What can I do for you?

I specialise in professional negligence claims and have done so for 25 years. I have dealt with claims against most professionals including some of the newer professions. For the last 20 years I have dealt exclusively with claims against construction professionals, including surveyors and valuers. I have substantial experience of court proceedings, arbitration proceedings, adjudication and ADR. I am instructed to advise on policy coverage and have been appointed coverage counsel for claims in this country and abroad, including Australia, Canada and Turkmenistan!

A recent highlight includes successfully representing Aspect Contracts in the Supreme Court in a landmark case that considered construction adjudication, limitation, negative declarations and unjust enrichment.

Supporting my clients’ ambitions

I always strive to resolve claims promptly and cost efficiently. Recent examples of this include:

  • Defending a claim against a signature firm of architects in relation to a £5 million loss and expense claim made by the main contractors following the delayed completion of new Museum and Cultural Central.
  • Defending M&E D&B contractors in relation to a claim brought by the freeholders of a prestigious London Development following the failure of the cold water installation which caused £5M value of flood damage.
  • Defending a leading national contractor against a £9 million claim involving allegations of negligence in the design and specification of a one of the largest (warehouse) floor slabs in Europe. 

I am frequently asked to do is advise underwriters on policy drafting and to assist them in their assessment of potential insurance risks, which is something I particularly enjoy.
