Cynergy Bank Business Savings

Cynergy Bank is a fully licensed UK bank (formerly Bank of Cyprus UK) offering a genuinely competitive range across one licence: 3.
Best for: Established companies, LLPs and partnerships wanting a full savings range — easy access, notice and fixed — on one bank’s own licence
Watch out: Minimum deposit is £10,000 per account, not £1,000. It’s online-only with no branch access, and you must open it from a nominated business current account in the same name. Easy-access and notice rates are variable; only the fixed bond locks the rate. Sole traders, charities, clubs and trusts can’t open it.
Not ideal if: Not ideal if: you’re a sole trader (not eligible), you have less than £10,000 to deposit, you want branch access, or you need a rate that tracks the base rate in real time.

Our Verdict on the Cynergy Bank Savings Business Bank Account

You’re looking at a fully licensed UK bank with a genuinely complete savings range, not a single headline rate. Cynergy gives you easy access at 3.90% AER, notice accounts up to 4.00%, and fixed bonds up to 4.15% — all on one banking licence.

You’ll want Cynergy on your shortlist if you’re an established business with a real cash reserve. The standout isn’t the rate alone — we rate it for the licence: your deposit sits on Cynergy’s own, independent of the ClearBank pool the big fintech savers share.

Key Pros and Cons

You get breadth and a bank-grade licence here, and we weigh that against a high bar to entry. The catch is the £10,000 minimum.

Your one real hurdle is the entry bar. The £10,000 minimum per account and online-only access make this a bank for firms with cash to deploy, not a startup parking a few thousand pounds.

That’s the catch worth naming up front: if your reserve is smaller, or you bank in a branch, this isn’t built for you. We’d send you to a lower-minimum instant-access account instead.

  • Full range on one licence: easy access 3.90% AER, notice up to 4.00%, fixed bonds up to 4.15% AER.
  • Fully licensed UK bank — FSCS to £120,000 on Cynergy’s own licence, independent of ClearBank.
  • Strong easy-access rate with unlimited withdrawals and no fees.
  • Notice and fixed options for cash you can plan around, up to £10,000,000 per account.
  • £10,000 minimum per account — not for small balances.
  • Online-only, with no branch access.
  • Variable rates on easy access and notice; only the fixed bond locks in.
  • Limited eligibility — sole traders, charities, clubs and trusts can’t open it.

Who Cynergy Bank Savings Is Best For

You’ll get the most from Cynergy if you’re an established company or partnership with £10,000 or more to put to work and you want it on a bank’s own licence. The full range lets you split a reserve into instant, notice and fixed pots from one provider.

Say you run a profitable consultancy holding £150,000 in retained earnings. You leave £50,000 in easy access so your payroll and VAT never stall, give 120 days’ notice on another £50,000 at 3.95% AER, and lock the rest in a one-year bond at 4.15%.

You should look elsewhere if you’re a sole trader, you have under £10,000 to deposit, or you need branch access. The minimum and the eligibility rules shut those readers out — that’s the trade-off with a specialist bank.

Cynergy Bank Savings Account Eligibility and Application

Who Can Open a Cynergy Bank Savings Account

You can open an account if your business is a UK limited company, an LLP or a partnership, and the signatory is 18 or over. Sole traders aren’t eligible, and nor are charities, clubs or trusts — check your structure before you start.

You also need a nominated business current account in the same business name, set up first — so your payroll and supplier runs aren’t held up when you move money. That account is where your funds come from and return to. It’s a deliberate control, not red tape.

What You Need to Apply

Application is online, and you’ll need your company or partnership details plus identity and address verification for the directors, partners and significant shareholders. Cynergy runs the standard checks any deposit-taking bank has to.

You’ll fund the account from your nominated current account, and the minimum opening deposit is £10,000. For a fixed bond, you get a 14-day funding window to transfer the money in before the term locks.

Have your latest figures to hand if you’re asked, and decide your product split before you apply — easy access, notice or fixed. There’s no branch to visit and no relationship manager to wait on.

Cynergy Bank Savings Account Fees and Pricing

Monthly Fees and Plan Options

You pay no monthly fee on any Cynergy savings account — the “pricing” of this product is really its rate ladder. Your choice of product, not a plan tier, sets what you earn.

Easy access pays 3.90% AER (variable). Notice accounts pay more for less liquidity: 3.90% at 95 days, 3.95% at 120 days, and 4.00% AER at 180 days. Fixed bonds run from 4.15% AER for one year to 4.10% over two, three and five years.

We’d pick the product by how soon you’ll need the cash, not by the headline number alone. The highest rate locks your money away the longest. That’s the real cost of the top tier.

Transaction Fees and Charges

You won’t pay transaction fees or withdrawal charges on the easy-access account, and there are no account fees on any product. Moving money in and out of easy access costs nothing, however often you do it.

The only real “charge” is on access, not money: on a notice account you wait out the notice period, and on a fixed bond you can’t withdraw before maturity at all. Plan your VAT and payroll buffers around that before you lock funds away.

Cynergy Bank Savings Features and Business Banking Tools

Invoicing and Expense Management

You won’t find invoicing or expense management here, because these are savings accounts, not a current account. We flag that plainly: raising invoices and tracking spend stays with your main bank or your accounting software.

What you do get is a clean place to hold cash and earn on it. You manage everything through online banking and the mobile app, moving money between products and your nominated account without paperwork.

If you need spend controls or card payments, pair Cynergy savings with your operating account rather than expecting them here. We’d keep the jobs separate — one account runs the business, these earn on the reserve.

Integrations and Accounting Software

You should treat Cynergy savings as standalone deposit accounts rather than a hub that plugs into Xero or QuickBooks — there are no accounting integrations. The money sits with Cynergy and links only to your nominated current account.

You don’t need a software ecosystem for a reserve — you need a strong rate and solid protection. Your bookkeeping feed stays wherever your operating account already lives, so nothing about your month-end changes.

When your accountant pulls the quarter-end figures, the interest shows on your nominated account statement as a clean monthly credit. That’s integration enough for a deposit product.

Cynergy Bank Savings Card Usage and Payments

Spending, Transfers and Limits

You don’t get a spending card with these accounts, and you shouldn’t expect one — they’re savings products, so money moves by transfer. Everything routes through your nominated business current account in both directions.

On easy access you can make unlimited withdrawals at any time through online banking, with no fee. On a notice account you submit a withdrawal request and the funds release after 95, 120 or 180 days. On a fixed bond, there’s no access until the term ends.

When a supplier invoice lands and you need the cash, the easy-access pot is there the moment you transfer it back. Deposits run from £10,000 up to £10,000,000 per account, so there’s ample headroom for a sizeable reserve.

Overseas Payments and FX Fees

You can’t make overseas payments from these savings accounts, and there are no FX fees to weigh because they don’t handle foreign currency. They’re sterling-only deposit accounts, full stop.

If you settle foreign-currency invoices, keep a dedicated multi-currency account such as Wise or Revolut for that and use Cynergy purely to earn on spare sterling. Right tool for one job. Not the same as a currency account.

Cynergy Bank Savings Customer Reviews and Ratings

You can weigh Cynergy’s reputation with reasonable confidence, because the sample is large. When we checked in June 2026, Cynergy held around 4.5 out of 5 on Trustpilot from more than 5,600 reviews — a solid score for a specialist bank, well clear of the high-street incumbents.

One caveat should temper your read: the mobile app scores far lower in the app stores than that headline, largely down to the friction of setting up the Digipass and biometric login. The savings accounts themselves draw few complaints.

You should read that as a bank that does the core job well. When your VAT and payroll buffers have to sit somewhere safe and earn for months on end, a steady record and a real banking licence matter more than app polish.
