What the project is for

The Strategic Sites Accelerator is a key Industrial Strategy programme designed to unlock nationally significant investment opportunities and accelerate their path to delivery. Over the pilot period, we will support a small number of genuinely transformative sites, combining technical expertise with flexible financial tools to help crowd in private capital and unlock investment at pace. Backed by around £600 million of Financial Transactions funding, the Programme is focused on deploying capital where government intervention can be catalytic and help unlock opportunities that may not otherwise progress. The Programme is designed to tackle barriers that can slow down investment, helping strategic sites become investment-ready more quickly.

Departmental delivery commentary

The Delivery Confidence Asssessment rating remains AMBER. Independent assurance concluded that the programme is well developed, with a clear strategic rationale, commercial model and delivery approach. While the programme is progressing well, it remains subject to final HM Treasury approval and has not yet been fully mobilised, meaning some delivery arrangements are still being finalised.
