Afternoon. I know there are loads of threads on this but I haven't seen anyone post the govt information.
They posted a fact sheet online here: www.gov.uk/government/publications/energy-bills-support/energy-bills-support-factsheet-8-september-2022
Which confirms;
If you’re on a fixed tariff at a higher rate caused by recent energy price rises, your unit prices will be reduced by 17p/kWh for electricity and 4.2p/kWh for gas.
If you’re on a standard variable tariff
The average unit price for dual fuel customers paying by direct debit will be limited to 34.0p/kWh for electricity and 10.3p/kWh for gas, inclusive of VAT, from 1 October.
If you’re on a pre-payment meter
For GB pre-payment meter customers, the Energy Price Guarantee will be applied to the rate you pay for each unit of energy, so the money you put on the meter will last longer than would otherwise have been the case this winter.
Worth reading in full - but hope this helps. In a nutshell, your bills should come down from 1st Oct.
