Purely Mortgages chief executive Mark Chilton says the main issue on the first day of mortgage regulation has been several lender websites are unavailable.
This means KFIs cannot be accessed on-line and KFIs cannot be validated against the lenders' by cross referencing.
Also, some lenders are taking longer than usual to answer the telephone and deal with enquiries.
Chilton says: “We are very calm. But it seems a lot of lenders are still not prepared.”
