Asbestos survey Coventry: what should I expect for a 1970s building?

We've just bought a small commercial unit near Coventry that was built in the 1970s, and our solicitor mentioned we should arrange an asbestos survey Coventry based before any refurbishment work starts. I understand there are different types, such as management surveys and refurbishment/demolition surveys, but I'm not sure which one we need if we're only removing a partition wall and replacing the ceiling. How disruptive is the process, and does the building need to be empty? Also, how long do labs take to return results, and what happens if asbestos-containing materials are found? Would love to hear from anyone who has been through this, particularly on timelines and what to ask a surveyor before hiring.
