Business cash beyond the FSCS limit: at a glance
What do I need to know? The Financial Services Compensation Scheme (FSCS) protects eligible deposits up to £120,000 per client, per banking group for your business’s cash reserves.
What does it mean for me? Rising costs, unpredictable interest rates, and inflation mean modern UK small and medium-sized enterprises (SMEs) cannot afford to leave their cash reserves unprotected or underperforming.
Why does it matter? Cash management platforms can help CFOs track and manage FSCS protection and reduce risk.
Research commissioned by Flagstone found that 85% of mid-sized businesses keep their cash with three banks or fewer. With £621,000 in cash on average, that means funds are not fully protected by the FSCS. But amid economic uncertainty, rising costs, and global political instability, CFOs may need to place a greater focus on their cash reserves than ever.
And as a greater number of banks merge, even the most prepared finance teams could find their cash is not as well protected as they thought.
In this guide, you’ll learn about your options for your cash reserves beyond the FSCS limit, including diversifying savings and low-risk alternative investments. You’ll also discover how cash management platforms can make it easier to track your protection as you spread risk across banking licenses.
Why business cash protection matters in an uncertain economy
Business cash reserves are the first line of defence when times get tough, especially for small and medium businesses.
By ensuring operational finances are accessible and earning interest, CFOs can grow contingency and reserve funds with relatively low risk. This is especially important amid an increasingly uncertain economic and political backdrop.
Building a cash buffer for the unexpected
The Bank of England has held the base rate at 3.75% since December 2025. Combined with global political instability, the cost of borrowing is increasingly difficult to predict. And if customers cannot afford to meet their obligations, SMEs may have to write off the income they need to grow their businesses.
The lack of confidence in the long-term economic outlook makes liquid cash reserves an even more powerful tool for building resilience.
Flagstone’s Business Barometer report found that, under current pressures, 43% of UK SMEs doubt they can continue as planned beyond the next two years. A strong buffer can provide important reassurances for businesses considering whether to invest or expand.
Bank consolidation and shrinking FSCS cover
FSCS rules apply per client, per banking group. This makes it possible to protect a much greater share of your business’s cash by spreading funds across accounts with different banking partners.
But this can quickly change when financial institutions merge. For example, Santander completed its acquisition of TSB in 2026, with plans to merge the two banks in 2027. If the merger goes ahead and the banks are brought under a single banking licence, a £240,000 deposit split between the two would only provide £120,000 of protection.
Maintaining full FSCS protection in this environment means reviewing banking licences regularly, or checking your coverage with a business savings platform featuring live tracking. Rebalancing your cash portfolio when banks announce mergers can also help you manage your level of protection, minimising risk.
The SME protection gap
According to research commissioned by Flagstone, 60% of SMEs know they could use a number of different banks to spread risk and maximise returns. But these same businesses believe they haven’t the time, or find it too complicated, to manage large cash reserves for increased FSCS protection.
Additionally, 75% prefer to save their companies’ cash with the same bank. This demonstrates that convenience is often key for small business owners and CFOs. So, a lack of protection may feel like an acceptable risk if it simplifies cash management for time-poor finance leaders.
But inaction can be costly. Balances above £120,000 held in a single bank account remain exposed if your bank goes out of business. And the artificial intelligence (AI) boom has led to record debt issuance, with the Financial Times reporting that companies raised an estimated $466bn by 20 October 2026 since the start of the year to fund their investments. This could lead to a sharp market correction, with uncertain consequences for the financial system at large.
Who is eligible for FSCS protection?
Businesses of all sizes can receive FSCS protection on eligible deposits, provided the accounts are opened with financial institutions regulated by the Prudential Regulation Authority (PRA). On 03 July 2015, cash deposits for large companies became eligible for the scheme, which was previously reserved for smaller businesses.
No matter the size of your business, savings platforms allow you to expand your protection in a manageable way.
How do you protect business cash above FSCS limits?
Protecting business cash beyond the FSCS limit involves considering how you structure and track your deposits.
Splitting deposits across separately licensed banks
Allocating business cash between different financial institutions can help you protect a greater proportion of your reserves. As long as each bank in your portfolio holds its own banking license, you can add £120,000 of coverage each time you open an account with a new financial institution.
Managing accounts with multiple banks yourself could create additional admin. But a savings platform lets you open and manage multiple accounts across different banks in one place. Cash management platforms, like Flagstone, with tools like the Portfolio Optimiser, can help CFOs with large cash reserves track their FSCS protection in moments.
Balancing access, protection, and diversification
Spreading cash deposits between accounts can help you maximise FSCS protection. But how do you keep cash available when you need it, while still earning a competitive return?
Some businesses segment their reserves by how soon they may need their cash. This might include using Instant Access business accounts for day-to-day operating cash, Notice business accounts for anticipated costs, and Fixed Rate business accounts for surplus reserves that can be set aside for longer.
But locking cash away in a fixed rate account can make protection more difficult to manage, depending on the length of the term you choose. Banks usually announce mergers well in advance, and some offer a limited window to withdraw fixed-term deposits without penalty.
Depending on your interest rate, the amount you earn on large fixed-rate deposits can also push a balance over the £120,000 limit by the end of the term. That’s why some businesses factor expected interest into how much they deposit with each bank, as well as laddering maturity dates so that cash becomes available at regular intervals.
What about money market funds, treasury bills, and short-term gilts?
Savings platforms are not the only low-risk option for growing larger cash sums.
For example, money market funds (MMFs) allow businesses and individuals to pool money. Fund managers invest your cash into short-term debt from borrowers like governments, big banks, and large companies.
Alternatively, treasury bills and short-term gilts are both government-backed lending options, making them relatively low-risk options for growing cash reserves outside of savings accounts.
But unlike savings accounts, these alternatives are not covered by the FSCS. So, the security of your money relies on the borrower, not the scheme. The value of MMFs can also fall, and treasury bills and gilts sold before maturity are subject to market prices at the time of sale.
What are the safest structures for business cash?
While no savings or investment option is completely without risk, you can compare the benefits of some of the options to grow business cash below.
Options | Protection | Access | Use cases |
|---|---|---|---|
Instant Access accounts | FSCS | Immediate | Operating cash |
Fixed Rate accounts | FSCS | At maturity | Buffer cash |
Notice accounts | FSCS | After notice period | Strategic cash |
MMFs | Spread across the fund’s borrowers | Same or next day | Buffer cash |
Treasury bills and short-term gilts | UK government-backed | At maturity or sale | Strategic cash |
Proactive business cash management can increase protection
CFOs can make proactive decisions about how they structure business cash to protect reserves, despite ongoing volatility.
Low-risk investments, like MMFs, treasury bills, and short-term gilts, can help you earn low-risk returns on your business’s cash. But savings accounts offer a similarly low-risk way to grow deposits, especially when combined with multiple account types for greater coverage.
And with savings platforms like Flagstone, you can grow your cash reserves and expand FSCS protection without adding complexity.
