Our Data Philosophy
PropTerminal is built on verified data and full transparency. Each pillar below has its own page explaining what we do, how we source and classify data, and the goals behind it.
Trust Legend
What our data colours mean
Every metric across PropTerminal carries a provenance tag using this exact colour system, so you always know whether a number is a verified fact, a derived calculation, or an AI estimate.
Sourced directly from official authorities — HM Land Registry, ONS, Police.uk, EPC, URA, DLD. Treated as fact.
Calculated by our models from verified anchors — e.g. a yield derived from a verified price and verified rent.
An AI estimate built from nearby verified data. Clearly flagged and never presented as a confirmed market fact.
No verifiable source exists. We show this honestly rather than inventing a number.
