Picking a business bank account should be a five-minute decision but in practice, it rarely is. Starling and Monzo sit at the top of almost every UK recommendation list for digital business banking, and they're genuinely similar in several important ways. Both are fully licensed UK banks with FSCS protection, both are mobile-first, both charge nothing for basic UK transfers, and both are significantly cheaper to run than a traditional high-street account.
But the differences between them matter, and they tend to matter specifically depending on how you work.
This guide is written for UK freelancers, sole traders, and small limited company owners deciding between the two. We'll look at pricing, features, the things neither bank will readily advertise, and who should realistically pick which.
Note: Nothing in this article constitutes financial advice. Costs, features and eligibility criteria can change always verify current terms directly with each provider before applying.
Before getting into where they diverge, it's worth establishing the common ground, because there's quite a lot of it.
Both Starling and Monzo are fully regulated UK banks, authorised by the FCA and the Prudential Regulation Authority. Both offer FSCS protection up to £120,000 on eligible deposits. Neither is an e-money institution operating through a third-party bank, a meaningful distinction that matters for deposit protection and trust.
Both accounts offer:
That's a solid foundation. The divergence happens in pricing structure, cash handling, software longevity, international payments, and team features.
This is the most important practical difference between the two banks, and it's one that catches people off guard.
Starling's business account is genuinely free for the vast majority of small UK businesses. There are no monthly fees for the core account, no charges for UK electronic payments, and no fees for ATM withdrawals, either in the UK or abroad. The free account also includes accounting software integrations with Xero, QuickBooks and FreeAgent at no extra cost, which is notably different from Monzo's approach.
The optional Starling Accounting add-on (formerly the Business Toolkit) costs £7/month and adds invoicing, VAT management, enhanced categorisation and tax tools. But you don't need it to connect your accounting software, that's already included for free.
Cash deposits at the Post Office cost 0.7% (minimum £3). International transfers carry a 0.4% conversion fee. These are the fees most business owners will encounter.
Monzo uses a tiered model:
| Plan | Monthly Cost | Key Additions |
|---|---|---|
| Lite | Free | Core banking, pots, debit card, UK transfers |
| Pro | £9/month | Accounting integrations, invoicing, tax pots |
| Team | £25/month | Multi-user access, expense cards, spend controls |
Here's the catch that trips up a lot of freelancers and small business owners: if you want to connect Monzo to Xero, QuickBooks or FreeAgent, you need the Pro plan at £9/month. Starling includes this in its free tier.
For a sole trader or small limited company that relies on accounting software which is most of them. Monzo's "free" account is functionally limited. The real comparison for most users is Starling free vs Monzo Pro at £9/month, or Starling's £7/month add-on vs Monzo Pro.
Neither is egregiously expensive, but it's worth being clear-eyed about what "free" actually means for each bank's base tier.
Tip: If you mainly use spreadsheets or your accountant handles bookkeeping separately, Monzo Lite's free tier works perfectly well for day-to-day banking. If you run your own books through accounting software, factor in the additional cost of Monzo Pro.
Cash handling is where Starling and Monzo differ most significantly, and it's a genuine dealbreaker for certain businesses.
Starling allows you to deposit up to £3,000 in cash per month for free at the Post Office, with a 0.7% fee (minimum £3) applying thereafter. That's generous, and useful for businesses that take cash payments, tradespeople, market stall holders, hospitality operators and similar.
Monzo offers only £500 in free cash deposits monthly, charging £1 per deposit beyond that. For businesses that regularly handle cash, the difference adds up quickly.
If your business is entirely digital, payments by bank transfer, invoice or card, this distinction is largely irrelevant. But if cash comes through your door, Starling is the more practical option.
Both banks have limitations here, though they handle them differently.
Starling supports international transfers to 34 countries directly, with a 0.4% conversion fee. It offers EUR and USD accounts as optional add-ons (£2/month and £5/month respectively), though as of 2026, these are currently unavailable to new customer, a frustrating gap if you regularly invoice clients in Europe or the US.
Monzo doesn't process outbound international transfers directly at all, instead routing them through Wise, which requires a separate Wise account. Inbound international payments are accepted, but carry a 1% conversion fee to GBP. If you regularly receive foreign currency payments, that 1% accumulates.
For businesses with significant international operations, regular overseas suppliers, clients in the EU, billing in USD, neither bank is the ideal primary solution. You'd likely want to supplement either with a dedicated multi-currency account (Wise, Revolut Business or Airwallex are commonly used alongside both).
For most UK-focused freelancers and small businesses that occasionally deal internationally, both banks handle it adequately.
Both banks work well for self-employed individuals, but they suit different working styles.
Starling is a stronger fit for freelancers who want banking that mostly gets out of the way. The free tier is comprehensive, accounting integrations, spending spaces, instant notifications and no transaction fees and there's relatively little pressure to upgrade. The app is stable and mature. The web banking interface is solid. For someone who wants reliable, low-maintenance business banking with no monthly commitment, Starling is hard to argue with.
Monzo has a reputation for a slightly more polished, consumer-app-style experience. The spending pots (including dedicated Tax Pots that automatically set aside a percentage of incoming payments) are particularly well-regarded by freelancers who struggle to ring-fence money for self-assessment. The interface tends to feel more intuitive to users who are already familiar with Monzo as a personal banking customer.
If you already use Monzo personally and find the app genuinely useful, the transition to a Monzo business account is frictionless, you manage both from the same app.
If you're running a limited company with employees or regular contractors, the picture shifts.
Starling lets you add multiple directors to the same account, which is a standard requirement for limited companies. It doesn't offer full multi-user team expense management in the way that Monzo Team does.
Monzo's Team plan (£25/month) is specifically designed for businesses with staff: it offers shared account access, expense cards for team members with customisable spending limits, bulk payments and approval controls. For a small company with, say, three or four employees who need their own company cards, this is genuinely useful functionality.
If you're a sole director of a limited company with no employees, this distinction doesn't apply. If you have a team that makes business purchases, Monzo Team or an alternative like Tide or Revolut Business may be worth comparing alongside both.
Both banks are profitable (Starling reached profitability ahead of Monzo) and well-established. Neither is a fragile startup. That said, there are a few practical notes worth flagging.
Starling's app and web banking are mature and stable. Its customer satisfaction scores are consistently strong. Starling won Finder's 2026 Business Bank Accounts Customer Satisfaction Award, with 100% of surveyed customers saying they would recommend it.
Monzo's Trustpilot score is marginally higher overall (4.6 out of 5 stars from over 65,000 reviews), though those ratings cover both personal and business accounts. Its business product is slightly newer, having launched its first business account in 2020, four years after Starling entered the space.
Making Tax Digital (MTD) compatibility is worth a mention for sole traders and small businesses planning for HMRC's expanding digital tax requirements. Monzo has a waiting list for its MTD software and is listed as "Ready" on HMRC's software finder tool, though full rollout is still in progress. Starling is in a similar position, a waiting list is currently in place. Tide currently has the first-mover advantage on MTD integration, which is worth considering if MTD compliance is an immediate priority.

Q: Is Starling or Monzo better for a freelancer just starting out?
For a freelancer with no staff and no regular cash income, Starling's free account is typically the stronger starting point. You get accounting software integration at no cost, and there's nothing to upgrade unless you want invoicing and VAT tools. Monzo Lite works well too, but you'll hit the accounting integration wall quickly if you use Xero or QuickBooks.
Q: Can I have both a Starling and Monzo business account?
Yes. There's no rule preventing you from holding accounts with both, and some business owners keep one as a primary trading account and the other as a secondary account for specific purposes. That said, for most freelancers and small businesses, one well-chosen account is all that's needed.
Q: Is my money safe in Starling or Monzo?
Both are fully licensed UK banks regulated by the FCA and PRA. Eligible deposits up to £120,000 are protected by the FSCS, the same protection you'd have with a high-street bank. Neither is an e-money institution, which is an important distinction from some other digital finance apps.
Q: Which bank is better for international payments?
Neither is optimal for businesses with significant international needs. Starling handles international transfers more directly, but has paused EUR and USD accounts for new customers. Monzo routes international payments through Wise and charges 1% on incoming foreign currency. For businesses with regular international transactions, supplementing either with Wise or a multi-currency account is worth considering.
Q: How long does it take to open a business account with each?
Both can be opened quickly. Starling typically approves sole trader accounts in under 10 minutes; limited company accounts usually come through within 24-48 hours, though some may take longer. Monzo similarly processes most applications the same day, with some taking up to a week depending on verification requirements.
Starling and Monzo are both excellent choices for UK freelancers and small business owner, significantly better than most traditional bank alternatives at this price point. But they suit slightly different people.
Choose Starling if cost minimisation is your priority. Its free tier is genuinely more capable than Monzo's equivalent, particularly for anyone using accounting software. The higher cash deposit limit and more mature international transfer feature add further practical advantages for certain business types.
Choose Monzo if you're already embedded in the Monzo ecosystem, if you find its interface more intuitive, or if you're managing a small team that needs shared expense cards. The Tax Pot feature is a genuine differentiator for freelancers who struggle to manage self-assessment savings.
The most important thing isn't which bank is theoretically "better", it's which one fits how you actually work. Both will handle day-to-day business banking competently. The differences show up in the specifics.
