Helping UK homeowners claim what they're owed

We cut through the complexity of UK energy grants — ECO4, insulation, solar, heat pumps, boiler replacement — and connect you with the savings you're entitled to. Free, independent, always on your side.

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 fix that. Enter your postcode, answer a few questions, and we'll tell you exactly which schemes you're eligible for — and connect you with vetted local installers who can carry out the work, often for free.

Why we built this

Here's an uncomfortable truth: millions of UK homeowners are sitting on grants they've never claimed. Free boilers. Free insulation. Subsidised solar. Heat pump funding. It's all there — budgeted, allocated, waiting.

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 pay thousands for upgrades that should have been free. We've seen legitimate applications fall apart because of one missed form.

So we built one place where you can cut through all of that. Check every grant, compare every option, understand exactly what you're entitled to — 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.
