A friend has had a review of his fixed term morgage and is now going with a new lender. His solicitor is charging for a new set of searches, registration fees etc as if it is a house purchase. surely this isn't necessary is it?
Not all searches need to be repeated: only one to check that you're not bankrupt and that there are no other debts secured on property. Local authority search not needed (or, if it is, it can be replaced by insurance).
New mortgage (and discharge of old mortgage) will need registration at HM Land REgistry, but fee is much lower than for purchase.
