The problem in one number

£2 bn of risk is on the table.

Yorkshire Water asked for £11 bn of AMP8 capital. Ofwat allowed £8.3 bn. The difference is risk we will carry into the next five years — risk that needs to be named, mapped to assets and systems, and actively mitigated.

This demonstrator shows how a graph-based digital twin turns 65,000 alarms, EDM events and CIM signals into a handful of decisions that protect compliance, the environment, and the £40 M redress commitment.
