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, and both hold full UK banking licences with FSCS protection up to £120,000 (opens in new tab) (the Financial Services Compensation Scheme: government-backed cover if a bank fails). MoneySavingExpert's digital banking guide (opens in new tab) lists them side by side as leading challengers.

The differences are real but subtle.

Quick comparison

Budgeting: Monzo wins

Starling's Spaces do the same core job as Monzo's pots: ring-fence money into separate buckets inside the account. Starling's spending insights are decent and its automatic categorisation works well.

What Starling has no equivalent to is Salary Sort, which splits your incoming pay across pots the moment it arrives. That is the piece that turns pots from a savings jar into a budgeting system, and it's the reason is Monzo worth it? rates the free account's budgeting layer as its strongest feature. Spaces you have to feed manually; pots feed themselves.

Which pays more interest, Monzo or Starling?

This comparison flipped in Starling's weaker direction. Starling scrapped interest on the current account balance in early 2025, and its instant-access Easy Saver now pays 2.50% AER (Annual Equivalent Rate: the yearly rate including compounding), below Monzo's free rate. Its remaining savings edge is the 3.70% AER 1-year Fixed Saver, a product Monzo doesn't offer at all, though it requires a £2,000 minimum and locks the money in for the full term, with no top-ups and no early withdrawals. The Easy Saver takes withdrawals any time; the Fixed Saver is the one you can't touch.

Monzo's free account offers 2.75% AER on instant-access pots. You can get 3.25% AER on the Perks (£7/month) or Max (£17/month) plans; see Monzo Extra vs Perks vs Max for where those fees break even.

Verdict: Monzo for instant access, Starling for a 1-year fix with £2,000+ you don't need to touch.

Overdrafts: Starling wins

Monzo charges a flat 39% EAR on arranged overdrafts (Equivalent Annual Rate: what the overdraft costs over a year if you stayed in it). Competitive by app-bank standards, 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 the running cost in the app as you borrow, so neither surprises you at the end of the month.

Travel spending: Starling wins (slightly)

Card spending is a dead heat: neither bank charges a foreign transaction fee, and both pass on the Mastercard exchange rate.

Cash is where they part, and only outside the EEA (the European Economic Area: the EU plus Norway, Iceland and Liechtenstein). Inside it, both are free and unlimited. Outside it:

• Monzo: £200/month free, then 3% fee
• Starling: £300/day free, no monthly cap

Starling's allowance is the far more generous one, which is why best UK bank account for travelling abroad rates it ahead of Monzo for cash-heavy trips.

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 spent years without a refer-a-friend scheme, but is now trialling a new one that pays both sides a guaranteed £25 (a typed code during sign-up, then a card payment within 30 days). It's new enough that we haven't been able to test it yet; our Starling referral page tracks its status.

Verdict: Monzo, on a £20 floor and £100 ceiling against a flat £25, and on the fact that a long-established scheme is less likely to vanish than one still in trial.

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 puts most of that in its free tier, so a typical sole trader never reaches a paid plan at all, and it adds a multi-currency business account Monzo has no answer to. Monzo's counter is the tax pots and the accounting integrations, which is what the Pro fee buys: the question is whether setting money aside for a Self-Assessment bill (HMRC's annual return for anyone not taxed purely through payroll) is worth paying monthly for.

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 (opens in new tab) 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.

Which has better customer support, Monzo or Starling?

Both banks offer in-app chat as their primary support channel. Neither has branches. The difference is reputation, not channel.

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

The rate argument used to be Starling's, and it isn't any more. Monzo's free instant-access 2.75% now beats Starling's 2.50% Easy Saver. What Starling keeps is a set of edge cases: a 3.7% one-year fix Monzo doesn't offer, 15-35% overdraft EAR vs Monzo's 39.9%, a £300/day non-EEA ATM allowance vs £200/month. If a banking decision were a spreadsheet comparison, it would now be close to a draw.

It isn't a spreadsheet comparison anyway.

The instant-access gap is 0.25%, now in Monzo's favour. On £10,000 of savings, that's about £25/year, in either direction: not decision-making money. 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. The 1-year fix only matters if you can spare £2,000+ to lock away for the full term.

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. Open Starling as a deliberate secondary if you regularly use an overdraft, withdraw cash abroad, or have £2,000+ to lock into the 1-year fix. (See Best second UK bank account to pair with Monzo for the full pair-and-where guide.) If none of those apply, Monzo on its own is enough.

The bottom line

Opening both costs nothing, and the joining rewards are on opposite ends of the certainty scale: Starling's £25 is guaranteed but untested, while the Monzo referral bonus is a mystery £20, £50 or £100 within 30 days of your first card payment, the biggest of any UK bank's scheme (see our best UK bank referral bonuses comparison).
