Energy Guides and Comparisons

Every guide here answers a specific question we get asked constantly: how much do solar panels actually cost, which heat pump brand is worth the money, what does your EPC rating mean for grant eligibility. No filler. Costs, grants and practical next steps, checked against current government and industry data for April 2026.

Common questions

About these guides

Are these guides free to read?
Completely free. Some guides contain affiliate links to installer quote services, and we flag those clearly at the top of the article. You're never charged for reading anything on Eco Home Check.
How often are the guides updated?
Comparison guides get a full review every quarter. Informational guides are reviewed annually or sooner if a scheme changes, a grant amount shifts, or costs move enough to matter. Every guide shows a 'Last reviewed' date so you can judge for yourself.
Who writes the guides?
Our content is researched and produced by the Eco Home Check editorial team — writers, researchers and fact-checkers with backgrounds in UK energy policy, consumer affairs and personal finance. Every article is verified against primary government sources (GOV.UK, Ofgem, MCS Register) before publication. Read more about our editorial process on our methodology and editorial-policy pages.
