Yes, 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.
For customers on fixed rate tariffs, a ‘floor’ unit price for gas averaging at 10.3p/kWh and for electricity averaging at 34p/kWh for direct debit customers will also come into effect on 1st October 2022. There is a floor price 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.
Unit price reductions of up to 17p/kWh for electricity and 4.2p/kWh for gas will apply to fixed tariff customers to bring their rates down to, but not below, the floor unit price. 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. This will ensure that a fair price is paid by everyone.
