About Warmworth

Last reviewed 19 May 2026

Warmworth is an independent guide to UK home energy grants. We're built around one promise: the recommendations on this site never change based on who pays us most.

Why we exist

In May 2026 the UK home energy landscape is more complex than it has ever been. The Warm Homes Plan launched in April with £13.2 billion in capital funding. The Boiler Upgrade Scheme is rising to £9,000 in July. Air-to-air heat pumps now qualify for a £2,500 grant. ECO4 ended in some forms and was extended in others. GBIS closed without a successor. The EV charger grant doubled — but only for renters and flat owners. Smart Export Guarantee rates fell at the same time as supplier-tied bundles became more lucrative.

For an English homeowner trying to work out what they qualify for, the answer is genuinely hard. The official sources are spread across dozens of gov.uk pages, devolved-government microsites and Ofgem PDFs. The popular sites are mostly run by people who want to sell you something — installers, comparison aggregators, lead-gen marketplaces. There is, as of mid-2026, no major independent guide that maps the whole landscape, covers all four UK nations equally, and updates monthly.

That's the gap we built Warmworth to fill.

What we promise

1. We don't install anything

We are not solar installers. We are not heat pump installers. We don't broker insulation contracts. Where we tell you a scheme is the right answer, we'll point you to the official gov.uk page first. If you then want an installer quote, we may signpost you to vetted MCS-certified networks — but only after you've seen the official route.

2. We are transparent about how we earn

We earn money in three ways, in this order of priority:

1. Display advertising — programmatic ads served on the site. These have no influence on editorial content.
2. Affiliate referrals to vetted installers — only after we've shown you the direct gov.uk route. If you choose to get installer quotes through us, we may receive a referral fee from MCS-certified, TrustMark-registered installers. The fee is the same regardless of which installer you pick, so our recommendation is not influenced by who pays most.
3. Affiliate referrals to energy suppliers for switching (e.g. Octopus Refer, Look After My Bills). Same model — fees don't influence the supplier recommendations.

We do not sell leads. We do not share your email or phone with anyone you haven't explicitly opted in to be contacted by.

3. We update monthly

Home-energy policy in the UK moved more in the first six months of 2026 than in the prior three years. Every cornerstone page on Warmworth carries a visible "Last reviewed" date stamp and a changelog showing what was updated when. The rules engine that powers our eligibility quiz is versioned — current version 1.2.0 as of 18 May 2026. You can read the full methodology and changelog.

4. We cover all four UK nations

England, Scotland, Wales and Northern Ireland all have different schemes, eligibility rules and amounts. Every grant page on Warmworth has equal-weight coverage for all four — not England-first with the devolved nations as a footnote. Scotland in particular has the most generous standing offer in the UK (Home Energy Scotland Grant & Loan combines £7,500 + £7,500), and Northern Ireland has almost no national coverage anywhere else online.

5. We tell you when not to apply

Three places in our content we say "wait, don't apply":

• If you have an oil or LPG boiler — wait until July 2026 for the BUS £9,000 uplift, not £7,500.
• If your insulation is poor — insulate first, heat pump second. Skipping that order routinely costs households £400–£800 per year.
• If you don't have a smart tariff yet — a battery without one earns essentially nothing.

Saying "wait" loses us a sale today. But it's the right answer, and over time it's how trust is built.

What we are not

• We are not affiliated with HM Government, Ofgem, DESNZ, Energy Saving Trust, or any devolved administration. We cite their guidance because it's authoritative — not because we represent them.
• We are not a price-comparison switching site like Uswitch or MoneySupermarket. We don't take commission per switch (with the exception of energy supplier referrals, disclosed above).
• We are not a lead-generation marketplace. If you don't want installer quotes, you don't have to give us any contact details — the quiz, the calculators and the content all work for an anonymous visitor.

How to contact us

The fastest way to reach us is by email: hello@warmworth.co.uk. If you've spotted a factual error, an out-of-date amount, or a scheme we should be covering, please tell us — we'd rather hear from you than have a reader rely on the wrong number.

For corrections and complaints we aim to respond within two working days. Verified corrections appear on the relevant page's changelog with the date of the change and (where possible) credit to the reporter.

Editorial team

Warmworth is built and maintained by a small editorial team. Author bylines appear on every grant deep-dive page from June 2026 onwards. Until then, all content is published under the editorial team's collective oversight, with sources cited on every factual claim.
