This page covers ACCA only. The requirements that apply to every UK practice website are on what UK rules require of a practice website.
ACCA regulates two things that show up directly on a website: the certificate that lets you actually offer accountancy services, and the name and advertising you use to attract the clients who read it.
The practising certificate behind the services you list
Listing services such as accounts preparation, tax returns or business advice on your site puts you squarely inside what ACCA defines as public practice, and the certificate requirement follows from that definition rather than from anything the website itself says. ACCA's own guidance sets the rule out, and it catches almost everyone running client work themselves. Basic book-keeping, restricted to recording data up to trial balance, is the one carve-out that does not need a certificate.
Where the line gets blurry is management-style work: preparing a report a lender will rely on, or giving advice rather than just recording numbers, tips into public practice even if it looks like an extension of book-keeping. If your site lists anything beyond basic book-keeping, the practising certificate is what makes the listing accurate.
Choosing a name that will not be called misleading
ACCA members are free to trade under whatever name they like, subject to rules aimed squarely at stopping a name overstating what the firm actually is. Its own guidance on control and description requirements gives concrete examples: a firm with a handful of offices should not call itself "international" just because one sits overseas, a sole practitioner should not add "and partners", and nobody should add "and Associates" unless two or more genuine associations actually exist. A name must also not risk being confused with another firm's, even one the member could otherwise lay a fair claim to.
None of this stops a name indicating what the firm does. Describing a range or type of service in the name is explicitly fine. What is not fine is a name that reads as bigger, older or more connected than the firm actually is.
Why "Chartered Certified Accountants" cannot sit in your registered name
The description "Chartered Certified Accountant(s)", "Certified Accountant(s)" and the letters ACCA or FCCA are not allowed to form part of a practice's registered name, whether that is a company name filed at Companies House or its equivalent. The reasoning in ACCA's own guidance is straightforward: strict rules govern whether those descriptions may be used at all, and a firm's eligibility can change, so baking the description into the legal name would leave that name misleading the moment the position shifts. Using the description elsewhere on the site, where it can be corrected if things change, is a different matter.
What your advertising can and cannot say
ACCA lets members advertise however they see fit, subject to a short list of rules that all come back to honesty. Content and presentation must not discredit ACCA, the member, the firm or the profession; must not claim superiority over another firm's services by discrediting them; must not mislead, directly or by implication; and must meet ordinary advertising standards on legality, decency, clarity and truthfulness. An advertisement has to read as one. Factual claims are fine provided the member can actually justify them, and any comparison with another firm's fees must not create a misleading impression.
What this page does not repeat
Money laundering supervision, the company details a limited company site has to show, and the privacy and cookie rules around a contact form apply to an ACCA practice the same as any other. They are set out once, in full, on the hub page.
