Accountants in Londonderry
Londonderry has 20 accountancy firms on record, including 9 supervised for anti-money-laundering and 7 with professional-body membership. Because "accountant" is not a protected title in the UK, anyone can use it - so every listing here is cross-checked against Companies House, the HMRC anti-money-laundering register and the professional bodies, with the source and date shown on each claim. When you compare Londonderry firms, look past price to two things on the public record: that the firm is supervised for anti-money-laundering (a legal requirement) and, ideally, that it belongs to a body such as ICAEW, ACCA or AAT. Both are shown on every profile below.

How to choose an accountant in Londonderry
- Confirm AML supervision. Every UK accountant must be supervised for anti-money-laundering, by HMRC or a professional body. It is a legal requirement and the first thing to check.
- Look for a professional body. Membership of ICAEW, ACCA or AAT means real qualifications and a complaints route; the title "accountant" on its own is not protected.
- Compare fixed-fee quotes. Most Londonderry firms quote a fixed fee per service, so get two or three and compare like for like rather than hourly rates.
- Watch the red flags. No AML registration, no engagement letter, vague pricing or any pressure to under-declare are all reasons to walk away.
