In the UK, the word "accountant" is not a protected title. Anyone can call themselves an accountant, regardless of their training, qualifications, or experience. There is no legal requirement to hold a qualification before offering accounting services to the public. This makes checking qualifications essential before you hand over your financial records. The good news is that verifying someone is genuine takes no more than five minutes using the free online registers maintained by the main professional bodies, and it could save you considerable trouble down the line.

Why checking qualifications matters

Hiring a qualified, regulated accountant gives you important protections that simply do not exist if you engage someone without recognised credentials. Understanding what you lose when you skip this check is the best motivation to do it properly.

No regulatory oversight. Accountants who are members of a recognised body, such as ICAEW, ACCA, CIMA, or AAT, are subject to ongoing regulation. They must keep their technical knowledge current through continuing professional development, comply with an ethical code, and can be investigated and disciplined if they fall short. An unqualified accountant has no such obligations and no one to answer to.

No mandatory professional indemnity insurance. Regulated members are required to hold professional indemnity insurance (PII), which provides a route to compensation if an error or act of negligence causes you financial loss. Without PII, you may have no practical recourse even if you win a legal dispute.

No disciplinary process. If a regulated accountant acts improperly, you can make a formal complaint to their professional body. The body can investigate, impose sanctions, and in serious cases remove the individual's right to practise. With an unqualified person, that route does not exist.

Real risks include errors on your tax returns, missed HMRC deadlines leading to penalties, and advice that is simply wrong. In the worst cases, mistakes by unqualified operators have cost clients tens of thousands of pounds in unpaid tax, penalties, and interest, with little realistic prospect of recovery.

How to check ICAEW membership

The Institute of Chartered Accountants in England and Wales (ICAEW) maintains a free public search tool at icaew.com/find-a-chartered-accountant. You can search by individual name or by firm name.

ICAEW members use one of two designations:

  • ACA (Associate Chartered Accountant) — awarded on completion of the qualification and the required period of practical experience.
  • FCA (Fellow Chartered Accountant) — awarded after at least five years of post-qualification membership and demonstrated contribution to the profession.

When you find a member on the register, check whether any disciplinary notes are recorded against their entry. ICAEW publishes sanctions and findings from its disciplinary process, so you can see whether a member has had any formal action taken against them. An entry that shows a current, active membership with no adverse notes is what you are looking for.

How to check ACCA membership

The Association of Chartered Certified Accountants (ACCA) has a global public register available at accaglobal.com. You can search by the accountant's name to confirm their membership status.

ACCA uses two designations:

  • ACCA (Associate) — the standard membership designation on completion of the qualification.
  • FCCA (Fellow) — awarded to members with at least five years of membership and relevant experience.

If the accountant is running their own practice and providing services directly to the public, they must also hold a current ACCA Practising Certificate. This is a separate requirement from membership. You can check whether their practising certificate is current via the same register. An ACCA member who provides public accounting services without a practising certificate is technically in breach of ACCA's rules, which is itself a warning sign.

How to check CIMA membership

The Chartered Institute of Management Accountants (CIMA) maintains a public member search at cimaglobal.com. CIMA members use the designations ACMA (Associate), FCMA (Fellow), and CGMA (Chartered Global Management Accountant, a joint designation with AICPA).

It is worth understanding what CIMA qualifies members for. CIMA's syllabus focuses on management accounting, business strategy, and internal finance; it is excellent preparation for roles as a finance director, CFO, or in-house financial controller. It is less focused on the compliance and tax work that most small businesses and self-employed people need from a practising accountant.

If a CIMA member is offering public practice services, such as filing your self assessment return or preparing your company accounts, they should ideally also hold a practising certificate from ICAEW or ACCA, as CIMA itself does not have its own practising certificate for public accounting work in the same way.

How to check ICAS membership

The Institute of Chartered Accountants of Scotland (ICAS) is the world's oldest professional accountancy body and grants the CA (Chartered Accountant) designation. ICAS is particularly prominent in Scotland but has members throughout the UK and internationally.

You can search for CA members via the public register at icas.com/find-a-ca. An ICAS CA is equivalent in standing to an ICAEW ACA or FCA, and the qualification is widely respected by HMRC, the courts, and the wider profession.

How to check AAT membership

The Association of Accounting Technicians (AAT) offers a strong practical qualification that is particularly well regarded for bookkeeping and small business accounts work. You can search for AAT members at aat.org.uk.

AAT uses two membership designations:

  • MAAT (Member) — standard membership, awarded on completing the qualification.
  • FMAAT (Fellow) — awarded to experienced senior members.

Crucially, if an AAT member is providing public accounting services, such as preparing accounts or tax returns for clients, they must also hold an AAT Licence to Practise. This licence is separate from general AAT membership and brings additional requirements around PII, CPD, and compliance with AAT's regulations. Confirm that the person holds a current licence if they are operating in practice.

Checking their practising certificate

Any accountant who provides services directly to the public, whether that means preparing your accounts, filing your tax returns, or giving you tax advice, is classed as working "in practice." Most professional bodies require their members to hold a specific practising certificate before they can do this legitimately.

A practising certificate is not just a formality. It confirms that the member has met additional requirements, including holding adequate professional indemnity insurance, completing relevant CPD, and complying with the body's practice regulations. Without it, a member may be technically in breach of their body's rules even if they hold the qualification itself.

When you meet a prospective accountant, ask directly whether they hold a practising certificate and from which body. You can then verify this independently via the relevant body's online register. Any hesitation or vagueness in response to this straightforward question should give you pause.

Checking anti-money laundering registration

Under the Money Laundering Regulations, all UK accountants who provide tax or accounting services to clients must be supervised for anti-money laundering (AML) purposes. This requirement applies to everyone providing these services, not just members of professional bodies.

Supervision can come from two sources:

  • Via their professional body — members of ICAEW, ACCA, CIMA, ICAS, and AAT are automatically supervised for AML purposes by their body, provided they hold the relevant practising certificate or licence. This is the most common route for regulated accountants.
  • Via HMRC directly — accountants who are not members of a recognised professional body, or who provide services that fall outside the scope of their body's supervision, must register for AML supervision directly with HMRC. If an accountant is supervised by HMRC, they should appear on the HMRC AML supervision register, which is publicly accessible at gov.uk.

Ask any prospective accountant directly who their AML supervisor is. A regulated member of ICAEW, ACCA, or another body should be able to answer immediately. If they cannot tell you, or if they claim to be exempt from AML supervision, that is a serious warning sign and you should walk away.

Other checks to make

Beyond the professional body registers, a few additional checks are worth making before you commit to an accountant:

  • Professional indemnity insurance. Ask the accountant to confirm in writing that they hold current PII cover and for what level of indemnity. Regulated members of the main bodies are required to hold this, but it is worth confirming directly.
  • Companies House. If the accountant or firm operates as a limited company, check the company's filing history at Companies House. A company that is overdue on its own accounts or has been subject to a compulsory strike-off notice is not a reassuring sign.
  • Independent reviews. Google Reviews and Trustpilot can give you a genuine sense of how a firm treats its clients. Look for consistent patterns rather than any single review, and pay attention to how the firm responds to negative feedback.

Once you have completed these checks and are confident in the credentials of your preferred candidate, you are in a strong position to proceed. Search for an accountant near you using the AccountingStack directory, where all listed firms are filtered by location and specialism.

Frequently asked questions

Is it illegal to practise as an accountant without a qualification in the UK?

No, it is not illegal. Unlike solicitors, doctors, and some other professionals, the title "accountant" is not legally protected in the UK. This means anyone can describe themselves as an accountant and offer accounting services without holding a qualification or being regulated. However, providing certain services, such as statutory audits, does require specific authorisation. More importantly, anyone providing accounting or tax services must still be registered for anti-money laundering supervision, either via a professional body or directly with HMRC. Providing these services without AML supervision in place is a breach of the Money Laundering Regulations, which does carry criminal penalties.

What happens if I use an unqualified accountant and they make a mistake?

If an unqualified accountant makes an error that costs you money, your options are limited. You may be able to pursue a claim for negligence or breach of contract through the civil courts, but this can be expensive and time-consuming. More importantly, an unqualified accountant is not required to hold professional indemnity insurance, which means even if you win a judgment against them, there may be no money to recover. By contrast, a regulated member of ICAEW, ACCA, or another body must hold PII, giving you a realistic route to compensation through their insurer. You also lose access to the professional body's complaints and disciplinary process, which can be an effective and free way to resolve disputes with regulated members.

How do I find an HMRC-registered tax agent?

An HMRC-authorised tax agent is someone who has registered with HMRC to act on behalf of taxpayers, allowing them to communicate with HMRC directly about your tax affairs. Most qualified accountants who deal with self assessment, PAYE, VAT, or corporation tax will already be registered as HMRC agents. You can ask your accountant to confirm their HMRC agent reference, or ask them to demonstrate that they can log in to HMRC's agent services account on your behalf. This is separate from AML supervision and from professional body membership, but any competent practising accountant should have it in place.
