Our roundtable examined how UK infrastructure markets price resilience. Using Vallorii’s VAPRI and the new VARI index, we showed how environmental stress affects asset performance, equity returns and valuations. Discussion focused on incentives, ODIs and funding gaps, with consensus that resilience remains under-priced and needs explicit inclusion in equity returns.

Measuring the crowding-out effect and what it takes to bring private capital back to “slow” infrastructure in the UK

Projects today face a widening set of power-related uncertainties: delayed grid connections, congestion that limits deliverability, curtailment during peak hours, tightening capacity margins, and growing political scrutiny over who pays for system upgrades.

The data‑centre pipeline dominating electricity forecasts is not a construction schedule. It is a set of possibilities. Developers submit multiple applications across regions and substations, knowing that only a small share will ever be built.

Affordability does not constrain infrastructure investment directly. It acts through politics and regulation. As utility bills rise faster than incomes, tolerance for further increases falls, raising the risk of political intervention in allowed returns and cost recovery. For long-lived, capital-intensive assets, this uncertainty lifts required returns, turning affordability into a material cost of equity risk.

Infrastructure investment is increasingly shaped by affordability pressures rather than engineering or regulation alone. UK households already spend a high share of income on utilities, and bills are set to rise faster than incomes through the 2030s. This analysis examines whether future consumers will be willing and able to fund the scale of capital programmes now being proposed—and why affordability is becoming a binding constraint on infrastructure delivery.
