ACCA vs ICAEW vs AAT: Which Practice Licence Is Right for You?
Last updated:
Quick answer
ACCA and ICAEW practising certificates suit qualified chartered accountants offering full accountancy and tax services, with ICAEW traditionally stronger for audit routes; AAT licensed membership suits technician-level practices focused on bookkeeping, VAT and smaller compliance work, at a lower entry bar and cost.
Key takeaways
- ICAEW is often seen as the strongest route into audit and larger corporate clients.
- ACCA offers a globally recognised, flexible qualification well suited to SME-focused practices.
- AAT is quicker and cheaper to reach practising status, suited to bookkeeping and smaller compliance work.
- All three still require AML supervision and PI insurance regardless of which body you choose.
- Switching bodies later is possible but means re-meeting the new body's eligibility criteria from scratch.
How do ACCA, ICAEW and AAT compare for practice?
ICAEW and ACCA are both chartered-level qualifications supporting a full range of accountancy, tax and audit-adjacent services, while AAT is a technician-level qualification best suited to bookkeeping, VAT and straightforward compliance work.
| Factor | ACCA | ICAEW | AAT |
|---|---|---|---|
| Level | Chartered (Certified) | Chartered | Technician |
| Typical training time | 3–4 years | 3+ years (training contract) | 1–2 years |
| Audit route | Available with extra qualification | Traditionally strong route | Not applicable |
| Practising route | ACCA practising certificate | ICAEW practising certificate | AAT licensed member scheme |
| Best suited to | SME accountancy and tax practices | Audit, larger corporates, broad advisory | Bookkeeping, VAT, smaller compliance |
Which body is best for an SME-focused practice?
ACCA is widely used by practitioners focused on SME accounts, tax and advisory work because it does not require the same structured training contract route as ICAEW and offers flexible practising certificate rules, including a bookkeeping-only exemption.
ICAEW remains a strong and well-recognised choice for SME work too — the choice is often more about where you trained and which designation feels right for your target market than any hard rule about suitability.
Which body is best if I want to do audit work eventually?
ICAEW has traditionally been the most common route into UK audit, given its historic association with the Registered Auditor framework, though ACCA members can also become Registered Auditors with the additional qualification.
If audit is a long-term goal, check the current audit qualification routes for both bodies directly, since requirements and recognised routes can change and neither body publishes a single simplified path.
Is AAT enough to run a bookkeeping and small compliance practice?
Yes, for bookkeeping, VAT, payroll and straightforward personal tax and small company compliance work, AAT licensed membership is a well-established, cost-effective route to practising legitimately with AML supervision included.
AAT is not typically the route for audit or highly complex tax advisory work, but for the bulk of small business compliance needs it is a proportionate and widely respected qualification.
How do costs compare across the three bodies?
AAT is generally the lowest-cost route to qualification and practising status, with ACCA and ICAEW involving longer training periods and higher overall qualification and membership costs.
Exact membership and practising certificate fees change periodically, so always check each body's current fee schedule rather than budgeting from a remembered figure [VERIFY].
Can I switch from one body to another later?
Yes, but you need to meet the new body's own membership and practising certificate eligibility criteria, which may mean additional exams, experience evidence or a transitional membership category.
Practitioners sometimes start with AAT, build a bookkeeping and small compliance client base, then progress to ACCA or ICAEW as their client complexity grows. This is a well-trodden path, but it takes real time and planning rather than a simple form transfer.
How Remindoo helps
Whichever body issues your practising certificate, the day-to-day running of client relationships looks remarkably similar: you need one place to see every client, their status and their history. Remindoo's client management gives every practice, whether ACCA, ICAEW or AAT-licensed, a Companies House sync, a client timeline and notes, so your team has one searchable record instead of relying on individual staff members' inboxes. As your client base grows in complexity — perhaps moving from AAT-level bookkeeping clients toward ACCA or ICAEW-level advisory work — having that single client record in place from day one avoids a painful data migration exercise later.
Frequently asked questions
Is ACCA or ICAEW harder to qualify for?
Both require significant study and supervised experience; ICAEW's training contract route is more structured, while ACCA offers more flexibility in how and where you gain experience.
Can AAT members do tax advisory work?
AAT members can undertake compliance-focused tax work such as personal and small company returns; more complex tax advisory typically sits better with ATT or CTA qualification.
Do ACCA and ICAEW both require a practising certificate for self-employment?
Yes, both require members offering public practice services to hold a practising certificate, with limited exceptions such as ACCA's bookkeeping-only exemption.
Which body is cheapest to maintain each year?
AAT membership and licensing fees are generally lower than ACCA or ICAEW, reflecting its technician-level scope, though all three should be checked against current published fees.
Do clients notice the difference between ACCA and ICAEW?
Most small business clients do not distinguish strongly between the two; larger or audit-requiring clients are more likely to ask about your specific qualification and licence.
Is it worth starting with AAT and upgrading later?
For many bookkeeping and small compliance practices, yes — it gets you trading and earning sooner, with the option to pursue ACCA or ICAEW once you have a client base and capital to invest in further study.
