I haven’t bothered. I had a chat with them and said if they can provide me with Building Control data for addresses in Buckinghamshire I would be interested. So far, they only appear to have access to the usual public access data and my local authority doesn’t make this data public. The client will get more from the searches undertaken by their solicitor in my opinion. (BTW I suggested you as a more local surveyor for an ex-colleague of my son’s yesterday, buying near Market Harborough)
