Expert Witness Services for Building Defect Claims

A Part 35 expert witness is an independent professional who provides impartial evidence to the court under Civil Procedure Rules Part 35. Unlike other witnesses, experts owe their primary duty to the court—not to the solicitor or client instructing them. Their reports must be objective, evidence-based, and transparent. At Surv-A Consultants, our expert witness evidence is unbiased and backed by independent investigation.

We provide expert witness services for disputes involving structural waterproofing failures, damp and moisture ingress, ground gas protection defects, building pathology issues, construction defects, and non-compliance with BS standards. Our expertise covers both substructure and superstructure failures across residential, commercial, and industrial projects.

We have no commercial relationships with contractors, developers, or product manufacturers. Our conclusions are based solely on site evidence, material testing, and standards analysis. We present all relevant facts—including those that may not support the instructing party's position—because our duty is to the court, not to any commercial interest.

Our service includes forensic site investigation, photographic documentation, material sampling and testing, analysis against relevant British Standards, preparation of a detailed Part 35 compliant report, and attendance at court or expert meetings if required. We also provide clear explanations of technical matters for legal teams and judges.

Yes. Our accredited professionals are experienced in providing oral testimony and can attend court hearings, case management conferences, and joint expert meetings.
