CIDB Grade Requirements for Construction Tenders: 2025 Update
The Construction Industry Development Board (CIDB) is the regulatory body that grades construction companies in South Africa and determines which contracts they can legally bid on. CIDB grades range from Grade 1 (smallest, up to R200,000) to Grade 9 (unlimited contract value), and bidding outside your grade is grounds for immediate disqualification. In 2025, CIDB has updated several grading thresholds and introduced new requirements for contractor registration and grading assessment.
Updated CIDB Grading Thresholds for 2025
CIDB periodically revises the contract value thresholds associated with each grade to account for inflation and changes in the construction market. For 2025, the key thresholds for the most common grades are: Grade 1 (up to R200,000), Grade 2 (R200,001 to R650,000), Grade 3 (R650,001 to R2,000,000), Grade 4 (R2,000,001 to R6,500,000), Grade 5 (R6,500,001 to R20,000,000), Grade 6 (R20,000,001 to R65,000,000), Grade 7 (R65,000,001 to R200,000,000), Grade 8 (R200,000,001 to R650,000,000), Grade 9 (unlimited).
Companies should note that these thresholds apply to the contract value at time of award, not the tender estimate. If a contract is awarded at a value that exceeds your grade's threshold, you will be required to upgrade your grading before signing the contract. CIDB grading certificates are also required to be current at the time of tender submission, not just at award, so ensure your certificate has not expired before submitting a bid.
- Grade 5: up to R20 million — common entry point for SME contractors
- Grade 6: up to R65 million — infrastructure and facility management tenders
- Grade 7: up to R200 million — large public works projects
- Certificates must be valid at time of submission, not just at award
How to Upgrade Your CIDB Grade
Upgrading your CIDB grade requires demonstrating that you have successfully completed contracts at your current grade and that your financial capacity has grown accordingly. The CIDB assesses both track record (contracts completed within the past five years) and financial capacity (annual turnover, net asset value, and available capital). For grades 1 to 3, the requirements are relatively straightforward. For grade 4 and above, CIDB requires audited financial statements and a track record of completed works with contactable references.
The grading application process is managed through the CIDB online portal. Typical processing time for a grading upgrade is six to eight weeks, although this can vary depending on CIDB workload. Contractors should plan their grading upgrades well in advance of anticipated tender opportunities at the higher grade level. Urgency requests or expedited processing are generally not accommodated, so proactive planning is critical.
- Audited financial statements required for Grade 4 and above
- Track record of completed contracts at current grade level required
- Plan for six to eight week processing time for upgrades

Frequently Asked Questions
Can I sub-contract to a higher-grade contractor to bid above my grade?
No. The CIDB requirement applies to the main contractor submitting the bid. You cannot use a sub-contractor's grade to bid on contracts above your own grade. However, a higher-grade contractor can use your services as a sub-contractor on their bid.
What happens if my CIDB certificate expires during the tender evaluation period?
If your CIDB certificate expires after submission but before award, most government departments will require you to provide a renewed certificate before processing the award. However, some departments may disqualify bids where the certificate was not valid at the time of submission. Always submit with a certificate that has at least 60 days validity remaining.
