If you are searching for “how to switch accountants UK”, chances are the problem is not simply that your accounts need filing. Perhaps replies are slow, fees arrive without warning, or your accountant only gets in touch once a deadline is already close. For a growing business, landlord or independent professional, that is not a minor irritation. It leaves you making commercial decisions without a clear view of tax, cash flow or profit.
Changing accountant is usually far simpler than people expect. A capable new adviser should manage the handover professionally, request the information they need and keep an eye on deadlines. Your job is to choose carefully, give clear authority and avoid leaving the move until the last possible week.
When changing accountants is the right call
A late tax return is an obvious reason to move, but it is not the only one. You may be receiving compliant accounts while getting very little useful advice between year ends. That arrangement can suit a straightforward micro-business. It becomes limiting when you are taking on staff, buying property, drawing dividends, dealing in crypto assets, considering investment sales or trying to understand why turnover is rising while cash is not.
Other warning signs include being passed between junior staff, having to chase basic answers, unclear scope, and invoices that bear little resemblance to the fee you expected. None of these automatically means your current accountant is poor. Sometimes the relationship has simply outgrown the service model.
The better question is not, “Can they submit the forms?” It is, “Do I have access to the financial judgement I need before I make an important decision?”
Before you switch accountants in the UK
Start by checking your engagement letter with the existing firm. It should explain the notice period, what services are included, whether any work is still outstanding and how final fees are calculated. If you are unhappy with a bill, raise it promptly and calmly. A genuine fee dispute need not prevent a move, but it can slow the release of certain records or the final handover.
Next, list every service your accountant currently covers. This may include company accounts, corporation tax, VAT returns, payroll, self-assessment, confirmation statements, bookkeeping, management accounts and landlord tax returns. A switch often goes wrong because one of these responsibilities is assumed rather than agreed.
You should also identify the dates that matter over the next three months. Note your VAT filing and payment dates, payroll runs, Companies House deadlines, corporation tax payment date, year-end and self-assessment deadlines. A new accountant can take control of these areas, but they need an accurate starting point.
The practical process for switching accountants
Choose the new accountant before ending the old arrangement
Do not resign from your current accountant before you know who will take over and what they will do. Ask the prospective firm whether it is accepting new clients, which services it will assume, what information it needs and how it will price the work. Fixed fees are valuable only when the scope is clear, so make sure both sides understand whether bookkeeping clean-up, overdue returns or advisory work are included.
For an owner-managed company, this is also the moment to ask who will actually advise you. Direct access to a senior accountant is different from a relationship managed through a call queue, even if both firms offer the same headline services.
Formally appoint the new adviser
Once you are happy, the new accountant will normally ask you to sign an engagement letter and authority to act. This sets out the services, responsibilities, fees and data protection arrangements. It is not paperwork for paperwork’s sake. It establishes who is responsible for what from the agreed start date.
They may also need to verify your identity and, for a company, the identity of directors and beneficial owners. These checks are a standard part of anti-money laundering obligations.
Give notice and authorise professional clearance
Tell your current accountant in writing that you are ending the engagement. Keep it brief and professional. You do not need to justify a commercial decision or turn it into a difficult conversation.
With your permission, the incoming accountant will send a professional clearance letter to the outgoing firm. This asks whether there are any professional reasons the new firm should know about before accepting the appointment, and requests relevant handover information. It is a normal process, not an accusation.
Most professional firms handle this efficiently. If yours does not, avoid getting drawn into an argument. Your new accountant can explain what is still needed and help you obtain records directly where appropriate.
Transfer records and system access
The handover should cover more than a set of PDF accounts. The incoming accountant may need prior year accounts and tax returns, trial balances, corporation tax computations, VAT records, payroll reports, bookkeeping data, fixed asset schedules, dividend paperwork and details of any open HMRC queries.
Digital access matters too. Check who controls the accounting software subscription, bank feeds, payroll platform, Companies House authentication code and HMRC agent authorisations. Your former accountant should not retain sole control of systems that your business relies on. Equally, do not casually share personal passwords. Use formal user access and authorisation routes wherever possible.
Do not leave the switch too late
You can change accountants at any point in the year, including shortly before a filing deadline. But urgency narrows the choices available. A responsible accountant may decline work if there is not enough time to review the records properly, especially where bookkeeping is incomplete or a tax position is complex.
The best time to move is often shortly after your year end or after a VAT return has been filed. The books are more likely to be up to date and responsibility is easier to define. That said, waiting another six months for a neat handover is rarely sensible if you are receiving poor advice now.
If a deadline is close, be upfront. State exactly what is due, when it is due and what has already been completed. A good adviser will tell you plainly whether the work can be done safely, what information is missing and what the fee reflects.
What a good new accountant should ask you
Be wary of an accountant who promises to take everything on without questions. Senior financial advice starts with understanding the business, not simply collecting a Government Gateway reference.
Expect questions about how you make money, your margins, plans for the next year, borrowing, property income, investments, payroll, VAT position and the quality of your bookkeeping. A director taking dividends needs different support from a landlord with several properties. A consultant paid through a limited company faces different decisions from an online retailer managing stock and thin margins.
You should also be able to ask practical questions in return. Who will be your day-to-day contact? How quickly can you expect a response? Will you receive proactive reminders? Is support included when you are deciding whether to buy equipment, take on a staff member or extract profits? What happens if your records need repairing before the year-end work can begin?
The answers reveal whether you are buying a compliance service or a genuine finance partner. Both have their place. The difference is particularly valuable when you need to act before the numbers become history.
Keep the relationship professional
Changing accountant can feel personal, especially if you have worked with the same person for years. It does not need to be. Thank them for their work, confirm the end date and ask them to co-operate with the professional handover. Save emotional energy for choosing the service your business needs next.
It is also sensible to retain copies of key records yourself. Your accounts, returns, tax computations, property purchase documents and major correspondence are business records, not something you should have to hunt down years later.
A move to a firm such as SolutioRemote Accounting should leave you with more than a new contact name. You should come away with a clearer picture of what is due, what the numbers mean and who will help you think before the next important decision.
