CIDB grading explained: how contractors qualify for bigger tenders
If you're a contractor in South Africa and you want to tender for public-sector construction work, your CIDB grade is the single number that determines what you're allowed to bid on.
What the CIDB Register of Contractors is for
Any contractor can register on the CIDB Register of Contractors (RoC). Public-sector clients don't have a choice in the matter: under the Construction Industry Development (CID) Regulations of 2004, as amended, they may only award construction contracts to CIDB-registered contractors. If you want to work on government or public-entity construction projects, registration isn't optional — it's the entry ticket.
Not everyone needs to register, though. Subcontractors do not (yet) need to register; home builders are regulated by the NHBRC and are exempt from the CIDB register; and labour-only contractors are exempt.
The nine grades, and what a grading code means
The Register of Contractors uses 9 grading levels, with Grade 9 being the highest. There are no qualifying criteria for Grade 1 — anyone can register — while Grades 2 to 9 require meeting specific financial and track-record criteria.
A grade is expressed as a digit plus two letters — for example, “4GB” — showing both the maximum tender value you're certified for and the class of works you're certified in. A contractor seeking “emerging contractor” classification is designated with four letters instead, e.g. “4GBPE.”
| Grade | Tender value range (≤) |
|---|---|
| 1 | R500,000 |
| 2 | R1,000,000 |
| 3 | R3,000,000 |
| 4 | R6,000,000 |
| 5 | R10,000,000 |
| 6 | R20,000,000 |
| 7 | R60,000,000 |
| 8 | R200,000,000 |
| 9 | No limit |
Classes of works — the letters that follow your grade number
The letters in your grading code identify which type of construction work you're certified for. The main classes include General Building (GB), Civil Engineering (CE), Electrical Engineering Works – Building (EB), Electrical Engineering Works – Infrastructure (EP), and Mechanical Engineering (ME), alongside a long list of specialist classes covering areas like asphalt works, excavations, corrosion protection, demolition and blasting, fire prevention, glazing, landscaping, lifts and escalators, piling, road markings, structural steel, timber structures, waterproofing, water supply and drainage, and steel fencing or precast work. You can hold different grades in different classes — a contractor doesn't need to be graded identically across every type of work they do.
What actually determines your grade
CIDB assesses two things: your track record, and your financial capability.
Track record looks at projects you've completed in the last five years in the class of works you're applying for. Grade 2–9 applicants need a minimum “largest contract completed” value in that period:
| Grade | Max contract value capability | Min. track record (largest contract, past 5 yrs) |
|---|---|---|
| 1 | R500,000 | R0 |
| 2 | R1,000,000 | R130,000 |
| 3 | R3,000,000 | R450,000 |
| 4 | R6,000,000 | R900,000 |
| 5 | R10,000,000 | R1,500,000 |
| 6 | R20,000,000 | R3,000,000 |
| 7 | R60,000,000 | R9,000,000 |
| 8 | R200,000,000 | R30,000,000 |
| 9 | No limit | R90,000,000 |
Financial capability is assessed from your financial statements for the past two years, using the best annual turnover of the two:
| Grade | Best annual turnover required | Available capital required |
|---|---|---|
| 3 | R1,000,000 | R100,000 |
| 4 | R2,000,000 | R200,000 |
| 5 | R3,250,000 | R650,000 |
| 6 | R6,500,000 | R1,300,000 |
| 7 | R20,000,000 | R4,000,000 |
| 8 | R65,000,000 | R13,000,000 |
| 9 | R200,000,000 | R40,000,000 |
Grades 1 and 2 have no turnover or capital requirement. If you don't have the required capital on hand, a third-party financial sponsorship (a guarantee or surety) can substitute for it — though if the sponsor isn't a financial institution, its sponsorship can't exceed 15% of its own net asset value.
Fees
CIDB registration involves both an admin fee and, for most grades, an annual fee. CIDB explicitly notes that it “may review registration fees from time to time,” so treat these as current rather than fixed indefinitely.
| Grade | Admin fee | Annual fee |
|---|---|---|
| 1 | R450 | R0 |
| 2 | R450 | R250 |
| 3 | R750 | R350 |
| 4 | R750 | R900 |
| 5 | R750 | R1,750 |
| 6 | R750 | R3,500 |
| 7 | R750 | R9,000 |
| 8 | R750 | R29,000 |
| 9 | R750 | R55,000 |
Keeping your grade — the 3-year cycle and annual updates
A CIDB grade is valid for 3 years, expiring on your registration anniversary, at which point you apply for renewal. Within that 3-year period, though, your grade must be updated annually, with the applicable annual fee paid — annual updates don't apply to Grade 1.
The consequence of neglecting this matters: a grade that isn't updated for two consecutive years is suspended. A suspended grading can quietly disqualify you from tenders you'd otherwise be eligible for, so this isn't a filing to let slip.
Where and how to register
The process differs by grade level. Grade 1 can be registered entirely online, and is processed within 48 working hours. Grades 2–9 require an application at the nearest CIDB Provincial Office, with supporting documents, and carry a maximum processing time of 21 working days.
Joint ventures
If you're bidding as part of a joint venture (JV), the JV entity itself does not need to register separately with CIDB — but every JV partner must be individually registered, and a JV Calculator is used to determine the combined grading of the venture. This is a common trip point on larger tenders: all partners need their own registration in good standing before the JV's combined capability can even be calculated.
A proposed change worth watching — but not yet law
There's been ongoing discussion about a Construction Industry Development Board Amendment Bill, published for public comment in May 2024, which would — among other things — extend CIDB-style registration requirements to private-sector procurement, not just public-sector work, and introduce new administrative fines and criminal penalties for serious contraventions.
It is important to be clear about the status of this Bill: as of early 2026, independent legal commentary confirms it has not yet been promulgated. Public comment closed in November 2024, submissions have been consolidated, and the Bill must still pass through the Chief State Law Advisor's certification, possibly NEDLAC review, and Cabinet before it even reaches Parliament. In other words: this is proposed legislation, not current law. Private-sector clients are not yet required to only use CIDB-registered contractors, and the proposed fines and thresholds are not in force. We'll update this article if and when that changes — but for now, plan around the existing Act 38 of 2000 framework described above.
Key takeaways
- CIDB grading runs from 1 to 9, with Grade 1 open to any contractor and Grades 2–9 requiring track record and financial capability.
- Each grade sets a maximum tender value, from R500,000 (Grade 1) to no limit (Grade 9).
- Grades are valid for 3 years but must be updated annually; two missed annual updates trigger suspension.
- Grade 1 registers online in 48 working hours; Grades 2–9 go through a Provincial Office with a 21-working-day maximum.
- In a JV, every partner must be individually registered — the JV itself doesn't register separately.
- A CIDB Amendment Bill proposing private-sector registration and new penalties has been published for comment but is not yet law.
