Operating online since 2002 we now run 4 online marketplaces covering 12 verticals within our Art & Antiques and Industrial & Commercial divisions.

We are bringing our bidders 13,000 auctions a year within an infrastructure that allows secure transactions, easy bidding and comprehensive searching to ensure no opportunity is ever missed.

In doing so, we support our network of more than 1350 certified auctioneers who vet the quality, estimate the value and ensure professional handling of each item.

Hosting over 5,000 auctions a year, listing 3.5m lots the-saleroom.com holds anything from kitchen tables to Dodo skeletons, Picassos to antiquities, autographs to Diana’s dresses, ‘mantiques’ to teddy bears or classic car or coins.

We cater to anyone, from casual private buyers, to luxury designers or professional art buyers, dedicated collectors or high-end dealers. So whether you’re looking to spend £100 on an out of the ordinary gift or commit considerably more on an exquisite Corbusier coffee table, the-saleroom.com will help you browse, find, bid, win and transport your item.
