The government’s major projects
Last updated . Figures refresh every night. How each figure is worked out.
In March 2026 the Government Major Projects Portfolio held 189 projects. Of the 81 with an independent delivery confidence rating, 24 were rated red, 51 amber and 6 green. Red is the lowest of the three ratings; the authority defines each in its annual report. The projects with a published whole-life cost total £437.7bn (2024-25 real prices, as the file states). Source: NISTA Major Projects Annual Report 2025-26.
Key figures
- 189Projects in the portfolio down on a year earlier: −24 (−11.3%) vs March 2025
- 24Rated red by the independent assessors up on a year earlier: +4 (+20.0%) vs March 2025
- £437.7bnWhole-life cost of the 132 projects with a published figure In 2024-25 real prices: not comparable with March 2025
What is the short version?
- The scale has changed: it had five points before March 2022, and from the 2024-25 data each project carries either the independent rating or the department’s own, so fewer have an independent one.
- Costs cover only the projects that publish one: 132 of 189 in March 2026. Some ratings and costs are withheld under the Freedom of Information Act.
- Totals are not comparable across that change: the March 2026 file gives costs in 2024-25 real prices; earlier files mostly in cash.
- A rise in a project’s cost is not necessarily an overspend: a change in scope, in timing or in how costs are counted moves it too.
How have the ratings changed over time?
- Red 30% 24 of 81
- Amber 63% 51 of 81
- Green 7.4% 6 of 81

Numbers of projects, every panel on the same scale from zero. From the 2024-25 data a project carries either the independent rating or the department’s own, so part of the fall in independent ratings comes from that change.

Why the years are not quite like for like
The independent rating is the Infrastructure and Projects Authority’s delivery confidence assessment, now made by the National Infrastructure and Service Transformation Authority. From the 2024-25 data a project carries either that rating or its senior responsible owner’s own rating, not both, so the number with an independent rating has fallen. Before March 2022 the scale had five points; this table starts when it became red, amber and green. Some ratings and costs are withheld under the Freedom of Information Act, which is why not every project has a figure. Costs are not adjusted between years except where the file says so: the March 2026 file gives costs in 2024-25 real prices.

Projects are matched to the year before by their portfolio ID. A difference in whole-life cost can come from a change in scope, in timing or in how costs are counted as well as from overspending, and the two years’ figures may be on different price bases (see above), so the difference is shown as published and not explained here. Each department’s commentary on its projects is in the source file.
