I saw this in the government's plan.
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.
These unit prices have been passed to suppliers to ensure that they are used to calculate bills on time for 1 October.
Energy suppliers will adjust standard variable tariffs automatically. Customers on standard variable tariffs do not need to take any action to get the benefits of this scheme.
I also read that
If you’re on a fixed tariff
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.
These unit prices have been passed to suppliers to ensure that they are used to calculate bills on time for 1 October.
As Next Online V19 was something like electricity 60p per unit and gas 15p surely we'd be better changing to SVR as electricity will cost 34p on SVR compared to the 60-17= 43p if on a fixed tariff?
