Over the past few years, Britons have been showered with new financial companies. These financial technology companies and challenger banks want to replace established banks and the old guard. They aim to make financial dealings more convenient, mobile, hassle-free, and cost-efficient. For example, customers can open accounts using smartphone apps instead of visiting branches. Moreover, unlike traditional banks, their products and services are designed to accommodate new types of workers, including freelancers, remote workers, digital nomads, and global citizens.

Three challenger banks that should be on your radar are Revolut, Monzo, and Starling Bank. Wise, a money transfer and financial services company, should also be on your radar. Let’s review and compare their products, services, and plans in this post.

How to Choose a Mobile Banking App/Company

Choosing the best mobile banking app depends on your needs, financial goals, and budget. Understanding those aspects will make selecting the right partner and company easier.

Assess your needs first. Before evaluating financial apps, consider your requirements. For example, you want flight insurance because you travel a lot. Or, you request payments often and want to use a customizable link to make the process more efficient.

Understand your financial goals. For everyday financial transactions, mobile-first banks are excellent. However, suppose you want to start investing or seek a tax-exempt account. Most challenger banks don’t offer robust investing platforms. Moreover, tax-free accounts are rare. Thus, you might have to look around or stick with the status quo to achieve your goals.

Consider your budget. While free accounts/plans are standard with neobanks, users must pay to access more features and benefits. It’s the classic freemium model that thousands of tech companies use. They offer free plans to convert users to premium accounts later. Secondly, monthly plan/subscription fees can add up to over a hundred euros, pounds, or dollars annually. However, paying monthly fees might not be financially prudent or practical for some people’s budget/saving objectives or debt obligations.

Standard Features

Fintechs and neobanks will continue to add products, services, and features to compete with their rivals and traditional banks. What one company doesn’t have today will likely offer in a few months to a year. Therefore, you needn’t worry about missing out on the long term. Challenger bank apps typically have these features:

  • Virtual and physical bank cards
  • Instant push notifications on all transactions
  • Analytics and categorization of expenses
  • Multiple accounts for saving and budgeting goals (not the same as an interest-bearing savings account)
  • No foreign exchange fees when spending abroad
  • Free money transfers to other users
  • Make recurring payments
  • Download and print account activity
  • Connectivity to third-party apps, for example, Apple Pay and Google Pay
  • Card lock/unlock at your discretion. For instance, if your card gets lost or stolen

Products & Services

Current & Multi-Currency Accounts

A current (checking) account is a bank account that allows you to conduct everyday financial activities, such as deposits, withdrawals, bill payments, and recurring payments. A current account typically doesn’t earn interest but may receive it if it maintains a minimum amount set forth by the bank, for example, £25,000.

All four companies offer GBP current accounts. Revolut, Starling Bank, and Wise also have free EUR IBAN accounts.

Savings Account

A savings account is a bank account where you can store money you don’t need immediately but have easy access. It typically earns a modest interest rate.

Monzo, Revolut, and Starling Bank provide in-app saving mechanisms and interest-bearing accounts. Monzo customers can open tax-free savings, joint, and teen accounts. Starling customers can get joint and teen accounts.


Monzo and Starling Bank have overdraft protection, but Revolut doesn’t.

International Money Transfer

Monzo partners with Wise to process money transfers at mid-market rates and low fees. Revolut also converts money at mid-market rates. Revolut customers can send money for free, but fees may apply depending on currencies, amounts, and timing. Revolut is one of two U.K. companies that offer free money transfers. The other is TransferGo. Starling Bank does money transfers, but its rates are not as reasonable as Revolut or Wise.

Revolut offers commission-free stock, commodity, and cryptocurrency trading. Wise allows you to invest in cash, bonds, or stocks with ETFs. Monzo and Starling do not support investment activities.

Monzo, Revolut, and Starling Bank offer insurance products.

Personal Loans

A personal loan is a type of unsecured loan. You typically don’t need to pledge any security or collateral to get the loan. Instead, the lender provides funds to use at your discretion but charges a fixed or variable interest rate on the entire amount of money used.
