The savings pot idea is simple — the impact on behaviour isn't
Every digital bank worth its app store rating now offers some version of the same idea: instead of one savings account, you can create multiple labelled sub-accounts — called pots, spaces, vaults, jars, or goals depending on which bank you use — each holding money earmarked for a specific purpose. Monzo calls them Pots. Starling calls them Spaces. Chase UK calls them Savings Pots. Revolut calls them Vaults. The branding differs; the underlying principle is identical. You split your money mentally before you split it physically, and the act of naming a pot for something real — a holiday, a new boiler, a six-month emergency cushion — makes it meaningfully less likely you'll dip into it for a Saturday takeaway.
This is not a new idea in personal finance. The envelope budgeting method, which involves physically putting cash into labelled envelopes at the start of the month, was practised long before smartphones existed. What digital banks have done is remove the friction from the envelope system while keeping the psychological mechanism: money in a pot labelled "car insurance" does not feel the same as money floating in a general current account, even though it's all technically accessible. That small psychological distance reduces impulse spending in a way that a single current account, regardless of how much you intend to save from it, generally doesn't.
What different providers actually offer
Monzo allows you to create up to 20 Pots, name them, set a target balance, and optionally earn interest on them. Locked Pots let you set a date until which you cannot withdraw — useful if you're saving for something specific and don't trust yourself not to raid the pot. Monzo's Round Ups feature automatically moves the spare change from each card purchase into a designated Pot. On the interest side, Monzo has partnered with external providers to offer fixed and easy-access interest rates on certain Pots, though the rates change and you need to check current offerings in the app.
Starling Bank's Spaces work similarly but integrate tightly with the bank's Spending Insights, which shows you how much of your balance is genuinely spare once all your earmarked Spaces are excluded. Chase UK's Savings Pots earn a competitive easy-access rate with no strings attached — as of recent months, Chase has been one of the better-paying easy-access options among the major digital banks, though rates change with the Bank of England base rate. Revolut's Vaults can hold foreign currency as well as sterling, which is useful for travel savings.
Interest rates on pots — what to check and what to ignore
Some savings pots pay interest; others don't. The distinction matters if the pot holds a meaningful sum for more than a few weeks. A pot holding £3,000 earmarked for a bathroom renovation that won't happen for eight months should be earning interest during that period — not sitting at 0% while your current account provider benefits from your inertia.
When comparing interest rates on digital bank pots, watch for a few features of the small print. Introductory bonus rates that drop after three or six months are common; the headline rate you see at account opening isn't always the rate that applies to money left sitting for longer. Monthly compounding versus annual compounding matters less at typical savings sums but does affect the effective annual return. And some pots pay interest only up to a certain balance — Chase UK, for instance, caps its easy-access pot rate at £500,000, which isn't a constraint for most people but is worth knowing in principle.
If a pot's interest rate is 0% or close to it, and the money will sit there for months, consider whether a dedicated easy-access savings account from a separate provider would serve you better. Having multiple pots is convenient, but convenience shouldn't cost you a meaningful difference in return on balances over, say, £2,000.
Automatic savings rules — where pots genuinely earn their place
The most effective use of savings pots is in combination with automatic rules that move money without you having to think about it. Monzo and Starling both allow Round Ups, sweeping spare change into a pot with each purchase. Monzo also allows Salary Sorter, which automatically splits incoming pay into your current account and up to 20 pots the moment salary lands — before you have a chance to see the full balance and feel richer than you are.
This automation matters because the evidence on savings behaviour is fairly consistent: people save more when the default is to move money into savings and they have to opt out, rather than when the default is to leave money in a current account and they have to opt in. Setting up an automatic rule to move £200 into a holiday pot and £100 into an emergency fund pot the day after payday removes the weekly decision of whether to save. The money leaves before spending habits fill the gap.
FSCS protection — the question you should ask before using any savings feature
Money in a savings pot at a UK-regulated digital bank is covered by the Financial Services Compensation Scheme (FSCS) up to £85,000 per banking licence — exactly the same as any other UK bank. Monzo holds a UK banking licence. Starling holds a UK banking licence. Chase UK is a branch of JPMorgan Chase Bank, which carries its own FSCS protection. Revolut, until recently operating under a European e-money licence, now holds a UK banking licence following its 2024 grant, bringing it inside the FSCS umbrella for UK customers.
The one caveat worth knowing: if you bank with two providers that share a banking licence — for example, some building societies and partner banks operating under the same licence — the £85,000 limit applies to your combined holdings across both, not per account. Check the FSCS website to confirm whether any two banks you use share a licence before putting significant sums across both.
When pots work and when they're just admin
Savings pots are genuinely useful when the money in them has a purpose, a rough target, and a rough timeline. They are less useful as a permanent storage vehicle for large sums — that job is better handled by a cash ISA, a fixed-rate bond, or a dedicated high-interest easy-access account with competitive pricing. The pot structure excels at the medium-term, purpose-driven save: the car insurance renewal in four months, the Christmas budget, the house deposit growing over three years. For long-term wealth building, the structure matters less and the rate, the tax wrapper, and the time in market matter more.
