Business Savings Accounts Explained (2026): How They Work
A business savings account earns interest on surplus cash. The best fixed rates in July 2026 reach 4.60% AER (Cambridge & Counties Bank); instant access rates run from 3.82% to 3.90% AER. On £50,000 that’s £1,950+ per year a current account won’t earn.
- Allica Bank pays up to 4.08% AER, the highest affiliate rate we’ve reviewed.
- FSCS-protected under Allica’s independent banking licence (not ClearBank).
- Available to UK SMEs; conditional on a CASS bank switch for the top rate.
If your business has surplus cash sitting in a current account, you’re losing at least £1,950 per year on a £50,000 balance compared with the best instant access rate in May 2026. 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.
Your accountant at year-end reviews the cash position and flags that £40,000 has sat idle in the current account for 9 months. A business savings account would have earned roughly £1,560 in that time at Cynergy Bank’s 3.90% AER. That is money now gone.
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 (May 2026) | Best for |
|---|---|---|---|
| Instant access | Withdraw any time | 3.33%–3.90% AER | VAT reserves, working capital buffer |
| Notice account | 35–180 days notice | 3.80%–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 |
Instant Access Accounts
Instant access accounts let you deposit and withdraw at any time. Best rates in July 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, including a 0.59% bonus that reduces after 60 days, on deposits up to £1 million. 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.
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.
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. The notice period discipline is the cost of 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.
Cambridge & Counties Bank pays 4.60% AER (fixed) on both its 1-year and 2-year fixed business bonds (Issue 100 and Issue 57, confirmed against ccbank.co.uk on 20 July 2026), 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.
Monthly vs Annual Interest
Most providers let you choose monthly or annual interest payment 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.
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. Treat minimum deposit requirements as ongoing balance requirements, not just opening thresholds.
FSCS Protection for Business Savings Accounts
FSCS (Financial Services Compensation Scheme) protects eligible deposits up to £120,000 per eligible depositor per banking licence. If a UK-authorised bank fails, FSCS pays out up to £120,000 per licence.
For business deposits, eligibility depends on your company size. Small companies (under £10.2m turnover or £5.1m balance sheet) are typically eligible. Verify at fscs.org.uk before depositing large sums.
Once you are moving £200,000 into savings, the FSCS stacking question turns operational. At quarter-end, a finance director weighing that decision needs to know which providers share a licence before splitting 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
We would not leave more than £120,000 with any single banking licence. Businesses with over £120,000 in savings should spread across at least two independently licenced 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 sole traders, interest from a business savings account is business income and appears on your Self Assessment. The applicable allowance depends on your personal circumstances; consult your accountant.
Practically: the bank credits interest to your savings account. It appears in your statements. Pass this to your accountant with your year-end accounts. 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?
A practical split: keep 2–3 months of operating costs in your current account, move the rest to savings. If your monthly costs are £20,000, keep £40,000–£60,000 liquid. We think anything beyond that buffer is just lost interest.
On £50,000 at 3.90% AER, you earn £1,950 per year that a current account 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, Redwood, Aldermore all require £10,000+ |
| Is your organisation a charity or council? | Redwood Bank explicitly supports non-commercial organisations | Most challenger savings banks focus on SMEs only |
For most businesses in July 2026, we’d start with Cynergy Bank for unconditional instant access (3.90% AER, £10,000 min) or Recognise Bank 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 now the market-leading rate. Compare all providers at our best business savings accounts page.
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.
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.
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 your business regularly handles cash or needs overdraft or loan facilities alongside savings, weigh up whether a challenger bank covers all your needs before switching.
Personal Guarantees (Business Credit Facilities)
A personal guarantee (PG) creates personal liability for a business debt: if the business cannot repay, the director or owner becomes personally responsible. Personal guarantees are a standard feature of small business lending and credit facilities, not savings accounts. They are relevant here because some integrated providers, including Capital on Tap, offer both savings and credit products: the savings account carries no personal guarantee, but the linked business credit card requires one. Understand which product each term applies to before signing.

Frequently Asked Questions
Do I need a business bank account to open a business savings account?
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 sole traders, it goes on your Self Assessment as business income.
What is the FSCS limit for a business savings account?
FSCS protects eligible deposits up to £120,000 per eligible depositor per banking licence. Business FSCS eligibility is based on company size, verify at fscs.org.uk.

What is the highest interest rate on a business savings account?
In July 2026, the highest fixed rate is 4.60% AER from Cambridge & Counties Bank on its 1-year and 2-year fixed business bonds (£20,000 minimum, verified against ccbank.co.uk on 20 July 2026).

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.
