Online banking has changed the way people manage their money.

Instead of visiting a branch to check your balance, make a payment or move money abroad, you can now manage many everyday financial tasks directly from your laptop or mobile phone.

But with over 20 authorized online banks and so many digital banking apps available in the UK, choosing the right one can be difficult. While some are designed around everyday banking, others focus on spending abroad, savings, budgeting or international money transfers.

This raises the question: which online bank is the best and which one should you chose?

In this guide, we compare some of the leading online banking apps available to UK users, including Pesa, Revolut, Monzo, Starling and Chase. We look at their key features, fees, international transfer capabilities, security and the type of customer each option may suit best.

What Is an Online Bank?

An online bank is a financial service that allows you to manage your money primarily through the internet or a mobile app rather than relying on physical branches.

Depending on the provider, you may be able to:

• Open an account online
• Check your balance
• Make bank transfers
• Receive money
• Pay bills
• Manage direct debits
• Use a debit card
• Save money
• Track spending
• Exchange currencies
• Send money internationally

Some online banks are digital versions of traditional banking institutions, while others are digital-first financial providers.

The distinction is important because not every app offering banking services operates in exactly the same way. Some providers are banks, while others offer specific financial services through different regulatory structures.

Before opening an account, check what protections and services apply to the specific product you're considering.

‍

How Do Online Banks Work?

Online banks work in much the same way as traditional banks for many everyday activities, but most of your interaction takes place through an app or website.

Instead of visiting a branch, you can generally download an app, provide your personal information, complete identity verification and open an account digitally.

Once your account is active, you can typically manage it from your smartphone.

Many digital banking apps also provide real-time notifications when money enters or leaves your account.

Some providers go further by offering budgeting tools, savings features, foreign currency accounts, international transfers and other services.

The exact features available depend on the provider and account type.

‍

What Can You Do With an Online Bank?

The biggest advantage of digital banking is convenience.

Instead of managing different financial tasks through separate branches and systems, many services can be accessed from a single app.

1: Manage everyday spending

You can use an online bank for everyday purchases, direct debits, standing orders and card payments.

Many apps also categorise transactions, making it easier to understand where your money is going.

2: Send and receive money

Online banking makes domestic transfers straightforward.

You can usually send money to another UK bank account directly from the app and receive payments into your account.

3: Save money

Some digital banking providers offer savings accounts, savings pots or automated saving features.

These can help users separate money for different goals without needing multiple physical accounts.

4: Manage your spending

Budgeting features can provide an overview of your spending and help you identify how much you're spending in different categories.

5: Spend abroad

Many digital financial apps offer foreign currency functionality or cards designed for international spending.

This can be particularly useful for people who travel frequently.

6: Send money internationally

This is an increasingly important consideration.

If you regularly send money from the UK to family, friends or your own account overseas, you should look beyond everyday banking features and compare the provider's international transfer service.

That means checking: Exchange rate + transfer fee + delivery time + amount received

‍

How To Choose the Best Online Banks

A "best online bank" list is only useful if you know how the providers are being evaluated.

Rather than ranking an account simply because it has a popular app, several factors should be considered.

A: Fees

Look at monthly account fees, transfer fees, foreign exchange charges, ATM fees and any other costs that could affect how you use the account.

B: International transfers

For people who regularly send money overseas, this deserves particular attention. Compare the exchange rate, transfer fee, supported currencies and estimated delivery time.

C: Everyday banking

Consider whether the account provides the features you need for payments, direct debits, cards and receiving money.

D: Savings

Look at available savings products and the interest rates applicable to them.

E: Budgeting

Budgeting tools can help you understand your spending and manage your money more effectively.

F: Overseas spending

If you travel regularly, check how the provider handles card payments and cash withdrawals abroad.

G: Security

Look for strong authentication, transaction notifications, fraud monitoring and appropriate regulatory protections.

H: Customer support

Consider how easily you can get help when something goes wrong.

A good online banking experience isn't just about having a good app. It's also about what happens when you need assistance.

‍

‍

What Should You Look for in an Online Bank?

Before opening an account, think about how you actually use your money.

Ask yourself:

1: Do you mainly need everyday banking?

If you want a current account for receiving your salary, paying bills and managing everyday spending, prioritise account functionality, budgeting and customer support.

2: Do you travel frequently?

Look closely at foreign exchange rates, card usage abroad and cash withdrawal policies.

3: Do you regularly send money overseas?

International transfers should become one of your most important comparison criteria.

Don't look only at the advertised transfer fee.

Instead, compare the complete transaction:

4: Do you want rewards?

If cashback or other rewards matter to you, compare the eligibility requirements and whether the rewards justify any associated account costs.

5: Do you want everything in one app?

A broad financial platform may be attractive if you want banking, spending, savings, currency exchange and other services together.

However, using a specialist service for a specific financial need can sometimes provide a better experience.

‍

‍

Are Online Banks Safe?

Security is one of the most important considerations when choosing an online bank.

Digital banking providers use a combination of account authentication, encryption, transaction monitoring and fraud prevention measures to protect customers.

However, you should also understand the regulatory status and protection that applies to the specific provider.

In the UK, eligible deposits held with authorised banks and building societies can be protected by the Financial Services Compensation Scheme (FSCS) up to the applicable limit.

Not every financial app should automatically be assumed to provide the same protection.

Before depositing significant amounts of money, check whether the provider is a bank, which entity holds your money and what protections apply.

You should also take basic steps to protect your account:

• Use a strong password
• Enable biometric authentication where available
• Never share verification codes
• Keep your phone and banking app updated
• Be cautious of unexpected calls, emails or messages
• Check transaction notifications
• Contact the provider immediately if you notice suspicious activity

Convenience is one of the biggest advantages of online banking, but security should remain a priority.

Pros and Cons of Online Banks

Like any financial service, online banking has advantages and disadvantages.

Pros of online banks

1: Convenient access

You can manage your money from your phone without visiting a branch.

2: Fast payments

Many digital banking services make sending and receiving money quick and straightforward.

3: Real-time notifications

You can receive alerts when money enters or leaves your account.

4: Budgeting features

Many apps provide spending categorisation and budgeting tools.

5: International functionality

Some online financial providers make currency exchange and international transfers easier.

6: Easy account opening

Many providers allow you to open an account entirely online.

Cons of online banks

1: Limited branch access

If you prefer face-to-face banking, a digital-only provider may not be suitable.

2: Smartphone dependence

You generally need access to your phone and the internet to manage your account.

3: Features vary between providers

Not every digital bank provides the same products or services.

4: International transfers can differ significantly

Two providers may both offer international transfers but have very different exchange rates, fees, supported destinations and delivery times.

That's why you should compare the specific service you need rather than assuming every online bank works the same way.

‍

‍

How to Open an Online Bank Account

Opening an online account is usually straightforward.

The exact process varies by provider, but you will generally need to:

1. Download the provider's app or visit its website.
2. Enter your personal information.
3. Verify your identity.
4. Provide any required documentation.
5. Wait for your application to be approved.
6. Fund your account if necessary.
7. Set up your card, payments and other services.

You should only open an account with a provider after checking its eligibility requirements, fees and applicable protections.

If you're switching from an existing current account, also check whether the provider supports the Current Account Switch Service.

‍

Can You Use an Online Bank as Your Main Bank?

For many people, an online bank can provide everything they need for everyday banking.

You may be able to receive your salary, pay bills, manage direct debits, use a debit card and transfer money without visiting a branch.

However, whether you should use one as your main account depends on your circumstances.

Consider whether you need:

• Branch access
• Cash deposits
• Specialist banking services
• Overdraft facilities
• International transfers
• Savings products
• Joint accounts
• Business banking

You don't necessarily have to choose just one provider.

Some people use one account for everyday banking and another specialist service for international transfers, travel or savings.

‍

Why International Transfers Matter When Choosing an Online Bank

This is one of the most overlooked parts of comparing online banks.

An app can be excellent for everyday spending and still not provide the best experience for sending money internationally.

If you regularly send money from the UK to another country such as Nigeria, india and other, the cost of transferring money can have a meaningful impact over time.

For example, suppose you send £500 overseas every month. A small difference in the exchange rate or total transfer cost might not look significant on one transaction.

Over 12 months, however, the difference can become much more noticeable.

That's why you should compare four things:

1. Exchange rate: 

What rate will you receive when converting your pounds?

2. Transfer fee

Is there a fixed or percentage-based fee?

3. Delivery time

How quickly should the recipient receive the money?

4. Recipient amount

Most importantly, how much will actually arrive?

The final figure is often the easiest way to compare two services.

‍

Why Consider Pesa for International Money Transfers?

If international transfers are one of your main financial needs, Pesa is an alternative worth considering.

Pesa puts international money movement at the centre of its proposition rather than treating it as just another feature.

A: Zero transaction fees

Pesa advertises zero transaction fees for international transfers. 

B: More than 40 currencies

Pesa supports international transfers across more than 40 currencies, giving users the ability to move money across multiple international corridors. 

C: Transparent transfer information

Pesa provides exchange-rate and transfer information before you complete a transaction, helping you understand the value of your transfer.

D: Fast transfers

Pesa states that many international transfers can arrive within minutes, although actual delivery times depend on the destination, banking partners and other factors. 

E: Built around international money movement

If your main reason for using a financial app is sending money to family, friends or your own accounts abroad, a specialist international transfer experience may be more relevant than choosing an app based solely on its everyday banking features.
