Energy companies offer ECO4 energy saving grant funding for those eligible. Improvements may include air-source heat pumps and biomass boilers, as well as thermal insulation upgrades.

Since 2013, the government’s ECO Scheme has been running in its current iteration, ECO4. There have been some modifications that affect who can apply for grants under this phase.

To qualify for an ECO 4 energy saving grant, first understand your home’s current Energy Performance Certificate rating, which can be found by searching the Energy Performance Certificate Register. After this step has been taken, determine which measures would be most suited to meet your specific needs and put them into action accordingly.

ECO4 is the fourth phase of the Energy Company Obligation and will run until 2026. It differs from ECO3 by taking a more comprehensive approach to improving energy efficiency within homes through measures such as external wall insulation. Furthermore, Local Authority Flexible Energy (LA Flex) gives greater flexibility as to who can apply.

Landlords and private tenants who meet certain criteria, such as claiming benefits and meeting income requirements, can qualify for the ECO 4 scheme. Our eligibility checker makes it quick and easy to determine your eligibility.


ECO4 is part of the Energy Company Obligation initiative launched by the British government in 2013. This scheme mandates that energy suppliers fund energy efficiency measures like insulation to help homeowners save money on their energy bills. Homeowners can take advantage of it without incurring additional charges and enjoy free savings through this scheme.

This scheme seeks to improve low-income and vulnerable households’ least efficient homes by first improving the fabric of their property before installing new heating systems, then offering energy-saving measures like insulation or solar panels.

ECO4 is an energy efficiency initiative launched by the British government to enhance home energy ratings and cut carbon emissions across Great Britain. Starting in April 2022 and running until March 2026, its aim is to help people keep their homes warmer while cutting energy costs. The government has set a national annual bill savings goal, giving people hope of keeping warm homes while saving energy costs.


ECO 4 is the fourth phase of the Energy Company Obligation scheme and was implemented to address carbon emissions, and fuel poverty, and meet net-zero commitments by providing funding for measures including cavity wall insulation, gas boiler replacement or upgrade, heating control upgrades, loft or room-in-the-roof insulation, as well as renewable energy solutions such as solar panels.

The ECO4 scheme will focus on energy-inefficient homes. This will include those living in fuel poverty, vulnerable households, and having an EPC rating of Band D. Additionally, those who reside in properties without energy efficiency measures and those residing in social housing will all be prioritised for improvement.

The ECO4 scheme features different eligibility requirements than its predecessor, ECO3. This includes changes to which benefits qualify and an increase in allocations for people who don’t claim any. Furthermore, this scheme takes an innovative fabric-first approach to increasing home energy efficiency.


ECO4 is the fourth phase of the Energy Company Obligation scheme run by the government and will run from April 2022 until March 2026, being open only to households receiving certain benefits. It aims to enhance the energy efficiency of low-income homes occupied by low-income, vulnerable families to help meet its targets for fuel poverty and carbon reduction.

ECO4 will cover an array of home improvements, such as insulation and boiler replacements, energy-saving measures like solid wall and cavity wall insulation, and providing free upgrades—typically gas-fired condensing boilers with radiators—for people without central heating in their properties.

To qualify for a free ECO4 grant, first, visit an installer and complete a home assessment. They will ask a series of questions regarding your income and benefits status, as well as the energy rating of your home.
