He has also appeared in many of the leading costs cases over the last 20 years, and was chair of the committee that introduced the now mandatory electronic bill of costs.
Alexander has appeared in a substantial proportion of the most important cases, such as Lownds, Factortame, Gloucestershire CC v Evans, Claims Direct, Accident Line, Jenkins v Young Brothers, Henry v Newsgroup, Blankley, Marcus v Medway.
He represented the appellant in Blankley v Central Manchester NHS Trust, a Court of Appeal case concerning whether the loss of a client’s mental capacity frustrates the contract of a retainer.

He deals with the highest value costs cases in the High Court and Court of Appeal and in advising on retainer issues, drafting retainer documents and advising on costs issues during the course of the main litigation as well as on, and on appeal from, detailed assessments.
