Why teams switch
Plans run from £25 for 2,000 credits to £1,150 for 500,000. Every plan can call every endpoint.
Valuations, sold prices, EPC, council tax, titles, planning, flood and ground risk, crime, schools and demographics, all keyed to the same UPRN.
Watch a UPRN and receive a signed webhook when something changes, so you do not have to poll.
A hosted MCP server and ChatGPT Actions are included on every plan and bill from the same credits.
A fair comparison
PropertyData is the better fit if you need asking prices and rents from live listings, HMO room rents, development appraisal endpoints, or their investor web app alongside the API.
