The UK Government has officially launched the ECO5 energy efficiency scheme today, succeeding ECO4 with broader eligibility and up to £10,000 in free upgrades for low-income households. New rules prioritise solid wall insulation and low-carbon heating amid rising fuel poverty. Homeowners urged to check eligibility before the first application window closes in June 2026.
In a major boost for households grappling with high energy bills, the Department for Energy Security and Net Zero (DESNZ) has launched the Energy Company Obligation 5 (ECO5) scheme on 25 March 2026, just weeks after ECO4's closure. Running until March 2028, ECO5 mandates energy suppliers to deliver £4 billion in home upgrades, targeting 700,000 properties to cut emissions and fuel poverty. Eligibility has been widened to include households with incomes under £32,000 receiving benefits like Universal Credit or Pension Credit, with new emphasis on heat pump installations and solid wall insulation. According to DESNZ figures, this could save qualifying homes up to £450 annually on heating bills. Experts at freeboilerupgrade.uk, contactable on +447375868046, predict a surge in applications as spring assessments ramp up.
Key Changes from ECO4 to ECO5
ECO5 builds on its predecessor's success, where ECO4 delivered over 1.2 million measures since 2022, including 150,000 boiler replacements and 500,000 insulation projects (DESNZ data, 2026). The new scheme introduces a £10,000 cap per household for combined upgrades, up from £7,500 under ECO4, specifically targeting EPC band D-G homes. Solid wall insulation, previously underutilised, now receives priority funding with grants covering 100% of costs for eligible properties.
A significant shift is the integration of low-carbon heating: heat pumps qualify for up to £8,000 alongside the Boiler Upgrade Scheme's £7,500 grant, potentially stacking for fuller coverage. Suppliers like British Gas and E.ON must meet stricter delivery quotas, with 40% of measures now mandated for solid wall and cavity wall insulation in deprived areas. Ofgem will oversee compliance, publishing quarterly progress reports starting June 2026.
Eligibility and Application Process
To qualify for ECO5, households must have an Energy Performance Certificate (EPC) rating of D or below, receive qualifying benefits such as Universal Credit, Pension Credit, Child Tax Credit (income under £32,000), or Housing Benefit, and reside in England, Scotland or Wales. Private renters need landlord consent, while social housing is automatically prioritised via Local Authority Flex (LA Flex) expansions.
Applications open immediately via energy suppliers or approved installers. Freeboilerupgrade.uk offers a quick eligibility checker, with experts available on +447375868046 to guide homeowners through surveys. DESNZ estimates processing times of 4-6 weeks, with installations targeted for completion by autumn 2026 to beat winter demand. Unlike ECO4, ECO5 includes a 'fast-track' for fuel-poor households identified via Warm Home Discount lists.
Impact on Fuel Poverty and Emissions
With 3.2 million UK households in fuel poverty as of March 2026 (End Fuel Poverty Coalition), ECO5 aims to lift 200,000 out through average savings of £420 per year on gas and electricity bills. Government modelling from GOV.UK projects a 15% reduction in carbon emissions from treated homes, aligning with the 2030 clean heat targets.
Regional disparities are addressed: LA Flex funding rises to £500 million, enabling councils in the North West and Scotland to deliver 100,000 measures. Early data from pilot areas shows heat pump installations under ECO5 achieving 40% efficiency gains over gas boilers, per Ofgem trials.
What This Means for Homeowners
Act now: With supplier quotas filling fast, March and April 2026 offer the best window for assessments. Contact freeboilerupgrade.uk or call +447375868046 for impartial advice on stacking ECO5 with the Great British Insulation Scheme or Boiler Upgrade Scheme. Expect full upgrades—new boilers, insulation, and smart thermostats—at no upfront cost.
Long-term, EPC improvements to band C could boost property values by 5-10% (Zoopla 2026 report) and protect against future regulations like the 2028 gas boiler phase-down. Non-qualifiers should explore the £150 Warm Home Discount, automatic for 2 million prepayment meter users this winter.
