Floor area (declared and predicted) in lending decisions.

Floor area (declared and predicted) gives the internal floor area in square metres, declared and modelled kept separate, published modelled with 99.96% coverage across England and 98.82% across Northern Ireland. Where modelled, it remains separate from declared evidence so you can validate it against your own reference records. Attribution and refresh period are in the dictionary.

The sample record returns 145 m2; a returned area well below the norm for the property type is a prompt to look before trusting a value.

01

Value sanity-checks - price per square metre against the local market.

02

Prefill and verification against the applicant declaration.

03

Rebuild-cost and energy context, which both lean on area.

Declared from record evidence; predicted from attributes and imagery-derived measurement, with the two views published separately for evaluation against reference records.

Three questions on this field.

Both, as separate fields. Vision-derived measurement feeds the modelled estimate where the record is absent; the two are never merged into one ambiguous number.

Yes - as a value sanity-check and a verification prompt against the declared area.
