Average current efficiency score against average potential score, on the certificate's own SAP scale. The gap is what a certificate's own recommendations are already aimed at closing — a reading of the certificates as issued, not a projection.

10,364properties within roughly 2.2km of a listed building
A proximity signal, not a listed-status check — this counts nearby listed buildings, not properties confirmed to be listed themselves.
Deprivation & fuel poverty
Neighbourhood context, Wales-wide
The Welsh Index of Multiple Deprivation ranks every small area in Wales nationally, from 1 (most deprived) to 10 (least) — not directly comparable to England's own index, which uses different domains and weights.
10.0%households in fuel poverty (WHCS 2017-18 estimate)
13%of homes are social rented (Census 2021)
This is Swansea's own local-authority figure, inherited — the source data (2017-18) has no finer grain than a whole council area, so every property in Swansea reads the same number.
