A business savings account holds surplus company cash separately from your everyday current account, earning interest at an AER (annual equivalent rate) instead of sitting idle where it earns little or nothing.
Businesses commonly use savings accounts to set aside money earmarked for VAT, corporation tax or payroll, as well as to earn a return on cash reserves not needed for immediate trading.
Rates and access vary between easy-access accounts you can dip into anytime and fixed-term deposits that lock funds away for a set period in exchange for a higher guaranteed rate.
You open the account alongside or separately from your main business current account, transferring surplus funds in whenever cash flow allows, and interest accrues daily and is typically paid monthly or at maturity.
Easy-access accounts allow withdrawals anytime, though rates can move with the base rate, while fixed-term bonds guarantee a rate for the whole term but usually restrict or penalise early withdrawal.
Easy access is usually essential, since you need funds available on the exact payment date regardless of notice periods.
A fixed-term deposit typically pays a noticeably better rate in exchange for locking the funds away.
A notice account can bridge the gap, offering a better rate than easy access provided you can plan withdrawals in advance.

| Account type | Typical AER | Access | Notice |
|---|---|---|---|
| Easy access | 2.00% – 3.50% | Instant | None |
| 32 – 95 day notice | 3.25% – 4.25% | On notice | 32 to 95 days |
| 1 year fixed term | 3.75% – 4.50% | At maturity | Locked |
| 2 year fixed term | 3.60% – 4.35% | At maturity | Locked |

Most business current accounts pay nothing at all, so idle reserves quietly lose value to inflation every month.
“Split reserves across easy access and notice accounts — you keep working capital liquid and still earn a proper rate.”
Look past the headline offer and check these five things:
Some providers bundle a fixed number of free transactions each month, then charge per payment or cash deposit above that — model your real volumes before you commit.
Check native links to Xero, QuickBooks or Sage, since manual reconciliation quickly eats into any time saved by switching provider.
Digital-only providers are usually cheapest but can charge heavily, or refuse outright, to pay in cash or cheques through the Post Office or a partner network.
Compare whether you get a dedicated relationship manager, phone support, or app-only chat — this matters far more once something goes wrong with a payment.
Confirm whether the provider holds a full UK banking licence (FSCS protection up to £85,000) or is an e-money institution using client-money safeguarding rules instead.

Requirements are generally straightforward, but expect:
A limited company, LLP, partnership or sole trader with standard business verification documents.
Many providers require you to already hold, or open, a business current account with them or elsewhere as a funding source.
Fixed-term business accounts commonly require a minimum deposit of £1,000 to £10,000, higher than typical personal savings minimums.
The same identity and address checks required for opening a business current account.
The agency sets aside 20% of every invoice paid into a separate easy-access business savings account earmarked for its upcoming corporation tax bill.
Over eight months, the reserved £48,000 earns roughly £1,300 in interest at 4.3% AER, rather than sitting in a non-interest-bearing current account.
Because it's easy access, the funds remain available immediately when the tax payment is due, with no penalty for withdrawal.
If your business carries expensive borrowing, such as a credit card balance or high-interest loan, paying that down usually beats the interest earned on a savings account, since borrowing rates are almost always higher than savings rates.
Once expensive debt is cleared, a savings account is the sensible home for tax reserves and a cash buffer covering at least a few months of core costs.
Longer-term surplus cash beyond that buffer might also be considered for investment, though that carries capital risk a savings account doesn't.

Withdraw funds anytime without penalty, ideal for tax reserves and short-term cash buffers. Rates are typically a little lower than fixed-term equivalents.
Locks funds away for a set term, commonly three months to two years, for a guaranteed higher rate. Best for cash you're confident won't be needed before the term ends.
Requires 30 to 190 days' notice before withdrawal, sitting between easy access and fixed terms on rate and flexibility. Useful for planned expenses like an upcoming tax bill or equipment purchase.

“We moved our VAT reserve into a 95-day notice account and it now earns more than four grand a year doing nothing.”
