What’s the difference between an auction and a private sale?

At auction, items are bid on and sold to the highest bidder in a public sale. Private sales are for the discreet brokerage of a high-value transaction between seller and buyer


How are estimates determined?

To establish an estimate for your item, Sloane Street Auctions will evaluate your property and market demand according to such important aspects as:

  • Artist or maker
  • Country of origin
  • Provenance
  • Date of execution
  • Materials
  • Dimensions
  • Rarity
  • Subject matter or type
  • Condition
  • Quality


What is a reserve price?

Common to auctions, a reserve price is the minimum amount that a seller will accept as the winning bid. An agreed-upon reserve price for each item of property will be set at or below the low estimate, namely at a level which does not exceed the low estimate. This price is strictly confidential between you and Sloane Street Auctions, and will ensure that your property does not sell below this chosen price


Is my valuation request free of charge?

All our estimates are complimentary. Please kindly note that Sloane Street Auctions only provides estimates for items that have been identified as potentially suitable for sale.


How long does it take to receive an estimate?

Sloane Street Auctions will answer an initial enquiry within five business days. On some occasions, if an item requires additional research, more time will be needed. In such special instances, you will be notified of the status of your submission.


Is my estimate a final appraisal of value?

All estimates are subject to physical examination of the item, as well as changes in the art market. Sloane Street Auctions’ estimates are not formal documents for insurance, taxes, estate valuations or any other external purposes and cannot be used as such


How far in advance of a sale must I submit my item?

If you wish to submit an item into a specific sale, we normally recommend submitting at least 6-8 weeks prior to the sale start date (see auction calendar for indications of upcoming sale categories). Our in house specialists will review your item to advise on the most suitable auction for selling


What Is The Buyer's Premium?

The buyer's premium is a percentage of the final hammer price that the buyer of an object must pay in addition to the hammer price of an object. Our buyer’s premium rates are as follows: 25% of the hammer price up to and including £450,000, 20% on that part of the hammer price from £450,001 up to and including £4,000,000, and 15% of that part of the hammer price from £4,000,001. VAT will be added to the buyer’s premium and is payable by you. In addition to the buyer's premium and hammer price, the buyer is responsible for paying all relevant taxes and shipping costs. Please see Sloane Street Auctions’ Terms and Conditions for further details.
