Notting Hill Surveyors provides independent expert witness services for courts, tribunals and formal dispute resolution across London. As an RICS chartered practice, we prepare evidence that meets the standards the civil justice system demands: impartial, reasoned and fully compliant with Part 35 of the Civil Procedure Rules. Every expert witness surveyor we put forward understands that their overriding duty is to the court, not to the party who instructs or pays them. That duty shapes everything we produce, from the first advice on the merits of a claim to the final report and any oral evidence given at hearing. Whether you need a building expert witness for a construction defect claim or a valuation specialist for a dispute over property worth, we deliver clear, defensible opinion evidence that stands up to scrutiny under cross-examination.
Property litigation frequently turns on technical questions that only a qualified surveyor can answer with authority. You may need an expert witness surveyor when building defects are alleged and their cause, extent or cost of repair is contested; when a professional negligence claim is brought against a surveyor or valuer and the standard of their work must be assessed; or when parties disagree over the value of a property in a sale, lease or matrimonial dispute. Dilapidations claims at the end of commercial leases, party wall disputes between neighbouring owners, boundary disagreements and housing disrepair claims by tenants all commonly call for independent expert evidence. In each case, the court expects an objective opinion grounded in inspection, evidence and recognised professional standards, which is precisely what our reports provide.
We act as expert witnesses across the full range of property and construction disputes. Our core specialisms include:
Each specialism is led by a chartered surveyor with direct practical experience in that field.
Expert evidence in civil proceedings in England and Wales is governed by Part 35 of the Civil Procedure Rules, its Practice Direction and the guidance for the instruction of experts. A compliant report must set out the expert’s qualifications, the instructions received, the facts and assumptions relied upon, the range of professional opinion where relevant, and the reasoning behind each conclusion. It must carry a statement of truth and the expert’s declaration confirming that they understand and have complied with their duty to the court. We prepare reports to this standard as a matter of course, and we regularly accept appointment as a single joint expert where both parties agree to instruct one surveyor. We also participate in experts’ meetings and prepare joint statements narrowing the issues in dispute.
Most of our expert witness instructions come from solicitors acting in property and construction litigation, who need a construction expert witness or valuation specialist whose evidence will carry weight with the court. We also act for insurers handling defect and negligence claims, for landlords and tenants in dilapidations and disrepair disputes, and for private clients involved in boundary, party wall and neighbour disputes. Where the parties prefer a proportionate approach, we accept joint instructions, acting as a single joint expert answerable to both sides equally. Whoever instructs us, the substance of our opinion does not change: our conclusions are those we would reach whichever party had appointed us, and we say so plainly in every report. That independence is what makes the evidence useful.
Instructing an expert witness surveyor with us follows a clear sequence. We begin with a conflict of interest check to confirm we can act, then agree the scope of the instruction and the fee basis in writing before any work starts. We review the pleadings, correspondence, drawings and other documents relevant to the issues, and carry out a site inspection where the dispute concerns the physical condition of a property. We then prepare a CPR Part 35 compliant report addressing the questions we have been asked. After the report is served, we respond to written questions from the parties and provide clarifications where needed. If the matter proceeds to trial or arbitration, we attend to give oral evidence and assist the tribunal in understanding the technical issues.
Choosing the right expert can shape the course of a dispute. Notting Hill Surveyors is an RICS chartered practice with detailed knowledge of London property, from period terraces and mansion blocks to modern commercial buildings, and we provide expert witness services across the capital and the surrounding areas. Our reports are written in plain English so that judges, solicitors and lay clients can follow the reasoning without a glossary, while remaining rigorous enough to withstand challenge from opposing experts. We are candid about the strengths and weaknesses of a case from the outset, which helps parties settle where settlement is sensible.
