CIVIC·ENGINE
Civic Engine Ltd · Regulatory Economics

The regulatory cycle, modelled end to end.

PolicyBox® holds the allowed returns regulators set across 32 energy markets, 72 US investor-owned utilities, UK water and telecoms. Each is traced to the decision that set it, with the tools to rebuild it on the regulator's own method and to see which way the next reset moves.

Platform

One model per market, not one model for all markets.

Regulated returns are set by formula, and every regulator's formula is different. PolicyBox holds each determination as the regulator published it, with the allowed return and its components on the regulator's own basis, and implements each market's own method: its risk-free rate convention, its approach to beta and gearing, its indexation, its control period structure.

Simulation, not just data. The platform goes beyond reporting published determinations. It reconstructs the mechanics behind them, so you can stress assumptions, run counterfactuals and see how allowed returns respond as market inputs move. Where a regulator's published method can be reproduced, it also shows which way the next decision moves.

Government bond yields are read live and stored with full history. Determinations are held against a sourced baseline: a self-audit re-checks the markets in rotation every night, and every dated regulatory event is watched as it approaches.

Capabilities

From determination to the next reset.

Each module answers a question regulatory teams actually ask, on each regulator's own terms, then extends it with the analysis published documents cannot give you.

Allowed returns, sourced

Every determination's allowed return and its components, one row per market, each cited to the regulator's decision and graded by confidence.

Market intelligence

One market's file: the allowed return and its source, the reset outlook, peers, the asset base and the dated regulatory history.

Reset outlook

Which way each regulator's own formula moves next: a methodology projection, not a prediction. A track record scores registered forecasts against the decisions that follow.

Cost of capital

Rebuild any market's WACC on its regulator's method, with live risk-free and beta inputs, and test the assumptions that move it.

Price control and adequacy

The RAB waterfall, financeability and the breakeven WACC, and the probability that the allowed return covers the required return.

Across sectors

US, UK and EU allowed equity returns on one normalised basis, and every dated regulatory event, in every sector, in one calendar.

API · The underlying parameters, cross-market comparisons, reset projections, water and telecoms, through an authenticated REST API for portal clients.

Coverage

Built for cross-market work.

The same questions, answered consistently across jurisdictions, on each jurisdiction's own terms.

Sourcing

Every figure traces to the decision that set it.

Anything that cannot be sourced is labelled as estimated or pending, never guessed.

Cited to the determination

Each allowed return, and each of its components, names the regulatory decision it comes from, with a confidence tier that says how it was verified.

Gaps said plainly

Where a regulator publishes no figure, or its document cannot be read, the platform says so rather than filling the gap.

Checked every night

A self-audit re-checks the markets in rotation every night against a sourced baseline, and each dated regulatory event is watched as it approaches.

Forecasts on the record

Projections are registered before the decision they target, and scored only against decisions published afterwards.

Who it serves

For every side of the regulatory process.

Networks and utilities

Benchmark your allowed returns against peers and prepare for the next control period with the regulator's own mechanics.

Investors and infrastructure funds

Assess regulated cash flows and return frameworks consistently across markets before capital is committed.

Regulators and policymakers

Compare methodologies internationally and test how alternative choices flow through to bills and returns.

Advisers and expert witnesses

Ground submissions and testimony in reproducible, methodology-faithful analysis.
