In 2018, Tandem Money acquired Harrods Bank and renamed it as Tandem Bank, to operate under its existing licence. This allowed the business to continue trading


Revolut was founded in 2015 and started as a prepaid travel card offering low-cost exchange rates. Currently, Revolut has over 5 million customers worldwide and has yet to obtain a banking license here in the UK. Revolut is not protected by the Financial Services Compensation Scheme.


Monese was founded in 2015 and provides banking services on mobile only. Monese is registered with the FCA but does not have a banking license.


nimbl is a prepaid card that comes with an intuitive app and a series of useful features for parents and children. It isn’t a bank and doesn’t offer a regular current account.

It allows parents to put money on the children’s card, either occasionally or by setting up regular payments. Children can then use it as they wish, be it buying ice creams every week or saving for an expensive video game console.

The idea is to promote good money habits for 8- to 18-year-olds, training children to save, budget and be organised with their money.


NatWest has launched an app-only bank account named Bó, offering built-in budgeting features and an eye-catching yellow card – but how does it compare with more-established digital rivals Monzo and Starling?

Bó is a free account which can provide instant transaction alerts, a ‘piggybank’ for setting cash aside from your main balance and detailed spending reports.

However, while these features may not measure up to Monzo and Starling’s, Bó will appeal to travellers, as it has no fees for overseas spending and cash withdrawals.


Cashplus offers a digital-only personal current account, with all the services available through an app on your smartphone or directly online.

With Cashplus, you get all the standard features of a current account: a card, bank payments, ATM withdrawals, direct debits, an overdraft option and so on.

However, Cashplus’ main focus is helping people to improve their credit score, so it offers a “credit builder” feature that’s what really distinguishes it from other providers.

If you activate it, Cashplus “lends” you your monthly current account fee, and then treats your monthly payments as loan repayments, which are then reported to the credit reference agencies. If you keep up with the payments, your credit score will improve.
