Use your current/cash accounts regularly, ask for overdraft, go into negative and repay it on time.

Ask for credit cards, use them regularly and repay them on time.

Just transfer between multiple accounts, pay your bills and credit cards on time, increase the overdraft every once in a while....

Also: I will Teach You to be Rich is a great book. It has an entire chapter for helping you improve credit. I suggest you read it for a good base.
