How to Check an Accountant Is Qualified, Insured and Trustworthy (UK 2026 Checklist)

Last updated: June 2026 · Reviewed by the AccountingFirms editorial team (UK qualified-accountant network)

Anyone can call themselves an “accountant” in the UK, because the title isn’t legally protected. That makes it essential to verify a few key things before you trust someone with your finances. Use this 2026 checklist to confirm an accountant is qualified, insured and trustworthy before you sign up.

1. Check they are qualified (chartered or certified)

Look for recognised qualifications and membership of a professional body:

• ACA — Chartered Accountant (ICAEW)
• ACCA — Chartered Certified Accountant
• AAT — Association of Accounting Technicians
• CIMA — Chartered Management Accountant

You can verify membership directly on each body’s online register. A qualified accountant is bound by professional standards, ethics rules and ongoing training, which an unregulated bookkeeper may not be.

2. Confirm they hold professional indemnity insurance

Professional indemnity (PII) insurance protects you if the accountant makes a mistake that costs you money. Reputable firms carry it as a condition of their professional body membership. Always ask for confirmation, it’s a clear sign of an accountable, established practice.

3. Make sure they are AML supervised

By law, UK accountants must be supervised for anti-money-laundering (AML) purposes, either by their professional body or by HMRC. A firm that can’t tell you who supervises them is a red flag.

4. Read genuine client reviews and ratings

Independent reviews reveal what it’s really like to work with a firm, responsiveness, reliability and value. Look for:

• Verified reviews on independent platforms rather than only testimonials on their own site.
• A consistent track record over time, not just a handful of recent five-star ratings.
• How the firm responds to any negative feedback.

5. Consider location and office trust signals

Whether you want a local face-to-face accountant or a fully remote one, check the basics:

• A real, verifiable business address (not just a PO box).
• A registered company you can look up at Companies House.
• A professional website, business email and contactable phone number.
• For local support, an office within reasonable reach for meetings.

Many UK accountants now work remotely with cloud software, so you can choose the best fit nationwide, just make sure the trust signals stack up.

6. Check fees are transparent

A trustworthy accountant gives a clear, fixed quote with no hidden extras. Ask exactly what’s included, accounts, tax returns, payroll, VAT, software and support, so you can compare like for like.

7. Ask about software, security and communication

• Software: Do they use Making Tax Digital-compatible cloud tools like Xero, QuickBooks or FreeAgent?
• Data security: Are they GDPR compliant and clear about how your data is stored?
• Communication: Will you have a named contact, and how quickly do they respond?

8. Check experience in your sector

An accountant who regularly works with businesses like yours, contractors, landlords, e-commerce, limited companies, will spot sector-specific reliefs and pitfalls a generalist might miss.
