Infrastructure and Planning

Overview

Infrastructure delivery is the cross-cutting operational challenge underpinning most of the government’s ambitions. The 10 Year Infrastructure Strategy (£725bn) and Planning and Infrastructure Act 2025 (Royal Assent December 2025) are the primary vehicles. NISTA is the oversight body. NSIP pre-application timelines doubled to 27+ months by 2021 — reform is urgent given multiple 2030 targets.

Strategic coherence assessment

Partly coherent. The 10 Year Infrastructure Strategy and PIA 2025 are well-integrated in intent. But:

  1. Delivery confidence: 31 red-rated GMPP projects (£198bn whole-life cost); count rising year-on-year; average cost increasing. The strategy’s ambitions are not matched by delivery confidence at programme level.
  2. Planning reform timing: PIA only in force December 2025; most provisions require secondary legislation. The 2030 targets (clean power, housing, biodiversity) need decisions now, not after implementation.
  3. Workforce: Infrastructure delivery depends on the same skills pool as IS-8 sectors; no single workforce model covers the intersection.
  4. Green Book: Revised to be simpler, but the quality of project appraisal that generates red-rated projects is unchanged structurally.

Key tensions

Open questions

  • Which GMPP projects are red-rated? What is the sector breakdown of the 31 red-rated projects?
  • What is the implementation timeline for PIA 2025 secondary legislation?
  • Is there a single cross-government skills or workforce plan covering infrastructure delivery?
