Switching accountants: how it actually works

Thinking about moving accountants but worried it’ll be a hassle? It’s far simpler than most people expect, and you can do it at any time of year. Here’s exactly how it works.

Why people hesitate (and why they shouldn’t)

Most of the worry comes down to three myths: that you have to wait until your year end, that the handover will be a fight, and that you’ll be left doing all the admin. None of them hold up. The process is well trodden, the professional bodies expect a smooth transfer, and the new firm does the heavy lifting.

You don’t have to wait for year end

There’s no rule that ties you to your accounting date. You can move mid year, mid quarter, whenever suits. In fact, moving sooner often means your new accountant can catch issues, an overpaid tax bill, a missed deadline, a VAT misstep, before they become expensive.

What actually happens, step by step

1. You appoint the new firm

You sign a letter of engagement and a couple of HMRC authorisations so the new accountant can act as your agent. That’s the bulk of your involvement.

2. Professional clearance

The new accountant writes to your current one with a standard “professional clearance” letter. This asks for your records and confirms there’s no professional reason they shouldn’t take you on. It’s a courtesy step that happens between firms, you don’t have to manage it.

3. Handover of records

Your previous accountant passes over the essentials: prior year accounts, tax computations and returns, payroll and VAT data, and the working papers behind your figures. Good firms turn this around quickly.

4. Agent authorisation with HMRC

The new firm registers as your agent for the relevant taxes, Self Assessment, Corporation Tax, VAT, PAYE, so they can deal with HMRC on your behalf. And that’s the move done.

What records are you entitled to?

Your books and the information needed to run your affairs are yours. A previous accountant can hold a lien over certain documents if fees are genuinely outstanding, so settle any final bill, but they shouldn’t obstruct a reasonable handover of your records.

How to choose the right firm

Don’t just move for the sake of it, move to something better. Look for:

• Responsiveness, a named person who actually replies, not a ticket number.
• Fixed, transparent fees so there are no surprise charges for a phone call.
• Proactive advice, a firm that tells you things before you ask, not just files what’s due.
• Relevant experience, someone who understands your sector, your size and your ambitions.

Red flags to watch for

Be wary of vague pricing, slow communication during the sales process (it rarely improves later), and anyone who can’t clearly explain how they’ll add value beyond filing. The relationship should feel like a partnership, not a transaction.

How long it takes

Typically a couple of weeks, most of which is simply waiting on the handover from the outgoing firm. From your side it’s a light touch, a few signatures and a short conversation about your goals.
