Infrastructure and construction is the largest category of UK public investment. It includes:
- economic infrastructure such as energy and transport (the 2 largest areas of investment), broadband and communications, electricity and gas transmission, flood and coastal defence, water and sewerage, and research
- social infrastructure such as borders and policing, defence, education, health and social care, housing and regeneration, justice, tax and customs, work and pensions
Infrastructure requires a systemic, long-term view. Planning horizons are often long, and decisions can affect the lives of British people for decades. Infrastructure investment also has an important short-term role, helping support jobs and stimulate the economy. To support strategic infrastructure planning and investment:
- HM Treasury makes strategic decisions on infrastructure policy and spending
- the National Infrastructure and Service Transformation Authority, part of HM Treasury, brings together long-term infrastructure strategy with best practice project delivery as the home of Government Project Delivery, and publishes the UK Infrastructure pipeline setting out planned investment across sectors
- the National Wealth Fund provides finance to catalyse private investment to support investment and drive growth
Responsibility for infrastructure and construction policy, funding and delivery is shared between the UK government and the devolved governments, which varies depending on area.
Some areas are reserved to the UK Parliament, such as telecommunications and most of energy policy (including electricity and gas markets, nuclear and offshore oil and gas). Many other areas are devolved, including planning, roads and local transport, housing and building standards, water and sewerage, and most economic development.
Because responsibilities and consenting routes differ by nation and by sector, programmes and projects should confirm at the outset which government(s) hold policy and funding responsibility and which consenting regime applies, especially for cross‑border or offshore elements.
Infrastructure delivery can take many forms, from very large-scale single construction projects to multiple small-scale broadband and utilities projects, often rolled out as part of wider programmes. It can be a highly complex and often lengthy undertaking, requiring planning consents and sometimes legislation. It also typically involves working with multiple delivery partners from different sectors, and integration with other local and national infrastructure and services. The National Audit Office has highlighted how infrastructure programmes and projects can underperform against their ambitions, and where improvements in practices, productivity and performance are needed.
To this end, the government has set out its plan for a 10 year strategy for the UK’s social, economic and housing infrastructure to support a flourishing modern economy, drive growth, deliver net zero and support improved public services. Implementation of the strategy will be overseen by the National Infrastructure and Service Transformation Authority.
Where construction work involves the government estate, advice is provided by the Office of Government Property, which is responsible for cross-government property strategy and overseeing work to transform the public estate. Advice is also available through organisational property functions, some of whom have specific sector expertise (defence, prisons and overseas property, for example). The requirements of the Government Functional Standard for Property should be followed at all times.
Infrastructure and construction programmes and projects require considerable sector expertise and experience in their design, planning and implementation. Some initial considerations are highlighted below, but further advice and support from the relevant bodies should always be sought early in the life cycle when the requirements are being defined and validated.
