LL19
6,700 domestic properties carry a LL19 postcode. Postcode districts don't line up with council boundaries — LL19 spans Denbighshire and Flintshire, and this page counts all of them honestly rather than filing it under one authority.

Distance from standard
64.1→81.3
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.

Flood, heritage & conservation
Constraints on the ground
Three separate checks, kept separate on purpose — a property can sit in more than one at once. Denbighshire and the other authorities here have different profiles — the figures below are this district's blended total across all of them, not any single authority's own number.

6,700properties 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.
11.8%households in fuel poverty (WHCS 2017-18 estimate)
9%of homes are social rented (Census 2021)
This is Denbighshire's own local-authority figure, inherited — the source data (2017-18) has no finer grain than a whole council area, so every property in Denbighshire reads the same number.
This is the aggregate picture. Every property behind it has its own record.
Certificate history, exact flood zone, planning constraints, deprivation and tenure — matched to the UPRN and searchable one property at a time inside CrierData.
