Independent Energy Guide · Free to Use

Helping UK homeowners find available support

We cut through the complexity of UK energy grants — ECO4, insulation, solar, heat pumps and boiler replacement — and help you understand which support routes may fit your home. Free to use, independent, and not a government website.

Eligibility checks are indicative only. Final approval depends on scheme rules, property surveys, funding availability and installer/supplier checks.

What we do

The UK government runs billions of pounds worth of energy grant schemes every year — ECO4, the Great British Insulation Scheme, the Boiler Upgrade Scheme, Warm Home Discount and more. The problem? The official guidance is dense, the eligibility rules shift constantly, and most people have no idea what they qualify for.

We make that easier. Enter your postcode, answer a few questions, and we'll show the schemes that may fit your situation — then connect you with vetted local installers who can confirm eligibility, survey the property and explain any costs before work begins.

Why we built this

Here's an uncomfortable truth: millions of UK homeowners are sitting on grants they've never claimed. Fully funded boilers or insulation, subsidised solar, and heat pump funding can be available in the right circumstances — but each scheme has strict rules and budgets.

But the process to access it? Fragmented across council websites, confusing government portals, and installer sales teams who don't always have your best interests at heart. We've seen people miss support they may have qualified for. We've also seen legitimate applications fall apart because of one missed form or an avoidable eligibility issue.

So we built one place where you can cut through all of that. Check every grant, compare every option, understand what support may be available — without being sold to, confused, or overcharged.

How we make money

Transparency matters. Here's exactly how we fund this:

Our revenue never influences our recommendations. If a grant isn't right for you, we'll say so. If a quote looks high, we'll flag it. We're only useful if you trust us — so we keep it straight.

📋 A note on our name

There is also a government-owned organisation called Great British Energy, established under the Great British Energy Act 2026 to invest in UK renewable infrastructure — wind farms, solar projects, and national grid development. They do important work at a national level and operate at gbe.gov.uk.

We are a separate, independent website. We are not affiliated with them, and they are not affiliated with us. Our focus is entirely different — we help individual homeowners understand and access the energy grants and savings available to them right now.
