The best place for painting auctions, and the best price!..as they have the collectors eye..is Christies International. They have two London locations to work with. Here is a link to their contact information. http://www.christies.com/about/locations/
Bonham and Brooks which is part of Bonham's, a larger international auction house has two locations. Another fine option in town is Phillips who has a long history of auction sales:
