Key facts and evidence

Within the UK, this page covers Great Britain prepayment rates as of 13 August 2026. The conclusion is to pair charging kWh with the prepayment row only for a matching account and region. E2 limits these VAT-inclusive values to 2026-07-01 through 2026-09-30; the benchmark alone does not state the user's total cost.
