What Does an Expert Witness Surveyor Do?
An expert witness surveyor gives the court independent, impartial opinion evidence on building and property matters. Unlike an advocate, the expert’s overriding duty is to the court, not the instructing party. Our chartered surveyors prepare written expert reports, answer Part 35 questions, take part in expert discussions and joint statements, and where required give oral evidence at trial or in arbitration and mediation proceedings.
CPR Part 35-Compliant Expert Reports
Every report follows the Civil Procedure Rules and the Practice Direction that accompanies Part 35: a clear summary of instructions, the factual background, site inspection findings, reasoned professional opinion, and the required statement of truth and expert’s declaration. That discipline makes our building surveyor expert witness reports admissible, readable and persuasive – whether for the County Court, the High Court or the First-tier Tribunal.
Property Disputes We Cover
Typical instructions include housing disrepair claims, dilapidations disputes, party wall and boundary disagreements, valuation disputes, construction defects and professional negligence matters. Where a claim turns on the condition of a building, our surveyors can also draw on Level 3 building survey methodology to evidence defects, causation and cost of remedy.
Single Joint Expert or Party-Appointed
We accept instructions as a single joint expert agreed by both parties, or as a party-appointed expert working alongside your legal team. We also provide early, pre-action expert advice – often the fastest way to understand the strength of a claim before proceedings are issued – together with Scott schedules, costed repair schedules and diminution valuations to support settlement negotiations.

Expert Witness Surveyors for Property Disputes and Litigation
When a property dispute reaches solicitors, court or arbitration, the outcome usually turns on the quality of the expert evidence. Our expert witness surveyors provide independent, CPR Part 35-compliant reports and testimony for litigation across London and Essex — covering building defects, valuations, boundaries, party wall matters, dilapidations, housing disrepair and professional negligence. We act on instruction from solicitors, insurers, businesses and private clients, as party-appointed experts or as Single Joint Expert.
What Makes Expert Evidence Admissible
Under Part 35 of the Civil Procedure Rules, an expert’s overriding duty is to the court, not to the party paying the fee. Reports must set out the expert’s qualifications, the instructions received, the facts and assumptions relied on, and a statement of truth in the prescribed form. Evidence that fails these tests can be excluded — or worse, destroy a party’s credibility. Every report we produce is built to this standard from the first draft.

How We Work with Solicitors
We provide an early merits view before formal instruction, agree scope and fee, inspect and report to court deadlines, respond to Part 35 questions, prepare joint statements with the opposing expert, and give oral evidence where required. Our reports are written in plain English that judges and juries can follow — technical rigour presented clearly is what wins cases.
Single Joint Expert Appointments
Courts increasingly direct that one expert be jointly instructed by both parties, particularly in county court and family matters. We accept SJE appointments regularly: both sides receive the same impartial analysis, which frequently unlocks settlement without trial. Where we act for one party, the same independence applies — our opinion is the same whoever instructs us.
Instruct an Expert Witness Surveyor
Early expert input often changes the course of a dispute: it can confirm whether a claim has merit before costs escalate, and evidence preserved promptly — photographs, measurements, contemporaneous condition records — is worth far more than recollections later. Contact us with a summary of the dispute and your timetable, and we will confirm suitability, independence and a fixed fee.

Frequently Asked Questions
A Part 35 expert provides independent opinion evidence to help the court decide technical issues. Their duty is to the court, not the instructing party. Reports must follow a prescribed format with a statement of truth, and the expert can be questioned in writing or cross-examined at trial.
Most instructions are quoted as a fixed fee for the inspection and report, with hourly or daily rates for Part 35 questions, joint statements and court attendance. Fees depend on the dispute’s complexity — we confirm costs before you instruct us, and SJE fees are usually shared between the parties.
A Single Joint Expert is instructed jointly by both parties under a court direction, producing one impartial report both sides rely on. It is the default in many county court and family proceedings because it saves costs and narrows the issues quickly.
Yes. We provide advisory reviews of opposing expert evidence — testing methodology, comparable evidence and compliance with Part 35 — and act as your party’s expert where the court permits separate experts.
Typical instructions run four to eight weeks from instruction to final report, depending on access and the volume of documents. Where court deadlines are tight we can prioritise inspection and agree an accelerated timetable with your solicitor.
