I would opt for either the Woolwich product Ian mentions above.
There are no fees on entrance, but a £275 exit fee.
Or, C & G also have a lifetime tracker with £99 entrance fee and no exit fee. If you are moving so soon, that makes C & G slightly the better deal.
Needless to say, C & G are suffering service wise at the moment too.
There are other things to consider, so i would suggest you see a decent broker and get him to do the work - much easier than doing it yourself. You'll probably find all the forms are completed for you as well, which is the biggest headache.
