Tariff setup

Setting up rate bands

A band is a stretch of the day with one price, set in 30-minute steps. Bands are always joined end to end, so there are no gaps and no overlaps: changing one band's end time moves the next band's start time to match, and the final band always runs to midnight. Adding a band splits the last one in two; you can then adjust the times. A tariff has between 1 and 4 bands. A flat rate tariff is just one band covering the whole day.

Entering rates

Each band needs a unit rate per kWh from your bill. Zero is a valid rate. The editor will not save until every band has a rate and the full 24 hours are covered; the indicator at the bottom of the editor tells you what is missing.

The standing charge

The standing charge is the fixed daily amount your supplier bills regardless of use. Enter the daily amount from your bill. A negative value is allowed, which suits some export tariffs.

What saving your tariff does

Saving applies the new rates from the start of today. The app then uses them everywhere costs appear: the weekly energy cost card, boost cost estimates, and schedule cost estimates. If the tariff was changed from another device while you were editing, the app tells you and reloads the latest version so you can re-apply your change.

Frequently asked questions

Why can I not create a gap between bands?

The editor keeps bands joined deliberately, because every minute of the day needs a price for costs to be calculated. To remove a band, delete it and its neighbour absorbs the time.

Why is the last band's end time fixed at 00:00?

The final band always runs to midnight so the day is fully covered. To change the evening price boundary, adjust the previous band's end time instead.

My tariff has more than four price changes a day. What do I do?

The editor supports up to 4 bands. Pick the four stretches that best match your tariff's pattern; the cheapest window matters most, because that is where the app aims your heating.

Do I need to add a tariff at all?

Your water heating will still work without one, but your costs cannot be shown and the Savings and Balanced goals have no price signal to plan with. Setting up your tariff unlocks both.
