Switching business bank accounts isn’t something most founders do lightly. Unlike a personal current account, your business account is woven into how your company operates: supplier payments, payroll, direct debits, accounting integrations, card transactions. Moving it all takes time and carries real risk if something goes wrong mid-transition.

But staying with the wrong bank carries its own costs. Fees that quietly add up. Payments that get blocked or delayed. No one to call when something urgent comes up. Tools that made sense when you had five employees but don’t work anymore now that you have fifty.

If you’re thinking about switching, this guide covers what to actually look for, and what’s worth prioritising depending on the size and complexity of your business.

Why businesses switch – and why many don’t

The most common triggers for switching are frustration, not ambition. A payment gets blocked without explanation. Fees creep up after an introductory period ends. A relationship manager changes and the new one doesn’t know your business. An account setup that was fine at with a small team starts to feel like a blocker with a bigger one.

The reason most businesses don’t switch, even when they’re unhappy, is friction. The hassle of moving direct debits, updating supplier payment details, and notifying customers is often bigger than the pain of staying put.

In practice, the process can be more manageable than it sounds, especially with the right bank helping you through it. But it does require some planning, which is why it’s worth being clear on what you’re actually switching to before you start.

1. Payments: what it costs and what it can handle

Payment fees are one of the clearest places where banks differ, and one of the easiest to underestimate.

Most traditional banks charge per transaction. CHAPS transfers, typically used for large, same-day payments, can cost anywhere from £15 to £30 per transaction at the major high-street banks. Bacs payments often carry a file fee plus a per-item charge. For a business processing significant volumes, this adds up to thousands of pounds a year.

Beyond cost, think about capacity. Can the account handle the payment sizes you regularly need? Some banks apply holds or manual reviews to larger Faster Payments, which can cause real problems when timing matters. Ask specifically what the outbound limits are, including out-of-hours limits, which are often lower and less prominently advertised.

Questions to ask:

  • What are the fees for Faster Payments, international and card payments, Bacs, and CHAPS, both inbound and outbound?
  • Are there limits on outbound Faster Payments, and do these change outside business hours?
  • How are large or unusual payments handled: is there an automated hold or a manual review process?
  • How quickly can I get in touch with someone in case of an issue with payments?

2. Multi-entity and multi-user support

If you run more than one company, whether that’s subsidiaries, SPVs, or holding structures, check carefully how the bank handles multiple entities.

Many banks require a completely separate application, separate onboarding, and separate login for each entity. That means multiple sets of admin, no consolidated view of where money sits across the group, and a lot of unnecessary friction when you need to move funds between entities.

The same applies to user access. A growing finance team typically needs tiered permissions: different people authorising different payment levels, with proper approval workflows. Not all business accounts support this, and retrofitting it later is painful.

Questions to ask:

  • Can I manage multiple entities under one login, and how quickly can new entities be added?
  • Does the account support multi-user access with role-based permissions?
  • Can I set up payment approval workflows that reflect how our finance team actually operates?
  • Can I have my team using cards without having access to the account?
  • Can I trust that I have control over this account?

3. The relationship: who you’re actually dealing with

This matters more than most banks will admit, and less than some will claim.

A dedicated relationship manager sounds good in theory. In practice, at many traditional banks, your relationship manager is covering several hundred clients, turns over regularly, and isn’t reachable when you actually need them.

What you want is a named contact who knows your business, is actually accessible, and doesn’t need briefing from scratch every time you get in touch. For mid-sized businesses managing real complexity – large payments, multiple entities, non-standard corporate structures – this kind of relationship is genuinely useful, not just a nice-to-have.

Ask specifically: how many clients does a typical relationship manager cover? What’s the average tenure? How do you reach them – phone, email, a shared inbox?

Questions to ask:

  • Will I have a named contact, and how accessible are they day-to-day?
  • What’s the typical caseload for a relationship manager?
  • What happens to my relationship if my contact leaves?

4. Onboarding – especially if your structure is complex

For businesses with straightforward UK-registered structures and UK-resident directors, onboarding at most banks is relatively routine. For everyone else, it can be a significant obstacle.

Businesses with foreign directors, international shareholders, complex holding structures, or non-standard ownership arrangements often find themselves rejected outright or stuck in extended due diligence at banks whose onboarding process wasn’t built to handle them. If this applies to your business, it’s worth being upfront about your structure early – ideally before you’ve invested time in an application – and asking the bank directly whether they’ve successfully onboarded similar businesses.

Also ask about timing. “A few working days” means different things at different banks. Get a realistic timeline based on your specific circumstances, not the marketing-page headline.

Questions to ask:

  • Have you successfully onboarded businesses with [my specific structure]?
  • What’s a realistic onboarding timeline given our corporate structure?
  • What information will you need from us upfront to avoid delays?
  • Does the client onboarding team respond to my emails promptly?

5. Accounting integrations and day-to-day usability

The best business bank account is the one that actually works for your finance team That means checking that it connects cleanly to whatever accounting software you’re running – typically Xero, Sage, or QuickBooks – and that the web and app interfaces are functional enough for daily use.

Also worth checking: bulk payment capability (if you’re paying multiple suppliers or running payroll through the account), card management (issuing cards to team members, setting limits, blocking instantly if needed), standing orders, and what reporting and transaction data looks like when you export it.

Questions to ask:

6. FSCS protection and who you’re actually banking with

FSCS protection covers eligible deposits up to £120,000 per depositor at a UK-authorised bank. It’s worth checking this carefully – some digital banking platforms operate as e-money institutions rather than licensed banks, which means deposits are safeguarded differently and FSCS protection may not apply in the same way. OakNorth is a UK-authorised bank, so eligible deposits are protected up to £120,000 per depositor under the FSCS.

If you’re holding significant cash balances, understanding exactly how that money is protected matters. It’s also worth choosing a bank that offers savings options alongside your current account – such as easy access, notice, and fixed-term accounts – so surplus funds can earn interest rather than sitting idle.

Making the switch – a practical checklist

Once you’ve chosen a new bank and your account is open, the actual switching process is manageable if you approach it systematically.

  • List all direct debits and standing orders – contact each provider with your new account details
  • Notify regular payment senders – customers, clients, anyone who pays you regularly
  • Update your accounting software – reconnect bank feeds to the new account
  • Inform HMRC – update your bank details for any tax repayments or payments
  • Run both accounts in parallel briefly – keep the old account open for four to six weeks to catch anything you’ve missed
  • Update your details with Companies House if required for your structure

Most banks will assign someone to help you through the transition. If they don’t offer this proactively, ask.

The bottom line

Switching business bank accounts is a commitment, and it’s worth taking the time to get it right. The banks that look similar on paper often differ significantly in what they can actually handle – particularly for businesses with more complex needs.

The right account isn’t necessarily the one with the highest-profile brand or the lowest headline fee. It’s the one built for the size and complexity of the business you’re running now – and the one you’re building toward.

At OakNorth, we built our Business Banking specifically for mid-market businesses that have outgrown one type of bank and don’t quite fit the other. If you’re at that point, we’re happy to talk through whether we’re the right fit – no obligation.

Your eligible deposits with OakNorth are protected up to £120,000 by the Financial Services Compensation Scheme (FSCS). Subject to eligibility. Terms and conditions apply.
