Where our data comes from

Every lot and every sold price on AuctionRadar comes from the primary source: the auction houses themselves, via the catalogues and results they publish on their own websites. Nothing is taken from subscription databases, other aggregators, or any paywalled service. This page explains the pipeline so you can judge the data on its method, not our say-so.

Live lots

We track the published catalogues of 50 UK property auction houses, including the national franchise networks, which together list 17,000+ live lots at any time. Collection runs continuously and the site refreshes every Monday, so a lot appearing in a catalogue this week is on AuctionRadar this week, with its guide price, auction date, address and a link back to the auction house it belongs to. Where a catalogue changes mid-cycle (lots withdrawn, guides revised), the next refresh picks it up.

Sold prices

Our results archive holds 192,000+ auction outcomes, 66,000+ of them with a published sold price, and it grows every week. It is built the same way: from the results pages the auction houses publish after each sale, many of which reach back years (the deepest to 2002). Because houses publish results within days of the hammer, these prices typically appear here months before they surface in the Land Registry. Where a house publishes an outcome as unsold or withdrawn, we record that too; a market is more than its successes.

Repeat lots and angles

Addresses are normalised and matched across every catalogue and every result we hold, which is how a lot page can say "previously offered in March 2024, unsold at £180,000". Roughly one in three auction properties has been to auction before, and knowing that changes how you bid. Each lot is also classified from its own catalogue description into the angles investors search by: probate, short lease, needs-refurb, development, tenanted, vacant possession.

The directory

Alongside the property data product, our directory profiles 1,900+ UK auction houses across every category, compiled from public information: the houses' own sites, published fee schedules and public reviews. Directory profiles are descriptive, not commercial; houses do not pay to be listed and cannot pay to be described differently.

What we deliberately do not do

  • No data from paywalled or subscription databases, ever. If we cannot get it from a primary public source, we do not have it.
  • No commercial relationships with auction houses that touch the data: nobody pays for placement, ranking or a kinder description.
  • No sharing of subscriber details with auction houses or anyone else. We sell subscriptions, not contact data.

Accuracy and corrections

Auction catalogues change right up to sale day: lots are withdrawn, guides move, and a guide price is an indication, not a promise (by convention the reserve sits within 10% of it). Always verify against the legal pack and the auction house before bidding. If you spot an error in our data, tell us and we will trace it to the source and fix it.
