Best business savings platforms 2026

Signing up to a business savings platform can give your company access to a much wider range of savings rates with zero faff while maximising FSCS protection. Here are our picks of the UK's top platforms.

Leaving your company’s cash reserve in a standard, zero-interest business current account means you’re not allowing this money to contribute to all the effort you make running a business day-to-day.

If your business is holding onto tax money, emergency reserves, or capital for a future expansion, a business savings platform allows you to spread your funds across multiple banks to max out interest rates and ensure complete FSCS protection, all through a single dashboard.

Why we like it

With over 250 accounts from more than 50 partner banks or building societies to choose from, Flagstone has the best panel we've seen. Fixed-term accounts? Notice accounts? Instant access accounts? Check, check and check. Flagstone uses a share-of-interest model, which means that it makes money by shaving off a little of the interest paid out on client funds. But the rates you see in the platform take this into account, so what you see is what you get. Platforms like Flagstone are sometimes able to use the clout of their large user-base to negotiate better rates with banks, so you can still expect to find market-leading rates. Many businesses prefer this approach to a percentage-of-deposit model. Flagstone is working hard to convince businesses that they don't have to settle for their regular high-street bank – most recently pushing into multi-currency savings where it'll be head-to-head with the likes of Airwallex.

Pros

  • Market-leading panel of accounts
  • Multi-currency accounts
  • All withdrawals are to your single, verified business current account

Cons

  • Min. initial deposit of £100,000

Best for smaller deposits

Why we like it

With Akoni there's no minimum initial deposit to get started, though account-specific minimums set by partner banks will still apply. Akoni also stands out for its liquidity analysis tools – i.e. it's good at keeping you across how much cash you have access to today and how accessible the rest is (e.g. available within x days or locked away until a set date). Akoni is designed to help you maximise your interest earnings while keeping a liquidity strategy that's sensible for your specific company and its cashflow and outlook.

Pros

  • No minimum investment to get started
  • All withdrawals are to your single, verified business current account
  • Advanced liquidity analysis

Cons

  • Percentage-based fee per deposit
  • Fewer accounts to choose from than some competitor platforms
  • No multi-currency accounts
  • No app

Best for security features

Why we like it

With Insignis all transactions require two approvals from different authorised users – one user initiates the transaction, and another user has to green-light it. Funds can only leave the Insignis platform by going back to your company's pre-verified designated current account – so it's not possible for the funds to go to a third party, at least initially. Like all the platforms we've compared here, Insignis operates under the ISO 27001 data security frameworks, which is a pretty dry way of saying unmodifiable audit trails, strict employee access controls, and annual third-party risk assessments to ensure all transaction data stays encrypted and protected against cyber threats.

Pros

  • Dual authorisation workflows
  • All withdrawals are to your single, verified business current account
  • Multi-currency accounts

Cons

  • Annual platform fee of 0.25% of funds held on the platform (or 0.2% if over £.5m, 0.15% if over £2m and 0.1% if over £10m)
  • No app

Why we like it

Like Flagstone, Bondsmith uses a share-of-interest model, so it takes a little of your interest to be profitable, but the rates you see in the platform have taken this into account. What you see is what you get. It's a simple, clean platform for businesses to spread their cash deposits across banking institutions (leveraging separate FSCS limits), though its panel could be larger.

Pros

  • All withdrawals are to your single, verified business current account

Cons

  • Fewer accounts to choose from than some competitor platforms
  • Min. initial deposit of £100,000
  • No multi-currency accounts
  • No app

How to choose the best business savings platform

Here are the four main factors to consider when choosing one:

  1. Supported accounts.A lot of business savings platforms only partner with a select group of challenger banks or building societies. Check exactly how many partner banks a platform connects to so you can maximize your interest
  2. FSCS protection.To protect your balance under the full FSCS limit per banking license, you’ll want to split cash across multiple providers. Look for a platform with built-in allocation tools or balance alerts.
  3. Minimum deposit requirements. Some business savings platforms cater to large corporates and ask for an eye-watering starting. If you run a smaller SME or startup, make sure the platform allows lower minimum deposits.
  4. Platform fees. Most platforms don’t charge an upfront fee to businesses because they take a tiny cut directly from the bank’s wholesale interest rate. However, others charge an annual account management fee or transfer fee.

What is a business savings platform?

A business savings platform (or cash deposit marketplace) is a digital portal that connects your business with dozens of partner banks offering various savings accounts.

Instead of going through the soul-destroying process of filling out Know Your Customer (KYC) forms and anti-money laundering paperwork for 5 different banks, you fill out one application with the platform. Once approved, you can move your company’s funds between competing banks and rates with a few clicks.

What are the pros and cons of using a business savings platform?

Pros

  • Maximise interest with minimal effort by easily moving cash across banks.
  • Simplified FSCS protection by spreading cash reserves across multiple banking licenses.
  • Single point of admin making everything easier to manage.
  • Reduce counterparty risk by not storing all your corporate eggs in one basket.

Cons

  • Many dedicated business platforms require a high minimum initial deposit.
  • Not all platforms cover every bank.
  • Slightly lower net yields than direct applications because platforms take a small cut.

Bottom line

Holding too much cash in a zero-interest current account hurts your bottom line. Business savings platforms give you the flexibility, security, and yield of a multi-bank strategy without the operational nightmare of managing multiple logins and paper trails.

If your business holds over £50,000 in cash, using the best business savings platform possible is one of the easiest financial wins available.
