I'm not particularly clued up on credit cards; although I have them and use them I've always (with one exception) paid up in full when the statement comes through each month. Looking at spending circa £1500 on a single purchase and a 0% purchase credit card seems to be one way to do it; I have the savings but I'd rather leave savings as savings and pay off over several months.
So, looking at moneysupermarket.com there are several cards that offer 0% over fifteen/sixteen months - I'd pay off over half that in all likelihood.
So, where's the catch - how do the they make their money..? When it says 'Representative Example: If you spend £1,200 at a purchase interest rate of 16.9% (variable) your representative APR will be 16.9% (variable).' - is that the interest that kicks in should I fail to repay in the fifteen/sixteen months..?
