2 year deals are really pointless – that time passes very quickly and before you know it you’ve got the hassle (and potentially expense) of remortgaging.
If you’re going to fix then look at 5 years or longer but, unless you’re at the limits of what you can afford, I reckon you’re much better off with a tracker. They also tend to have no exit penalties so if rates do look like they’re going to rise it shouldn’t be too hard to change to a fix then.
That said, tracker rates seem to have gone up quite a bit lately – my last remortgage was at 1.99 over base about 2 years ago but I’ve just added to my borrowing and the new element (same lender, still good LTV) is 3% over base.
