Railway & Underground Railway Construction in the UK Industry Data and Analysis
Rail construction companies work under contract from public-sector bodies funded by the Department for Transport to develop and maintain the UK rail network. Network Rail organises investment in rail into five-year cycles called Control Periods (CP), which can induce volatility – revenue typically peaks in the middle of investment cycles before tailing off at the end. The start of CP7 in April 2024 led to a variety of project rollouts, largely for rail maintenance across the UK. Alongside this, the continuation of HS2 Phase 1 is bolstering revenue growth for both large and small rail construction companies. Over the five years through 2026-27, revenue is set to climb at a compound annual rate of 4.1% to reach £3.1 billion, including an estimated 8.4% jump in 2026-27 as HS2 construction and CP7 spending pick up. Labour shortages in the UK construction sector have significantly affected the industry. Sourcing skilled specialists has become increasingly difficult, limiting contractors' capacity to participate in projects and constraining revenue growth. Nonetheless, profit is set to swell in 2026-27 as Network Rail shifts more work towards performance-based contracts, such as the Southern Integrated Delivery alliance, which ties contractor profit to cost-efficiency targets rather than hours worked, rewarding companies that control costs. Efficiency has become a top priority for Network Rail in CP7, which has raised its savings target for CP7 to £4.1 billion, from £3.9 billion in CP6. Revenue is forecast to edge up at a compound annual rate of 1.9% over the five years through 2031-32 to £3.4 billion. The government's decision to scrap HS2 Phase 2 dealt a huge blow to the industry’s growth prospects, though tunnelling towards Euston restarted in January 2026 as part of a wider reset. As net-zero looms, electrification projects, currently running well below the government's annual target, may see greater adoption, improving revenue prospects for specialised contractors. The upcoming shift to Great British Railways (GBR), a single public body that will manage the UK's rail systems from around summer 2027, is creating some hesitancy. While GBR could make procurement easier for many suppliers, it could also consolidate small regional projects into single schemes, making it harder for SMEs with limited construction capacity to win contracts. This could minimise competition across the industry and raise market share concentration.
