Source project UKS006: Hayes Bridge and Heathrow Interchange, London. Hayes Bridge/Heathrow area in west London; not Hayes in Bromley. Locality representative point only; no site coordinate inferred.
Map points are not surveyed parcel boundaries or electricity connection nodes. The stage is a source-based interpretation at the evidence cutoff, not a current-status check.
