CIDB Contractor Registration: Grades, Requirements, and How to Apply
The Construction Industry Development Board (CIDB) is the statutory body that regulates and grades construction contractors in South Africa. If you want to bid on any government construction tender, your company must be registered with CIDB at the appropriate grade for the contract value you are pursuing. This guide explains the CIDB grading system, the requirements for each grade, and how to register or upgrade.
CIDB Grades and Contract Value Thresholds
CIDB grades run from Grade 1 (entry level) to Grade 9 (unlimited). Each grade is associated with a maximum contract value that the registered contractor can bid on. The grades and thresholds are periodically adjusted. Current thresholds range from Grade 1 (up to R200,000) through Grade 9 (unlimited). Most SME construction companies start at Grade 2 or 3 and build up their track record and financial capacity over time to qualify for higher grades.
In addition to the main grading, CIDB also classifies contractors by work class: CE (Civil Engineering), GB (General Building), EB (Electrical), ME (Mechanical), and SI (Specialist Works). You must be graded in the specific work class relevant to the contract being tendered. A Grade 5 CE contractor, for example, can bid on civil engineering contracts up to R20 million, but cannot bid on electrical works contracts without a separate EB grading.
- Grade 5: up to R20 million (common for SME contractors)
- Grade 6: up to R65 million (infrastructure and larger projects)
- Grade 7: up to R200 million (large contractors)
- Work class designation required: CE, GB, EB, ME, or SI
Financial and Track Record Requirements
CIDB grading is assessed on two primary factors: financial capability and track record. Financial capability is measured by annual turnover, net asset value (from audited financials for Grade 4 and above), and available capital. Track record is assessed by contracts successfully completed at or above the threshold for your current grade, with proof such as completion certificates, letters of appointment, or engineer's final accounts.
For Grades 1 to 3, financial assessment is simpler and bank statements may be sufficient. For Grade 4 and above, CIDB requires full audited financial statements not older than 18 months. For Grade 7 and above, the financial requirements are substantial — annual turnover in the hundreds of millions of rand. Companies planning to upgrade their grade should ensure their financial records are in order and that completed projects are properly documented well in advance of the application.
- Grades 1-3: bank statements and simple financial proof
- Grades 4+: audited financial statements required
- Track record: completion certificates from past projects

Frequently Asked Questions
Can a joint venture bid at a higher CIDB grade than either partner?
Yes, a CIDB-registered joint venture can be graded higher than either individual partner based on the combined financial capacity and track record of the JV. Joint ventures must be registered with CIDB before submitting a bid. The JV registration is separate from the individual company registrations.
How long is a CIDB grading certificate valid?
CIDB grading certificates are valid for three years from the date of registration or most recent upgrade assessment. Contractors must submit a renewal application before expiry to maintain their grade. If a certificate expires, the contractor cannot legally bid on contracts above Grade 1 until it is renewed.
