Who qualifies for ECO4 funding?

Homeowners and private tenants on qualifying benefits including Universal Credit, Pension Credit, Child Tax Credit, ESA, JSA, and Housing Benefit. Properties must generally have an EPC of D or below. Some households qualify through the LA Flex pathway based on income (typically below £31,000) and health conditions.

Is ECO4 funding genuinely free?

Yes. ECO4 is funded by energy suppliers as a legal obligation. There is no cost to eligible households — no hidden fees, no loans, and no repayment required. OMEGA manages the entire process directly with the obligated suppliers.

What insulation can I get through ECO4?

ECO4 covers loft insulation, cavity wall insulation, external wall insulation, underfloor insulation, and in some cases room-in-roof insulation. In many properties, heating system upgrades can also be funded. Our surveyor will recommend the most effective combination of measures for your home.

How long does the ECO4 process take?

From initial survey to completed installation typically takes 2–4 weeks, depending on the measures being installed and survey findings. Loft insulation can often be installed within days of approval, while external wall insulation may take longer to schedule and complete.

Will ECO4 funding continue in 2025 and 2026?

ECO4 is currently scheduled to run until March 2026. Funding allocations are limited and demand is high, so we recommend applying as soon as possible to secure support while the scheme is still open.

ECO4 · Grants & funding

ECO4. What it actually covers, and who qualifies.

ECO4 is the largest grant scheme available to UK homeowners for insulation and heating upgrades. It is funded by the major energy suppliers — not paid out as cash, but applied as a discount against the install cost. Most qualifying households pay nothing or close to it. Subject to eligibility — we check the live position on every survey.

What Does ECO4 Cover?

ECO4 takes a whole-house approach, funding the measures that will make the biggest difference to your home's energy performance. This typically includes loft insulation, cavity wall insulation, external wall insulation, underfloor insulation, room-in-roof insulation where applicable, and heating system upgrades.

The scheme aims to bring properties up to at least an EPC Band C, which can reduce energy bills by an estimated £300–£900 per year depending on your property type and current insulation levels.
