When credit companies access your score they look not only at what you've previously done but what you've been doing recently and are doing now. Taking out a loan, as PatTheRat said is one way of doing it (assuming you can get a loan) but you could also apply for the Capital One credit card. They offer cards to anybody with a UK address and who hasn't been declared bankrupt albeit with an astronomical interest rate (29.9% I believe). Now, this isn't a card you'd want to use for credit because of the interest rate but if you spend X amount each month on the card and then pay it off on time when the statement arrives, it will help your credit rating. Just don't be tempted to let that X amount be more than you would normally spend and can definitely pay off or you'll probably be doing yourself more harm than good. Good luck.
