The Energy Company Obligation (ECO) Scheme 2024

Energy Company Obligation ECO Scheme

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 ECO Schemeindependent 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 Energy Company Obligation

  • 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.

Are you eligible for the Energy Company Obligation?

It is recommended that you compare what each supplier offers so that you can find the best measures that will benefit your home and circumstances. Be aware though, that there are strict criteria you must meet in order to be eligible.

How to apply for the ECO scheme?

If you think you qualify for ECO support, the first thing to do is research the leading suppliers and find out what each of them are offering. Once you have found one you're interested in, you can contact them or apply directly via most of the supplier's websites.

Things to remember:

  • Although most available offerings are free, you may still be charged for some elements of an installation, so be sure to check this with the supplier before you proceed.
  • Each supplier may offer something different, so it's worth checking around to get the most suitable benefit for your home.
  • Not everyone is eligible, be sure to check the full criteria before you contact a supplier.
  • You don't need to be a customer to use any of the ECO suppliers.

If you're unsure about the criteria, or would like to find out more information, you can visit the Ofgem website or contact your local authority for further assistance.

The government also provides a helpful grants checker to quickly see if you are eligible for any other home heating support. You can also find out more about all available energy grants here, Grants and Schemes.


The latest version of the scheme is known as ECO4, and it will run from April 2022 – March 2026. Some legislation is still being finalised, but full details of any amendments are available from Ofgem.

You can also get free support in applying for the ECO at www.boilergrants.co.uk (please note this site is currently being updated).


How does the Energy Company Obligation work?
The Energy Company Obligation is a government initiative which means the major energy suppliers in the UK are obligated to provide efficiency measures to British homes. These are free, or low cost upgrades. The aim is to improve home efficiency and reduce consumers’ energy bills. Find out more about what the ECO is.

Who qualifies for an ECO grant?
The ECO is for those on low income or receiving certain benefits. Take a look at the qualifying criteria to see if you are eligible.

When did the Energy Company Obligation start?
The scheme started in April 2013, but the current version, ECO4 runs from April 2022 – March 2026. Find out more about why the scheme began.

Is the ECO scheme free?
Some of the upgrades available via the ECO scheme may be offered for free, or for a cut-price. The price you pay will depend on the type of installation and the supplier. We recommend talking to multiple suppliers to determine what is available and how much it may cost. Find out more about ECO suppliers.

Who pays for ECO?
The scheme was created by the government and is led by major energy suppliers, who each choose which upgrades they will offer. Whilst some of the upgrade is covered by the supplier (through consumer bills), a portion of the costs may be passed onto the homeowner receiving the upgrade. This will differ between supplier and the type of upgrade. Find out how you could benefit.
