Starting a side hustle is exciting, but managing your business finances can quickly become overwhelming without the right tools. One of the first major decisions you’ll face is choosing a business bank account that fits your needs. For UK side hustlers, who often juggle their main job alongside growing their business, it’s vital to find an account that offers low fees, easy-to-use apps, and fast account setup so you can start trading without delays.
Many UK banks now offer business accounts designed specifically for small businesses and side hustlers, but not all are created equal. We opened five popular business bank accounts to test them on three key criteria: fees, app quality, and speed of activation. This hands-on approach gives you a clear picture of what to expect and helps you avoid any nasty surprises.
Why Your Choice of Business Bank Account Matters for Side Hustlers
Separating your personal and business finances is not just good practice — it’s essential for tax purposes, especially when dealing with HMRC. Using a dedicated business bank account helps you track income and expenses accurately, making your Self Assessment returns easier and reducing the risk of errors that could trigger an HMRC enquiry.
Aside from tax compliance, the right bank account can save you money on fees, integrate with popular accounting software, and provide flexibility as your side hustle grows. Since many side hustlers operate on tight margins, choosing an account with minimal fees and good mobile banking features is a smart move.

- Access banking features designed for small businesses, like invoicing and payment links.
- Benefit from tools that sync with accounting software such as Xero or QuickBooks.
- Ensure faster payments and deposits to manage cash flow efficiently.
If you’re a sole trader with turnover under £1,000, you might not be legally required to have a business bank account. However, opening one can still simplify your finances and make you look more professional to clients.
How We Tested the Five UK Business Bank Accounts
To find the best business bank accounts for side hustlers, we opened accounts with Revolut Business, Tide, Starling Bank, Monzo Business, and HSBC Business Current Account. We assessed each based on three critical factors:
- Fees: Monthly charges, transaction costs, and hidden fees that could eat into your profits.
- App Quality: User experience, reliability, features like invoicing, notifications, and integration capabilities.
- Speed of Setup: How quickly you can open the account and start receiving payments.
We also considered customer support responsiveness and any additional perks such as cashback or lending options tailored for small businesses.
1. Revolut Business: Best for Digital Flexibility and Currency Handling
Revolut has rapidly grown its business account offering, especially appealing to side hustlers who deal with international clients or multiple currencies. Opening the account was straightforward and could be done fully online within a few hours. The app is modern, packed with useful features, and supports instant payment notifications.
The free plan offers limited monthly transfers and card payments, after which fees apply. Paid plans start from £7 per month but unlock higher limits and additional features like multi-currency accounts and automated expense categorisation.
Revolut’s strength lies in its global currency capabilities, making it ideal if your side hustle involves international sales or clients. However, it’s worth noting that it’s not a traditional bank and does not offer lending or overdrafts.
- No monthly fee on free plan, but limited free transfers.
- Supports 28 currencies with real-time exchange rates.
- Good invoicing and expense management tools.
- Fast online account setup and instant virtual cards.
2. Tide: Best for Fee Transparency and Quick Setup
Tide is designed specifically for UK small businesses and side hustlers who want a no-nonsense banking experience without hidden fees. The account opening process was impressively quick — we were able to start trading within 24 hours of application, thanks to Tide’s streamlined KYC (Know Your Customer) checks and instant digital onboarding.
There are no monthly fees for the basic account, and transaction costs are transparent. Tide also offers free UK bank transfers and incoming payments. The app is user-friendly and includes features like invoice creation and payment tracking, which can be a lifesaver for side hustlers managing multiple clients.
One downside is that Tide doesn’t currently offer overdrafts or credit facilities, so you’ll need to plan your cash flow carefully.
- No monthly fees on basic account.
- Free UK bank transfers and incoming payments.
- Fast setup: account ready within 24 hours.
- Simple invoicing and payment reminders.
Many business bank accounts charge monthly fees even if your turnover is low. For side hustlers, Tide’s zero monthly fee with useful features is a great way to keep costs down while you grow.
3. Starling Bank: Best All-Rounder with Full FCA Banking Licence
Starling Bank is a fully licensed UK bank with a strong reputation for excellent mobile banking and customer support. Opening an account took less than 48 hours, and you can start receiving payments almost immediately. The app is polished, with detailed spending insights, instant payment notifications, and integration with accounting packages like Xero and QuickBooks.
Starling offers a free business account with no monthly fees and unlimited free UK bank transfers, which is ideal for side hustlers with regular transactions. It also provides overdraft facilities and business loans, which can be useful as your side hustle scales up.
One limitation is that Starling currently does not support cheque deposits, but this is less relevant for most modern side hustlers.
- No monthly fees and unlimited free UK transfers.
- Full FCA regulated bank with FSCS protection.
- Overdrafts and lending available for business growth.
- Excellent app with accounting integrations.
4. Monzo Business: Best for Personalised Customer Support
Monzo is a popular challenger bank in the UK, and its business account focuses heavily on customer experience. Account setup was smooth, but took slightly longer than Revolut or Tide due to additional identity verification. The app is intuitive and offers features like instant notifications, categorised spending, and easy expense tracking.
Monzo charges a monthly fee of £5 for its business account, which includes one free payment to other UK banks per month, with a small charge on subsequent payments. The account supports integration with accounting software and offers business loans, making it a good option for side hustlers planning to expand.
Monzo’s standout feature is its customer support team, which is praised for responsiveness and helpfulness, a key consideration when you’re running a side hustle with limited time to waste.
- £5 monthly fee with one free UK payment per month.
- Smooth app experience with categorised spending.
- Good customer support and community forums.
- Supports business loans and accounting software.
5. HSBC Business Current Account: Best for Established Side Hustlers
For side hustlers who want the reliability of a traditional high-street bank, HSBC offers a business current account with comprehensive features and access to physical branches across the UK. The application process is more involved and took about a week to complete, including a face-to-face verification step.
HSBC charges a monthly fee of £8 for the Business Current Account, which includes unlimited electronic payments and access to overdrafts and loans. Their mobile app is solid but less innovative compared to challenger banks. However, having branch access and relationship managers can be invaluable for side hustlers who need personal banking advice.
If your side hustle is moving towards becoming a full-time business, HSBC’s offerings might provide the stability and support you need.
- £8 monthly fee with unlimited payments.
- Access to overdrafts, loans, and branch support.
- Reliable but less feature-rich app.
- Suitable for transitioning from side hustle to full business.
Traditional banks like HSBC often require more documentation and may take up to a week or longer to approve your account, potentially delaying when you can start trading.
How to Choose the Right Business Bank Account for Your Side Hustle
With so many options available, it can be tricky to pick the best business bank account. Here are some practical steps to help you make the right choice:
- Assess your transaction volume and types of payments you’ll make or receive.
- Determine whether you need multi-currency support or international payments.
- Consider your budget for monthly fees and transaction charges.
- Evaluate the importance of app features like invoicing, integration, and notifications.
- Think about whether you’ll need overdraft or lending facilities soon.
- Check how quickly you need the account to be active to start trading.
- Read customer reviews and test customer support availability.
Remember, your side hustle’s banking needs might evolve as your business grows, so choose an account that can scale with you or be easily switched without too much hassle.
