In a rush? Monzo wins on budgeting tools, spending visibility, and app polish. Starling wins on business banking, interest on your balance, and fee-free spending abroad with no cap. If you want the best app experience, pick Monzo. If you want the better all-round financial product, pick Starling. If you run a business, Starling is the clear winner.
Monzo and Starling are the two UK digital banks most people narrow their choice down to. They launched within a year of each other. Both are FSCS protected. Both offer current accounts through apps. Both ditched branches entirely. The differences are in what each one prioritises, and those differences matter more than the features they share.
Quick verdict
Monzo is the better daily banking app. Starling is the better bank. Monzo's spending categories, Pots, and budgeting tools make it the best choice if you want to see where your money goes and feel in control of it. Starling's interest on current account balances, uncapped fee-free overseas spending, and stronger business banking make it the better financial product overall. If you run a business, the decision is even simpler: Starling's business accounts are free, Monzo charges for theirs.
Where they are the same
Before the differences, here is what both banks offer. You will not find a winner in this section because there is not one. Both do these things equally well:
- FSCS protection up to £85,000 on deposits
- Fully regulated UK banks, not e-money institutions
- Current Account Switch Service support for easy switching
- No monthly fee on the standard current account
- Instant spending notifications on your phone
- Savings pots or spaces to separate money within the app
- Joint accounts available
- Teen and children's accounts (Monzo: age 6+, Starling Kite: age 6+)
- Google Pay and Apple Pay
- FCA regulated, not just an app sitting on top of someone else's banking licence
If all you need is a free current account with an app and you do not care about anything below the surface, flip a coin. If you want the differences, read on.
App and budgeting: Monzo wins
Monzo built its reputation on the app, and it still deserves it. Spending is automatically categorised. You see exactly what you spent on groceries, eating out, transport, and entertainment without doing any work. The app shows you whether you are on track for the month at a glance.
Starling's app is clean and functional, but the budgeting side is more basic. You can see transactions and categories, but Monzo's presentation, trend graphs, and bill-splitting features feel a generation ahead.
If you want your bank to help you understand your spending and change your habits, Monzo is the better pick.
Spending abroad: Starling wins
Both banks let you spend abroad fee-free. The difference is in the cap. Monzo allows fee-free overseas spending up to £200 per month on the free plan, then charges 3% after that. Starling has no cap at all.
If you travel for more than a weekend trip every couple of months, Starling's uncapped fee-free overseas spending will save you more money. If you only leave the UK once or twice a year for short trips, Monzo's £200 monthly cap probably covers you fine.
Interest on your balance: Starling wins
Starling pays interest on your current account balance. The rate is not the highest on the market, but getting paid interest on money sitting in your current account rather than needing to move it to a separate savings pot is a genuine advantage.
Monzo does not pay interest on current account balances. You can earn interest through Monzo's savings pots, but you need to move money into them. Starling pays you for doing nothing.
Business banking: Starling wins by a distance
Starling's business account is free. Monzo charges for theirs: the Lite plan starts at £5 per month. Starling also offers a wider range of business features including 24/7 support, integration with accounting software, and a stronger business product overall.
If you run a business, even a small one, or you are a sole trader or freelancer, Starling's free business banking is one of the best deals in UK banking. Monzo's business account is decent but you pay for it.
Paid plans and premium features
Both banks offer paid upgrades on top of the free account:
- Monzo Plus (£5/month): virtual cards, custom categories, credit score tracking, interest on Pots.
- Monzo Premium (£15/month): worldwide travel insurance, phone insurance, airport lounge access, metal card. Uncapped fee-free overseas spending included.
- Starling Kite: free debit card for kids aged 6-16, managed from your Starling app.
Monzo's paid plans are more developed and make more sense if you want bundled insurance and travel perks. Starling keeps things simpler with fewer add-ons.

When to pick Starling
- You want interest on your current account balance without moving money anywhere.
- You travel frequently and need uncapped fee-free overseas spending.
- You run a business, freelance, or are a sole trader who needs a free business account.
- You want a straightforward, well-built banking app without gamification.
- You want a free debit card for your kids with Starling Kite.
Can you have both?
Yes. Plenty of people do. Use Starling for your main current account where your salary lands, where you earn interest on the balance, and for your business if you have one. Use Monzo for daily spending money, budgeting, and keeping your discretionary expenses visible. The two apps together cover more ground than either one alone, and neither charges a monthly fee for the basic account.
My take
I use Monzo for daily spending because the budgeting tools genuinely changed how I think about where my money goes. I use Starling for business banking because it is free and works. If I had to pick one as my only current account, it would be Starling for the interest and the uncapped overseas spending. If I had to pick one app I enjoy opening, it would be Monzo. The good news is you do not have to choose. Open both. They are free.
