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 the same randomised £5, £10 or £20. 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?

Flexible money earns more at Starling, but only for 6 months. Its instant-access Easy Saver pays 4.00% AER (Annual Equivalent Rate: the yearly rate including compounding), and 1.50% of that is a fixed bonus on balances up to £25,000 that runs for your first 6 months only. A new customer who opens the Easy Saver within 30 days of opening a Starling current account gets a 2.50% bonus instead, for 5.00%. From month 7 the rate is 2.50%, below Monzo's free rate. Starling scrapped interest on the current account balance in early 2025, so the Easy Saver is where its flexible rate lives.

Monzo's free account offers 2.75% AER on instant-access pots, rising to 3.00% on Extra (£3/month), 3.25% on Perks (£9/month) and 3.50% on Max (£19/month); see Monzo Extra vs Perks vs Max for where those fees break even.

Money you can lock away for a year earns more at Monzo. Its 1-year Fixed Rate Pot pays 4.70% AER from a £500 minimum, and you can close it early by giving up some of the interest. Starling's 1-year Fixed Saver pays 4.20% AER, needs £2,000, and takes no top-ups and no early withdrawals. Both fixes beat holding Starling's Easy Saver for the same year: on £10,000, Monzo's fix earns £470, Starling's £420, and the Easy Saver about £325 (6 bonus months, then 6 at 2.50%).

Verdict: lock a year's savings into Monzo's fix, and keep flexible savings in Starling's Easy Saver only while the bonus runs. On £10,000 the 6 bonus months earn about £60 more than Monzo's free 2.75% would (about £110 at the new-customer 5.00%), so the Easy Saver is worth a diary note for when the bonus ends.

Overdrafts: Starling wins

Monzo charges 19%, 29% or 39% EAR on arranged overdrafts (Equivalent Annual Rate: what the overdraft costs over a year if you stayed in it), with the tier set by your credit score and 39% APR as its representative example. Expensive in absolute terms at every tier.

Starling charges 15%, 25%, or 35% EAR on the same basis. It undercuts Monzo by four percentage points at each of the three tiers, so whichever band you land in, Starling's is the cheaper overdraft.

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, mostly outside the EEA (the European Economic Area: the EU plus Norway, Iceland and Liechtenstein). Inside it, both are free and unlimited, Monzo's only if it is your main account. 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: Starling on paper, Monzo in practice

Our Monzo link pays a randomised £5, £10 or £20 when you sign up through it and make a card payment within 30 days, on published odds of 94%, 5% and 1%. That averages £5.40. Until August 2026 the same odds ran on £20, £50 and £100, which was the biggest referral of any UK digital bank, so Starling's £25 is now the larger of the two on average.

Starling's previous refer-a-friend scheme gave both sides a National Trust pass, and it is now trialling a cash one that pays both sides a guaranteed £25 (a typed code during sign-up, then whatever reward conditions that promotion sets in the app). It's new enough that we haven't been able to test it yet; our Starling referral page tracks its status.

Verdict: Starling pays more on average, and almost nobody can claim it. Its codes go only to customers it invites into the trial, so no website can hand you one, while any Monzo customer can pass their link to anyone. If you know a Starling customer who has been invited, take the guaranteed £25. Otherwise Monzo's draw is the one that exists for you, and one reader in a hundred beats the £25 with it.

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 (£9/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 guide to app-based banks (opens in new tab), updated 20 October 2026, agrees on budgeting, crediting Monzo with the "best budgeting tools", though it names Starling its top all-rounder.

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. In MoneySavingExpert's July 2026 customer-service poll, 84% of Starling customers rated its service "great", against 77% for Monzo.

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 is split, and mostly Monzo's: Starling's Easy Saver beats Monzo's free 2.75% for 6 months, then reverts to 2.50% and sits below it, and Monzo's 4.70% one-year fix beats Starling's 4.20%. What Starling keeps for good is a pair of edge cases: 15-35% overdraft EAR against Monzo's 19-39%, and a £300/day non-EEA ATM allowance against £200/month. If a banking decision were a spreadsheet comparison, Starling would win 6 months of flexible savings and Monzo every other savings line.

It isn't a spreadsheet comparison anyway.

The instant-access gap is 1.25% in Starling's favour for 6 months (2.25% for a new customer), then 0.25% in Monzo's. On £10,000 of savings that's about £60 over those 6 months (£110 for a new customer) and roughly £25/year back the other way from then on: worth a standing order, not worth picking a primary account over. 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. Open Starling as a deliberate secondary if you regularly use an overdraft, withdraw cash abroad, or want the Easy Saver's 6-month bonus on flexible savings. (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 neither joining reward is a reason to do it: Starling's £25 is guaranteed but untested, and the Monzo referral bonus is a random £5, £10 or £20 within 30 days of your first card payment (see our best UK bank referral bonuses comparison).
