Offer overviewChris · Your personal guide
Plum is a money management app that saves and invests for you automatically.
£15 free cash through TopCashback for signing up to Plum and connecting your bank account. No card transactions needed. A small Direct Debit deposit activates the account, mine was £5.15, and you can withdraw it once the cashback arrives.
The cashback shows in TopCashback within about a week, then turns payable once Plum confirms it. If you keep Plum afterwards, the automatic saving rules are the useful bit: it reads your spending and moves small amounts across without you noticing.

Quick review
Plum
Wondering whether Plum is worth it beyond the bonus? Here is our honest take.
Plum is an FCA-regulated UK savings and investing app that nudges spare cash into a pot every week. You also get round-ups, an Easy Access Pocket with FSCS protection, and a stocks and shares ISA from £1. Quidsy has a free cash offer for new signups. Handy if saving by hand never quite happens. Paid plans cost extra.

Chris' verdictYour personal guide, QuidsyI'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.
Saveable Limited is authorised and regulated by the Financial Conduct Authority (FRN 739214). Deposits held with Plum's partner banks via the Easy Access Pocket and Cash ISA are eligible for FSCS protection up to £120,000 per person, per bank. Investments held in a GIA, Stocks and Shares ISA, or SIPP are covered by the FSCS up to £85,000 per person. The value of investments can go down as well as up.
