Run checkerEvery UK Local Authority has its own Flex scheme parameters. We publish 360 LA-specific landing pages with the current Statement of Intent and route-specific eligibility criteria.
Indicative figures based on Ofgem ECO4 quarterly reports. Actual LA spend varies by stock characteristics + local fund allocation.
We don't sell grants or installers. We don't take referral fees from grant administrators. We exist to help households find the route that actually applies to them, not the one that pays us best.
The UK grant landscape changes rapidly — ECO4 ends March 2026, GBIS Plus is being designed, BUS replacements are being scoped. We update this site quarterly to reflect the actual current state.
One of the most-missed grant routes is LA Flexible Eligibility, because every council writes their own scheme. Our 360 LA pages publish each Statement of Intent and the specific qualifying criteria.
The eligibility checker doesn't require email or phone. The result is shown to you on screen. If you choose to download a PDF report or get connected to an installer, that's opt-in.
The grant-eligibility-and-routing work on this site sits inside a broader Eco Saving Hub consumer-grant network that covers every active retrofit-funding pathway in the UK alongside the calculator surfaces that model the funded-package size for any given household. The hub is the canonical consumer-facing reference for the major schemes (ECO4, GBIS, Boiler Upgrade Scheme, LA Flex pathways, Disabled Facilities Grant routes) and is open about the scheme logic, eligibility thresholds, and qualifying flags that drive the household-level outcome. Most households who think they qualify for one scheme actually qualify for a different one, and the hub routing surfaces are designed to surface the correct pathway in under three minutes rather than the historic call-and-callback cycle through an installer or local-authority commissioning team. The two sites are designed to work together: read this site for the eligibility-checker output, read the hub for the broader scheme-by-scheme picture and the calculators that model the funded package against the household specific circumstances.
