Business Savings Accounts Explained (2026): How They Work

A business savings account earns interest on surplus cash. Among the providers we compare, fixed bonds reach 4.60% AER (Cambridge & Counties Bank) and the best unconditional instant-access rate is 3.90% AER (Cynergy Bank); conditional accounts can pay more. On £50,000 that’s roughly £1,950 a year that many business current accounts won’t pay.

If £50,000 of surplus cash is sitting in a current account paying no interest, that is roughly £1,950 a year less than the best instant-access rate in August 2026 (3.90% AER). We’ve reviewed every major UK business savings provider to help you pick the right account type and rate.

What Is a Business Savings Account?

A business savings account holds surplus cash your business wants to earn interest on without taking investment risk. Your money stays in a UK-authorised bank, earns a stated rate, and is FSCS-protected up to £120,000 per banking licence.

It is separate from your business current account. The interest your limited company earns is a taxable receipt under Corporation Tax, not personal income. There is no Personal Savings Allowance for limited companies.

Most business savings accounts require an existing business current account to fund them. Recognise Bank and Cynergy Bank accept funding from any UK business current account. Monzo Business savings are only available if you already bank with Monzo. Check the funding requirement before you apply.

£40,000 left idle in a current account for 9 months earns nothing. At Cynergy Bank’s 3.90% AER that same balance would have earned roughly £1,170 (£40,000 × 3.90% × 9/12, flat balance). That is money forgone.

Types of Business Savings Account

Three account structures exist. The right one depends on when you might need your money. We rate instant access as the sensible default for most businesses, and reach for notice or fixed only with cash we can genuinely commit.

Account type Access Rate range (August 2026) Best for
Instant access Withdraw any time 3.33%–3.90% AER VAT reserves, working capital buffer
Notice account 35–180 days notice 3.55%–4.00% AER Quarterly reserves, tax provisions
Fixed-term bond No access until maturity 3.90%–4.60% AER Committed retained profit, future capital spend
Rates from Cynergy Bank, Allica Bank, Recognise Bank, Redwood Bank, Cambridge & Counties Bank, Capital on Tap, August 2026. Variable rates can change. Capital on Tap Instant Savings: 3.82% AER (variable) for new customers includes a 0.59% bonus which reduces after 60 days; applicable for deposits up to £1 million.

Instant Access Accounts

Instant access accounts let you deposit and withdraw at any time. Best rates in August 2026: Cynergy Bank at 3.90% AER (£10,000 minimum) and Allica Bank at up to 4.08% AER (conditional on a CASS bank switch). Capital on Tap Instant Savings pays 3.82% AER (variable) for new customers for the first 60 days (a 0.59% bonus), then reverts to 3.23% AER ongoing, on deposits up to £1 million. That 3.82% is not a like-for-like headline: the 0.59-point bonus lasts 60 days, after which the account earns 3.23%, below Cynergy’s unconditional 3.90%. Note that Tide and Capital on Tap savings both sit under the ClearBank banking licence, so the combined FSCS cover across both is £120,000, not £240,000. Our easy-access business savings page tracks the current deals.

If your VAT quarter is due in 6 weeks and you might need those funds early, instant access removes the uncertainty. The rate is lower than notice or fixed. You are paying for the flexibility to withdraw without notice.

Notice Accounts

Notice accounts require you to submit a withdrawal notice and wait. Common notice periods: 35 days, 95 days, 120 days, 180 days. Early withdrawal from a notice account often incurs significant penalties, not simply a refusal of access. The British Business Bank confirms this is a standard feature of notice account terms: check the penalty structure before committing. See current rates on our business notice accounts page.

If your payroll run is in 30 days and your savings are in a 95-day notice account, you cannot access those funds in time. Plan notice periods around your cash flow decision cycle.

Notice accounts work well for reserves with a predictable withdrawal date: a VAT bill in 3 months, a capital equipment purchase in 6 months. You accept the notice period in exchange for a higher rate.

Fixed-Term Bonds

Fixed-term bonds lock your money for a set period: typically 6 months, 1 year, or 2 years. No early access. In return, the rate is locked for the full term. Our business bonds page carries the current terms and rates.

Cambridge & Counties Bank pays 4.60% AER (fixed) on both its 1-year and 2-year fixed business bonds (Issue 100 and Issue 57), with a £20,000 minimum deposit. Recognise Bank pays 4.30% AER on its 2-year fixed bond (£1,000 minimum), making it the better entry-level option for smaller deposits.

Fixed bonds suit committed capital: retained profit held for a future spend, or reserves your accountant confirms won’t be touched until the next financial year.

How Interest Is Calculated and Paid

The advertised rate is the AER, or Annual Equivalent Rate. It reflects the true annual return, accounting for compounding. The gross rate is the stated rate before compounding. For most business savings accounts paying monthly or annually, AER and gross rate are close. For comparing accounts, AER is the figure to use: it already folds in how often interest is paid, so a monthly-paying account and an annual one can be judged on the same basis.

Monthly vs Annual Interest

Some providers let you choose monthly or annual interest payments at account opening. Monthly suits businesses that want a visible interest line each month or organisations reporting income to a board quarterly. Annual suits businesses that want a single interest credit at year-end. Monthly interest does not mean a better return; the AER is what you compare. The choice is about when the money lands and how it shows in your accounts, not how much you earn.

Minimum Balance Rules

Some providers apply a minimum balance floor: if your balance drops below the threshold, you earn no interest. Redwood Bank earns no interest if your balance drops below £10,000. This is not a fee. Check whether the provider’s minimum applies only when you open the account or must be maintained to keep earning interest. If your balance is likely to dip, this condition can matter more than a small difference in headline rate: a fraction of a percentage point is worth nothing in a month where you earn no interest at all.

FSCS Protection for Business Savings Accounts

The FSCS (Financial Services Compensation Scheme) protects eligible deposits up to £120,000 per eligible depositor, per authorised firm (often described loosely as “per banking licence”). If a UK-authorised bank fails, the FSCS pays out up to £120,000 per firm.

Eligibility does not depend on your company size. The FSCS protects a company’s deposits regardless of turnover or balance sheet, and there is no size test. What matters is the depositor type: most businesses are covered, but authorised financial-sector firms (such as banks, investment firms and insurers) and most public authorities are not.

Limited Company vs Sole Trader Protection

Whether your business gets its own £120,000 separate from your personal savings comes down to one thing: is the business a separate legal entity?

Business structure Business deposits protected separately from the owner’s personal savings?
Limited company Yes. The company claims up to £120,000 for its account, and you separately claim up to £120,000 on a personal account at the same bank.
LLP Yes. Treated the same as a limited company.
Sole trader No. Your business and personal accounts are aggregated into one £120,000 limit.
Ordinary partnership One £120,000 limit for the business account, not one per partner.

Every figure is per authorised firm. Source: FSCS.

Once you are putting £200,000 into savings, this stops being theoretical: which banks actually hold the money decides how much sits inside FSCS protection. Which providers share a banking licence now drives how you split the cash.

ClearBank shared licence

Several popular providers, including Tide savings and Capital on Tap savings, hold deposits with ClearBank. The FSCS limit is per banking licence, not per provider. If you have savings with Tide and Capital on Tap, they share one £120,000 FSCS envelope. Your combined deposits across all ClearBank-backed providers are covered up to £120,000 in total.

FSCS Stacking Strategy

If keeping every eligible deposit inside FSCS cover is a priority, we recommend keeping no more than £120,000 with any single authorised firm, and spreading larger balances across two or more independently authorised banks. Cynergy Bank, Recognise Bank, Redwood Bank, and Aldermore each hold independent banking licences, with separate FSCS envelopes from each other and from ClearBank. Two accounts at two independently licenced banks gives £240,000 of FSCS cover.

Tax on Business Savings Interest

Interest earned by a UK limited company is a taxable receipt subject to Corporation Tax. It forms part of your company’s taxable profits and is declared in your Company Tax Return. There is no equivalent of the Personal Savings Allowance for limited companies.

For most sole traders, interest on a business savings account is taxed as personal savings income, not trading profit, so it falls under your personal savings allowance rather than being added to your trading profits. HMRC only treats it as trading income in limited cases: broadly, where the deposit is short-term, integral to how the trade operates and part of your working capital (HMRC manual BIM40805). Interest on an ordinary business current account, within normal banking needs, is trading income. Take advice where the amounts are material.

In practice there is usually little extra admin. The interest lands in your savings account and shows on your statements, so include those with the records you give your accountant at year-end. Do not confuse it with personal savings interest, which has a separate £500–£1,000 Personal Savings Allowance.

Business Savings vs Business Current Account

A business current account handles daily operations: incoming payments, outgoing invoices, payroll, supplier payments. Most business current accounts pay little or no interest.

A business savings account holds surplus cash you don’t need this week. The question is: what’s the minimum you need liquid at all times?

How much to keep liquid depends on your commitments, not a single rule. Map what you owe and when: payroll, VAT, Corporation Tax, supplier payments, loan repayments and a buffer for seasonal dips. Whatever is left after those is the surplus that can move to savings. A business with steady costs might keep two to three months of outgoings accessible; one with lumpy or seasonal cash flow needs more.

On £50,000 at 3.90% AER, you earn £1,950 per year that many business current accounts won’t pay. That’s the opportunity cost of leaving cash idle.

How to Choose the Right Business Savings Account

Four questions to narrow the choice:

Question If yes If no / unsure
Do you need instant access? Cynergy Bank (3.90% AER) or Allica Bank (up to 4.08% AER) Notice or fixed-term for a higher rate
Can you commit for 12+ months? 1–2 year fixed bond: Cambridge & Counties Bank at 4.60% AER (£20,000 min); Recognise Bank at 4.30% AER (£1,000 min) Notice account or instant access
Is your minimum deposit under £10,000? Recognise Bank (£1,000 min): best fixed-term option Cynergy and Redwood require £10,000+; Aldermore takes £1,000
Is your organisation a charity or council? Redwood Bank explicitly supports non-commercial organisations Most challenger savings banks focus on SMEs only
August 2026 data.

For most businesses in August 2026, we rate Cynergy Bank best for unconditional instant access (3.90% AER, £10,000 min) and Recognise Bank best for fixed-term savings (4.30% AER, £1,000 min). If you can commit £20,000 or more, Cambridge & Counties Bank’s 4.60% AER fixed bond is one of the strongest business bonds, though Union Bank of India (UK) currently lists 4.76% on a 1-year GBP business bond.

Key Exclusions and Restrictions for Business Savings Accounts

Not every business qualifies for every savings account. We have verified the following exclusions and restrictions across multiple providers’ eligibility terms.

Excluded Business Types

Several categories of organisation are explicitly excluded from business savings accounts at UK providers. Nationwide’s published eligibility terms, for example, list the following as ineligible: banks and building societies, insurance companies, corporate trusts, borough councils, cash or liquidity funds, company pensions, friendly societies, life policies, investment and unit trusts, and government or political parties. Most ordinary trading SMEs will not appear on a list like this. It is still worth a look before you compare rates, because checking eligibility first saves a wasted application.

If your business falls into any of these categories, check directly with each provider before applying. Eligibility criteria vary by bank, and some specialist providers exist for professional services and regulated sectors.

Client Saver Accounts for Regulated Businesses

Regulated businesses such as solicitors and law firms can access designated Client Saver accounts designed for client money held in trust. Santander UK offers an Undesignated Client Saver for regulated businesses involved in financial and property transactions. However, banks retain the right to refuse any application for a Client Saver account at their discretion, regardless of the applicant’s regulatory status. If you hold money on behalf of clients, this matters: an ordinary business savings account is the wrong product for client funds, and the bank can still decline even when you qualify.

Challenger Bank Limitations

Challenger banks typically offer competitive savings rates but may have limited facilities for cash and cheque handling, and fewer options for complex lending compared with established high street banks. If you only need somewhere to hold surplus cash, those limits may not matter. If you also deposit cash or cheques, or want an overdraft or a loan from the same bank, they matter a great deal.

Best Business Savings Accounts (August 2026)

Based on our reviews, here are the strongest picks across the three account types. All rates verified 13 August 2026. The right pick depends less on the top rate than on what you can accept alongside it: a minimum deposit, a notice period, or a switching condition.

Recognise Bank Fixed-term (2-year) 4.30% AER £1,000 Best fixed rate for smaller deposits
Cambridge & Counties Bank Fixed-term (1 or 2-year) 4.60% AER £20,000 Highest fixed rate in our table; larger deposits
Rates as at August 2026. Variable rates can change. Fixed rates locked for the term. FSCS protection to £120,000 per banking licence. Allica Bank top rate requires a CASS bank switch and 15 outbound transfers/month.

Frequently Asked Questions

  • Do I need a business bank account to open a business savings account?

    Usually, yes. Most providers require you to fund the savings account from a business current account. Recognise Bank and Cynergy Bank accept any UK business current account. Monzo Business savings are only available to existing Monzo Business customers. Check the funding requirement before applying.

  • Is interest on a business savings account taxable?

    Yes. For a UK limited company, savings interest is a taxable receipt subject to Corporation Tax. Declare it in your Company Tax Return. There is no Personal Savings Allowance for limited companies. For most sole traders, the interest is taxed as personal savings income under your personal savings allowance, not as trading profit, unless the deposit is integral to the trade.

  • What is the FSCS limit for a business savings account?

    FSCS protects eligible deposits up to £120,000 per eligible depositor per banking licence. Most businesses are eligible regardless of size, with authorised financial firms the main exception. If you use multiple providers sharing the same banking licence (e.g. ClearBank), the £120,000 limit applies to your combined deposits across all of them.

  • What is the highest interest rate on a business savings account?

    In August 2026, the highest fixed rate among the providers we compare is 4.60% AER from Cambridge & Counties Bank on its 1-year and 2-year fixed business bonds (£20,000 minimum). For smaller deposits, Recognise Bank pays 4.30% AER on a 2-year fixed bond (£1,000 minimum). For instant access, Cynergy Bank pays 3.90% AER (£10,000 minimum) with no conditions. Rates change: verify before opening.

  • Can I access my money in a notice account early?

    Usually not. Most notice accounts require you to serve the full notice period, and some providers charge a penalty for early access rather than allowing it; a few have exceptional provisions, so check the individual account terms. If you are not certain you can wait 35–180 days, an instant access account is the safer choice.

How we assess value: BusinessExpert defines overall value for savings accounts by assessing the highest effective AER alongside the restrictions attached to it, such as minimum deposit, notice period, and access conditions. A headline rate with a £20,000 minimum is not the same value proposition as 4.30% AER with a £1,000 minimum. We note where conditions apply.

Rate accuracy: Variable rates can change at any time. We checked figures at the date shown above. BusinessExpert recommends reassessing your savings account at least annually and actively considering switching providers when rates change materially, particularly when Bank of England base rate decisions shift the market.
