WWL says

John Brennan is “a very good advocate” in professional negligence disputes, and represents claimants pursuing claims against accountants, architects and financial advisors.


John Brennan is an experienced junior counsel at St Philips Chambers in Birmingham.

John regularly acts for claimants seeking to prosecute professional negligence claims against solicitors, surveyors and valuers. He also acts in cases against other professionals such as accountants, architects, barristers, consulting engineers and financial advisors. He also accepts instructions from professionals facing allegations of professional negligence including, in particular, solicitors.”

He has been instructed to appear in professional liability cases at all levels from the County Court to the Supreme Court.

John’s recent work includes a claim brought by a Property and Affairs Deputy against his predecessor arising from the latter’s negligent failure to invest a substantial award of damages following the conclusion of a claim for catastrophic personal injuries; and the defence of an execution-only stock broker against allegations brought against it by the victims of a dishonest financial advisor.

In the most recent edition of Chambers and Partners (2021), the editors describe John as a “Standout junior” who is “especially strong at handling professional negligence claims brought against solicitors.  He is also frequently instructed in claims against engineers and property professionals.”
