Analysis of the water industry’s annual water resources performance
The Environment Agency’s annual review of water demand and supply across the wholesale water companies in England: leakage per capita, leakage as a share of distribution input, distribution input per capita, per-capita consumption and the household and non-household split, reported per company.

Notes
Collected, and its limits are worth stating precisely because they decide what can be built on it. Each edition carries six per-company indicators for a single regulatory year — leakage per capita, leakage as a share of distribution input, distribution input per capita, per-capita consumption, and household and non-household meter penetration — for eighteen companies. Only two editions exist, covering 2023-24 and 2024-25, so this route yields six English utility indicators over two years, not the long series the blocked Ofwat dataset holds. A five-year table also appears in each edition but is national rather than per company. That matters: the composite utility index needs three indicators over five common years at utility level, and two years does not reach it — so this source improves utility depth without triggering an index, which is the honest outcome rather than a reason to lower the threshold. Figures use regulatory years running April to March and the company-reported water balance, so they are not comparable with international non-revenue water percentages or with the French linear leakage index Hydrionis already holds; definitions have also been restated between editions, which needs checking per metric before any series is published.
What Hydrionis holds from this publisher
The publisher’s own coverage is above. This is what Hydrionis has actually taken from it, at the subjects it measures — gauges, boreholes, reservoirs or places.
What is measured
- Distribution input per person · l/person/day
- Household metering · %

- Leakage per person · l/person/day
- Leakage per property · l/property/day
- Non-household metering · %
How current it is
- Expected publication lag
- Hydrionis holds everything EA water resources currently offers — it was read 4 days ago. The newest value still covers 2024, further back than the 550 days an annual value usually takes to appear. The publisher has not issued anything newer; the gap is its reporting schedule, not a Hydrionis failure.
