How the estimate is made

Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 2 sales are recorded for 30 Queen Street. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 30 Queen Street. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.

Crime is police-recorded street-level data over the last 13 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF15 7NL.
Council tax band
