Octopus Energy has announced its standard tariff will be £50 cheaper than the April price cap - but only for existing customers.
The new rate applies to the Octopus Flexible variable tariff, although it is unlikely to ease the financial burden too much for struggling families as energy costs continue to rise.
Octopus Flexible is being quoted at £1,921 a year for someone with typical energy use, while the price cap will jump to £1,971 for direct debit customers, up from the current level of £1,277.
