How far back our record goes
A tariff cannot show a change from before we were storing its prices, so a short list of entries can mean a short record rather than a price that held still. This is the first date we hold a price for each tariff in the log.
- PAYG Standard VariableRecorded from 1 April 2021
- Prepay Standard VariableRecorded from 1 April 2021
- Standard VariableRecorded from 1 April 2021
- Heat Pump Tracker 36mRecorded from 21 March 2024
- Heat Pump & Save TrackerRecorded from 3 April 2025
- Empower Tracker Exclusive 12m v2Recorded from 15 December 2025 — inside the period this log covers
- FreePhase Dynamic 12m v2Recorded from 9 March 2026 — inside the period this log covers
This log covers 20 September 2025 to 20 September 2026. A tariff recorded from a date inside that period has a shorter history here than the period suggests, and its earlier moves are missing from our record rather than from the tariff.
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.
It also cannot record a change from before we held that tariff’s prices. Our record starts on a different date for each tariff, and those dates are listed above.
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.
