112,973 domestic properties in Northumberland are matched to a UPRN in CrierData and checked against six national registers — energy performance, flood zone, heritage constraints, deprivation, and housing tenure. Every figure below is a real count from the current release, not an estimate.
Northumberland's housing stock, read from its current certificates: 49% of properties sit at band D or lower today. That is a starting point, not a verdict — most of that stock also has a documented route to a higher band, tracked property by property inside the full product.
Three separate checks, kept separate on purpose — a property can sit in more than one at once.
The English Indices of Deprivation rank every small area nationally, from 1 (most deprived) to 10 (least). Here's how this area's neighbourhoods sit against the rest of England.
Share of properties whose neighbourhood falls in each national decile. Decile 1 is the most deprived tenth of neighbourhoods in England, decile 10 the least.
