Stop overpaying.
Start optimizing.
Comparison sites show you headline rates. We show you what you'd actually pay based on your real usage pattern.
No credit card required. Works with any smart meter.
Which tariff should you actually be on?
Every comparison site shows you "24.5p per kWh" and calls it a day. We pull your actual half-hourly usage and calculate what you would have paid on every tariff that exists.
