We have just gone through a mortgage application through Nat West International but we also looked at others... we needed an offshor mortgage as we are not resident in the UK. Rates are pretty good, just a little higher than UK mainland. HTH

Most of the UK daily papers have a money section that will give you up to date info on the best rate mortgages - have a search around and you'll come up with the best one for your needs:

I would certainly not get a mortgage in Dubai for a Uk property. Hopefully they should be bringing interest rates down by 2012 and keep them at fixed rates rather then changing them if and when they want like it is now.
Or do you mean getting a mortgage in the Uk?
