Oct 1st 2022 changes.
"
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 in Great Britain from 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.
The Energy Bills Support Scheme (£400 discount) will also be applied as a monthly or quarterly discount to your bill."
"
If you’re on a fixed rate tariff
Fixed tariff customers will have the same support where appropriate. Unit price reductions of up to 17p/kWh for electricity and 4.2p/kWh for gas will apply to fixed tariff customers that currently have unit rates above the EPG.
A ‘floor’ unit price for gas averaging at 10.3p/kWh and for electricity averaging at 34p/kWh for direct debit customers will be introduced, because some people will have fixed at much lower prices some time ago, meaning their annual payments will already be below the £2,500 average set by the Energy Price Guarantee.
Customers on fixed rate tariffs that are already below the floor unit prices will continue to enjoy those low rates, but will not receive a further discount for the duration of their fixed term.
For the small number of consumers who fixed at a high rate exceeding the October Ofgem price cap of £3,549, they will receive the full discount of 17p for electricity and 4.2p for gas. However, given the higher starting point, their fixed rate tariff will still have a unit rate that is above the EPG rates.
Energy suppliers will adjust fixed tariffs automatically. Customers on fixed tariffs do not need to take any action to get the benefits of this scheme. Any transfer to a different tariff is a matter for suppliers.
The Energy Bills Support Scheme will be paid on top of this as a monthly or quarterly discount to your bill, totalling £400 from October to March."
"
Standing charges
Average standing charges for customers on default tariffs will remain capped in line with the levels set (in Great Britain) by Ofgem for the default tariff cap from 1 October, at 46p per day for electricity and 28p per day for gas, for a typical dual fuel customer paying by direct debit. Standing charges for households in Northern Ireland will also be unaffected."
