Leakage allowance schemes are set by the wholesaler, but a school's account is with its retailer. Ask your retailer which wholesaler scheme applies, what evidence it needs, and what the repair deadline is, before you commission the repair.

In Devon. A site of this size has a distribution network rather than a single supply run, which changes how a leak is isolated.

The twelve regions arranged as a tile grid, shaded by open school count. the South West is outlined. Counts come from the four national school registers, not from an estimate.
What this means for a survey in the South West
The ground and water conditions above are the practical part. Hard water scales fittings and shortens the life of valves and mixers. Soft water is easier on scaling but less forgiving of some older metallic pipework. Shrinkable clay moves through a dry summer and pulls buried joints apart, and former coalfield ground settles differentially for decades after the workings closed.
None of that changes the sequence: measure at the meter, isolate to a branch, locate from the surface. It changes what we expect to find and where we look first.
Case studies from schools in the South West
None published yet. Rather than write a plausible-sounding example, this page says so. When ADI supplies a school in this region that is happy to be named, or happy to be described anonymously, it will appear here with the measured loss and what the repair involved.
