What capital will fund, what the system needs
On 9 September 2026 we held the inaugural Vallorii Infrastructure Forum at Rhodes House, Oxford. 40 senior leader guests from government, regulators, utilities, investors and banks spent the day on one question: What will it take to make UK infrastructure fit for 2035, when the capital to build it exists but the certainty investors need before they commit it does not? The day had four panel sessions – macro risk, delivery, maintenance and valuation – as well as keynotes by Minister for...

When accounting shapes behavior: the hidden incentives in infrastructure valuation
In regulated infrastructure, value is not a fixed concept. The value of an infrastructure asset depends on how it is measured and which accounting basis drives returns. Different accounting frameworks produce markedly different views of the same asset base. Regulatory asset values (RAV), historical cost accounts, and current cost accounts (modern equivalent asset value, MEAV, or replacement cost), each serve distinct purposes. But when the differences between these measures changes,...

Depreciation, Affordability, and the Hidden Trade-offs in Infrastructure Investment
Infrastructure debates tend to focus on what should be built next. Yet a more fundamental question sits beneath them: how quickly should we pay for what has already been built? That question goes to the heart of depreciation. As discussions at the March roundtable underscored, it is emerging as a central lever in infrastructure economics and regulation. How does intergenerational fairness impact affordability? Depreciation directly shapes returns, bill trajectories, and risk allocation over...

From Power Procurement to Power Security
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 Phantom Data-Centre Pipeline
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.

Rising Affordability Pressure Adds 30-130bps to Electricity Network Cost of Equity
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.

Affordability is becoming a binding constraint on UK infrastructure investment
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.

Red tape: Does economic regulation have an overfitting issue?
“Overfitting” is a phenomenon in statistics where models are needlessly complex. Overfit models are very elaborate yet inaccurate . Such models look precise and sophisticated, but the precision is illusory: they reproduce the past while obscuring the future. The same dynamics can emerge in regulatory frameworks and models when detail accumulates faster than insight. Economic regulation in the UK has increased in complexity over recent decades with the introduction of cost-based regulation,...

When asset resilience becomes a valuation input
As environmental stress rises, infrastructure resilience is becoming a valuation input. Vallorii’s VARI (Vallorii Asset Resilience Index) estimates hidden asset health by linking external factors like rainfall and groundwater to failure signals such as storm overflows. The result is a clear resilience score that highlights meaningful differences between operators and supports smarter pricing, capital allocation, and risk decisions.
