Siân has considerable experience of claims involving professionals of all types. With her professional and scientific background, Siân relishes cases which involve scientific aspects or technical issues, and this has led to a strong practice in the Technology & Construction Court with instructions from a wide range of construction professionals including: architects, structural engineers, civil engineers, building surveyors, approved inspectors, Employer’s Agents and project managers.

Siân has become known for adopting a commercial and problem-solving ‘can do’ approach which has led to instructions on complex cases from employers, contractors and sub-contractors, as well as insurers and professionals.  Her ‘pure construction’ work complements her continuing construction and property professionals’ practice.

Siân has particularly developed a practice involving claims arising from design and construction of unusual buildings, and farm or agricultural buildings, where the combination of her veterinary background and her experience in construction claims as well as professional liability claims has given her clients a considerable advantage.

Siân was instructed on a number of high value claims against major firms of valuers involving commercial properties packaged as ‘tax efficient’ investments in Germany, Denmark and the UK via securitisation transactions (‘commercial mortgage backed securities’ CMBS). These cases involved complex valuations using yields and estimates of income for hotels (K/S Lincoln et al v CBRE Richard Ellis); factory outlet centres (Capita Alternative Fund Services & Matrix Securities v Drivers Jonas); a large multi-use warehouse and department store in Germany (Titan Europe 2006-3 Plc v Colliers International UK Plc); a group of commercial buildings in London (Whitetower 2006-3 Plc v Colliers International UK Plc); a group of four substantial office buildings near the Tower of London (LRC Holdings v BNP Paribas).

Siân is regularly instructed on behalf of barristers and solicitors being sued by former clients who value her thorough and quick forensic analysis, followed by clear strategies to bring the claims to an early resolution.

Siân has wide experience of group action claims against solicitors who acted on ‘right to buy’ schemes and developments where clients ‘bought’ leasehold interests in individual units (e.g. rooms in student accommodation, care home suites, hotels rooms, ‘off plan’ holiday properties) both in the UK and abroad.

Siân has wide ranging experience of acting on claims for and against accounting professionals for various failures to advise on appropriate tax & VAT strategies (e.g. film partnerships, VAT schemes, Research & Development allowances).

Siân has experience of claims involving land agents, estate agents, and claims under the Trusts of Land and Appointment of Trustees Act 1996.

Siân particularly enjoys cases in new fields and jurisdictions, and cases in all areas of her practice which involve working alongside solicitors, and other professionals, as part of an interchangeable team, dealing with vast amounts of documentation, e-disclosure, or claims involving large numbers of sub-claims and group actions.  Siân is very familiar with cases involving use of electronic databases and e-documents, rather than conventional paper documents.

“An insightful silk who is quickly able to master technical details, and is utterly tenacious in fighting for her client. If you want someone to get the best for a client backed into a corner, she would be a marvellous choice of advocate.” – Legal 500, 2022

“Well organised, with a good understanding of clinical issues in cases.” – Legal 500, 2019

Siân has a significant practice in defending professionals before professional disciplinary bodies, including ARB, RIBA, ACCA, ICAEW, RICS. Sian is a former member of the Disciplinary Panel for the Council of the Inns of Court which is concerned with barristers’ conduct and service issues, and was also part of a working party advising the RCVS and drafted the RCVS’ current guidance on the roles of expert witnesses.  Siân is also a member of the Ethical Conduct Body of the Society of Antiquities.

“Siân is a highly persuasive advocate with a keen intellect and a remarkable eye to detail.
