5 reasons every startup needs a business savings account

Starting a new business is exciting, but managing finances effectively can make or break a startup’s success.

According to researchers at QuickBooks, 47% of small business owners identify cash flow as a major issue. So, it’s hardly surprising that more than half of entrepreneurs say poor financial or resource management is holding their business back.

Does this sound familiar? Fortunately, if you’re struggling to manage your company’s finances, there are a few practical ways to make them more predictable and profitable. One of the most effective solutions is to set up a business savings account.

For startups managing tight budgets and cash flow spikes, separating funds can make financial decision-making far less stressful. Read on to explore five key business savings account benefits. We’ll also look at the different types of business savings accounts and walk you through opening a business savings account in the UK.

What is a business savings account?

Simply put, a business savings account is a bank account designed specifically to help businesses save money, gain interest, and manage cash reserves separately from their daily operating funds.

Unlike most business current accounts, business savings accounts typically offer interest on the balance you’ve deposited. This helps your money grow over time.

The level of interest you can accumulate from your balance depends on the type of access your business savings account provides. For example, some account types allow for immediate access, while others require advance notice or can’t be accessed for a fixed period.

Regardless of the type of account you set up or your access facility, all business savings accounts in the UK enjoy low risk levels. When your startup deposits cash into a savings account, your funds are held in a secure, low-risk environment – including FSCS insurance for funds up to £85,000.

You won’t get rich from opening a business savings account. However, you’ll generate a steady passive income without taking on any risk.

That makes setting up a business savings account ideal if you’re looking for stable returns and a way to protect your future spending power.

Why have a business savings account?

If you haven’t already set up a business savings account for your small business, now is the perfect time.

Not only do savings accounts enable you to generate income from idle funds, but they also provide your startup with a financial lifeline if business lags or you need to access funding for growth. Read on to discover five key advantages.

1. Earn interest on idle funds

Setting up a business savings account is a simple way to grow idle cash. That’s because your savings balance generates Annual Equivalent Rate (AER) interest.

AER is a form of compound interest deposited regularly into your account as a reward for saving. This often happens monthly, but some banks deposit your interest earnings quarterly or annually.

The advantage of compound interest is that you earn money on the interest you’ve already earned rather than simply earning interest on your initial deposit.

So, the more you deposit into your account, the more interest you’ll earn. Even a modest interest rate will enable you to build a sizable amount of passive income over time using surplus cash.

This extra money can go a long way towards supporting future investments or helping cover unexpected costs.

2. Create a financial safety net

It’s possible to start a business here in the UK with minimal investment. But even as a young company with minimal overheads, you’ve got to maintain a certain amount of cash to ensure you can continue operating.

Quickbooks research suggests that one in seven UK companies struggles with cash flow to the extent that they’re often unable to pay their employees at the end of the month.

Startups are particularly vulnerable to cash flow problems. Late or unpaid invoices, emergency stock, and unexpected surges or dips in demand often wreak havoc on new businesses.

A dedicated business savings account enables you to cover costs as they arise without eradicating your operating cash. That means you can protect your team knowing you’ve always got a way to pay your team.

Meanwhile, a savings account can act as your startup’s rainy-day fund. Backed by that financial safety net, your business can stay afloat during slow periods, economic downturns, or emergencies without scrambling for a business loan or making tough choices about which bills to defer.

3. Develop financial discipline

Separating your business savings from operational funds can go a long way towards helping you achieve financial discipline.

By placing your company’s savings fund in a separate account, you’ll drastically reduce the risk of overspending. That’s because it reinforces budgeting limits and sets financial boundaries. This is especially true if you opt for an advance notice savings account that you can’t access instantly. 

Separating company finances also gives founders a better picture of how much money is available for day-to-day operations rather than long-term planning. This promotes better budgeting and cash flow management, essential skills for any founder.

4. Improve business credit rating

UK Government figures indicate that 46% of businesses relied on external finance to keep operations afloat in 2024. Around one in ten companies required business loans.

If you ever find yourself in that situation and need to apply for a business loan, you’ll thank yourself for building up a business savings account. Here’s why:

When you apply for a loan or attempt to win over potential investors, you’ll find that lenders and funding institutions perform a lot of due diligence. They’ll want to see a snapshot of your company’s finances to assess how your business manages its money.

While business savings accounts don’t directly affect your credit score, they demonstrate financial discipline, which is something lenders consider when making decisions.

5. Build funds in a low-risk way

If you want to generate passive income without assuming risk, a business savings account is your best option.

Some business owners choose to invest idle funds in the stock market. Interest rates on savings accounts won’t match high-return investments, but for many startups, that stability is more valuable.

By contrast, the money you deposit in a business savings account is protected by the Financial Services Compensation Scheme (FSCS). That means if your bank were to go out of business, any deposit you’ve made is insured for up to £85,000.

As a result, depositing into a savings account is about the safest place you can park your cash and still earn interest.

Business savings vs current account

A business current account and a savings account serve different financial needs, and new founders often wonder how they differ.

Here’s how a business savings account differs from a current account:

• Interest: A savings account accrues interest. The money your business deposits into a current account won’t generate interest.
• Access: A current account provides instant access to your business funds. Some business savings accounts have restricted access.
• Transactions: Savings accounts often limit the number of daily transactions you can carry out. Some regular payments like standing orders, Direct Debits, or BACS transfers can’t be completed from a savings account.

Because of these key differences, a business current account is the perfect solution to help your business manage daily cash flow and short-term liquidity. Meanwhile, a business savings account is ideal for longer-term planning, such as setting aside money for tax liabilities, investments, or emergencies.

Ideally, your business should open both a business current account and a business savings account to leverage the best of both worlds.

What’s the best type of business savings account?

Now that we’ve covered what a business savings account is and how it stands apart from current accounts, let’s take a deeper dive into the different kinds of business savings accounts in the UK:

Easy‑access business savings account

An easy-access business savings account is a simple banking product that allows companies to withdraw funds anytime without a notice period or penalties.

• Who it’s for: Startups that require liquidity
• Key benefits: Instant or same-day access to your funds
• Ideal use case: Rainy day fund to manage budget buffers, surprise tax bills, or cash flow dips

Interest rates are typically modest, but you can build liquidity while staying nimble.

Notice accounts

A notice account is a type of UK business savings account that requires advance notice to withdraw funds. Your bank decides the notice period, but most notice periods are either 30, 95, or 180 days.

• Who it’s for: Established companies with idle cash
• Key benefits: Higher interest rates
• Ideal use case: Earn passive income on cash reserves you don’t need access to

According to research commissioned by United Trust Bank, UK businesses could miss out on up to £992 million in annual interest by keeping company money in low-interest business easy-access accounts.

Setting up a notice account is a potential solution to reaping the benefits of those higher interest rates.

Notice accounts typically give you a higher AER in exchange for waiting longer to get your money back. That means you’ll generate higher levels of compound interest on the money you place in a notice account.

Fixed-term accounts

A fixed-term account is a business savings product in which money is locked in for a set term and cannot be accessed. These terms typically vary between six and 24 months.

Locking up your cash can earn you a much higher interest rate. In most cases, a fixed-term account’s interest will outpace a notice account, too.

• Who it’s for: Established companies with large cash reserves
• Key benefits: Highest possible interest rates
• Ideal use case: Building interest on cash reserves you can afford to lock up

Some people also refer to fixed-term accounts as ‘bond accounts’. But both names mean the same thing.

How do you open a business savings account?

Regardless of the type of business savings account you choose to set up, the application process is usually fast and straightforward.

Here’s how it works:

1. Check your eligibility

First, you’ll need to see if you’re eligible to open a business savings account. Most UK lenders require: 

• Your business to be UK-registered
• You to have an existing UK business current account
• You to be a director, owner, or company secretary

These rules may vary slightly by bank, so check with your bank before applying to set up your account.

2. Choose which type of account is right for you

After determining your eligibility, it’s time to decide which account best suits your business needs.

Assess the flexibility you’ll need to access your deposits. Then, compare interest rates, bank fees, withdrawal limits, and other account restrictions.

When in doubt, contact all the banks on your shortlist.

Don’t be afraid to ask these questions and let them know you’re trying to choose between their bank and another institution. They should be able to answer any questions and even give you special introductory offers on benefits.

3. Prepare the required documents

Next, it’s time to gather all the documents you’ll need to complete your account application form.

Most banks will require the following information:

• Business name 
• Business address 
• Company registration number (if applicable) 
• Proof of identity 
• Proof of address 
• Business bank account details 

In some cases, you might also be asked for HMRC documents like VAT registration or your Unique Taxpayer Reference (UTR number), and the expected amount of your initial deposit.

4. Complete the account application form

Today, most challenger and traditional banks offer a convenient and 100% online application process.

If you have all your documentation to hand, the application process may take as little as 10 minutes. Simply work your way through each question and answer accurately and honestly.

After you hit ‘submit’, approval times could take 10 minutes to a couple of working days. It just depends on the provider. Sometimes, you may also be asked for additional information or documentation before a decision is made.

5. Fund your account

Once your account has been approved and opened, you must transfer money into your new savings account, using your business current account.

Some business savings accounts have a minimum opening balance threshold you’ll need to meet. This is often simply £1, but other accounts might require an initial deposit of £1,000 or more.

After this step, rest assured knowing you can leverage all the benefits of a business savings account while focusing on your business’ day-to-day operations.

Pro tips for setting up a business savings account

Setting up a business savings account for the first time? Here are a few pro tips to help you get the right fit for your startup:

1. Choose an account type that matches your cash flow strategy

It’s easy to gravitate towards the highest interest rates. But make sure that the account types you’re looking at align with your cash flow needs.

For example, if you want quick access to your savings for tax payments or emergency costs, it makes more sense to opt for a lower-interest, easy-access savings account.

By contrast, it makes more sense to set up a notice or fixed-rate account if your business has large reserves, and you know you won’t need them for several months.

Want to get the best of both worlds? Split your funds and set up an easy-access savings account for emergencies and a higher-yield notice account for longer-term savings.

2. Track of introductory rates and interest drop-offs

Many business savings accounts offer great introductory interest rates that only last for a set term. That means your attractive 4.6% interest rate could drop to 2.3% after 12 months.

When you sign up for these accounts, record and track offer expiry dates. When a great introductory offer is nearing its end, review your account options and switch to a different provider.

It’s also worth contacting your bank to let them know you’re considering moving your money to a different bank because your rate is expiring. Some banks may respond with loyalty offers, so always ask.

3. Only go for an account with FSCS protection

We’ve already mentioned that most business savings accounts have FSCS protection. That means you’re insured for up to £85,000 if your business account provider goes out of business.

Most account providers in the UK have this protection in place. But double-check before you apply and avoid any financial institution that isn’t insured.

Have more than £85,000 in savings? Split it between multiple FSCS-covered institutions. This will ensure all your funds are protected.
