Best business savings account 2026

What is a business savings account and how does it work?

A business savings account is a deposit account, separate from your everyday business current account, that pays interest on funds a company does not need for immediate spending. You transfer surplus cash from your current account into the savings account, the provider pays interest expressed as an Annual Equivalent Rate (AER), and the balance remains available according to whichever access rules apply: instant, notice, or fixed term.

Most UK business savings accounts are opened and managed entirely online or through an app, often by a challenger bank or a specialist savings provider rather than a traditional high street branch. Interest is usually calculated daily and paid monthly or annually, and it can either build up inside the savings account or sweep automatically back to your linked current account, depending on the provider.

Business savings accounts are generally only open to UK-registered limited companies, limited liability partnerships or sole traders, and providers will typically ask for your Companies House registration number, details of directors and beneficial owners, and confirmation of your trading activity before an account can be opened.

Easy access, notice accounts and fixed-term deposits: which suits your business?

UK business savings products fall into three broad categories, each trading flexibility against rate.

Easy access accounts let you deposit and withdraw whenever you need to, with no notice period, which suits an operating buffer or funds you might need for a VAT or payroll payment at short notice. The trade-off is a variable rate that the provider can change, and it is usually the lowest rate of the three categories once any introductory bonus has ended.

Notice accounts require you to give advance warning, commonly 30, 60 or 95 days, before withdrawing without losing interest. In exchange for that reduced flexibility, notice accounts typically pay a meaningfully higher rate than easy access, making them a reasonable middle ground for cash you are fairly confident you will not need imminently.

Fixed-term deposits lock your funds away completely for an agreed period, often between three months and two years for business products, and pay a guaranteed rate for the full term. They generally offer the highest headline rate but the least flexibility, so they suit money you are certain your business will not need before the term ends.

Many businesses split surplus cash across categories: an easy access buffer for near-term obligations, and notice or fixed-term deposits for genuinely spare funds.

How much of the FSCS's £120,000 protection actually covers your business

Eligible deposits held with a UK bank or building society authorised by the Prudential Regulation Authority are protected by the Financial Services Compensation Scheme up to £120,000 per eligible depositor, per banking licence. This limit rose from £85,000 on 1 December 2025, so figures you see quoted as £85,000 elsewhere are now out of date.

If your business trades as a limited company, it is a separate legal entity from you personally, so a business account gets its own £120,000 limit in addition to any personal accounts you hold with the same bank. If you trade as a sole trader, you and your business are the same legal person, so personal and business balances held with the same bank are added together and count towards a single £120,000 limit.

Protection is per banking licence, not per brand: several providers share a licence with a parent bank or sister brand, so holding accounts with what look like different providers can still leave you covered under one combined limit. Businesses holding cash reserves above £120,000 commonly spread deposits across more than one FSCS-protected institution to keep the full amount covered.

Not every provider is a bank. Some fintechs, including Tide's savings product, are authorised as electronic money institutions and hold customer funds with a partner bank under a safeguarding arrangement rather than a banking licence. Safeguarding ring-fences your funds from the company's own money and offers real protection, but it is legally distinct from FSCS cover, so it is worth checking which arrangement applies before depositing significant sums.

Corporation tax on business savings interest

If you trade through a limited company, interest earned on business savings is treated as non-trading loan relationship income and forms part of your company's taxable profits, so it is taxed at your Corporation Tax rate rather than through a personal tax-free allowance. Companies with profits up to £50,000 pay the small profits rate of 19%, companies with profits above £250,000 pay the main rate of 25%, and profits in between are taxed on a sliding scale with marginal relief.

If you operate as a sole trader, your business and personal finances are not legally separate, so savings interest is treated as your personal savings income and taxed through Self Assessment, in the same way as an individual saver, including access to the Personal Savings Allowance and the starting rate for savings where applicable.

Interest earned by a limited company should be recorded through your normal management accounts and included in your Corporation Tax return; it is not tax-free simply because the cash originated from trading profits.

Sole trader vs limited company: does it change where you should save?

Because a sole trader and their business are the same legal person, there is no legal requirement to use a dedicated business savings product, and some sole traders simply use a personal easy access account or cash ISA for surplus trading income. A limited company, by contrast, cannot generally hold funds in a personal savings account, since the money legally belongs to the company rather than to a director personally.

Even where it is not required, keeping business and personal savings separate makes bookkeeping, VAT and tax return preparation and cash flow tracking considerably easier, and most accountants recommend a dedicated business account regardless of trading structure. A separate account also keeps your records cleaner if HMRC ever opens an enquiry into your business.

Introductory bonus rates: read the terms before you apply

Several of the highest headline rates on business easy access accounts include a fixed introductory bonus that applies only for a set period, commonly the first three to twelve months. Once that period ends, the rate typically drops to a noticeably lower ongoing rate, sometimes by two percentage points or more.

Before opening an account for the headline figure, check the underlying rate that applies once any bonus expires, and set a reminder to review the account when that date approaches. Providers are required to notify you of rate changes, but few businesses actively switch on receipt of that notice, so a calendar reminder is the more reliable safeguard against quietly earning a below-market rate.

How to open a business savings account in the UK

Opening a UK business savings account online typically takes between 10 and 20 minutes once you have the necessary details to hand. You will usually need your company's Companies House registration number if you are a limited company, details and identification for directors and any beneficial owners holding 25% or more of the business, and confirmation of your registered trading address.

Most providers also carry out standard know-your-business and anti-money-laundering checks before an account can be activated, and several require you to already hold, or to open alongside, a business current account with the same provider or wider banking group. Once verified, you fund the account by transferring from your business current account, and Faster Payments transfers typically clear the same or next working day.

Common mistakes businesses make with surplus cash

The most frequent mistake is leaving substantial balances sitting in a non-interest-bearing current account out of inertia, effectively losing value to inflation for no benefit in flexibility. A second common error is chasing the highest headline rate without checking whether it includes a temporary bonus, only to find the ongoing rate is considerably lower once the introductory period ends.

Businesses also sometimes overlook the FSCS limit entirely, concentrating large reserves with a single provider and leaving anything above £120,000 unprotected in the event of a provider failure. Finally, some companies lock cash into a fixed-term deposit without keeping enough in easy access to cover predictable near-term outgoings such as VAT, payroll or corporation tax instalments, then face an early-withdrawal penalty when a bill arrives sooner than expected.
