Why the UK is a Great Destination for Infrastructure Investment — and Why Now

The UK offers an unusually attractive entry window for long-term infrastructure investors because its stable legal and regulatory framework coincides with weak recent competition and a large pipeline of capital needs.

• UK pension portfolios allocate around 7% to infrastructure in Australia and 10% in Canada, while UK schemes are described as playing catch-up; domestic sterling assets also match pension liabilities and UK inflation more directly.
• The UK combines political stability, enforceable contracts, deep capital markets and openness to foreign ownership, despite past shocks including Brexit, RPI reform and the levy on electricity generators.
• Based on roughly 20 years of market observation, Dalmore estimates typical returns of 1–3% above the risk-free rate for investment-grade infrastructure debt, 4–6% for core equity, 5–9% for core-plus and 4–8% for high-yield strategies.
• The market has real risks: Thames Water equity investors have lost money, renewable generators faced a windfall levy, and Covid-era fibre investment suffered from cost overruns, weak take-up and higher financing costs; the article distinguishes these market or project failures from failures of the regulatory framework.
• Demand is supported by the UK government’s £725 billion ten-year Infrastructure Strategy, a project pipeline of about £530 billion and estimated economy-wide net-zero investment of around £50 billion a year by 2030; the UK also recorded almost 3,500 M&A deals worth about US$250 billion in 2024.

Takeaway: Investors deploying capital now may benefit from lower acquisition valuations and, potentially, stronger exit demand when UK pension reforms create a deeper domestic buyer base, although the upside depends on regulatory, project and sterling risks and is not part of the base case.
