Practice Areas

Siân Mirchandani QC has established a broad commercial practice encompassing construction/engineering, professional liability claims, insurance and disciplinary claims in court proceedings, arbitrations and adjudications. Siân has a particular interest in disputes involving construction, IT, technical and scientific elements and this has led to a strong construction/engineering practice and wide ranging experience in regulatory and experimental product testing claims. Siân is also a TECBAR accredited adjudicator.

Prior to her successful first application for silk in 2018, Siân was recognised as a Leading Junior by the directories for Construction, Professional Negligence and Disciplinary, and was the winner of the Chambers & Partners - Professional Negligence Junior of the Year 2016. Siân has a phenomenal work ethic and a very commercial approach to her cases which has led to her being highly sought after. Her wide-ranging practice covers all aspects of commercial work including professional liability, construction, insurance, reinsurance, regulatory and property damage, and includes coverage and indemnity disputes, insolvency, fraud, dishonesty and disciplinary & regulatory matters.

Siân has wide and considerable experience of professional liability claims, including claims against accountants, tax advisers and auditors, architects, building inspectors, engineers, financial services professionals, insolvency practitioners, insurance brokers and agents, lawyers (solicitors and barristers), surveyors and valuers (including claims by issuers of derivative products such as loan notes or unit trusts backed by high value property portfolios), administrative receivers, land management agents, farm management agents, estate agents and veterinary surgeons.

Siân also has considerable experience of professional disciplinary tribunals (particularly architects and building inspectors), arbitrations, adjudications and mediations.


Having qualified from Cambridge University as a veterinary surgeon in 1992, Siân worked in academic and general practice as a veterinary surgeon before coming to the Bar and joining Chambers in 1998, taking silk in 2019.
