Battery + tariff, matched
We pick a plug-and-play battery that suits a flat or a rented home, match it to a tariff that rewards charging overnight and discharging at peak, then watch the market and tell you when a better tariff comes along.
How it works
Two minutes, no billing details. This tells us which tariffs you're eligible for.
We show tariffs with a real gap between the cheap overnight rate and the expensive peak rate, the kind that make a battery worth having.
Buy through our Amazon link, switch through the supplier's link. Both are yours, we don't hold either.
Roughly once a week. If a better eligible tariff appears, you get an email with the saving and a link to move.
Every battery we list can charge from the grid, not just from solar. That's what makes the economics work, charge when power is cheap overnight, use it or export it when power is expensive at peak. We only list units suited to flats and rented homes, plug-and-play, no rewiring. Where a battery isn't a fit for your situation, we say so.
Time-of-use and dynamic tariffs only pay off if your battery can use them. We match you to a tariff with a real gap between its cheapest and most expensive rate, check what you're eligible for (a smart meter is usually required), and keep checking after you switch. When a better one appears, you hear from us first.
Before you register
We never ask for your bank details, payment card, or existing supplier account number. Registration needs your name, email, postcode and smart meter status, nothing else.
Every saving figure we show is based on typical household use, not your actual bill, because we don't collect your consumption data. Treat any figure as a guide, not a promise.
We earn a fee from Amazon on battery purchases and an introducer fee from suppliers on tariff switches, including repeat switches. Full detail is on our trust and disclosures page.
