Monzo vs Starling Bank: which digital bank is better in 2026?

Affiliate disclosure: this post contains a Monzo referral link. If you use it, we both get a mystery reward of £20, £50, or £100. It doesn't change anything about your account.

Monzo and Starling are the two most-compared digital banks in the UK, and for good reason. Both are free, both are app-only, both have full UK banking licences with FSCS protection up to £120,000, and both are genuinely good. MoneySavingExpert rates them side by side as the top two digital banks.

The differences are real but subtle. This comparison covers where each one actually wins.

Quick comparison

Budgeting: Monzo wins

This is where Monzo has always had the edge, and it's still true in 2026.

Monzo's pots are genuinely useful: separate savings buckets inside your account where you can ring-fence money for bills, holidays, emergencies, or anything else. You can set automatic transfers, round up spare change into pots, and use Salary Sort to split your pay across pots on payday. Add the spending trends and category breakdowns, and you have a budgeting system that works without needing a separate app.

Starling's Spaces are functionally similar (they let you separate money into goals), but the implementation feels simpler. Starling's spending insights are decent, and automatic categorisation works well, but there's no equivalent to Salary Sort. If you want the bank to do the heavy lifting on budgeting, Monzo does more out of the box.

Verdict: If you opened a bank account primarily for budgeting, pick Monzo.

Savings rates: Starling wins

Starling offers 3.00% AER on its Easy Saver (instant access) and 3.80% AER on a 1-year fixed saver. Both are available within the app and protected by the FSCS.

Monzo's free account offers 2.75% AER on instant-access pots. You can get 3.25% AER by upgrading to Monzo Max (£17/month), but that introduces a monthly fee that eats into the benefit unless you have substantial savings.

For straightforward savings within your bank app, Starling's rates are higher with no monthly fee attached.

Verdict: Starling, unless you're already paying for Monzo Max.

Overdrafts: Starling wins

This is one of the starkest differences.

Monzo charges a flat 39% EAR on arranged overdrafts. It's competitive by app-bank standards, but expensive in absolute terms.

Starling charges 15%, 25%, or 35% EAR depending on the amount borrowed and your creditworthiness. The 15% rate on smaller overdrafts is significantly cheaper than Monzo's flat 39%.

Both show your overdraft cost in real time in the app, so there are no surprises. But if you regularly use an overdraft, Starling could save you a meaningful amount over the year.

Verdict: Starling, especially for smaller overdraft amounts.

Travel spending: Starling wins (slightly)

Both banks offer no foreign transaction fees on card payments abroad: you get the Mastercard exchange rate, which is consistently close to mid-market.

The difference is in ATM withdrawals outside the EEA:

• Monzo: £200/month free, then 3% fee
• Starling: £300/day free, effectively unlimited for most travellers

If you're someone who withdraws cash abroad regularly, Starling's limit is far more generous. For card-only travellers (most people these days), both are identical.

Verdict: Starling has the edge on ATM limits. Card spending is identical.

Referral bonus: Monzo wins

Monzo currently offers a mystery reward of £20, £50, or £100 when you sign up via a referral link and make a card payment within 30 days. Most people receive £20, but the potential upside is higher than any other UK digital bank.

Starling offers a £25 referral reward: guaranteed but fixed.

Verdict: Monzo's floor (£20) is lower than Starling's guaranteed £25, but the potential ceiling (£100) is much higher. If you're risk-neutral, Monzo's expected value is probably similar. If you want certainty, Starling's £25 is straightforward.

Business banking: depends on your needs

Both banks offer free business accounts for sole traders and freelancers, but they differ in approach.

Monzo Business has a free Lite plan for basics, with Pro (from £5/month) adding invoicing, tax pots (automatically sets aside a percentage of income for tax), and accounting integrations with Xero, FreeAgent, Sage, and QuickBooks. Read our full Monzo Business for freelancers review.

Starling Business offers a free account with more features included out of the box: no paid tier needed for most sole traders. Starling's multi-currency business account is a standout feature for anyone receiving international payments.

Verdict: Starling for a free, full-featured business account. Monzo for tax pots and accounting integrations (if you'll pay for Pro).

App experience: personal preference

Both apps are fast, well-designed, and regularly updated. The differences are more about style than substance:

• Monzo feels more social and feature-rich: bill splitting, Monzo-to-Monzo instant payments, connected accounts (see other banks in the Monzo app), and a broader range of budgeting tools
• Starling feels cleaner and more focused: less clutter, straightforward navigation, excellent search

MoneySavingExpert's polling rates both highly: Monzo scored 85% "great" for features, the highest of any digital bank. Starling scored slightly lower on features but matched or beat Monzo on overall satisfaction.

There's no wrong choice here. Download both and use whichever feels right after a week.

Customer support

Both banks offer in-app chat as their primary support channel. Neither has branches.

Monzo's chat is generally responsive (usually under 10 minutes in my experience), but busy periods can push wait times to 30+ minutes. Starling's support is consistently praised for speed and quality; they've won "Best British Bank" at the British Bank Awards multiple times, partly on the strength of their customer service.

Verdict: Starling has the edge on support reputation, though Monzo's chat is perfectly adequate.

The verdict: pick Monzo as your primary

Starling beats Monzo on the things you can put in a table: 3% vs 2.75% on instant access, a 3.8% one-year fix Monzo doesn't offer, 15-35% overdraft EAR vs Monzo's 39.9%, £300/day non-EEA ATM allowance vs £200/month. If a banking decision were a spreadsheet comparison, Starling would win.

It isn't a spreadsheet comparison.

The savings-rate gap is 0.25%. On £10,000 of savings, that's about £25/year. Starling's cheaper overdraft only matters if you regularly run an overdraft, and the responsible answer to "I regularly run an overdraft" is to stop, not to switch banks. The ATM advantage only matters if you withdraw more than £200 of cash outside the EEA in a single month, which most people never do.

What you'd actually use daily on either of these banks is the budgeting layer. Monzo's pots, salary sorting, spending targets and committed-spending forecasting do meaningfully more than Starling's Spaces. After nine years on Monzo, the budgeting tools are the feature I still notice the absence of when I open someone else's banking app. The interest-rate difference, on the other hand, I would not notice.

Pick Monzo for primary. If you hold £5,000+ in savings and want to optimise the rate, open Starling alongside as a savings sidecar. (See Best second UK bank account to pair with Monzo for the full pair-and-where guide.) If you don't, Monzo on its own is enough.

The bottom line

For most people, the right answer is Monzo as the primary and, if savings sit at £5,000+, Starling as a sidecar earning a slightly higher rate on cash you don't need this week.

The Monzo referral bonus is a mystery reward of £20, £50 or £100 within 30 days of your first card payment, against Starling's flat £25. If you're going to open one of them anyway, Monzo's expected value is a bit higher.
