Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if his Department will make an estimate of the number and proportion of Energy Bills Support Scheme vouchers that were delivered late due to Royal Mail delays in the 2022-23 financial year.

The Department does not hold the data that would allow us to make an estimate.

Expectations set for suppliers factored in small delays in postage and suppliers and voucher providers had contingencies in place during postal strikes.

Vouchers that are expired due to loss, damage or not having been received can be reissued by suppliers and will have an expiry date of 30 June 2023.
