The annual budget for the financial year 2024/25 is £180million, with the ability to over-allocate vouchers up to £250million.
The scheme was originally due to end in 2025, but an additional £1.5billion was allocated to extend it to 2028.
Categories (and values) for the current financial year budget are:
- Budget provisionally allocated - £8,937,500 - this includes all undetermined applications. The budget cannot be allocated until property owner consent is received.
- Budget allocated - £31,472,500 - this is a dynamic value, as vouchers expire or return then more budget becomes available for future vouchers to be issued.
- Budget committed - £115,410,000 - this is the total value of vouchers that have been paid within this financial year.
- Budget available - £24,180,000 - this is the total amount of budget not utilised within any of the other categories.
- Over-allocation amount - £70,000,000 - this is the total value remaining for Ofgem to over-allocate vouchers above the current financial year budget.
