restore it)

Having a boiler like this at home puts households at a higher risk of fuel poverty, and hence the ECO4 Scheme is only available for families who need immediate help to replace their boiler for a more efficient and eco-friendly option.

What Does an Oil Boiler Grant Include?

Explore all the upgrades and solutions that oil fired boiler replacement grants offer you thanks to the free funding from the ECO Scheme.

Heat Pump or Biomass Boiler

Claiming the oil boiler replacement grant will offer you three options for replacing your existing heating system:

  • Air Source Heat Pump: It is a heating and cooling system that transfers heat between indoor and outdoor air. It efficiently extracts heat from the outside air during winter to warm indoor spaces and reverses the process in summer for cooling - it works without combustion and hence it’s a solid alternative to oil boilers
  • Ground Source Heat Pump: It’s a home heating solution that uses the stable temperature of the earth to heat a building during the winter, and cool it during the summer just like air source heat pumps
  • Biomass Boiler: It is a heating system that combusts organic materials like wood pellets, chips, or agricultural residues to produce heat. It operates similarly to traditional boilers but utilises sustainable fuel sources, making it eco-friendly and a solid choice for reducing carbon emissions

They’re up to 70% more efficient than traditional oil and gas boilers, hence they will do a better job at keeping your home warm during the winter and helping you save money on energy bills.

Furthermore, they generate far less carbon emissions than oil boiler, as shown in the following table:

Type of Home Heating

Carbon Emissions Per Year

Oil Boiler

5,200 KG

Air Source Heat Pump

850 KG

Ground Source Heat Pump

850 KG

Biomass Boiler

2,600 KG


As it’s evident, heat pumps are the best options, hence biomass boilers are only reserved for very specific situations when installing a heat pump is not a viable option.


Because loft and wall insulation can help homeowners save up to 50% on utility bills, it’s another upgrade you can claim thanks to the oil fired boiler replacement grant. They will further increase the efficiency of your home, so you can keep it warm during the winter and fresh during the summer at a much lower cost.

Solar Panels

Solar panels can help you reduce your energy bills by a large margin, especially during the winter when your radiators and storage heaters will be working at a higher rate. This is why the oil boiler replacement grants can also include the installation of solar panels, to make your home even more efficient.

Storage Heaters

The oil boiler replacement grant can also help you replace your existing storage heaters for modern storage heaters with a higher heat retention rate and higher efficiency. Hence, they’re able to charge heat faster and retain it for longer, and since they charge during off-peak electricity times, they will help you save more money thanks to the Economy 7 and Economy 10 tariffs


An alternative to storage haters are radiators, and in case the specialists determine during the free property survey that they are a better choice, then the grant will bring you free funding for installing them.

Heating Controls

The grant will also bring you free funding for installing modern and easy-to-use heating controls. You will have full control over the heating and cooling of your property, to keep it in perfect condition for you and your family.

Expert Fitting

From the heat pump or biomass boiler to the insulation and solar panels, the grant will also include expert fitting to make sure all the upgrades are properly installed. The ECO4 Scheme only works with reputable, licenced and professional heating and energy suppliers and specialists.

The Advantages of Oil Fired Boiler Replacement Grants

Applying for a government grant to replace your oil boiler offers a series of benefits from saving money on utility bills to improving your home comfort. Here you have the full list of advantages on why it’s an excellent idea to claim this grant today.

Save Money on Utility Bills

Oil fired boiler replacement grants will bring you the opportunity to replace your old heating system for innovative and energy-efficient options such as air source and ground source heat pumps. When compared to traditional boilers, they can help you save up to 70% on utility bills every year.

Improve Your Home Comfort

Not being able to keep your home warm during the winter because you cannot afford it is a situation that strikes over 6 million households in the UK. Fortunately, thanks to this new grant under the ECO4 Scheme, now you can combat fuel poverty and keep your home warm and comfortable throughout the winter thanks to new heating solutions such as air source and ground source heat pumps.

Bring Relief to Health Conditions

Cold air is known for triggering asthma, and low temperatures will thicken the synovial fluid, worsening the symptoms of arthritis. Hence, not having a properly heated home during the winter puts people who suffer from these health conditions at serious risk.

This is why it’s an excellent idea to apply for the oil boiler replacement grant today, because if someone at home suffers from these or other health conditions, you’ll be able to bring them the relief they crave by keeping your home at the right temperature throughout the day.

Prepare Your Home for the Summer

The new grants will allow you to replace your oil or gas boiler for heat pumps, and their biggest advantage is that they will also make your home a comfortable place during the summer. Because they can bring conditioned air into your property, your house will remain fresh even during the hottest summer days. If you have an alternative heating system in your property you can still apply for the scheme. Read This Article for more information.

Get Peace of Mind

Alternatives to oil and gas boilers such as air source and ground source heat pumps do not require regular maintenance or safety checks. Because they do not use combustion, they are much safer options and they will bring you the peace of mind you need to sleep well at night, knowing your family is safe.

The Running Costs and Carbon Footprint of Oil Boilers: Why It’s Worth It to Replace Them

Let’s go beyond the personal benefits of replacing your old boiler. In this section, we are going to explore the running costs and carbon footprint of oil boilers, to let you see how opting for this grant will contribute to helping the planet.

Oil Boilers Running Costs Are Expensive

The average running cost of an oil boiler is £1,880 per year, and this can vary dramatically depending on the price of oil, which can be highly influenced by external factors such as wars and shortages. For example, shortly after Russia’s invasion of Ukraine, thousands of households had to pay bills over £800 due to their oil boilers.

This is why it’s a good decision to replace your oil boiler with a heat pump or biomass boiler, because the average running costs for these alternatives ranges from £800 to £1,000 per year, and by installing additional upgrades like extra insulation, you can reduce the price even more.

Claiming an oil boiler replacement grant will upgrade your home heating system and protect it against external factors, bringing you more control on your utility bills and how you heat your home.

Oil Boilers Are the Most Contaminant Type of Home Heating

An oil boiler is estimated to generate 5,200kg of carbon emissions every year, making it the most contaminant type of home heating in existence. Alternatively, the heat pumps from the oil boiler replacement grants only generate 850kg of carbon emissions per year.

Oil Boilers Are Going to be Banned in the Future

Did you know that the UK government is planning to ban oil and gas boilers by 2035? This is one of the measures they are going to take to reach net zero carbon emissions by 2050, and hence it’s a good idea to take action as soon as possible to replace your existing home heating system.

Waiting until several years later to take action will prove to be a bad decision, because now you can claim grants to get free funding to replace your oil boiler, and there is no guarantee the government will keep offering these incentives the next few years.

Therefore, the best action you can take now is to apply for this grant at FreeBoilerGrantsUK.com - because the process is fast and 100% free.
