Apps like Monzo, Starling, Revolut and Wise look the same on the screen. The licences sitting behind them are different — and the difference decides what happens to your money if the firm ever fails.

If you bank with one of the well-known UK app brands you may have seen the news that Revolut secured its full UK banking licence in March 2026 — the end of a process that had stretched on for years. For most customers the headline reads as a milestone, not a change. What it actually settles — for you, for your money, and for what happens if the worst ever happens — is less obvious unless you know the regulatory distinction it is finally resolving.
That distinction is the difference between an authorised bank and an electronic money institution. Apps like Monzo, Starling, Revolut, Wise and Curve all look essentially identical on the screen. The licences sitting behind them are not, and the gap between the two matters most precisely when you would least want it to: when the firm holding your money runs into trouble. This article walks through what each licence is, what FSCS protection actually covers, and how to check what your “bank” really is in five minutes.
Most banking apps in the UK fall into one of two regulatory buckets, and the bucket determines almost everything about what happens to your money behind the screen.
An authorised bank. Dual-regulated by the Prudential Regulation Authority (PRA, part of the Bank of England) and the Financial Conduct Authority (FCA). A banking licence grants permission to take deposits — meaning the money you pay in becomes a deposit on the bank’s balance sheet, and the bank can lend it out, subject to capital rules, liquidity requirements and the rest of the regulatory machinery. Deposits at an authorised UK bank are covered by the Financial Services Compensation Scheme (FSCS).
An electronic money institution (EMI). Authorised by the FCA alone, under the Electronic Money Regulations 2011. An EMI is not a bank. It can issue “electronic money” — the prepaid balance you load and spend — and run payment services. What it cannot do is take deposits in the legal sense. Your funds with an EMI are not deposits and not on the firm’s balance sheet; they are customer money that the firm is legally required to safeguard.
Safeguarding means the EMI must either hold customer funds in a designated account at a real authorised bank, or invest them in approved low-risk assets, ring-fenced from the firm’s own money. It is real protection — but it is structurally different from FSCS deposit protection, and that structural difference is what matters when something goes wrong.
The two licence types diverge sharply when the firm gets into trouble. The day-to-day experience is identical; the failure-day experience is not.
If an authorised UK bank fails, the FSCS steps in. Eligible deposits are compensated up to £120,000 per person, per banking licence — raised from £85,000 in December 2025. For simple current and savings accounts the FSCS aims to pay out within seven working days. You do not need to apply; the scheme contacts customers automatically using bank records. For most ordinary savers this is the silent backstop that means a UK bank failing is an inconvenience, not a catastrophe.
If an EMI fails, there is no FSCS payout. What happens instead is an insolvency process: an administrator takes control, identifies the safeguarded customer funds (the money the firm was required to keep ring-fenced), and returns those funds to customers — after the administrator’s costs have been deducted. In a clean case you get back broadly what you held. In a messier case — safeguarding mistakes, missing records, fund mingling — you may get back less, and it may take months rather than days.
For most people, the bank-versus-EMI distinction is invisible right up until the moment it isn’t. The chance of a UK firm of either type failing in any given year is small. The cost when it happens is largest where you assumed FSCS would catch you and the rules turned out to read differently.
Here is roughly how the well-known names line up.
Full UK banks (FSCS-protected up to £120,000). Monzo, Starling, Chase UK and Atom all hold full UK banking licences. The high-street incumbents — Lloyds, NatWest, Barclays, HSBC, Santander, Nationwide and the rest — obviously do too. Money sitting in a current or savings account with any of these is on the bank’s balance sheet and within scope of FSCS protection.
Revolut — now a bank, with a transition period. Revolut Ltd operated as an EMI in the UK for years while its licence application worked through the regulators. In March 2026 the PRA granted it a full UK banking licence. The next phase is what the regulators call mobilisation — a standard step for any new UK bank, during which the bank operates with restrictions (typically capped deposit amounts) while it builds out its operations before opening fully. Existing Revolut customer funds remain in the e-money entity (safeguarded) until they are migrated across to the new banking entity. The practical message: check Revolut’s own communications about which entity holds your balance and from when, and use the FCA Register to confirm.
Still e-money (safeguarded, not FSCS-protected). Wise and Curve are both electronic money institutions in the UK — substantial businesses, subject to safeguarding rules, but not banks. So are most of the prepaid-card and payment apps you might use for travel, splitting bills or specific spending categories. The general pattern: if the brand markets itself around payments, transfers or low-fee spending rather than around deposits and lending, there is a fair chance it is an EMI rather than a bank.
None of this is a criticism of any particular firm. EMIs are properly regulated, the safeguarding rules are real, and many of them are perfectly sensible places to hold spending money. The point is that the protection works differently, and the marketing rarely makes that obvious.
The definitive check takes a couple of minutes:
If you want to know specifically whether your money is FSCS-protected, and up to what limit, the FSCS’s own check tool is also worth using — it covers the deposit-protection question directly and handles brands that share a single banking licence.
“But my money is held in a real UK bank account — isn’t that the same thing?” Many EMIs safeguard customer funds by holding them in a designated account at an authorised bank. So technically the money does sit in a UK bank. What protects you in a failure scenario, however, is the EMI’s safeguarding obligation and the insolvency process for the EMI — not direct FSCS deposit cover on the underlying bank account, which belongs to the EMI rather than to you.
“FSCS covers everything I’d hold with a financial firm, surely?” No. FSCS covers specific products: deposits at authorised banks (up to £120,000), certain investment activities (up to £85,000), insurance and a few others. E-money balances are explicitly not on the list. Investments at a stockbroker are protected for the stockbroker’s failure, but not for losses in the investments themselves. The scheme is generous, but it is not a universal financial backstop.
“If a firm is FCA-authorised, it’s automatically safe.” Authorisation is a regulatory threshold — the firm has met the FCA’s requirements to operate. It is not a stamp of guaranteed safety, and on its own it does not tell you which protection scheme applies to your money. The same FCA Register that confirms authorisation also lists what permissions the firm holds and, by implication, which protection regime applies. Both pieces of information sit on the same page.
A few facts about the headline number that catch people out.
The shared-licence point is the one most likely to bite. Some well-known high-street brands sit under a parent group’s single banking entity; others under the same group operate as a separately licensed bank. You cannot reliably tell which is which from the brand alone — another reason the FCA Register and the FSCS check tool are worth a few minutes of your time if you have meaningful balances spread around.
The chance you will ever need any of this in anger is, statistically, small. UK bank failures are rare, EMI failures are rarer still in terms of customer impact, and the safeguarding regime has held up in the cases that have happened. The case for understanding the distinction is not that the sky is likely to fall — it is that the sky-falling scenario is exactly the moment to discover, rather than learn, that your money was held under a regime you assumed worked differently.
Revolut’s licence settles that question for its UK customers over the coming months. For everyone else the five-minute test is the same as it has always been: open the FCA Register, type the brand name, read the permission line. Once you have done that for the apps you actually use, you can return to the original promise of any well-built banking app — that you don’t have to think about this stuff every day — with the difference that you have, just once, checked.
