Why people put off switching

It's rarely one big thing that pushes an owner to change accountants. It's usually a slow build-up of smaller frustrations — slow replies, unclear advice, too much chasing, not enough visibility into what's actually going on with the numbers. Everything feels reactive instead of joined up. None of that is a crisis on its own, but add it up over a couple of years and it's easy to see why so many owners eventually decide enough is enough. The switch itself, though, is more routine than most people expect — it's the anticipation that's usually worse than the process.

What to gather before you switch

You don't need everything perfectly organised before you make the move — that's your new accountant's job to sort out. But having the following to hand speeds things up:

  • Your company registration details (or UTR if you're a sole trader) and VAT number if registered.
  • Your current accountant's name, firm and contact details.
  • Your most recent set of accounts or tax return, if you have a copy.
  • Login details for any accounting software you currently use (FreeAgent, Xero, spreadsheets — whatever it is).
  • A rough sense of upcoming deadlines — VAT quarter ends, your Corporation Tax or Self Assessment due dates, payroll run dates.
  • Any outstanding queries or issues you know your current accountant is halfway through.

What to ask your current accountant for

Once you've decided to move, your new accountant will typically contact your old one directly to request professional clearance and your records — this is standard practice between accountants, not a confrontation, and it doesn't require you to referee it. That said, it helps to know what's being asked for on your behalf:

  • Professional clearance — confirmation there's no professional reason (like unpaid fees or an ongoing dispute) preventing the handover.
  • Copies of recent accounts, tax returns and working papers.
  • Payroll records and pension scheme details, if applicable.
  • VAT records and recent returns, if you're VAT registered.
  • Any correspondence with HMRC that's still open or unresolved.

You'll typically need to sign a letter of authority so HMRC recognises the new firm — that's usually the only thing that requires your signature; the rest happens between the accountants.

Timing considerations

You don't need to time a switch around the tax year unless there's a specific reason to — most handovers can happen at any point. That said, a few things are worth factoring in:

  • Switching mid-way through a VAT quarter is fine, but flag it clearly so nothing gets missed between the two firms.
  • If year-end accounts or a Self Assessment deadline is imminent, it's worth being upfront about the date so your new accountant can prioritise accordingly.
  • If payroll is involved, agree a clean cut-off date for the pay run so there's no confusion over who processes what.
  • Switching well ahead of a deadline, rather than right before it, gives your new accountant time to get properly set up rather than firefighting from day one.

What Buzz handles during the handover

We manage the handover end to end — liaising with your previous accountant, requesting professional clearance and the records needed, and getting everything transferred and set up on the right software without you having to chase anyone. The goal is that the only thing you notice is things starting to work better: faster replies, clearer numbers, and a team who actually tells you what's going on instead of leaving you to ask.

Step-by-step checklist

  1. Decide to switch, and have an initial conversation with your new accountant about your business and current situation.
  2. Sign the letter of authority so HMRC recognises the new firm.
  3. Let your new accountant request professional clearance from your current one.
  4. Pass over any login details, recent accounts or documents you already have to hand.
  5. Agree a cut-off date for payroll, VAT or any in-progress work, if applicable.
  6. Let your new accountant get set up on the right software and gather the historical records.
  7. Confirm upcoming deadlines with your new accountant so nothing slips through the gap.
  8. Notify your bank or any third parties who dealt directly with your old accountant, if relevant.
  9. Settle any final fees with your previous accountant, if outstanding.
  10. Sit back — from here it's your new accountant's job to manage the transition, not yours.

What if you're mid-way through something?

A common worry is switching while something's already in progress — a VAT return half done, an ongoing HMRC query, or accounts partway through preparation. None of these are reasons to delay. Your new accountant simply picks up whatever's outstanding as part of the handover, working with the records and clearance provided by your old firm. It's genuinely more disruptive to sit on a decision you've already made than it is to move mid-task — the sooner the handover starts, the sooner someone's actually on top of it.
