What’s the Storage Heater Upgrade Grant?

The storage heater upgrade is an ECO4-backed scheme that offers low-income families and households the opportunity to upgrade their old storage heaters with new energy-efficient units with lower running costs and higher heat retention.

It’s one of the most important measures from the ECO4 Scheme to combat fuel poverty because millions of low income households in the UK cannot afford to keep their homes properly heated at a reasonable cost.

Because the new storage heaters from this upgrade charge during off-peak electricity times, taking full advantage of Economy 7 and Economy 10 rates, they make it affordable for low-income households to keep their properties properly heated throughout the winter.

Furthermore, the storage heater upgrade also includes additional improvements such as loft insulation, an air-source or ground-source heat pump or a biomass boiler, and solar panels.

This is only possible thanks to the significant allocation this grant receives from the ECO4’s budget of £1 billion, bringing free funding to millions of families in the UK that need to upgrade their heating systems for the winter.

Eligibility Criteria for the Storage Heater Upgrade

Here you have the eligibility criteria and requirements of the storage heater upgrade, to help you see if you will qualify for this free grant.


The storage heater upgrade program is available in England, Scotland and Wales. Therefore, companies such as E. ON, nPower, EDF, British Gas, Scottish Power and SSE are helping low-income households to upgrade their storage heaters, as demanded by the ECO4 Scheme.

Property Ownership

The storage heater upgrade program is available for homeowners and private tenants. If you’re a homeowner, you can apply directly now, and if you’re a private tenant, you can also apply but we recommend talking about it with your landlord.

Because it’s a free upgrade, most homeowners will accept going through this process, especially since it will increase the value of the property, as modern heating systems are highly-demanded features in the real estate market nowadays.

Household Income

Because this program is aimed at low-income households, the household income must be lower than £31,000 per year, unless the following exceptions are met:

  • Someone in the household receives a qualifying income benefit;
  • Someone in the household suffers from a qualifying health condition

If it’s the case, then you might qualify for a free storage heater upgrade. Because these are conditions that make a household more likely to suffer from fuel poverty. Below, you will find the lists of qualifying income benefits and health conditions.

Income Benefits:

  • Income-based Job Seeker’s Allowance
  • Child Benefit
  • Income-related Employment Support Allowance
  • Pension Guaranteed Credit (Includes Savings Credit)
  • Universal Credit
  • Income Support
  • Working Tax Credit
  • Child Tax Credit

Health Conditions or Long-term Illness:

  • Diabetes
  • Respiratory diseases (for example, asthma)
  • Cardiovascular diseases (for example, coronary heart disease)
  • Immunosuppressive conditions
  • Limited mobility
  • Arthritis

Furthermore, it’s important to note that this health condition will have to be verified by one of the following professionals or entities:

  • An NHS Trust
  • A Local Health Board
  • An NHS Foundation Trust
  • A Health Board
  • Or a general medical practitioner.

Existing Storage Heaters and Heating System

To qualify for this government initiative, your existing storage heaters and heating system must meet the following conditions:

  • They are at least 5 years old
  • They have a low efficiency rate
  • They are faulty
  • They consume energy excessively (EPC D, E, F or G)

For example, if your home uses electric storage heaters with low heat retention, and they’ve been rated with an EPC F, then you might qualify for the storage heater upgrade grant.

EPC Rating

The EPC rating is one of the most important variables when evaluating your eligibility for the storage heater upgrade grant. According to the ECO4 Scheme, under which the storage heater upgrade operates, your property must be rated with an EPC D, E, F or G to be eligible.

Here you have the scale of EPC ratings along with their respective scores:

  • EPC A: 92+ points
  • EPC B: 81 to 91 points
  • EPC C: 69 to 80 points
  • EPC D: 55 to 68 points
  • EPC E: 39 to 54 points
  • EPC F: 21 to 38 points
  • EPC G: 1 to 20 points

A low EPC rate means that the property is likely to be consuming more energy than necessary, hence it’s a factor contributing towards fuel poverty.

Benefits of New Heaters from the Storage Heater Upgrade Scheme

Upgrading your storage heaters via the ECO4 scheme will bring you the following benefits that you’ll be able to enjoy from day number one after they’re installed in your property.

Keep Your Home Warm at a Low Cost

Traditional storage heaters offer low heat retention, and if they’re old, then they’re likely to consume plenty of electricity unnecessarily, hence bringing your home subpar heating at a much higher cost.

Thanks to this government initiative, you’ll be able to replace your existing old storage heaters with modern, high heat retention storage heaters that will keep your home warm at a low cost.

Furthermore, because this program can also include additional improvements such as a new energy-efficient boiler, insulation and solar panels, you can expect to save even more money while keeping your home warm and cosy.

Improved Home Comfort for Everyone

Not being able to keep your home warm during the winter is going to negatively affect the comfort of your home. And thanks to upgrading your storage heaters with more efficient and modern alternatives, you and everyone in your property will feel better. Because it’s going to stay warm during the winter at all times.

Because this initiative can also include the installation of systems such as air source and ground source heat pumps, it will also improve the comfort of your home during the summer, because these innovative solutions will keep your home fresh thanks to their capacity for producing conditioned air.

Bring Relief to Health Conditions

People who suffer from health conditions like asthma and arthritis will greatly benefit from living in a home that is properly heated throughout the day. Old and faulty storage heaters are not capable of doing it, especially if they lack a proper boiler or central heat system.

This is why it’s an excellent idea to apply for the free storage heater upgrade initiative, because it will help you to keep your home warm at all times, bringing relief to the persons in your property that suffer from health conditions or long-term illness.

Increase the Value of Your Property

This government-backed initiative will equip your home with brand-new storage heaters and other important upgrades such as a heat pump, new boiler, insulation and solar panels. This will make your home eco-friendly and more value in the real estate market.

Enhanced Safety For Your Family and Loved Ones

New storage heaters from the ECO4 Scheme are modern and require less maintenance, hence they will provide you and your family enhanced safety. You will be able to sleep well at night knowing that your home is safe while the storage heaters charge heat during off-peak electricity times.

Contribute to Helping the Planet and Combat Global Warming

The new storage heaters charge heat faster and retain heat at a superior rate than traditional storage heaters. Therefore, in addition to the additional improvements from the scheme such as insulation and solar panels, you will reduce your carbon footprint to help the planet.

What Other Improvements Does the Storage Heater Upgrade Program Offer?

Because the end goal of the ECO4 is to combat fuel poverty and reduce carbon emissions, the storage heater upgrade initiative also offers you additional upgrades and improvements for improving the energy efficiency of your property. You can find more info here on how the Free Boiler Scheme works.

Therefore, this program also puts at your disposal the following solutions for keeping your home warm during winter while spending up to 70% less energy:

  • Heat Pumps: The ECO4 Scheme offers two types of heat pumps, air source and ground source heat pumps. They are combustion-free, easy to maintain and can provide heat during the winter and keep the property fresh during the summer
  • New Boiler: It’s also possible to install a new biomass boiler under the ECO4 Scheme, when applying for the new storage heater upgrade grant
  • Insulation: Thanks to this initiative, you can also get funding to install loft and wall insulation in your property - this will allow your home to stay warm, and hence spend less energy on generating more heat
  • Solar Panels: Solar panels will provide your home with a source of clean energy that will reduce carbon emissions and help you save money on your utility bills. Therefore, the ECO4 Scheme makes it possible to equip your property with modern solar panels

The Real Running Costs of Free Heaters from the ECO4 Scheme

Let’s unveil the real running costs of the upgraded storage heaters you can get via the ECO4 scheme, to help you decide if it’s the right choice for your own case. To better understand it, we need to divide it in three sections: heat charging, running and seasonal costs.

Heat Charging Costs

In order to store heat, the storage heater will have to charge heat, and this process will demand approximately 1kW. However, this only applies to modern storage heaters from the storage heater upgrade scheme, because old and faulty storage heaters can consume up to 3kW, which is 200% higher.

It’s also worth noting that the new storage heaters from the ECO4 Scheme will stop using energy after they have stored enough heat, hence they will prevent wasting energy.

Running Costs

To figure out the running costs of an average new storage heater from the ECO4 Scheme, let’s suppose it consumes 2kW and that it operates at top capacity for seven off-peak hours. This would result in a total of 14 kilowatt-hours, which according to the actual off-peak electricity rate in 2024 of 16.00p/kWh, would cost you £2.24 per day.

Seasonal Costs

You might not need to use the storage heaters during summer at all, and hence this will drive down how much you spend on heating throughout the year. Therefore, the average running costs can go below the £2.00 mark.

About the Off-Peak Tariff and the Storage Heater Upgrade

Another important factor when it comes to the storage heater upgrades and the available units under this scheme is the off-peak tariff. Here you will find all the information about it.

What Are Off-Peak Electricity Times?

Off-peak electricity times are when power is at its lowest demand, hence ECO4 energy providers offer off-peak tariffs known as Economy 7 and Economy 10 that charge less for electricity during the night and small hours of the morning.

Why Do They Matter for the Storage Heater Upgrade?

They matter because modern storage heaters from the ECO4 Scheme will only charge heat and consume electricity during off-peak electricity times. Evidently, this will help you to save plenty of money on heating costs while reducing carbon emissions.
