Just popping in as was checking emails - off to see Mr Grey later
Darren are you a qualified financial adviser? Really little requirement here for someone whio just does mortgages, although there are a couple of just mortgage advisory firms. Also these types of position is usually commission only, or has just a small salary with reliance on commission.
As GA says some of the banks have mortgage departments but this is just dealing with their inhouse schemes.
Let me know a little more - by PM if you wish.
FWIW, I am an IFA with over 15years experience (AFPC, AIFP etc) and am authorised in both the UK and UAE.
