You can cancel anytime you like, tho obviously you have to be covered by someone. If you are paying by monthly direct debit it will probably be easier, tho you may be faced with an admin charge - ditto if you have paid in one go.
That said, any savings that seem to be there, may not be. If I were you I would try talking to them to see if they can explain why you can appaently get it cheaper elsewhere and who knows, they might offer you a better deal.
