What Energy Stack is, and what it isn't
An independent UK reference for the home energy stack: solar, batteries, EV charging and heat pumps.
The home energy market in the UK has become genuinely complex. Solar, batteries, EV chargers and heat pumps all interact, and the installer-side material tends to be either thin SEO content or thinly-veiled lead generation. Energy Stack covers the practical bits properly: what to expect from each install, what questions to ask before signing a quote, and rough numbers for how each piece of kit pays back.
What's here
Reference content on the four pillars of a modern home energy setup: solar generation, battery storage, EV charging and heat pumps. Each topic has a knowledge base of structured reference pages, calculators for the obvious money questions, and longer articles on the bigger decisions. A separate reference section covers cross-cutting topics like single-phase vs three-phase supply, DNO notifications and MCS certification, which span multiple topics.
How the content is made
Articles and reference pages are researched and written from public sources: regulator publications, manufacturer datasheets, UK statistics (DESNZ, MCS, Ofgem), and reasoned analysis. Where a calculator depends on assumptions, those assumptions are visible underneath the result, not hidden inside the model.
Independence and funding
Energy Stack does not sell anything itself. Where a topic recommends a route forward (a salary-sacrifice EV scheme, a heat pump installer, a solar installer), affiliate links may appear at the foot of the relevant page. Affiliate placements never alter the recommendation, and the article structure makes clear which sections are editorial and which links are commercial.
How it stays current
UK home energy moves quickly: tariffs change, regulation evolves, equipment generations turn over. Each page is dated, and revisions are noted at the top of the page with a short changelog. When market structure shifts (a tariff withdraws, a grant rule changes), the relevant pages are re-reviewed.
