Role
What Ministry of Housing, Communities and Local Government data lets a tool answer
Floor area is the most useful field after the UPRN: it turns a price into a price per square metre, and the valuation model needs it before it produces a number. The rating history is evidence that work happened; the F and G bands are the cohort that cannot legally be let.
