The answer is grade 3, and that is the easy half. What cidb grading you need for a R2 million contract has two halves, and most contractors check only the first. The grade must be the one whose published tender value range contains R2 million. The class of works code next to it must match the scope.
Get the digit right and the letters wrong and you are not registered for that job. The register says so, the client's search says so, and no amount of current registration fixes it.
The digit is a band, and the band is published
A cidb grading is a number and a code read together. The number sets the tender value the firm may take on. The code sets the kind of work it may take on, which is why the record reads as a pair rather than a level.
On the cidb's current grading table, grade 2 tops out at R1 million and grade 3 at R3 million. A R2 million contract sits inside grade 3, and a grade 3 registration in the right class of works is what a client's compliance check is looking for. Getting there is not only the ceiling: grade 3 also asks for a track record of R450 000, annual turnover of R1 million and available capital of R100 000. The cidb's August 2019 memo on the value ranges adds that at grades 3 and 4 the track record is required plus at least one of the turnover or capital figures. The current table does not repeat that note.
Be careful with the rest of that memo, though. It printed higher qualifying figures, a R675 000 track record for grade 3 among them, and a later cidb clarification communique replaced them, saying the requirements to qualify had not changed. The R450 000, R1 million and R100 000 on the current table are the communique's figures.
Check which R2 million you mean before you rely on that. The ceilings are inclusive of VAT, so the figure to compare is the tender sum with VAT on it. A job you think of as R2 million excluding VAT is R2,3 million to the register. Still grade 3, comfortably, but the habit of comparing the wrong number is how a firm near a boundary gets it wrong.
Both halves of your designation sit on your record at portal.cidb.org.za, which takes a contractor name or a CRS number, and filters on province, city, status, designation and class of work. That is the page a client uses. It is also the page you should be reading about your own firm before you price anything.
The value ranges are set in South Africa's Construction Industry Development Regulations and are adjusted from time to time. The current ranges came in through an adjustment gazetted in July 2019 and effective from 7 October 2019, which lifted grade 3 from a R2 million ceiling to R3 million. Note what that means for this question: on the old table R2 million was the top of grade 3, and on the new one it sits comfortably inside it. The answer happens to survive the change. Most numbers do not.
Which is why it is worth knowing that the cidb's own site does not agree with itself. Its grading designation calculator still explains the system using a pre-2019 example, a 5CE registration considered for civil engineering work "not exceeding R6.5 million", while its requirements-for-grading table puts grade 5 at R10 million. The R6.5 million is the old grade 5 ceiling: the cidb's August 2019 memo lists grade 5 moving from R6 500 000 to R10 000 000. The calculator's example was simply never updated.
Read the band off the regulation and the current table, not off a forum answer, a calculator's worked example, or a tender briefing note from three years ago. A stale band is how a contractor talks himself into a bid he is not entitled to make.
What is the most common cidb grading problem?
The most common grading problem is a contractor bidding outside their class of works, not above their value ceiling.
A firm can be entirely current on the register, in good standing, with a grade comfortably above the contract value, and still sit outside its designation for the scope on the table. To a client running a compliance check, that reads exactly like a registration failure. It is the flag that gets the least explanation and causes the most damage.
The reason it happens is that the work drifts and the record does not. A firm registered for general building picks up two years of civils work through a friendly main contractor. Nothing about the register moves, because nobody told it to. Then a client checks the designation against the scope, and the answer on screen does not match the answer in the tender document.
The register stopped taking overstated grading on trust
Grading used to be the quiet part of registration. It is not any more.
The latest notice on the cidb's blacklisted contractors page, read on 2 November, removes 12 contractors from the register with effect from 24 July 2026, under regulation 30(2) of the Construction Industry Development Regulations. The stated grounds include breaching the requirements and conditions of registration, "including the submission of fraudulent documents as evidence of their track record for grading purposes".
That notice is not a one-off. The page files it under July 2026 and lists earlier rounds beside it, filed under April 2026, November 2025 and October 2025. Public Works announced further removals on 27 October 2026, which the page did not yet list. This is a standing process now, not an incident.
Read that phrase again, because it is the enforcement edge of this exact question. Track record is what a grading application is built on, and overstating it is now a removal ground with a gazette notice attached.
The direction is confirmed from above. Public Works and Infrastructure Minister Dean Macpherson spoke at SIDSSA 2026 on 25 August 2026. Only two contractors were removed for fraudulent conduct in the cidb's first 22 years, he said, against 52 in the 22 months to that date. Those are his numbers from one speech, and the cidb publishes no running total of its own. Even discounted, they describe a register that has started acting.
What the client is buying when they ignore it
Clients do ignore it, and the reason is ordinary. The price is good, the firm has done work for them before, and the grading question feels like administration.
What they are actually buying is a contract that becomes difficult to enforce at the worst possible moment. A contractor appointed outside its registration is exposed on the appointment itself, and the client's remedies get complicated exactly when the job has gone wrong and they need those remedies to be simple.
We see the mismatch from the other side, because we check the grading and the class of works against the scope before a client ever sees a contractor. The pattern is consistent, and it looks like this.
A firm holding 2GB quotes the R2 million job, when its ceiling is R1 million and the work needs grade 3. Or, more often, a firm holding a perfectly adequate 3GB quotes a R2 million package that is civil engineering work, and general building is the only class of works on its record. Then a client accepts the quote because the number is attractive. Then an appointment nobody can rely on when a defect appears in month seven.
Arabella verifies that pairing once and keeps it current, which is described on the contractor page. The register notices we read each week are collected in insights.
On Monday
Open your own record on the register and write down both halves. The grade, and every class of works code listed beside it.
Then take the last three tenders you priced and put the scope of each next to that list. Not the value, the scope. If any of the three sits outside a code you actually hold, you have either an upgrade application to lodge or a bid you should not have made. Either way it is cheaper to find out now than at award.
