If you’re planning to undertake construction work in Mauritius valued at over Rs 1 million, registering with the Construction Industry Authority (CIA) isn’t just recommended—it’s legally required.
This comprehensive guide walks you through everything you need to know about contractor registration in 2025, including recent changes that have transformed the landscape of construction industry regulation in Mauritius.
What is the Construction Industry Authority (CIA)?
The Construction Industry Authority represents a significant evolution in Mauritius’s construction sector regulation.
Following the passage of the Construction Industry Authority Act 2023 in Parliament in November 2023, the former Construction Industry Development Board (CIDB) officially transitioned to the CIA in June 2024.
This transformation merged the CIDB with the Building Control Advisory Council, creating a more comprehensive regulatory body with expanded responsibilities.
The CIA’s mandate extends beyond simple contractor registration. It now encompasses building control functions, promotes green building practices and sustainability initiatives, oversees the implementation of ESG (Environmental, Social, Governance) principles in construction, and continuously updates building codes and standards to align with international best practices.
Who Needs to Register?
According to Section 19 of the Construction Industry Authority Act 2023, no local contractor shall undertake construction works in Mauritius unless they are registered under the Act and hold a valid Building and Land Use Permit for the construction works to be undertaken.
However, there’s an important threshold to understand. As of 2025, contractors undertaking projects valued at less than Rs 1,000,000 (VAT exclusive) are classified as micro-contractors and are exempt from mandatory CIA registration.
This represents a significant increase from the previous Rs 500,000 threshold, providing relief for small-scale contractors and home improvement professionals.
If your construction work exceeds this threshold, registration is non-negotiable. Operating without proper registration can result in legal penalties, contract invalidity, and barriers to accessing larger projects and government tenders.
Understanding Contractor Grades and Classes
The CIA has simplified its grading system to make it more accessible and easier to understand. Contractors are now classified into four grades, ranging from Large to Small. Each grade corresponds to a maximum contract value that the contractor is legally permitted to undertake.
Attempting to execute projects beyond your registered grade limit is prohibited and can result in serious consequences.
The grade system ensures that contractors possess adequate financial capacity, technical expertise, and experience commensurate with the scale of projects they undertake.
As your business grows and demonstrates consistent performance, you can apply for grade upgrades to access larger, more lucrative contracts.
Equally important are the classes of works, which have expanded from three to six categories.
Contractors can now register under Building Construction Works, which covers residential, commercial, and institutional structures; Civil Engineering Construction Works, encompassing roads, bridges, drainage, and infrastructure; Mechanical, Electrical and Plumbing Works (MEP), for integrated building services; Mechanical Works as a standalone category; Electrical Works as a separate specialty; and Specific Works, covering specialized construction activities.
A single contractor can register for multiple classes and multiple grades across different classes, allowing for diversification and specialization based on your company’s capabilities and business strategy.
The Registration Process: Step by Step
The CIA has modernized its registration process with an e-registration platform, making it significantly easier to submit applications and track their progress. Here’s how to navigate the process successfully.
Step 1: Determine Your Registration Category
First, identify whether you’re applying as a local contractor, foreign contractor, or joint venture.
Local contractors use Form RG6, while foreign contractors and joint ventures use Forms RG7 through RG10 depending on their specific circumstances. If you’re seeking registration for miscellaneous construction items, you’ll need Form RG20.
Step 2: Assess Your Eligibility
Before beginning your application, carefully review the criteria for registration. The CIA publishes detailed requirements in the “Criteria for Registration & Upgrading of Contractors” document, which outlines financial thresholds, equipment requirements, technical personnel qualifications, and experience documentation needed for each grade and class.
Pay close attention to the Grade Ceiling document, which specifies the maximum contract values for each grade.
Understanding these limits from the outset will help you apply for the appropriate grade that matches both your current capabilities and business ambitions.
Step 3: Gather Required Documentation
Preparation is crucial for a smooth registration process. You’ll typically need company registration documents including your Business Registration Certificate or Certificate of Incorporation, tax compliance certificates demonstrating good standing with the Mauritius Revenue Authority, audited financial statements for the past two to three years (depending on the grade), proof of equipment ownership or access to necessary construction equipment, evidence of technical personnel qualifications and experience, documentation of completed projects with contract values and client references, and insurance certificates covering professional indemnity and workers’ compensation.
The exact requirements vary by grade and class, so consult the Notes to Applicants documents (RG6 through RG10) specific to your registration category.
Step 4: Complete the Online Application
Access the CIA’s e-registration platform at https://cidbregistration.govmu.org/. Create an account or log in if you already have one, then select the appropriate registration form for your category.
Fill out all required fields accurately and completely—incomplete applications will be rejected and delay your registration. Upload all supporting documents in the specified formats, typically PDF, and ensure file sizes comply with the platform’s requirements.
Review your application thoroughly before submission, as errors can significantly extend processing times.
Step 5: Pay Registration Fees
Upon submission, you’ll receive instructions for paying the applicable registration fees. Fees vary based on the grade and number of classes you’re registering for.
Payment can typically be made through bank transfer or online payment systems. Retain your payment receipt, as you’ll need it for reference and follow-up.
Step 6: Application Review and Site Inspection
Once submitted, your application enters the CIA’s review process. An evaluation panel assesses your documentation against the established criteria.
For certain grades and classes, the CIA may conduct a site inspection to verify equipment, office facilities, and operational capacity. Be prepared to demonstrate that the resources you’ve claimed in your application are actually available and functional.
The review process can take several weeks to months, depending on the complexity of your application and the CIA’s workload. During this period, the CIA may request additional information or clarification. Respond promptly to any such requests to avoid delays.
Step 7: Receive Your Registration Certificate
If your application is approved, you’ll receive a Registration Certificate specifying your grade(s), class(es), and registration validity period. This certificate must be prominently displayed at your business premises and may need to be presented when bidding for projects or dealing with clients.
Registration certificates are typically valid for one year and must be renewed annually. Mark your renewal date on your calendar, as allowing your registration to lapse can complicate ongoing projects and future contract opportunities.
Upgrading Your Registration
As your business grows, you’ll likely need to upgrade your registration to access larger projects. The process for upgrading uses Form RG19 (Application for Upgrade of Registration & Addition of Specific Works).
To qualify for an upgrade, you must demonstrate successful completion of projects at or near your current grade ceiling, improved financial standing with audited statements showing increased turnover and working capital, acquisition of additional equipment or technical personnel as required for the higher grade, and maintenance of good standing with no outstanding issues or complaints.
Timing your upgrade application strategically can be important. Apply when you have strong recent projects to showcase and when your financial statements reflect your company’s growth trajectory. Don’t wait until you urgently need the higher grade for a specific project, as the approval process takes time.
Special Considerations for Foreign Contractors and Joint Ventures
Foreign contractors face additional requirements when seeking to operate in Mauritius. The CIA offers two types of registration for foreign entities: Provisional Registration, which is project-specific and tied to a particular contract, and Temporary Registration, which allows for multiple projects within a defined period.
Foreign contractors typically need to demonstrate equivalent registration or licensing in their home country, experience with projects of similar scope and complexity, financial capacity appropriate to Mauritian market standards, and often a partnership or arrangement with a local entity.
The terms and conditions for foreign contractor registration are more stringent and include specific obligations regarding local employment, technology transfer, and compliance with Mauritian construction standards.
Joint ventures between local and foreign contractors or between multiple local contractors also require special registration.
These arrangements can provide an effective pathway for smaller local contractors to access larger projects by partnering with more established firms.
Joint venture registrations can be either provisional (project-specific) or temporary (time-bound), with distinct terms and conditions for each category.
Common Mistakes to Avoid
Many contractors encounter delays or rejections due to preventable errors. Avoid these common pitfalls by ensuring all documentation is current and not expired, as outdated tax certificates or insurance policies will cause immediate rejection.
Don’t underestimate the equipment and personnel requirements—these are verified, and exaggeration will be discovered. Be realistic about your grade application; applying for a grade beyond your demonstrated capacity wastes time and money.
Keep meticulous records of past projects with verifiable documentation, as the CIA may contact your previous clients.
Don’t ignore the Building and Land Use Permit requirement—CIA registration alone is not sufficient to commence work. Finally, start your renewal process well before expiration; last-minute renewals risk lapses that can jeopardize ongoing projects.
Maintaining Your Registration
Registration is not a one-time event but an ongoing commitment. To maintain good standing with the CIA, you must renew annually before your certificate expires, update your information promptly when there are changes to ownership, key personnel, or company structure, comply with all CIA regulations and reporting requirements, maintain the financial and technical standards required for your grade, and respond to CIA inquiries or audits in a timely and comprehensive manner.
Contractors who consistently maintain high standards and demonstrate professional conduct build credibility that can facilitate faster processing of upgrades and renewals.
The Benefits of Proper Registration
While the registration process requires effort and investment, the benefits are substantial. Registered contractors gain legal authorization to bid on and execute projects above the Rs 1 million threshold, access to government and institutional projects that require CIA registration as a prerequisite, enhanced credibility with clients who view registration as a mark of legitimacy and capability, eligibility for bank financing and bonding facilities that are often restricted to registered contractors, participation in CIA training programs and industry development initiatives, and protection under the CIA’s dispute resolution mechanisms.
Moreover, as Mauritius’s construction industry continues to modernize and professionalize, the distinction between registered and unregistered contractors will become increasingly pronounced. Early adoption of proper registration positions your business for long-term success.
Resources and Support
The CIA provides numerous resources to assist contractors through the registration process. The official website (www.cidb.mu or www.ciamauritius.org) contains all current forms, criteria documents, and guidelines.
You can download the most recent versions of registration forms, criteria for registration and upgrading, grade ceiling schedules, notes to applicants for each form, and terms and conditions for different contractor categories.

Looking Ahead: The Future of Construction Regulation in Mauritius
The transition from CIDB to CIA represents more than a name change—it signals Mauritius’s commitment to elevating construction industry standards and practices.
The expanded mandate of the CIA suggests that contractors should prepare for increased emphasis on sustainable building practices and green construction methods, stricter enforcement of building codes and quality standards, greater integration of digital tools and building information modeling, enhanced focus on worker safety and welfare, and alignment with international construction industry best practices.
Contractors who proactively embrace these trends, invest in upgrading their capabilities, and maintain exemplary compliance records will be best positioned to thrive in Mauritius’s evolving construction landscape.
Conclusion
Registering with the Construction Industry Authority is a fundamental step for any serious contractor in Mauritius. While the process requires careful preparation and documentation, the CIA’s modernized systems and clearer grading structure have made registration more accessible than ever.
By understanding the requirements, preparing thorough applications, and maintaining ongoing compliance, contractors can secure the credentials needed to grow their businesses and contribute to Mauritius’s construction sector.
Whether you’re a new contractor seeking your first registration or an established firm planning an upgrade, this guide provides the foundation for navigating the CIA registration process successfully. Take the time to review the official criteria documents, gather your documentation meticulously, and don’t hesitate to reach out to the CIA for clarification when needed.
Your CIA registration is more than a legal requirement—it’s your gateway to professional recognition, business growth, and participation in building Mauritius’s future infrastructure.
