Hi
Yes they have offered us that but it would mean that i would have 2 mortgages running simultaneously (or however you spell it) and when each came up to be renewed in the same year i'd get stung with product fees twice (last time it was £599) just to go on another fixed rate.
Its not ideal this - they seem to get you at all angles :-)
Still all is not lost cause i have found a good rate with the Halifax so that might be a goer....
Thanks for your help though
