Best Business Savings Accounts UK

Should a small business have a savings account?

Usually, yes, once there is genuinely spare cash in the business. A separate savings account can give money that would otherwise sit idle a job to do, while also helping you ring-fence tax, emergency reserves and money for planned spending.

There is a catch. The best savings rate in Britain is no use if you have locked away the VAT money three days before HMRC wants it.

For most owner-managed businesses, the sensible order is:

1. keep enough in the business current account for normal bills;
2. keep an emergency buffer somewhere accessible;
3. separate money you know you will owe for tax;
4. only then consider locking genuinely surplus cash for a better rate.

What would a better savings rate actually earn?

Percentages are abstract. Pounds are easier.

Using Shawbrook’s current 3.86% easy-access rate as a simple illustration, and assuming the rate stayed unchanged for a full year:

For a tiny business, £386 might cover a software subscription or a few months of insurance. At £50,000, nearly £2,000 is no longer loose change.

The point is not to chase every 0.05% rate movement. It is to notice when tens of thousands of pounds have been sitting in a current account earning nothing for months.

An interesting benchmark: how much do other businesses actually save?

Tide’s 2026 Business Benchmark Index, based on thousands of businesses in its data, found that first-year businesses held an average of £10,973 in savings.

That average rose to £26,249 for businesses aged two to five years, £38,187 at five to ten years and £56,864 for businesses more than a decade old.

It is not a target and it is not a rule. A software consultancy and a restaurant need completely different cash buffers. But it is a useful reminder that building a reserve tends to become more important as a business matures.

There were around 5.69 million UK private-sector businesses at the start of 2025, and 5.64 million of them were small businesses with fewer than 50 employees. Around three quarters had no employees other than their owners. In other words, most UK businesses do not have a finance department watching cash balances every morning. The owner has to do it.

Easy access, notice or fixed: which is right for your business?

Easy access: for money you may actually need

This is where we would normally keep the emergency fund, a large upcoming VAT bill or money earmarked for stock.

You give up some interest compared with the best fixed deals, but you keep control. That matters when a customer pays late, a van breaks down or a supplier suddenly wants payment upfront.

Notice account: for money with a likely date attached

A notice account works when you are fairly sure the money is not needed immediately but do not want to lock it away for a whole year.

For example, a business planning a refit in six months could put part of the budget into a 95-day account and give notice well before the spending date.

Fixed rate: for genuinely surplus cash

Fixed accounts usually offer certainty and potentially a better rate, but this is not where we would put payroll, VAT or the emergency reserve.

If £30,000 is definitely not needed for 12 months, a fixed bond can make sense. If that sentence makes you slightly nervous, use easy access instead.

Why business savings rates are moving

The Bank of England’s current Bank Rate is 3.75%, and the next scheduled decision is 17 September 2026.

Variable savings rates can move when Bank Rate moves. Fixed accounts behave differently because you lock the rate at the point you open them.

That is why this page should be treated as a shortlist rather than a permanent league table. Check the live rate immediately before applying.

Tide Instant Saver: best when banking and savings sit together

Tide’s Instant Saver currently offers new members an introductory rate of up to 4% AER variable for the first four months. The rate is tiered, so the headline 4% does not necessarily apply to every pound in the account.

After the introductory period, the rate follows the Tide plan. Current published rates are 2% on Free, 2.5% on Smart, 3% on Pro and 3.25% on Max, subject to the relevant balance limits and terms.

The main attraction is convenience. If your Tide Business Account already handles day-to-day banking, moving spare cash into a linked saver takes very little effort.

Tide says Instant Saver starts from £1, has no withdrawal penalties and pays interest monthly. Eligible deposits with ClearBank can also receive FSCS protection up to £120,000 across the relevant ClearBank accounts, subject to scheme rules.

Shawbrook Easy Access: strongest pure easy-access rate on our shortlist

Shawbrook’s current Easy Access Business Account pays 3.86% AER variable, with a £1,000 minimum balance and next-working-day access.

That is a strong combination for a business reserve: the money is earning a meaningful rate without being locked for months.

The important operational detail is “next working day”. If you may need the cash instantly on a Sunday, an instant-access saver inside your main banking app can still be more convenient.

Aldermore 95-Day Notice: a useful middle ground

Aldermore’s current 95-Day Notice account pays 4.00% AER variable with a £1,000 minimum opening balance.

Think of it as the account for money with a future job, but not an urgent one. A planned tax payment several months away, equipment purchase or premises refit may fit better here than in a one-year bond.

Shawbrook 1-Year Fixed: highest rate in this shortlist

Shawbrook currently lists a 4.70% AER fixed one-year Business Bond.

At £50,000, 4.70% equates to roughly £2,350 over a year before considering the business’s tax position.

The trade-off is obvious: you cannot treat a fixed bond like an emergency fund. Only lock cash that the business can genuinely live without for the full term.

Monzo Business Savings Pot: convenience over rate chasing

Monzo currently advertises up to 3.25% AER variable on its Business Instant Access Savings Pot, with no minimum deposit.

The rate may not beat every standalone savings provider, but if your Monzo Business Account is already the centre of the business, there is real value in being able to move money between pots instantly without another login.

How much should a small business keep in savings?

There is no magic percentage because a consultancy with £2,000 of monthly overheads is not the same business as a restaurant with payroll, rent, stock and energy bills.

A better approach is to build the savings pots around real commitments:

• Tax pot: money already mentally spent on Corporation Tax, VAT or Self Assessment.
• Emergency reserve: enough to absorb a bad month, broken equipment or a late-paying customer.
• Planned spending: equipment, recruitment, marketing or premises costs with a known date.
• True surplus: money the business can afford to lock away for longer.

If your bookkeeping still makes it hard to tell what cash is actually available, fix that before rate shopping. Our accounting software guide can help.

What about tax on business savings interest?

Business savings interest is generally paid gross, but that does not mean it is automatically tax-free.

For a limited company, interest normally forms part of the company’s taxable income. Sole traders can have different tax treatment depending on how the account and business are structured.

This is one area where your accountant should win the argument over a comparison website. We can compare the accounts; they know your tax position.

FSCS protection: the £120,000 point matters

The standard FSCS deposit protection limit increased to £120,000 from 1 December 2025 for eligible deposits with a UK-authorised institution.

The key word is institution, not account. If two savings brands operate under the same banking licence, the protection can be shared across them.

Businesses holding more than £120,000 of cash should check the underlying banking licences carefully and consider whether spreading deposits makes sense.

Business savings vs leaving cash in your current account

The case for moving spare cash gets stronger as the balance grows.

If £5,000 sits idle for a month, the missed interest is unlikely to change the business. If £100,000 has sat there for a year, it could be several thousand pounds.

That does not mean every pound should leave your current account. It means the current account should contain the money doing a current-account job.

If you are unhappy with the account itself, compare our best business bank accounts, free business bank accounts and startup business accounts.

What should you check before opening a business saver?

1. Access: instant, next working day, notice or fixed?
2. Minimum balance: what happens if you dip below it?
3. Rate type: variable, introductory or fixed?
4. Rate tiers: does the headline rate apply to the entire balance?
5. Eligibility: sole trader, partnership and limited-company rules differ.
6. FSCS: which bank actually holds the money?
7. Tax: how will the business account for the interest?
8. Existing banking: is a slightly lower rate worth it for instant movement between accounts?

Frequently asked questions

Our verdict

For most small businesses, the best place to start is an easy-access savings account, not the account with the absolute highest headline rate.

Shawbrook’s current 3.86% easy-access rate stands out if you want a competitive return without locking the cash for months. Tide is particularly convenient if you already use Tide for business banking, while Monzo offers the same sort of simplicity for existing Monzo users.

Once you have separated the money that must stay liquid, look at notice and fixed accounts for the rest. Aldermore’s 95-day account and Shawbrook’s one-year bond are much more interesting when you know exactly when the business will need the cash again.

The bigger lesson is simpler: know what your spare cash is for. Emergency money needs access. Tax money needs to be there on time. Truly surplus money can work harder.
