Data sources & attribution
Every figure on InfraValue traces back to a public record. Each source below is pulled automatically on a maintained schedule, cleaned, and linked to the asset it belongs to — no hand-keyed data where a feed exists. This page is our standing attribution under the Open Government Licence.

Use & limitations
InfraValue is a screening tool — not investment, legal, or financial advice. Public registers contain errors, lags, and gaps, and entity-to-asset matching is probabilistic in places. Verify any data point against its primary source before relying on it.
The full method — how sources are cross-referenced, the signal taxonomy, and the subsidy-cliff calculation — is on the methodology page.
