Managing your London Stock Exchange Membership

Updating Your Profile

A member firm’s profile encompasses the firm’s trading access to the Exchange’s markets, the firm’s trading codes and related clearing and settlement arrangements for the firm’s business. Member firm profiles are communicated to other member firms and interested parties via Member Firm Information Sheets available to view on the Exchange’s website.

A list of frequently asked questions relating to member firm profile changes is available here but if you are unclear on anything or wish to discuss this further, please contact the Membership Team via email at or via telephone on +44 (0)20 7797 1900.
