What this log does and does not record
It records changes to standing charges on every tariff, and to unit rates on flat and banded tariffs — the moves a supplier chooses to make.
It deliberately does not record the half-hourly moves on Agile or the daily ones on Tracker. Those are the tariff doing what it says it does rather than a decision to reprice, and each is already drawn as a chart on its own page. A tariff missing from this log is not a tariff whose prices held still.
Every entry is generated from the stored prices by a template. Nothing here is written commentary, and no entry implies a view on whether a change was justified.
