CIA Contractor Registration in Mauritius: What It Means When Hiring (formerly CIDB)
The statutory register every Mauritian client should check before signing — what changed when the CIDB became the Construction Industry Authority, how to read the number, and the five checks that take five minutes.
The Construction Industry Authority (CIA) is the statutory regulator of the Mauritian construction industry, having replaced the Construction Industry Development Board (CIDB) in June 2024 under the CIA Act 2023. Before hiring any contractor for construction, MEP or building works, ask for their registration number and verify it with the CIA — it remains the single fastest legitimacy check available to a Mauritian client.
From CIDB to CIA: what changed
The CIA Act 2023, voted in Parliament in November 2023, merged the former CIDB with the Building Control Advisory Council into one apex regulator, operational since June 2024 under the aegis of the Ministry of National Infrastructure. The mandate widened — building control, standards and industry development now sit under one roof — but the core function clients care about is unchanged: the CIA maintains the official register of contractors and consultants, graded by category of works and by the size of contract a firm may undertake. Registrations issued under the former CIDB regime carry the old numbering; verification is now through the CIA.
How to read a registration number
A contractor registration encodes the category of works. Using BFC Ltd's own registrations, issued under the previous CIDB numbering and verifiable with the CIA, as a live example:
| Registration | Category | Covers |
|---|---|---|
| CT/CE/L/M/04338 | Civil Engineering Construction Works | Groundworks, structures, drainage, external works |
| CT/MEP/L/M/04339 | Mechanical, Electrical & Plumbing Works | Electrical installation, plumbing, HVAC and mechanical services |
| CT/BW/L/M/04340 | Building Construction Works | Building works, renovation, fit-out and refurbishment |
The category letters tell you what the firm is registered for. A contractor registered only for building works is not registered for your electrical installation; a firm with no registration at all should not be pricing works that legally require one.
Why it matters to you as a client
- Legality. Registration is a statutory requirement for undertaking works in the registered categories — engaging an unregistered contractor exposes the project, not just the contractor.
- Traceability. A registered firm is an identifiable legal entity with a BRN, an address and something to lose. The cheapest quote from an untraceable operator is not cheap when the defects appear and the phone goes silent.
- Insurance & recourse. Claims, guarantees and formal dispute routes assume a registered counterparty. Verbal arrangements with unregistered operators leave you nothing to enforce.
- Scope match. The category check catches a common Mauritian failure mode: a general builder "also doing" the electrics. MEP is its own registration category for a reason.
The five-minute due-diligence check
- Ask for the contractor's registration number(s) and confirm the category matches your works with the CIA (ciamauritius.org)
- Ask for the company BRN and check the firm is live on the Corporate and Business Registration Department register
- Confirm who invoices you — and, if you need a VAT invoice, that the invoicing entity is VAT-registered
- Ask for two referenced, comparable completed projects
- Get the scope, price and programme in writing before anyone mobilises
Any competent contractor will produce all five without hesitation. Ours are published: BFC Ltd, BRN C26230342, registered in the three categories above, with VAT invoicing available through sister company BFS Ltd (VAT 28513640) — stated on our home page and in every quotation.
Registration is the floor, not the ceiling
CIA registration proves a firm may do the work — not that it will do it well. Beyond the register, weigh the qualifications of the people actually running the job, the quality of the written quotation (a real bill of quantities versus one mystery line), and whether the firm inspects before it prices. Our approach to scoping and delivery is described under project management and technical inspection and audit.

Frequently asked questions
What is the CIA in Mauritius construction?
The Construction Industry Authority is the statutory body regulating the Mauritian construction industry, operating under the Ministry of National Infrastructure. It replaced the Construction Industry Development Board (CIDB) in June 2024 under the CIA Act 2023, merging the CIDB with the Building Control Advisory Council, and maintains the official register of contractors and consultants by category of works.
Is CIDB registration still valid in Mauritius?
Registrations issued under the former CIDB regime remain in use with their original numbering, but the register is now administered by the Construction Industry Authority. When checking a contractor, verify the registration and its works category with the CIA rather than the former CIDB.
How do I check if a contractor is registered with the CIA?
Ask the contractor for their registration number and confirm the category matches your works, then verify with the Construction Industry Authority (ciamauritius.org). Pair this with a check of the company's BRN on the Corporate and Business Registration Department register to confirm the firm is a live legal entity.
Can a building contractor also do my electrical works?
Only if they hold the appropriate registration for mechanical, electrical and plumbing works. MEP is a separate registration category from building construction, and a general builder informally covering the electrics is a common and avoidable risk.
