Plum is a UK money app that automatically squirrels away small amounts you won't miss, then puts those savings to work in interest-earning pockets, a Cash ISA, or low-minimum investments. It launched in 2016 and now has over 2 million customers across the UK and Europe. The app connects to your existing bank account via Open Banking and uses your spending patterns to work out what you can afford to set aside each week.
Plum suits people who find regular saving hard. If you've tried standing orders before and they never stick, the auto-saver does the work in the background and most users barely notice the deposits going out. It's also a friendly first stop for new investors with smaller pots: minimums start at £1 and a curated fund range keeps the choices simple.
The free Basic plan is enough for casual savers and round-up fans; the paid tiers (Plus, Boost, and Max, from £3.99 to £14.99 a month as of May 2026) really earn their keep only if you want the top interest rates or lower investment fees. If you'd rather have hands-on control over every pound, or you're managing a six-figure portfolio, you'll probably outgrow Plum's automation quickly.
Yes. Plum is regulated by the Financial Conduct Authority. Saveable Limited (FRN 739214) is Plum's investment firm and acts as the Cash ISA manager. Plum Fintech Limited (FRN 836158) handles the Open Banking side as an Account Information Service Provider. The e-money piece runs through Modulr FS as an upstream FCA-authorised provider.
The protection on your money depends on the product. Cash sitting in the Easy Access Interest Pocket is held in trust with Investec Bank. Cash ISA money is spread across multiple partner banks, currently Citibank NA London Branch, Lloyds Bank, BBVA, and Qatar National Bank.
Both are eligible for FSCS protection up to £120,000 per person, per partner bank (the deposit protection limit rose from £85,000 to £120,000 on 1 December 2025). Investments held in a Stocks and Shares ISA, GIA, or SIPP are covered by the FSCS up to £85,000 per person, per firm, though the value of the underlying investments can go down as well as up.
The Open Banking connection used to monitor your spending is read-only. Plum can see your transactions but can't move money out of your main bank account without you confirming each request.
Plum is ideal for anyone who struggles to save consistently. If you've tried and failed to build a savings habit, the automatic savings feature does the hard work for you - most users don't even notice the small amounts being set aside.
It's particularly good for younger savers and those new to investing, with low minimum investments and a friendly interface. The free Basic plan offers genuine value, though power users may want to upgrade for higher interest rates and additional features. If you prefer hands-on control over every penny, Plum's automated approach might feel too hands-off.
Plum reads your income and spending each week and automatically shifts small amounts you can afford into your savings, so a pot builds without you having to think about it.
Every card transaction gets rounded up to the nearest pound and the spare change tips into savings. Spend £2.40 on a coffee, 60p goes in.
Park spare cash in pockets earning interest (3.00% AER on the free Basic plan rising to 3.63% AER on Max as of May 2026), with no fixed term and instant withdrawals.
Invest from £2 in a curated set of funds or from £1 in individual shares (over 3,000 to choose from), across a tax-free ISA, a general account, or a self-invested pension.
Money in the Easy Access Pocket and Cash ISA is eligible for FSCS protection up to £120,000 per person, per partner bank, the same protection you'd get with a high-street bank.
I've come away thinking Plum is one of the most useful free apps you can have on your phone if you struggle to save manually. Over two million people use it, ratings are consistently strong (4.7 on iOS, 4.6 on Android), and the auto-saver genuinely moves cash into your pocket without you having to think about it. The trick it pulls off is doing the boring bit of saving so you don't have to.
The free Basic plan is generous: auto-savings, round-ups, the Cash ISA with no fees, and a starter Easy Access Pocket are all included without paying a penny. The paid tiers (Plus £3.99, Boost £7.99, and Max £14.99 a month as of May 2026) bump up the interest rate and lower the investment fees, but most casual users won't need them.
Where Plum is less compelling is if you're a confident DIY investor with a bigger pot. Once your investments grow beyond a few thousand pounds, the platform fee on the cheaper tiers starts adding up, and you'd save money moving the investment piece to a lower-cost broker. For everyone else who just wants a quiet, friendly app that nudges cash into savings each week, Plum delivers.
