Tariff mechanics
A growing share of battery quotes now reference Octopus Agile, but not every installer can explain it clearly on the spot. Here's the version worth having ready for a sales call.

View the demo →Octopus Agile is a UK electricity tariff where the price changes every half hour based on wholesale market conditions, instead of staying fixed all day — meaning the same unit of electricity can cost several times more at peak times than during a cheap overnight window.
A battery lets a customer charge during the cheapest half-hour windows and draw on stored power during the expensive peak windows — turning a genuinely volatile daily price swing into a predictable saving, rather than a theoretical one.
Quoting battery savings against a flat, single-rate tariff understates the case — the real opportunity only becomes visible once the actual cheap/peak price gap on a time-of-use tariff is shown, which is exactly what a live calculator using real tariff data demonstrates rather than just claims.
No — it's equally useful for explaining why switching to a time-of-use tariff alongside a battery often improves the numbers further.
No, it moves with wholesale market conditions — which is exactly why showing a live, current estimate is more convincing than quoting a fixed, generic saving figure.
