Occupation: Chartered Architect, Arbitrator and Expert Witness

Email: will@williambates.co.uk

I am an independent registered architect with RIBA Chartered Practice status. I am also a member of the Chartered Institute of Arbitrators. I have over 25 years experience as an Expert Witness in construction disputes of all kinds. I have particular experience involving claims of professional negligence and disputes concerning professional fees between client and architect. I cover London, Kent, Surrey and Sussex areas in particular, but I have experience elsewhere in England and Wales.

I have been appointed both as a party expert witness and as a single joint expert to evaluate evidence and provide opinion. Most of my instructions are from solicitors (or occasionally, barristers) and I am happy to be instructed at an early stage of a dispute to make an assessment of the issues involved and the chances of success, whether acting on behalf of the claimant or the plaintiff.

I have appeared at both formal and informal hearings and mediations and I have High Court (Technology and Construction Court) experience. I am on the RIBA panel of Architect Expert Witnesses and I am a member of both the Academy of Experts and the Society of Experts. I am listed with the UK Register of Expert Witnesses and in the publication Expert Witness, Expert Consultant. References from solicitors are available on request.

Party Walls

I have extensive experience in party wall negotiations and disputes, particularly in London (where I practiced until 1990), acting both for the developer / private owner and the adjoining owner.


I also have extensive experience in planning negotiations, formulating and presenting planning and Listed Building applications and appeals, including appearing at both formal and informal hearings.
