All, thanks very much for your ideas.
Going back to my original query, I think the reason for the 2000' altitude restriction on this occasion was due to a noise abatement restriction. Due being vectored off our normal track, we commenced our visual approach from a rather different position than is normal, and our track took us straight over a large conurbation, hence the unexpected clearance.
