Carucate reference

Property-market data glossary

Plain-English definitions for the terms used across Carucate. They explain aggregate market evidence; they do not turn it into an individual-property valuation.

Aggregate area
A geography summarised as a group, such as a postcode district, town/city, local authority, region, England or Wales. It is not an individual property or address.
Data currency
The latest eligible market period included in a figure. It is different from the date a page or Brief was generated.
Eligible sale
A standard residential recorded sale that passes Carucate’s price, geography and data-quality rules. It is not an asking price or a valuation.
EPC linkage coverage
The share of eligible recent sales that can be confidently linked to a recorded EPC floor area. It is a coverage measure, not a claim that every local property has an EPC.
Floor-area consistency
Aggregate evidence from repeat EPC records showing how closely recorded floor areas agree for the same dwelling. It describes recorded-data consistency, not physical measurement accuracy.
Median price
The middle eligible recorded sale price in a group. Half of the included sales are above it and half are below it.
Median £/m²
The median sale price per recorded square metre for eligible sales with sufficient confident EPC floor-area linkage. It is withheld where the evidence gate does not pass.
Null, unavailable or withheld
Not zero. A figure may be unavailable because the source does not support that geography, or withheld because the aggregate does not meet its publication gate.
Published area
An aggregate geography that currently meets Carucate’s publication criteria. This is the only geography available through public pages and the Professional API.
Recorded sale
A transaction recorded in HM Land Registry Price Paid Data. It is not a live listing, completed valuation, property appraisal or comparable-sales schedule.
Rolling 3- or 12-month median
The median of all eligible sales in the exact preceding three- or twelve-month window for that period. It is not an average of monthly medians.
Trailing 24 months
The most recent two-year window ending at the stated data currency. Carucate uses this for current market headlines and market-structure measures.
Property-type publication gate
The separate evidence threshold applied to detached, semi-detached, terraced and flat/maisonette slices. A district can be published while a thin property-type slice remains withheld.
Flood-screening context
An aggregate count based on postcode centroids and published flood zones where available. It is not a property flood-risk result, insurance assessment or statement that risk is absent.
