One volume on this sector, twelve findings, every figure traced to a named primary source and carried at a stated verification date. We read the National Wealth Fund commitments, the GBE-Nuclear allocation and the RAB financing framework so that you do not have to. Scroll down to see what is in it.
The National Wealth Fund committed £36.6 billion to Sizewell C; GBE’s capital allocation is £2.5 billion.
A public-finance stack for nuclear that did not exist in 2020.
The pipeline, the two financing routes, and the cross-volume anchors into grid and investment.
Where a figure is a projection it is labelled as one, and every finding carries a confidence level.
Check which financing route a project is using before you price the risk into your bid.
Track the GBE-Nuclear capital allocation against what has actually been drawn down.
Read the twelve findings with their confidence levels, rather than a headline from a press release.
See how the nuclear pipeline connects to the grid and investment volumes you already read.
The quality of the consultancy support has been excellent. They took the time to understand our requirements rather than offering an off-the-shelf solution, and worked closely with our project team throughout. We would have no hesitation in working with them again.
Nuclear new build means the power stations being built or planned to replace Britain's ageing reactors, from the two large plants at Hinkley Point C and Sizewell C to the first small modular reactors at Wylfa on Anglesey. A small modular reactor produces a few hundred megawatts (MW, a measure of how much power it can supply at once) and is made in parts in a factory, then put together on site.
Start with Sizewell C if you want work this decade. It is a second Hinkley Point C on the Suffolk coast, built to the same reactor design, and the government gave it the go-ahead on 22 July 2025 at a target construction cost of around £38 billion in 2024 prices. The government took an initial 44.9 per cent stake, making it the largest shareholder, and the National Wealth Fund will lend up to £36.6 billion.
Price your work knowing the £38 billion may not be the final cost. Parliament's Public Accounts Committee reported on 28 October 2026 that the project could cost between £40.5 billion and £47.7 billion and finish between 2039 and 2043.
Look to Wylfa next if you work in north Wales. On 13 April 2026 GBE-N, the government's nuclear delivery body, signed a contract with Rolls-Royce SMR that starts design work on three reactors with a combined output of at least 1.4 GW, or 1,400 MW. The programme is backed by £2.6 billion from the 2025 Spending Review.
| Figure | What it is | Source and date |
|---|---|---|
| £38 billion | Sizewell C's target construction cost at the go-ahead, in 2024 prices | GOV.UK, 22 July 2025 |
| 44.9% | The government's initial stake in Sizewell C, making it the largest shareholder | GOV.UK, 22 July 2025 |
| 1.4 GW | The minimum combined output of the three Rolls-Royce small modular reactors planned for Wylfa | GOV.UK, 13 April 2026 |
Expect a written answer from Sizewell C to the committee by about 28 January 2027, three months after its report. The committee also asked for a progress report to Parliament every six months rather than once a year. The government will reply formally in a Treasury Minute, its standard written response.
Keep an eye on the safety approval for Wylfa's reactors too, because your timetable there depends on it. The Office for Nuclear Regulation is in the final step of its assessment of the Rolls-Royce design, and its 2024 timetable had that step finishing in December 2026.
