“She brings great attention to detail and a very user-friendly and commercial approach.”
The Legal 500 2015

Jess Connors specialises in commercial disputes. She has advised and appeared in complex and high value arbitrations – both international (including LCIA and ICC) and domestic – as well as litigation in the English Commercial Court, Mercantile Court, TCC and Court of Appeal, and mediations.

Jess is an experienced advocate. She has extensive experience of disputes arising out of shareholder and joint venture agreements, agency agreements, international and domestic supply contracts, oil & gas development projects, offshore construction, waste disposal, as well as hydroelectric and conventional power generation facilities and power transmission systems.

In addition to her extensive experience of performance bonds and guarantees, Jess has acted for and against insurers and reinsurers in disputes arising out of policies insuring against property damage, business interruption, credit default, professional indemnity, public liability and other liability. She also has experience of disputes arising out of factoring agreements. Chambers & Partners 2014 said “She rolls up her sleeves and gets stuck in”.

Jess has a finance background. Before coming to the Bar, she was an equity analyst with Credit Suisse First Boston and Citigroup in Paris and London, covering mid-cap engineering and aerospace companies. She later spent 7 months on secondment to the Financial Services Authority, as it then was, where she advised in relation to various matters, with a particular focus on insurance and investor compensation.

In the construction sphere, Jess has been instructed to advise and represent contractors, employers, developers, construction professionals and insurers, as sole counsel and as a member of a larger counsel team, in domestic and international disputes arising out of projects on JCT, NEC, FIDIC and bespoke contracts, and in professional negligence disputes, both construction and non-construction related.

In 2009, Jess participated in the international stage programme of the École de formation professionelle des Barreaux de la Cour d’Appel de Paris (EFB).
