The Energy Company Obligation (ECO) Scheme 2024
Did you know that you could be entitled to free energy upgrades to your home? Since 2013, major energy companies in the UK have had a legal obligation to provide free improvements to homes across the country, this includes new boilers and home insulation.
If you're interested in a new energy-efficient boiler, you could be entitled to an upgrade. Find out if you could benefit and how to apply below (you can also check out learn more about whether you qualify for ECO and similar grants here).
What is the Energy Company Obligation (ECO)?
To tackle fuel poverty and reduce carbon emissions, the government created the Energy Company Obligation, which is set to run until 2028.
The obligation means that major energy suppliers in the UK must provide a certain level of free support to consumers. This support can be in the form of home improvements, such as loft insulation, or the installation of high efficiency boilers. These improvements have multiple benefits, not only for the environment but also for the consumer, as they can lead to lower energy bills.
How does the ECO scheme work?
The ECO is a scheme which ensures that medium to large energy suppliers in the UK give back to those consumers who are most in need, such as those on low incomes or receiving benefits. It's also a way of holding major companies accountable for improving their environmental impact.
Ofgem (The Office of Gas and Electricity Markets), are an 
independent administrator for the scheme and they have been developing the ECO since its launch. Through public and government consultations, they are frequently improving the scheme, which is currently in its fourth version (ECO4).
Ofgem sets targets for energy suppliers and monitors their progress. Each supplier is set its own goals based on how many customers, and what percentage of the market they hold. For example, the bigger, more major suppliers, will need to deliver more upgrades.
You can find out more about how the ECO works and how targets are set on the Ofgem website.
How can you benefit from the ECO scheme?
The main upgrades which suppliers will offer include loft and cavity wall insulation and boiler upgrades. Depending on the level of work needed, and which supplier you use, you may be required to contribute to the cost of the upgrade, but this is dependent on your circumstances.
Below are some examples of current ECO upgrade offers:
- Insulation
(Cavity wall, loft, underfloor, solid wall) - New boiler
- New storage heaters
- Central heating
Insulating your home can make a drastic improvement to your energy bills. If you live in an older home, built before the 1990s, it's likely that your home is not insulated effectively. Most older homes will have cavity walls, allowing over a third of your home’s heat to be lost.
Similarly, around a quarter of your heating will escape through the roof if it is not insulated. With all that heat escaping, you will be spending more on energy to try and keep your home warm. Not to mention the increase in carbon emissions with the more fuel you burn.
You could also benefit from a boiler replacement, which will dramatically reduce emissions and your bills. If you have a boiler that frequently breaks down, or is over 10-15 years old, it will no longer be working efficiently for you. It's also not going to be of the same quality as a new, modern boiler, which is made to be as efficient as possible.
Although you won't be able to choose exactly what a supplier may offer you, for example, which boiler model you get, it's clear from the obligation guidelines that whatever you are eligible for is going to greatly benefit your home.
Which suppliers offer ECO upgrades?
The good news is, you don't need to be a customer with any of the suppliers who are obligated to the scheme. Which means that if you fit the criteria, you can choose which supplier you benefit from. As each supplier may provide something different, this gives you a bit more flexibility in what you may be able to receive.
Below are some of the suppliers who provide ECO support:
- British Gas
- Bulb
- EDF Energy
- E.On Next
- Octopus Energy
- OVO Energy
- So Energy
- Utilita
Please note that this list may change, so it's worth doing research if/when you want to use the scheme. Ofgem also has a supplier list on their website.
