Moneybox savings rates — compare every account, plus switch offers and guides

Who they are

Moneybox was launched in 2016 by founders Ben Stanway and Charlie Mortimer as a mobile-first app. It made its name with a round-ups feature that helped people start saving with spare change, and has since brought saving, investing, home-buying, and retirement services together into one app. It is now the largest provider of Lifetime ISAs in the United Kingdom , and is used by over 1 million people across the UK.

The appeal is simple: everything sits in one clean interface, with automations - round-ups, payday boosts, regular deposits - that take the friction out of building a savings habit. There is no switching offer, so Moneybox competes purely on product and experience.

Savings accounts

Moneybox offers a solid spread of accounts, from instant access to fixed, all covered by FSCS protection up to £120,000.

The flagship Cash ISA pays 4.00% AER variable, which includes a 0.55% introductory boost for the first 12 months - the underlying base rate sits at 3.45%. You need a minimum of £500 to open it. If you want more withdrawal flexibility without a minimum balance requirement, the Open Access Cash ISA is available at 0.75% - a meaningful rate drop, so it is worth thinking about which suits your habits.

The Cash Lifetime ISA is where Moneybox really stands out. It currently pays 4.25% AER variable (a 1.45% boost on a 2.80% base rate) and requires just £1 to open. The government adds a 25% bonus on contributions of up to £4,000 per year - worth up to £1,000 free annually - though the standard LISA withdrawal penalty applies if you access the money outside of buying a first home or reaching age 60.

For non-ISA savers, the 32 Day Notice Account pays 3.77%, the 95 Day Notice 3.83%, and the 90 Day Notice 4.00%. The 1 Year Fixed Rate Bond comes in at 3.75% with no access until maturity. The Simple Saver easy-access account pays 2.40%, with access on the next working day and a limit of one withdrawal per month - though existing Moneybox customers holding a qualifying ISA, LISA, JISA, or pension can earn an additional 1% reward rate on top.

Things to bear in mind

The headline rates on the Cash ISA and Lifetime ISA both include a time-limited boost. Once that 12-month period ends, the rate drops back to the base. It is worth setting a calendar reminder at around 11 months so you have time to reassess before the boost expires rather than after.

The Moneybox Cash ISA is also non-flexible, meaning any withdrawals you make cannot be replaced within the same tax year without using more of your annual ISA allowance. The Open Access ISA removes that concern if unlimited withdrawals matter to you.

On LISA transfers, Moneybox accepts transfers in from other cash LISAs, but not from stocks and shares LISAs or other ISA types. If you are moving from a cash LISA elsewhere, that should not be a problem - but check before initiating anything.

Is it right for you?

Moneybox works well for people who want a polished, app-based savings experience with a wide product range in one place. It is particularly strong for first-time buyers building a deposit through a Lifetime ISA, and for savers who appreciate automated features over manual management.

If you need the very highest rate with no strings attached, always check the live comparisons - bonus periods and base rates shift regularly. The current figures for every Moneybox account are shown on this page and updated as soon as we are notified of a change.
