26% of the hammer price of amounts in excess of £20,000 up to and including £700,000;
20% of the hammer price of amounts in excess of £700,000 up to and including £4,500,000;
and 13.9% of the hammer price of any amounts in excess of £4,500,000.

For Motor Cars and Motorcycles a 15% Buyer's Premium is payable on the first £500,000 of the final Hammer Price of each Lot, and 12% on any amount by which the Hammer Price exceeds £500,000. VAT at the standard rate is payable on the Premium by all Buyers, unless otherwise stated.

Some lots may be subject to VAT on the Hammer Price. These lots will be clearly marked with the relevant symbol printed beside the lot number in the catalogue.

ALL BIDDERS MUST AGREE THAT THEY HAVE READ AND UNDERSTOOD BONHAMS' CONDITIONS OF SALE AND AGREE TO BE BOUND BY THEM, AND AGREE TO PAY THE BUYER'S PREMIUM AND ANY OTHER CHARGES MENTIONED IN THE NOTICE TO BIDDERS. THIS AFFECTS THE BIDDERS LEGAL RIGHTS.
