What is an online bank or mobile bank?

Unlike their high street counterparts, online banks, or app-only banks, seek to provide you with all your banking needs from the confines of an app. They eliminate the need to visit a physical bank as opening and managing an account can be done quickly and securely from your mobile.

You can still access customer support services through live chat, email or phone. All of the best digital banks are free to sign up with, however, you may encounter fees for premium services and products.

If you open a new bank account, you will be in a position to order your debit card with an account number and a sort code, just as you would in traditional high street banks.

Through mobile banking, you will be able to pay bills, make cash withdrawals, transfer money, and set up direct debits the same way you would with traditional banks.

The increase in popularity of mobile app and challenger banks is primarily a result of the United Kingdom government introducing the reforms to create digital open banking. Digital open banking simply means that your bank must provide you with the opportunity to share your personal financial data like bank statements, regular payments and spending habits with other banks or budgeting apps.

Which online bank is best?

I’ve compared the services and products of more than 60 nationally available banks that operate online in order to provide you with the best digital banks for your circumstances.

Monzo: Best for budgeting / business banking

Monzo Bank

For users looking to save money, Monzo is an excellent challenger bank due to its wide range of savings accounts and favourable interest rates.

Monzo became a fully licenced bank in 2017 and therefore offers accounts with all the trappings of more traditional banks including account numbers and sort codes.

Monzo has features and tools including the ability to set up direct debits, loans, and an overdraft facility. Checking whether you are eligible for a loan won’t affect your credit score and you could be approved to borrow up to £15,000. With Monzo, you get a debit card that is easy to manage from within the app.

A nice new feature at Monzo is the Monzo Flex, which allows you to pay later with a pre-agreed credit limit, allowing to you pay for your purchases in 3 monthly instalments at 0% interest or 6 and 12 instalments at 19% AER.

High street banks vs digital banks

The banking industry in the UK is still ruled by the big four banks, which include HSBC, Lloyds, Barclays, and NatWest/Royal Bank of Scotland. However, UK digital banks are becoming highly competitive in this space. New ways of providing financial products and services as well as innovative technology have allowed them to be recognised in the industry.

While many traditional banks are also trying their best to offer online services, the neo and challenger banks are more able to capitalise on the latest technology. They aren’t impacted by clunky IT systems, years-old traditions and historical ways of offering services. As a result of this, they can easily respond to the unique needs and requirements of their customers. Some of the new features and services that digital banks provide as opposed to their high street counterparts are:

  • Bill splitting
  • Spending reports
  • No withdrawal and payment fees abroad
  • Instant notifications
  • The feature to lock and unlock cards via apps
  • 24/7 support services
  • Future spending projections
  • Spending limits for certain purchases
  • In-app account creation and approval within a few minutes
  • Specific saving pots
  • Robust identity and verification processes
  • Limitations for problem spending like online gambling

Advantages and disadvantages of app-only / mobile banks

All types of banks have advantages and disadvantages, and app-only banks are no different. The best part is that the advantages outweigh the disadvantages.

Advantages of app-only banks

  • Paperwork isn’t required when opening a bank account
  • You can manage everything from the palm of your hand
  • A low exchange rate
  • Low fees on transactions
  • Advanced money management tools and real-time spending notifications
  • Lost or stolen cards can be frozen from within the app

Disadvantages of app-only banks

  • Only a few app-only banks offer unarranged overdrafts or loans
  • Need a smartphone or tablet to use
  • Reliant on mobile data or internet connection
  • Difficult to deposit cheques and cash

Is now the time to switch to an app-only bank?

The rate at which app-based banks have dominated the banking world is a clear indication of people’s enthusiasm for the potential to make finances easier and more accessible. However, this is still a relatively new concept and requires some consideration before you make the switch in its entirety.

Personally, I like to run my app-only bank, in conjunction with my traditional bank, thus ensuring that I can take advantage of all the features on offer such as favourable overseas transactions and advanced money management tools, but my traditional bank is on hand should I need to deposit cash, pay in a cheque, or access some of the advanced banking facilities like overdrafts and loans which are rarely available with a bank account online.

Whilst there have been several significant advancements with app-only banks, there is yet to be one online bank, that offers all the useful features you might require throughout your lifetime.

Online banks FAQs

Are online banks safe?

Yes, online banks are safe, and there is little cause for concern when it comes to the safety of your money when using an online banking service. Online banks are often regulated by a governing body such as the Financial Conduct Authority and many fall under the Financial Services Compensation Scheme which automatically protects your funds up to the value of £85,000.

What do I need to open a UK digital bank account?

Unlike traditional banks, digital banks have completely streamlined their account opening service and often you will be up and running in a matter of minutes. Whilst you won’t require proof of address, most online bank accounts will require you to take a selfie with your ID and provide your personal details. Proof of ID can include the following: Drivers Licence, UK Passport, EU and EEA National Identity Card.
