If a survey or valuation missed a serious defect and left you out of pocket, you may have a claim in professional negligence. Kingston Surveyors arranges an independent RICS expert witness to review the original report, assess whether the surveyor fell below the standard expected of a reasonably competent professional, and quantify your loss. We act for claimants and defendants across London, Birmingham, Manchester and nationwide, producing CPR Part 35-compliant evidence your solicitor can build a case on.
A professional negligence claim arises when a chartered surveyor or valuer breaches their duty of care and that breach causes financial loss, for example by overlooking structural movement, damp or Japanese knotweed, or by over-valuing a property. To succeed, you must show both a breach of the professional standard and a measurable loss flowing from it, which is precisely what an expert witness report sets out to establish.
Our RICS expert reviews the disputed survey or valuation against the guidance and standards that applied at the time, gives an impartial opinion on whether it was negligent, and works with a valuer where needed to calculate the difference between the reported and true position. The report is written to Part 35 standards so it can be relied on in negotiation, mediation or court proceedings.
We match your instruction to an experienced surveyor or valuer who understands both the technical subject matter and the litigation process, and who can defend their opinion under cross-examination. Whether you are pursuing or defending a claim, we deliver clear, evidenced reports to your deadline.

Claims against surveyors succeed or fail on one question: did the original surveyor fall below the standard of a reasonably competent member of the profession? The independent experts we arrange answer it by re-inspecting the property, reconstructing what was visible at the original inspection date, and applying the professional standards in force at the time – RICS guidance, survey level scope and current case law principles.
We arrange experts for both claimant and defendant instructions, including missed defects (damp, subsidence, roof failures), overvaluation claims and scope-of-service disputes. Every report is CPR Part 35-compliant with the expert’s overriding duty to the court.
