New Oxford Economics Report
Positive Economic Impact of Sizewell C
A new report, released in December 2025 by Oxford Economics shows Sizewell C will be a major driver of growth in Suffolk, the East of England and across the UK.
With £4.4bn already invested in the East of England, construction is well underway — and the benefits will extend nationwide, with a third of economic gains and over two-fifths of jobs created outside the region.
