The ECO4 scheme is a government-backed programme, funded by energy suppliers, that gives eligible UK households free boilers, heat pumps with solar panels, and insulation. You may qualify if you own your home or rent privately, have an EPC rating of D to G and receive a qualifying benefit, or meet your council’s LA Flex criteria. ECO4 closes on 31 December 2026, so apply now.
Not eligible? The Boiler Upgrade Scheme and our solar panel installations are open to all homeowners.
Replace your old boiler with an efficient A-rated model for free. As a result, you enjoy a warmer home and lower energy bills.
Upgrade to an air source heat pump, often with free solar panels. In addition, you cut your carbon emissions.
Solar panels and battery storage with £0 upfront finance, so you generate your own power and cut your bills.
Get £7,500 towards a heat pump, or up to £9,000 for oil and LPG homes, with no income test.
ECO4 can cover a new boiler, loft and cavity wall insulation, radiators, smart heating controls, and renewable heating such as air source heat pumps with solar panels. In addition, installation is free.
ECO4 stands for Energy Company Obligation (fourth phase). It is a UK government scheme that requires large energy suppliers to fund heating and insulation upgrades for low-income and vulnerable households. In fact, this phase began in April 2022 and has been extended to 31 December 2026. Furthermore, it is regulated by Ofgem and covers England, Scotland and Wales.
ECO4 is worth around £1 billion a year and focuses on the least energy-efficient homes. As a result, it helps to cut energy bills, raise EPC ratings and reduce fuel poverty. It covers boiler replacement, air source heat pumps, solar panels, smart controls and first-time central heating for homes with no existing system.
Many UK households trust ECO4 because it reduces fuel poverty and supports renewable energy. Households on certain government benefits can get 100% of the cost of a heating upgrade covered, often with free insulation. Moreover, the success of the earlier ECO1, ECO2 and ECO3 phases has built strong public trust in the scheme.
ECO4 closes on 31 December 2026. After that, help with home energy upgrades continues through the government’s Warm Homes Plan, the Boiler Upgrade Scheme and finance-backed installations. ECO Energy Packs will keep helping you find the right route for your home, so apply for ECO4 now while funding lasts and plan your next upgrade with us.

ECO4 (Energy Company Obligation 4) is a UK government scheme that requires large energy suppliers to fund heating and insulation upgrades for low-income and vulnerable households. Eligible homes can get a free boiler, heat pump, insulation or central heating.
You may be eligible if you own your home or rent privately, your home has an EPC rating of D to G, and someone in the household receives a qualifying benefit such as Universal Credit or Pension Credit. Otherwise, you may qualify through LA Flex.
ECO4 has been extended and now closes on 31 December 2026. However, supplier funding is limited and can run out earlier, so it is best to apply as soon as possible.
ECO4 can fund boiler replacements, air source heat pumps, solar panels, loft and cavity wall insulation, electric storage heaters, smart heating controls and first-time central heating, including installation.
Yes, for eligible households. Energy suppliers fund the upgrades, so there is nothing to repay and no hidden charges for the survey, application or installation.
After December 2026, support continues through the Warm Homes Plan, including council-led Warm Homes Local Grants for low-income homes. In addition, the Boiler Upgrade Scheme offers £7,500 towards a heat pump in England and Wales, or up to £9,000 for oil and LPG homes until March 2027.
Yes, possibly. Through LA Flex, your local council can refer you if your household income is under about £31,000 or someone in the home has a health condition made worse by the cold.
Most boiler installations take one day, and insulation usually takes one to two days. Heat pump installations typically take two to five days, depending on the work needed.
Yes. ECO4 covers England, Scotland and Wales. It is not available in Northern Ireland, which has its own schemes.
ECO4 closes on 31 December 2026 and supplier funding can run out earlier. Check your eligibility now to secure free heating and insulation upgrades for your home.
Great service from Eco Energy Pack! I installed a free A-rated boiler through the ECO4 grant scheme, and the whole process was so easy. The team handled everything, from paperwork to installation, and they left my house immaculate. I have already seen how warm my house feels! Thank you!

Had my loft insulation installed with the ECO Energy Pack, and I can already feel the difference. The house now keeps so much heat. Installers were professional, humble, and sure to clean up later. Great experience to end!

I was struggling with a high heating bill and an old boiler that worked hard. Eco Energy Pack helped me apply for a government grant, and within weeks, I had a new energy-efficient boiler installed for free! It was so easy, thank you!

Eco Energy Pack fitted us with an air source heat pump and solar panels, and it has been a game-changer. The house remains hot without using more electricity, and our bills are very low. The team was kind and professional and they even explained to us the whole working process of a heat pump. Highly recommended!!
