Most people in the UK don't put regular spending on a Credit Card. Nearly everyone will use their Debit Card for day to day spending.

A lot of the traction it has got has been with the 18-30 age bracket who are wanting better budgeting tools than what larger banks have offered.

Are you sure? All the best cashback offers are with credit cards, not debit cards.

Yes. Cashback from credit cards is mainstream in US culture, but not in the UK (maybe some people care about this, but only ~5% of my friends even have a credit card). Probably this difference is because card transaction fees are regulated to reasonable rates.
