UK home energy reference

A reference for the UK home energy stack.

Solar, battery storage, EV chargers and the suppliers and tariffs that connect them. Structured to be browsed, technically honest about what is and is not known and willing to update its picks when the evidence shifts.

The stack

Why this exists

A consumer voice for a noisy market.

The UK home energy market is moving fast. New tariffs every month, new battery chemistries, V2G arriving in the mainstream, smart meters finally working. Most of the consumer-facing material trying to explain it is either too thin or too commercial to actually answer the questions people have.

Energy Stack tries to fill the gap. Reference material that takes the reader seriously, recommendations that show their working and articles that get specific about which households the advice applies to.

Recommendations with reasoning

Current pick per category, with the analysis behind it. When the pick changes, the reason and the previous pick both stay on the page.

Real numbers, not press releases

Calculator outputs show their working. Performance claims come with the conditions they were measured under.

Wrong out loud

When something here turns out to be wrong, the page says so and explains what changed. Old recommendations do not silently disappear.

What's coming

This is a living site. The first sections to land properly are batteries, solar and the energy supplier comparison, because those are where the choices are most consequential and most badly explained elsewhere. Tools and the knowledge base will fill out from there.

  • · Per-category recommendation pages with version history
  • · Knowledge base entries on the concepts that confuse people most
  • · Calculators for solar self-consumption, battery payback and tariff fit
  • · Long-form articles working through the decisions that matter
