Mortgage advice - should I go for a 2, 3 or 5 year fixed rate?

[Rocket Man]

I'm about to come to the end of a 5 year fixed term deal. I've been offered another 5 year fixed rate that is 1% lower than the current market rates.

Does a 5 year fixed rate make sense in the current economic climate or would it be wiser to take out a shorter deal (at a higher rate)?

Thanks in advance.
