If you want to bid on government or state-owned-enterprise construction work, you must be on the CIDB Register of Contractors. Grade 1 costs R450 per class of works, is activated within 48 working hours, and lets you tender on contracts up to R500,000 including VAT. Higher grades unlock bigger contracts but demand a proven track record. Here is how the system works and how to climb it.
What the CIDB is
The Construction Industry Development Board (cidb.org.za) runs two registers. The Register of Contractors (RoC) is your company's listing, grade and compliance status, visible to every public-sector client. The Register of Projects (RoP) is a database of construction contracts above R100,000 that the principal contractor must enrol before work starts. Projects on the RoP are the evidence that later upgrades your grade, so a finished project that was never enrolled cannot count towards your track record.
Registration is not legally required for purely private work, but many developers, main contractors and insurers use it as a pre-qualification benchmark, and Grade 1 is cheap and quick, so most tradies register anyway.
The grading bands (current, VAT inclusive)
Your grade caps the tender value you may bid:
- Grade 1: up to R500,000, no track record required.
- Grade 2: up to R1 million.
- Grade 3: up to R3 million.
- Grade 4: up to R6 million.
- Grade 5: up to R10 million.
- Grade 6: up to R20 million.
- Grade 7: up to R60 million.
- Grade 8: up to R200 million.
- Grade 9: no limit.
You may still see Grade 1 quoted as R200,000 in older material; that is the old band. A contractor with PE (Potentially Emerging) status may be allowed to bid one grade higher than its registered grade.
Your grade is set by the lowest of three factors: your best annual turnover from the two preceding financial years, your available capital (liquid assets minus liabilities), and your works capability, meaning the largest single contract you completed in that class in the last 5 years and enrolled on the RoP.
Classes of works
Your grade applies per class, and you register separately for each: GB (General Building), CE (Civil Engineering), EB and EP (Electrical Engineering, building and projects), ME (Mechanical Engineering) and SB (Specialist Building Works). A general builder registers GB; many small firms register GB and CE together.
How to register
Applications are online at cidb.org.za:
- Create a CIDB CIMS portal account (email verification required).
- Complete the application: company details, class of works, directors' IDs, financials.
- Upload documents: CIPC certificate (CoR14.3), certified director IDs, a valid SARS Tax Compliance Status (TCS) PIN, your CSD supplier number (the MAAA number), share certificates for a Pty Ltd, and for Grade 4 and up, audited financial statements plus proof of completed RoP projects.
- Pay the fee. Grade 1 costs R450 per class of works, once-off and non-refundable, so GB plus CE at Grade 1 is R900.
- Grade 1 is activated within 48 working hours. Higher grades go through CIDB assessment, so allow 4 to 8 weeks.
For Grades 2 to 9 the published fee information conflicts (the CIDB has referred to an admin fee plus annual renewal fees, while other sources quote per-three-year amounts), so confirm the current fee schedule on cidb.org.za before you budget.
Registration is valid for 3 years, expiring on the last day of your anniversary month. A lapsed registration means immediate removal from the RoC and disqualification from tenders, so renew at least 3 months early.
How to grade up
To move up you must show the financial capacity for the new grade and at least one completed project in the relevant class, within the last 5 years, enrolled on the RoP, at the value the new grade requires. Then submit a regrading application on the portal. The practical rule: enrol every project on the RoP as you go, even small jobs below the mandatory R100,000 threshold (voluntary enrolment is allowed), because that record is your ladder.
Worked example: bidding a R2 million municipal job
A municipal refurbishment worth R2,000,000 (VAT inclusive) in the GB class needs Grade 3, which covers up to R3 million. For Grade 3 you need turnover in one of the past two years of roughly R1.5 million to R2 million, available capital to match, and a single completed GB contract of R450,000 or more on the RoP. The blocker for most emerging contractors is that one R450,000 RoP project, which is exactly why you enrol everything from day one.
Common mistakes
- Not enrolling projects on the RoP. No record, no upgrade, stuck at Grade 1.
- Mismatched class of works. A GB contractor bidding a CE tender is rejected even at the right grade.
- Letting registration lapse. Instant disqualification; renew 3 months before expiry.
- No live CSD number. The CIDB portal needs your MAAA number to sync (see Tenders 101).
- Management accounts above Grade 3. Grade 4 and up requires audited financials, no exceptions.
- Counting bank loans as capital. Available capital means net assets, shareholder loans and retained earnings.
