The Big 4 in Mauritius: What Is Licensed, and What Is Not

The Big 4 in Mauritius are Deloitte, PwC, KPMG and EY, the same four networks that carry the label everywhere else. The label is worth understanding before you use it as a shortlist, because it describes global network membership and not anything a Mauritian regulator recognises. What Mauritian law recognises is narrower and more useful: a licence to audit, issued under the Financial Reporting Act 2004, and three public lists you can check in an afternoon.

Where we sit. B Hub Consulting is a management consultancy founded in 2019, BRN C07000934, registered in the Republic of Mauritius. We are not an audit firm, we hold no audit licence, and we do not file tax returns or administer companies. Half of what a Big 4 firm sells in this market is therefore work we do not do and are not permitted to do, and the article says so wherever that matters.

The Big 4 is a global label, not a Mauritian category

No Mauritian statute, regulator or register uses the phrase. It is a description of four international accounting networks, and each of them reaches Mauritius through a local member firm that is a separate legal entity. That matters commercially in two ways. The brand you are buying is a network standard and a methodology; the people you are buying are a local partnership whose size and composition are a separate question.

It also matters that the four are not the only large accounting and advisory firms on the island. Our own review of the market, in the best consultants in Mauritius compared, sets out the established firms by category with founding years taken from each firm’s own site. A shortlist that begins and ends with four names is a shortlist assembled from a global league table rather than from the Mauritian market.

What each firm publishes about its Mauritius practice

We read the four firms’ own pages on 29 September 2026 and recorded only what they publish there. The gaps are real gaps, not omissions on our part, and they are informative: a buyer who wants to know how many people will actually be available in Port Louis or Ebene has to ask, because three of the four do not say.

One honest conclusion follows from the table. If local bench depth is part of your decision, you cannot get it from the websites, and the four will not all answer the question the same way. Ask for it in writing during selection, in the form that matters: the named individuals who will be on your mandate, their grade, and how much of their time is committed.

Audit is licensed. Consulting is not.

This is the distinction that should shape the shortlist, and it is set out in statute. The Financial Reporting Act 2004 makes auditing a licensed activity and makes the licence personal before it is corporate.

no person shall hold any appointment, or offer any services for remuneration, as an auditor, unless he holds a licence under this Act.

Section 35(1) then attaches the firm to the licence: "No licensed auditor shall, on behalf of a firm, provide audit services, unless that firm is registered as an audit firm by the Council." Section 2 defines a licensed auditor as "a person who has been issued a licence under section 33", and section 52(1) separately prevents a person holding themselves out as a public accountant, or using a description likely to create that impression, without being registered. The full text is published by the Mauritius Institute of Professional Accountants.

Nothing equivalent exists for consulting. There is no consulting licence in Mauritius, no register of consultants, and no statutory description that a firm is prevented from using. We set out what can be checked instead, and how, in how to check a consultancy in Mauritius before you engage it. The practical effect for a board is that the audit half of a Big 4 relationship carries a regulator behind it and the advisory half does not, and the same is true of every other consultancy on the island, ours included.

The three registers you can actually check

The Financial Reporting Council licensing page, read on 29 September 2026, publishes three lists: a List of Audit Firms, a List of Local Licensed Auditors, and a List of Authorised Foreign Auditors. Between them they answer, in public, the only questions in this area that have a documented answer.

• Is the firm registered to provide audit services? The List of Audit Firms answers it. A firm that is not on it cannot sign your accounts, whatever its letterhead says.
• Is the individual partner licensed? The List of Local Licensed Auditors answers it. Section 33 licences a person, so the name on the engagement letter matters as much as the name on the door.
• Is a foreign auditor authorised to act here? The List of Authorised Foreign Auditors answers it, which is the list to check when a group auditor abroad proposes to sign locally.

No list answers the consulting question, because no consulting register exists. That asymmetry is the single most useful thing a buyer can hold in their head when a proposal bundles audit-adjacent assurance work with advisory work in one document.

What a Big 4 firm is usually the right call for

We say this as a competitor, so read it with the interest disclosed. There are mandates where a Big 4 firm is plainly the correct choice, and pretending otherwise would waste your time.

• Statutory audit and anything downstream of it. A licensed activity, and one we do not perform. This is the clearest case of all.
• Tax opinions and filings, and cross-border tax structuring. Deloitte’s Mauritius services list names Tax and Legal; PwC names tax and legal among its lines of service. We do neither.
• A global methodology a foreign board already recognises. When the audience for the work sits in another jurisdiction and needs a name it has seen before, that recognition is part of the deliverable.
• Very large programmes needing many bodies at once. Network scale is real. A firm of principals cannot field forty people next month and should not claim it can.

Where a Big 4 firm is the wrong choice is narrower and more specific than the marketing on either side suggests. It is the cross-disciplinary mandate that does not fit one service line: a national programme that is part policy, part procurement and part engineering; an institutional reform where the behavioural design decides whether the system is used; a structuring question that runs across two financial centres and needs one team holding all of it. Those are the mandates our practice areas are organised around, and the engagements page describes the anonymised versions.

Where B Hub is the wrong choice: statutory audit, tax filing, company administration, and any mandate where the deciding factor is the lowest hourly rate. For the first three you need a licensed audit firm or a licensed management company, and we will say so rather than take the work.

A five-step test before you shortlist

Run this before the request for proposal goes out, not after the presentations. It takes about an hour and it removes most of the ambiguity that otherwise surfaces at contract stage.

1. 01Separate the licensed work from the unlicensed work. Write two lists. Anything that requires a signature under section 33 goes to a licensed audit firm and should probably be procured on its own.
2. 02Check the register for the licensed half. Confirm the firm is on the Financial Reporting Council List of Audit Firms and the signing partner is on the List of Local Licensed Auditors.
3. 03Ask for names and time, in writing, for the unlicensed half. Who is on the mandate, at what grade, for how many days. A brand is not a resourcing plan, and no register will check this for you.
4. 04Ask about independence across the two halves. If the same network audits you, ask what advisory work it is permitted to take and get the answer before the proposal, not during the audit.
5. 05Ask where the firm would decline. Every honest firm has a list. A proposal that claims the whole scope without a single exclusion is telling you something about how it will be staffed.

For the wider market by category, with founding years taken from each firm’s own site, read the best consultants in Mauritius compared. For the distinction that catches most buyers before they get as far as a shortlist, read consulting firms against corporate services in Mauritius, and for the checks that replace a register, how to check a consultancy in Mauritius. Our practice areas set out what we take on and what we do not, and you are welcome to put the question to us even if the answer is that you need an audit firm.
