When should I change my accountant?

Why Clients Change Accountants – And Why It Should Never Be a Light Decision

Changing accountants is more common than many people expect, but it is not a decision that should be taken lightly. A good accountant builds up years of knowledge about a client’s business or personal affairs, often working behind the scenes in ways that are not immediately visible.

While there are valid reasons to move accountants — including retirement and changes in ownership — it is important for clients to understand both the value of staying and the realities of moving, before making a decision.

We get approached by clients all the time when they’re unhappy with their existing accountants. We encourage them to give the current accountant a chance to resolve and if it’s not possible then we are happy to support and talk you through the process of transition.

The value of a long-term relationship with your accountant

A long-standing accountant is often far more than someone who prepares accounts or tax returns. Over time, they will typically have:

• Built a detailed understanding of your business model and history

• Acted as your agent with HMRC, handling correspondence and enquiries

• Helped shape internal processes and deadlines

• Advised through growth, difficult periods, or structural changes

• Supported transitions between accounting software or reporting methods

Much of this value is institutional knowledge — things that are never fully written down but make day-to-day compliance and advice smoother and more efficient.

For this reason alone, changing accountants should never be an impulsive decision.

Accounting software and hidden dependencies

Modern accounting relies heavily on software such as Xero, Clearbooks, QuickBooks, Sage, or bespoke systems. Your accountant may have:

• Designed your chart of accounts

• Created custom reports

• Built workflows for VAT, payroll, or management accounts

• Integrated software with tax and compliance processes

When changing accountants, these systems don’t simply “transfer themselves”. A new adviser must understand how everything has been set up and why — which takes time and careful review.

Common reasons clients do change accountants

Despite the benefits of continuity, there are legitimate reasons clients move, including:

• Business growth requiring more specialist or proactive advice

• A change in service expectations or communication style

• Fee structures that no longer feel appropriate

• Changes in ownership or retirement of an accountant

The last point is particularly common.

When an accountant retires or a firm changes hands

Retiring Accountant’s practice or client portfolio is usually transferred to another firm to ensure continuity. In most cases, this works very well and clients experience little or no disruption.

When the new firm may not be the right fit

Accounting is still a relationship-based service. Occasionally, following a change of ownership, clients may find that:

• Communication feels less personal

• Access to a dedicated adviser has changed

• The firm’s processes or pricing structure differ from what they are used to

• The advisory style is more reactive than proactive

This does not necessarily mean the new firm is poor — simply that it may not be the best fit for that particular client.

The real cost of changing accountants

Clients should also be aware that changing accountants involves real work behind the scenes.

For the new accountant, there is a learning curve:

• Reviewing prior year accounts and tax filings

• Understanding your business, systems, and risks

• Rebuilding internal knowledge from scratch

For the client, this can mean:

• Higher initial fees to reflect onboarding time

• Time spent answering questions and providing documents

• Adjustments while new processes settle

These costs are normal and reflect the effort required to take over responsibility properly.

The importance of professional clearance and data transfer

A well-managed change of accountant relies on professional standards.

This includes:

• Professional clearance between firms

• Confirmation that there are no outstanding issues

• Secure transfer of records, working papers, and software access

• Clear agreement on responsibilities and deadlines

Rushing this process or treating it casually increases the risk of errors, delays, or misunderstandings.

When it does make sense to move

Despite the benefits of continuity, there are times when moving is the right decision — particularly if clients experience:

• Persistent communication problems

• Missed deadlines or compliance concerns

• Lack of proactive advice as circumstances change

• A relationship that no longer feels aligned with their needs

In these cases, a considered and well-managed transition can be a positive step.

Conclusion

Most clients benefit from staying with a good accountant over the long term, and changes should never be made lightly. The value of accumulated knowledge, trusted processes, and established HMRC relationships is significant.

However, circumstances do change — through retirement, firm transitions, or evolving client needs. When that happens, understanding the process, the costs involved, and the importance of professional handover ensures that any move is handled smoothly and responsibly.

At 2e Accountants, we regularly support clients when they move from previous accountants. We have a good track record and clients stay with us for long-term.
