The Institution of Engineering and Technology has joined 27 engineering, infrastructure, and construction organisations in calling for the incoming UK Prime Minister to maintain the country’s long-term infrastructure strategy.
The joint letter, coordinated by the Institution of Civil Engineers, urges continuity around the 10-Year Infrastructure Strategy and associated project pipeline. The signatories argue that infrastructure planning needs confidence and stability, with repeated changes in direction creating uncertainty for investment, project delivery, skills development, and industrial capacity.
The intervention follows renewed political uncertainty in Westminster and comes only a year after the publication of the UK’s long-term infrastructure strategy. The strategy and accompanying pipeline are intended to provide a long view of investment across energy, transport, water, digital networks, social infrastructure, and climate resilience.
The IET’s involvement adds a systems engineering dimension to the call. Modern infrastructure is no longer a set of isolated assets. Energy, communications, transport, water, data, and industrial systems are increasingly interdependent, with failures or delays in one area affecting the performance of others.
Electrification depends on grid reinforcement, digital infrastructure depends on power availability, and industrial growth depends on transport, water, planning, and energy capacity. A national strategy that treats those systems separately will struggle to support projects that already operate across them.
The UK’s infrastructure workload is placing heavy demand on engineering consultancies, contractors, manufacturers, utilities, and specialist suppliers. Framework activity continues across public sector delivery, including AtkinsRéalis’ appointment to a major UK professional services framework covering built environment, defence, nuclear, flood risk, asset management, and wider public infrastructure programmes.
Long-term strategy still has to be converted into delivery. Planning reform, consenting capacity, procurement routes, technical standards, grid connections, workforce availability, and client capability all determine whether projects can move from announcement into contractable scope. The letter warns against disrupting those mechanisms before they have had time to mature.
Policy volatility creates practical problems for engineering companies. Businesses invest in people, equipment, digital tools, regional offices, apprenticeships, and supply partnerships on the basis of expected workload. When programmes are delayed, paused, or redesigned, that investment becomes harder to justify, leaving the delivery base thinner at the point when project demand increases.
Infrastructure also carries a manufacturing dimension. Grid projects need transformers, switchgear, cables, protection equipment, steelwork, control systems, battery systems, substations, and civil materials. Rail and transport upgrades draw on signalling, rolling stock, power systems, fabricated structures, and precision components. Water and flood projects require pumps, valves, sensors, pipework, treatment equipment, instrumentation, and control platforms.
Uncertain project timing therefore affects manufacturing order books as well as construction schedules. A stop-start pipeline can push suppliers into defensive planning, weaken apprenticeship intake, and make it harder to justify investment in domestic capacity. Long-term infrastructure planning gives manufacturers a clearer basis for tooling, recruitment, stock strategy, and supplier development.
The skills challenge is equally exposed. Apprenticeships and graduate routes need visible demand to remain credible, particularly when engineering competes with other sectors for technically capable entrants. The IET has consistently emphasised the need to change perceptions of engineering and expand participation across the profession. Continuity in national infrastructure planning helps turn that message into tangible careers.
Resilience adds another layer. Climate adaptation, energy security, digital continuity, and industrial competitiveness cannot be handled through short political cycles. Assets commissioned in the next decade will remain in service for decades, and design choices made now will shape maintenance cost, carbon performance, safety, reliability, and regional productivity well beyond the current parliament.
The call for continuity does not remove the need for scrutiny. Major infrastructure projects still need to prove value, manage cost, reduce carbon, and address local impacts. Frequent strategy resets, however, risk spending time and money on revised studies, consultations, and governance structures while the physical assets remain delayed.
The incoming Prime Minister will inherit an infrastructure programme that is technically demanding, fiscally constrained, and closely tied to industrial competitiveness. The engineering sector is asking for the political space to deliver what has already been identified as necessary.
