Savills, Allsop and SDL Lead New UK Auction House Performance Index

A new UK Auction House Performance Index has been launched by property data group UncommonDeal, ranking the top auction houses across Britain. The index is designed to help investors, landlords, developers, deal sourcers, and property professionals compare leading auction brands on a like-for-like basis.

The index scores auction houses based on several criteria, including lots sold, success rate, geographic coverage, investor suitability, transparency, and auction frequency. According to the results, Savills achieved the highest score with 100, followed by Allsop with 94, and SDL Property Auctions with 88. Auction House UK scored 86, and Barnard Marcus received 82. Other auction houses in the top ten include Clive Emson, Pattinson, Acuitus, Network Auctions, and Hollis Morgan.

UncommonDeal states that the scores are intended to provide buyers with a practical snapshot of each auction house’s position in the wider market. The company emphasises that the index should be used as a starting point for further due diligence, rather than as a substitute for reviewing individual lots, legal packs, fees, and local market evidence.

The index highlights that there are meaningful differences between auction houses, particularly in areas such as success rates, buyer costs, and the types of opportunities available. For investors, factors such as buyer fees, legal-pack conditions, refurbishment costs, and the realistic resale or rental value are important considerations beyond the headline guide price.

UncommonDeal advises that investors and property professionals should not focus solely on the number of properties offered by an auction house, but should also consider which auction houses consistently provide opportunities that align with their investment strategies. Full due diligence on each individual lot is recommended before bidding.

This new index may be of interest to UK letting agents and inventory clerks seeking to understand the current landscape of property auctions and the performance of leading auction houses.
