We speak to David Deacon, a chartered surveyor who has spent his career in residential property. He founded Housing Disrepair Surveys, leading a team of Expert Witnesses operating nationwide in housing disrepair claims. Here, he tells us how the business came about, why impartiality is everything, and what advice he would give to any surveyor considering Expert Witness work.

The importance of this case is that it confirms that medical practitioners providing evidence as to a patient’s fitness to participate in legal proceedings are providing expert evidence. It may be termed ‘professional’ evidence but it is expert evidence. It is expert evidence because the medical practitioner is assisting the court as to matters outside the knowledge and experience of the court. In this case the court depended on the applicant’s general practitioner to understand complex PTSD, spiking of blood pressure to dangerous levels and dysphonia and how they made the applicant unfit to participate in her appeal against the order made by the court as to the disposal of her son’s ashes.

The claimant was diagnosed in 2023 with mesothelioma, after attending his general practitioner complaining of shortness of breath. Initially, the treating hospital considered he was suffering from lung cancer but later, after further consideration, they revised their diagnosis to mesothelioma. The court found that when the expert for the claimant suggested molecular testing, he was seeking to explore the possibilities of resolving the diagnosis, while the court was troubled by the defedant's expert's view that it was not necessary to go on to consider molecular testing when the results of the immunohistology were available.

The case of Maina Kumari Rai v Advantage Insurance Company Limited (T/A Hastings Insurance) [2026] EWHC 784 (KB) provides a good reminder that previous criticism can be brought up to discredit your expert evidence.

The outcome of an Expert Determination is final and binding. However, there are circumstances in which the outcome can be appealed. The case of GSY Hospitality Limited v Gladstone Court Developments Limited Neutral Citation Number[2025] EWHC 3231 (TCC) sets out these circumstances.
