The Energy Company Obligation (ECO) is a significant government-funded programme in the United Kingdom. It aims to enhance the energy efficiency of residential buildings and improve the living conditions of their occupants.

Currently, it’s the fourth phase of this initiative, ECO4. It started in August 2022 and will continue until March 2026. So, what’s the ECO4 scheme? Like all the previous iterations, ECO4 is all about making homes better for the environment and the people living in them.

In this article, we’ll discuss everything about ECO4, from what it aims to achieve to its benefits and the types of improvement it covers. By the end, you should have a comprehensive understanding of how ECO4 is making a positive impact in the UK.

About ECO4 Scheme

The ECO4 is the fourth and final phase of the UK government initiative that started back in 2013. The main goal of this programme is to support low-income households and give people more energy-efficient homes to live in. Raising the UK’s housing stock to minimum energy efficiency requirements should help in ensuring the comfort of UK families whilst also reducing their energy bill burdens.

Such a programme qualifies households to receive funding for installing energy-efficiency-promoting improvements. Since it first began, the ECO scheme has helped transform hundreds of thousands of homes. This final phase aims to go above and beyond, and besides helping vulnerable people upgrade their homes and heating systems, this initiative is also part of the steps towards the UK’s net zero goal by 2050.

Essentially it aims to create a more energy efficient home for those in the UK who are struggling with high energy costs. The most energy inefficient properties in the UK need government attention in order to ensure that their legally binding target of reaching net zero carbon emissions by 2050 is met.

Key Objectives Of ECO4

The ECO4 scheme has wide-ranging benefits for both the environment and the well-being of the people, driven by several key objectives, including:

  • Lowering Carbon Emissions: One of the primary goals of ECO4 is to promote energy-efficient practices and technologies. As a result, it helps lower carbon emissions and contributes to the nation’s efforts to combat climate change. Making energy efficient upgrades to reduce carbon emissions is one of the scheme’s main aims.
  • Improving Energy Efficiency: ECO4 also seeks to make homes more comfortable and cost-effective for residents by improving their energy efficiency. This includes upgrading insulation, heating systems, and other elements to decrease energy consumption.
  • Alleviating Fuel Poverty: The scheme addresses fuel poverty too. Through energy-saving improvements, it helps vulnerable households reduce their energy bills. Plus, it plays a critical role in ensuring fair access to efficient and affordable energy.


What Improvements Does ECO4 Cover?

ECO4 is a programme that includes various energy efficiency upgrades to transform homes into more sustainable and environmentally friendly spaces. Such actions are specifically designed to address energy-related issues within the household, and they include:

Insulation Upgrades

Insulation upgrades are the main focus of the ECO4 scheme. Such enhancements are estimated to help households save money.

Depending on the specific needs of each household, many insulation measures are available through this initiative. This includes cavity wall insulation, solid wall insulation, room-in-a-roof, and loft insulations.

Moreover, the scheme adopts a fabric-first approach. Mainly, it means prioritising the improvements of the property’s energy efficiency through insulation before considering other measures, such as heating system upgrades.

Where cavity wall insulation measures are appropriate, this will usually be considered first as it’s often a cheaper, quicker fix for energy efficiency installers.

Heating System Installations

The ECO4 scheme also supports the installation of environmentally friendly heating systems. This includes air-source heat pumps and biomass boilers. An air source heat pump, funded through an ECO4 grant, is significantly cheaper than it would otherwise be.

Such advanced heating systems as an air source heat pump can replace outdated and inefficient boilers effectively. Consequently, it leads to a potential energy bill reduction for households. If such heating systems aren’t suitable alternatives, the ECO4 scheme still has an option for solar panel installations where necessary.

In some cases ECO4 may allow for an energy-efficient electric storage heater or electric storage heaters to be installed at your property if it is the most effective way of warming your home for less. But these are usually rare and are only appropriate for properties which cannot support central heating systems.

Boiler Repairs

Fortunately, not all boilers need replacing with green heat systems. In fact, the ECO4 scheme also provides funding for repairing and upgrading existing boilers to improve their efficiency. Such practices aim to maximise the lifespan of boilers to last for over ten years and to ensure high rated boilers can continue operating for longer.

That said, the aspects covered by the ECO4 scheme under the “boiler repair” solution are diagnostics, cleaning, and repair. Boiler replacements for the least energy efficient homes aren’t possible, so other measures would need to be considered here.

Individuals Eligible For ECO4 Scheme

The eligibility criteria for the ECO4 scheme can make energy efficiency improvements available for a wide range of individuals and households. If you receive qualifying benefits and are a homeowner or a private tenant, you may benefit from this program.

Am I Eligible?

To confirm your eligibility, you should undergo a check by the Department for Work and Pension (DWP). Such a check verifies your benefit status, but you might need to make a self-declaration regarding your household income, which must fall within the specified thresholds to be eligible.

I’m A Landlord – Will My Tenant Qualify?

As for landlords with tenants who receive benefits, it’s vital to encourage them to apply for the grant. Not only does this help create a cost-effective living environment for your tenants, but it also enhances the energy efficiency of your property.

LA Flex Program

There’s still a chance to qualify for the ECO4 scheme with LA Flex, a related set of rules that helps households that don’t claim benefits access funding. This works through the flexible eligibility program endorsed by certain councils.

Luckily, such a program provides the chance to upgrade homes. That’s especially true for those with the lowest energy efficiency (Energy Performance Certificate rating of D or lower). As a result, it ensures everyone gets the opportunity to benefit from reduced energy bills.

Check with your local council to see if you qualify for support under LA Flex rather than ECO4.

Energy Performance Certificate Requirements

The Energy Performance Certificate (EPC) is a document that provides information about the energy efficiency of a property or a building. It helps property owners understand the energy performance of their buildings.

Primarily, this rating can be used as a signal to ECO4 inspectors that energy efficiency measures could be required at a property.

To benefit from the ECO4 scheme, the EPC rating of a building must indicate that it requires improvement. Generally, properties with an EPC rating of D or lower may be eligible for energy upgrades.

So, if a property has an existing EPC rating of D or E, the program needs to improve that rating to at least a C. On the other hand, if the current EPC rate is F or G, the program should improve it to reach a rating of at least a D.
