Are you thinking of switching to an online bank?

The United Kingdom (U.K.) banking industry may still be dominated by the "big four" banks (Barclays, HSBC, Lloyds Banking Group, and the Royal Bank of Scotland/NatWest), however, digital banks with their innovative technology and consumer-driven approach to banking are starting to make their mark in the financial services industry and have begun to disrupt the big bank monopoly.

Many of the digital banks are headquartered in the UK and you have many options to choose from if you are looking for a different banking experience.

We have listed the top 5 online banks in the U.K. in this blog. Before we get to the list, we shall discuss what digital banks are and whether they are safe or not.

What Are Digital Banks?

As the name suggests, these banks known by different names like online banks, digital-only banks, mobile banks, app-based banks, neobanks, or challenger banks exist only in digital form-they don't have an established physical location aka brick-and-mortar branches, like the traditional banks.

They are usually app-based, hence are easily accessible on your smartphone. Traditional banks do offer online banking and mobile banking but digital-only banks exist entirely on digital platforms.

Banking services and products ranging from current/savings accounts to investment in mutual funds, stock trading or trading in cryptocurrencies are all accessible through your hand-held devices, eliminating the need to visit a bank branch. Digital banking is the digitization of every level of banking, from front to back-end.

Digital banking has grown massively in recent years, thanks to the advancements in financial technology or fintech and the increasing demands of tech-savvy consumers for efficient ways of banking. According to UK-based research firm Juniper Research, the digital banking users in the world will exceed 3.6 billion by 2024, a 54% increase from 2.4 billion users in 2020.

As per the latest stats, in the UK, 27% of adults have an account with a digital-only bank equating to about 14 million Brits as of January 2021. The number of people with a digital bank account could reach 23 million by 2026.


Should You Switch From A Traditional Bank To An Online Bank? Are They Safe?

Unlike the traditional banks that rely on outdated legacy systems and old ways of doing things, this new breed of banks are more agile, technologically driven, and focus more on user experience which adds a competitive edge.

Additionally, digital banks have low to no interest fees, competitive rates on foreign exchanges, high annual percentage yield (APY), better budgeting features, intuitive banking tools and are generally user friendly.

As mentioned earlier, online banks don't have any physical branches, might have fewer financial products in comparison to traditional banks, and have no face-to-face customer support and advice (instead, you get the customer support via a phone line or a live chat feature in-app).

Most importantly, these app-based banks namely, Starling Bank, Monzo, Atom Bank, are fully licensed and protected by Financial Services Compensation Scheme (FSCS) which means your money (up to 85,000 pounds) is protected in case the bank goes under.

For digital banks not covered by FSCS (do not hold UK banking licenses), such as Revolut and Monese, they are covered by the Financial Conduct Authority (FCA). In other words, if the app-based banks are not backed by the FSCS, then chances are that they are working with one of the traditional banks, and your funds are protected in a licensed bank that your digital bank has partnered with.

Thus, it is important to note that, although the two types of banks are technically seen as "rivals", they do work together alongside each other, bringing superior banking services to customers.

Many people still use traditional banks for savings accounts (because traditional banks tend to have marginally higher interest rates), credit cards, and overdraft facilities among others.

They also make use of the services offered by digital banks to manage their finances such as everyday spending and daily budgeting.

When choosing the best online or digital bank, look at the services that they offer, unique features, and online reviews. The best online banks will depend on your financial needs and goals.
