The eligibility criteria are the same as for the current EBRS scheme. For details of the EBRS see our Insight, UK Government unveils Energy Bill Relief Scheme.
Like the current scheme, there is a discount on the unit prices of gas/electricity once they rise above a threshold. The discount is capped. The threshold and the level of discount are much lower than under the current scheme. This is partly because the government cannot afford to keep supporting businesses at this level; and partly because energy wholesale prices have come down since last autumn, although they are still well above pre-June 2021 levels.
The new EBDS offers a higher level of support for 'Energy and Trade Intensive Industries' (ETII), which are those listed here: List of sectors eligible for the Energy and Trade Intensive Industries (“ETII”) scheme. Businesses that think they are eligible will have to apply for support under this scheme; it isn't automatic. Further details are to follow.
Suppliers automatically apply the discount (in the case of ETIIs, once they are approved for the increased level of support) and the government compensates the suppliers (as in the current scheme).
The detail will be set out in regulations made under the Energy Prices Act 2022. Those regulations are yet to be made.
