Business cash: is the money in your company account as safe, and as busy, as you think?

There is a risk to your capital and you may not get back the full amount invested. The value of investments, as well as the income from them, can fall as well as rise.
For most business owners, the company account is the one thing you check constantly and think about rarely. You watch the balance rise and fall around payroll and the VAT bill, make sure there is enough for the month ahead, and beyond that the cash simply sits there. It feels safe, because it is with a regulated bank, and sensible, because it is there the moment you need it.
That instinct is fair, but it can hide three questions worth asking about the money in your account: how well it is really protected, whether it is earning a fair return, and how much of your week goes into managing it. A 2026 report from the savings platform Insignis, The Big Cash Blind Spot, surveyed 500 UK finance leaders and pointed to all three. It is a commercial provider's research, so read its conclusions with that in mind, but the underlying issues are real.
How protected is it, really?
Most people assume a bank balance is covered in full. Up to a point it is. The Financial Services Compensation Scheme protects eligible deposits up to £120,000 per authorised firm, a limit that rose from £85,000 on 1 December 2025. That cover generally reaches businesses as well as individuals, including most limited companies whatever their size. The phrase that catches people out is 'per authorised firm'. It applies to a banking group, not to each account, so spreading money across several accounts, or even several brands that share one banking licence, still leaves you with a single £120,000 of protection.
For a business with real reserves, that reframes things. Keep several hundred thousand pounds, or more, with one bank and the protected slice is a small part of the whole. Protection is only half the story, though. Even a business that will never need the compensation scheme carries what is often called concentration risk: if your bank freezes accounts, suffers an outage or restricts access, and payroll, suppliers and daily payments all flow through it, the disruption can be serious however sound the bank is.
Take Priya, a fictional client whose situation will feel familiar. She runs a growing engineering firm that had a strong year, and around £900,000 has built up across a current account and a savings account, both with the same bank. On paper it looks tidy. In practice, most of it sits above the protected limit and all of it leans on one banking relationship. Moving some to banks that do not share a licence would lift the protected amount and ease that dependency. The trade-off is more accounts to open, more logins to track, and keeping enough in the working account to run smoothly.
Is it working, or just sitting?
The second question is what all that cash earns. On a large balance, the gap between an old account paying almost nothing and a competitive business savings rate can add up. The Insignis research suggested many businesses were earning well below the better rates on offer, and that a fair number worried about their cash losing value in low interest accounts.
Chasing the top rate is not the whole answer, though. Operational cash has to stay within reach, and the best rates often carry notice periods or fixed terms that tie your money up for months. Interest a business earns is taxable too, so the after-tax gain is smaller than the headline suggests. And cash held long term can lose ground to inflation, which raises a separate question about whether surplus you will not touch for years belongs in cash at all, or somewhere with more growth potential and the risk of falling in value. There is no single right answer, only the one that fits the business.
The time it takes
The third cost never shows on a statement: the time managing the arrangements swallows. The same research put it at roughly four and a half hours a week for senior finance staff, spent moving money, comparing rates, logging into portals and reconciling the lot. The more you spread cash to improve protection and returns, the more relationships you take on to watch over. Tidier protection and lighter admin can pull against each other.
Where savings platforms fit
This is the gap that cash savings platforms, sometimes called deposit aggregators, are built to close. Through one application you can place money across a range of banks and see it in a single view, which cuts the admin and makes spreading cash more practical. The convenience is real, but it comes with things to understand rather than take on trust.
A platform is not itself a bank. Your money is placed with underlying banks, and it is those banks, not the platform, that carry the FSCS protection. So you need to know which banks hold your cash and watch for overlap, because if you already deal with one of them directly, the balances count together under the same £120,000 limit. Recovering your money through an aggregator can also take longer than the usual seven working days if a bank fails. Fees and how the provider is authorised are worth checking too. A platform can move the work rather than remove it, which can still be a sound trade if you go in clear-eyed.
In summary
Business cash rarely gets a second look, yet for many firms it is less protected and less productive than it first appears, and more time-consuming than it should be. It deserves the same review you would give any other asset. The point is not to chase the highest rate or open an account everywhere, but to hold your reserves on purpose: sensibly protected, earning a fair return on what you can spare, and arranged so they do not eat into your week.
