The question

To ask the Secretary of State for Energy Security and Net Zero, how much funding his Department has allocated to support Sizewell C nuclear plant in advance of the final investment decision for that plant.

Answered by Michael Shanks

The Sizewell C Development Expenditure Subsidy Scheme (DEVEX Scheme) has been made for £5.5bn for the Sizewell C company. Under this scheme to date, £3.9bn has been awarded to the company, in two tranches, one of £1.2bn and one of £2.7bn.

Prior to these awards, the Department had awarded £2.5bn to the project since the Government Investment Decision in November 2022 under the SZC Investment Funding Scheme.

Hence, in total, the Department has to date allocated £6.4bn to the project under both subsidy scheme.
