To talk to me is free but I do charge for my advice if you want me to submit an application to a lender. Typically this will be 1% of the mortgage amount payable in two parts - £295 to get you an agreement in principle from a lender. This means they are prepared to lend having carried out a credit search & score. The second part payable by your solicitor on completion.
Any decision to transact business is made by you on the basis of your own enquiries. To check that an adviser is regulated, you can contact the relevant regulatory or professional body.
