The Department for Transport’s latest annual report and accounts reveal the scale of the UK transport construction pipeline, with more than £20bn of capital spending moving through rail, roads, HS2, local transport, highways maintenance and major infrastructure programmes during 2024 to 2025.
For the construction sector, the report is more than a departmental accounting document. It gives a useful view of where government-backed transport infrastructure is being funded, where work is advancing, where programmes are being reset, and where delivery pressure is likely to remain high across the next spending period.
The key number is the Department for Transport’s capital delivery position. The department reported a capital DEL budget of £20.666bn for 2024 to 2025 and capital DEL outturn of £20.523bn. That spending sits across some of the UK’s most important construction and infrastructure assets, including HS2, Network Rail, National Highways, local transport funding, road renewals, rail upgrades and strategic transport programmes.
The construction message is clear: transport remains one of the UK’s largest public-sector construction markets. But the DfT accounts also show a sector under pressure, with major projects being reset, road schemes cancelled, resource spending constrained and delivery expectations increasing across rail, roads, local transport, housing-linked infrastructure and decarbonisation.

What This Means
The Department for Transport annual report covers the period from 1 April 2024 to 31 March 2025 and sets out the department’s spending, assets, liabilities, priority outcomes and delivery progress. For contractors, consultants, suppliers and infrastructure investors, the most useful reading is not simply the headline spend. It is the pattern of investment and pressure behind the numbers.
Transport infrastructure is central to government growth policy because it affects access to jobs, housing, freight, regional productivity, logistics, regeneration and private investment. The DfT report links transport delivery to economic growth, housing, freight, clean energy, public health, accessibility and resilience.
That makes the report directly relevant to UK construction. Rail upgrades, road renewals, local transport schemes, station works, bus infrastructure, electric vehicle charging, walking and cycling routes, highways maintenance, bridges, tunnels, depots and strategic road projects all require design, engineering, construction, materials, specialist labour, programme control and supply-chain capacity.
By the Numbers
| Area | DfT Reported Position | Construction Relevance |
|---|---|---|
| Capital DEL budget | £20.666bn in 2024 to 2025. | Shows the scale of government-backed transport capital delivery. |
| Capital DEL outturn | £20.523bn. | Indicates substantial capital spending actually moved through the system. |
| Total DfT assets | Around £696bn at 31 March 2025. | Reflects the enormous asset base maintained, renewed and enhanced by the transport construction supply chain. |
| Railway network assets | Around £490bn. | Shows the long-term importance of rail maintenance, renewals and enhancements. |
| Strategic road network assets | Around £152bn. | Supports continued highways maintenance, bridge works, renewals and capacity schemes. |
| HS2 assets under construction | Around £38bn. | Confirms HS2 remains a major construction programme despite reset and cost scrutiny. |
A £20bn Transport Construction Pipeline
The DfT accounts show a capital programme that remains heavily dependent on construction delivery. Major areas include HS2, Network Rail, National Highways, local transport funding, the strategic road network, rail renewals, road maintenance, East West Rail, the Transpennine Route Upgrade and local infrastructure programmes.
The report says the department continued to invest in key infrastructure to support growth through maintenance and renewals, including £1.2bn invested into the strategic road network. It also points to longer-term benefits through major projects such as HS2, East West Rail and the Transpennine Route Upgrade.
For the construction market, this matters because transport remains one of the few areas where government-backed capital spending can create multi-year demand for civil engineering, structural works, tunnelling, rail systems, highways, bridges, stations, depots, utilities, groundworks, specialist testing, temporary works and project controls.

HS2 Remains the Biggest Construction Signal
HS2 remains the most visible major project in the DfT construction portfolio. The report says HS2 Ltd had completed 73% of tunnel drives across the route and recorded major engineering milestones, including assembly of the Colne Valley viaduct’s 2.1-mile deck, making it the UK’s longest rail bridge. The accounts also show around £7bn of additions relating to HS2 construction works during the year. That confirms that, despite political scrutiny and programme reset, HS2 remains a major source of construction activity, specialist civil engineering demand and supply-chain exposure.
The government is also committed to bringing HS2 to Euston, with funding confirmed to proceed with tunnelling from Old Oak Common to the central London terminus. For London construction, that is one of the most important parts of the report because Euston and Old Oak Common sit at the centre of rail, regeneration, housing and commercial development potential. The report also references research predicting that HS2 could add £10bn to the West London economy over the next 10 years, with more than 22,000 new homes and over 18,000 new jobs within the Old Oak Common impact zone. That makes HS2 not only a rail scheme, but a regeneration and construction pipeline issue.
Rail Upgrades: Transpennine, East West Rail and Network Rail
Network Rail remains central to the transport construction market. The report says the first year of Control Period 7 had concluded, with a ring-fenced budget of £44.1bn over five years in England and Wales to support operations, maintenance and renewal of the existing rail infrastructure. Rail network additions during the year included £2.5bn of enhancements and £3.7bn of renewals. Major schemes included the Transpennine Route Upgrade, Midland Main Line and East Coast Main Line route enhancements, on-network works relating to East West Rail and improvements at East Kilbride in Scotland.
The Transpennine Route Upgrade remains one of the most important northern rail construction programmes. The report says an additional £415m funding injection was announced in spring 2024, with £7.4bn committed to date, representing around 70% of the expected cost at the time of reporting. East West Rail also remains a major growth-linked scheme. The report says the infrastructure for connection stage 1 was completed in December 2024, with services between Oxford, Bletchley and Milton Keynes due to commence later. The wider Oxford to Cambridge corridor remains significant because of its links to housing, science, research, technology and regional growth.
Roads, Renewals and Highways Maintenance
The roads position is equally important for construction. The strategic road network remained a major focus, with £1.2bn invested in maintenance and upgrades. The report says the programme focused particularly on freight resilience, which is important for ports, airports, logistics, distribution centres and regional supply chains. Additions to the strategic road network included £2.4bn of capital enhancements and £1.2bn of asset renewals. Significant additions included the M6 Lune Gorge structure scheme and the M62 Ouse Bridge joint replacement project.
The report also confirms a £500m funding uplift for local highway maintenance for 2025 to 2026. For the construction sector, that supports the continuing workload around road surfacing, drainage, bridges, footways, local highway repairs, junction improvements and resilience works. However, highways is also where the delivery pressure becomes visible. The report refers to cancelled capital projects, including the A303 Stonehenge and A27 Arundel Bypass road schemes, and records £428m of impairments in 2024 to 2025 arising from cancelled road schemes through the 2024 Spending Audit and Autumn Statement.
Lower Thames Crossing and Major Road Investment
The Lower Thames Crossing remains one of the most significant future infrastructure signals in the DfT report. The scheme is described as a new 14.3-mile road and tunnel under the River Thames, connecting Kent and Essex and almost doubling road capacity across the river east of London.
The report says the Lower Thames Crossing was granted development consent in March 2025. It also notes that DfT and National Highways were exploring funding options, including private finance.
For construction, Lower Thames Crossing matters because it would create a major civils, tunnelling, highways, environmental mitigation, logistics and supply-chain programme. It is also important because the project sits at the intersection of congestion relief, freight movement, regional growth, environmental scrutiny and net-zero construction expectations.
Local Transport, Devolution and Regional Construction Workload
The report also gives a useful signal for regional contractors and local infrastructure suppliers. DfT’s City Region Sustainable Transport Settlements are now more than halfway through the first five-year period, with many schemes moving from development into delivery. The report notes that Transport for City Region settlements will follow from 2027 to 2028 through to 2031 to 2032, with funding increasing to £15.6bn. More than £500m of that funding has been brought forward into 2025 to 2026 and 2026 to 2027 to support preparation and early delivery.
This matters because local transport funding often turns into practical construction packages: bus stations, interchanges, road maintenance, active travel corridors, local junctions, transport hubs, station improvements, walking and cycling infrastructure, ferry landings and urban realm works. The report points to examples including the £20m Halifax bus station project, the Northeast Mayoral Combined Authority’s £563m CRSTS1 plan, Greater Manchester’s Bolton carriageway maintenance scheme, Leicester’s £40m Transforming Cities Fund programme and Portsmouth’s £60m Transforming Cities Fund programme.
The Delivery Pressure Behind the Pipeline
The headline capital numbers are positive for the construction sector, but the report also shows clear pressure. DfT says its resource spending is forecast to reduce over the Spending Review period, while capital spending will continue to increase. That combination matters because complex capital programmes still require client capability, approvals, project management, commercial controls and regulatory coordination.
The report also says ongoing spending efficiencies are required across the core department’s activities and that financial support to train operating companies remains above pre-pandemic levels. This creates a difficult delivery environment: more capital investment is expected, but public bodies are under pressure to control operating costs, reduce subsidy and improve value for money.
For construction firms, this can mean more scrutiny over cost, programme, claims, design maturity, risk transfer and value engineering. It can also increase pressure on delivery teams where public clients need to show progress against government growth, housing, decarbonisation and regional connectivity commitments.
Key Voices on Transport Delivery
The Rt Hon Heidi Alexander, Secretary of State for Transport, said in the report that transport can connect people to opportunities, attract investment to regenerate town centres and support the homes the UK needs. The construction implication is direct: transport investment is not just about movement; it is also a platform for housing, regeneration and local economic development.
Jo Shanmugalingam, Permanent Secretary, said transport is fundamental to opportunities for people and to generating future growth. That statement reflects the wider role transport infrastructure plays in productivity, access to work, freight reliability, regional planning and long-term public investment.
Nick Joyce, Director General for the Corporate Delivery Group, said the Spending Review settlement protects vital public transport services, maintains and renews infrastructure and invests in the long-term future of the transport system. For construction, the important point is the balance between capital investment and affordability risk.
What This Means for the UK Construction Sector
| Area | DfT Direction | Construction Impact |
|---|---|---|
| Major rail | HS2, East West Rail, Transpennine Route Upgrade and Network Rail renewals remain active. | Supports demand for civils, rail systems, tunnelling, stations, depots, structures and specialist supply chains. |
| Highways | Strategic road network renewals and maintenance remain significant, but some road schemes have been cancelled. | Creates workload but also increases uncertainty around scheme prioritisation and affordability. |
| Lower Thames Crossing | Development consent granted, with funding options being explored. | Potential major civils and tunnelling opportunity, but timing and funding remain key issues. |
| Local transport | CRSTS, TCR settlements and local transport funding support regional schemes. | Creates opportunities for regional contractors, highways firms, active travel specialists and urban infrastructure suppliers. |
| Housing-linked infrastructure | DfT links transport planning with housing growth and development sites. | Transport schemes may become more closely tied to regeneration, new towns and housing delivery. |
Why London Construction Should Watch This
The London relevance is strongest around HS2, Euston, Old Oak Common, rail capacity, TfL, Elizabeth Line rolling stock and the wider regeneration effect of transport investment. The report confirms that the government is continuing work on affordable, integrated plans for the HS2 station and wider Euston station campus.
For London contractors and consultants, the key issue is timing. Euston has long been one of the most important but complicated transport-led regeneration opportunities in the UK. If the funding, station design, delivery model and private investment structure become clearer, it could unlock major work across station construction, enabling works, utilities, public realm, over-site development, logistics and commercial development.
The report also shows that the previous TfL capital settlement ended in 2023 to 2024, with a smaller 2024 to 2025 grant supporting procurement of additional rolling stock for the Elizabeth Line. That points to a more selective funding environment for London transport, where specific priorities may be supported but broad capital settlements remain tightly controlled.
The Real Market Meaning
The DfT accounts should not be read as a simple good-news pipeline story. They show large-scale public construction demand, but also the realities of delivery pressure, cancelled schemes, affordability constraints and the need to control major project cost.
This is important because the construction market is still dealing with inflation, labour pressure, design risk, insolvency exposure, procurement caution and supply-chain fragility. A large public pipeline helps, but only if projects are properly funded, designed, procured and delivered with realistic risk allocation.
The report points to a market where transport remains a major opportunity, but where contractors will need to be selective. The most attractive work will be where funding is secure, scope is mature, client decision-making is clear and risk is priced properly.
What Contractors Should Watch Next
Contractors, consultants and suppliers should watch the HS2 reset, Euston delivery model, Lower Thames Crossing funding position, Road Investment Strategy 3, Network Rail Control Period 7 delivery, East West Rail development, Transpennine Route Upgrade procurement, local transport settlements and the next phase of city-region transport funding.
They should also watch how transport devolution changes procurement routes. More funding moving through mayoral combined authorities and local transport bodies could create more regional opportunities, but it may also create a more fragmented client landscape with different standards, procurement processes and delivery expectations.
For smaller firms, highways maintenance, local transport, active travel, EV charging, station upgrades and regional transport hubs may be more accessible than major rail or tunnelling programmes. For larger contractors, the key opportunities remain around HS2, rail upgrades, strategic roads, Lower Thames Crossing, Network Rail and National Highways frameworks.
Evidence-Based Summary
The DfT accounts reveal a major transport construction pipeline, but also significant delivery pressure.
The department reported a capital DEL budget of £20.666bn and capital DEL outturn of £20.523bn for 2024 to 2025.
Major construction-related programmes include HS2, Network Rail, National Highways, East West Rail, the Transpennine Route Upgrade, local transport funding, road renewals and the Lower Thames Crossing.
The opportunity for construction is large, but the risk is equally clear: cost control, funding certainty, project resets, cancelled schemes and delivery capability will shape how much of the pipeline becomes profitable work.
