[2023] UKUT 00282 (LC)

The parties each instructed an expert building surveyor and a structural engineer to provide evidence to us on the condition of the house and the extent to which defects might have been caused by the works.

As will be seen the surveyors were agreed on all material points – neither was called for cross-examination – and there was very little between the structural engineers. Neither pair of experts takes things very far at all in terms of causation – which is to say that the claimants cannot prove their case on the basis of either the surveying or the structural engineering evidence. So we can summarise what they had to say quite briefly, before turning to the evidence of the hydrologists on which the case turns.
