John Greenbourne

Call 1978

"A master of detail and also very good on his feet."
(Legal 500 2016)

John Greenbourne’s main areas of practice are professional negligence (chiefly concerned with insurance services, legal advice, property valuation and construction, education and clinical treatment); insurance and commercial work; serious personal injuries.

Large cases have included: multi-million pound claims by lenders against valuers; a trial lasting several months relating to the contractual arrangements for tendering for designing and building machines to dig the Channel Tunnel; an arbitration between a local authority and contractors in relation to the construction of a waste disposal facility; insurance and related professional negligence claims for several million pounds (in one case potentially over £100 million); high value claims for personal injury, in one of which the client’s claim was settled for a value exceeding £14 million before conversion of part into periodical payments.

John has great experience in a wide range of claims, including severe head and orthopaedic injuries and for defendants to claims for shipping related accidents. Known for his common sense approach and understanding of the overall picture in a case but also for his attention to detail. While always enthusiastic to fight cases if the other side will not settle on sensible terms, he has a keen appreciation of the personal and commercial considerations, which are important to parties.
