On the other hand though (at least in my experience in the UK) there are still retailers such as airlines/hotels/transport companies that will penalise you for using a credit card.

I've even seen in small shops signs that say they only accept debit cards.

On the other hand most UK current accounts at the moment are giving decent rates on balances (my bank gives me 3% on balances between £3000-£20,000 as well as direct debit cashback on bills and utilities).
