Energy Price Guarantee: regional rates, January to March 2023

Updated 24 November 2023

Applies to England, Scotland and Wales

The Energy Price Guarantee unit rates for standard variable tariffs are shown below. These are the maximum unit rates suppliers can charge for tariffs that are subject to the Ofgem price cap in effect from 1 January to 31 March 2023. Suppliers can also charge less than these rates.

The cap is based on Ofgem’s assessment of the costs incurred by a nominal efficient supplier and these vary by fuel, payment type, meter type and region. Price rises may be higher for customers who pay on receipt of bills and those on Economy 7 meters, as Ofgem’s assessment of the costs of supplying those customers has increased more than Direct Debit dual fuel customers who act as the benchmark for setting Energy Price Guarantee rates.

For customers on multi-register tariffs such as Economy 7, suppliers have flexibility to apply slightly different discounts to the individual rates within the tariff, helping to balance out the reduction of more expensive day rates with cheaper night-time electricity rates. Each supplier will approach this differently.
