CIDB registration places your construction business on the Construction Industry Development Board Register of Contractors and gives it a grading designation. That grading is what national, provincial and municipal departments and state owned enterprises use to decide whether your tender will even be considered for a particular construction works contract. No CIDB registration, no public sector construction work.
The Construction Industry Development Board is a national body, established under the CIDB Act, that regulates and develops the construction industry. Every contractor that wants to tender for public construction must be registered and correctly graded. Your grade, from 1 at entry level to 9 with no upper limit, caps the value of the contracts you may bid for.
This page explains what CIDB is, who must register, how the grade 1 to 9 grading system works, the requirements, how to do the CIDB online application step by step, what it costs, how long it takes, the documents you will need, and how renewal works. If you would rather not navigate it alone, Insika can manage the whole CIDB registration on your behalf.
What is the CIDB and the Register of Contractors
The Construction Industry Development Board (cidb) is the national regulator for the construction sector. One of its core jobs is to keep the Register of Contractors, a public database of construction businesses that have been assessed and given a grading designation. Government bodies are required to use this register when they award construction work, so the register is the gateway to public sector tenders.
Two things make up your entry on the register:
- A grade, from 1 to 9, which reflects your financial and works capability and caps the contract value you may tender for.
- A class of construction works, such as General Building or Civil Engineering, which says what kind of work you are graded to do.
Together these form your grading designation, written as a number plus a class code, for example 4GB (grade 4, General Building) or 6CE (grade 6, Civil Engineering). You can be registered in more than one class if you can show capability in each.
Who must register with the CIDB
You must be registered on the CIDB Register of Contractors if you want to tender for or carry out construction works for the public sector. In practice this covers a wide range of businesses:
- Building contractors and sub-contractors bidding for state work.
- Civil engineering, road, water and infrastructure contractors.
- Electrical, mechanical and specialist works contractors who tender to government.
- New SMME and start-up contractors who want to enter the public construction market at grade 1.
Before you can register a contractor, the business itself must exist as a legal entity. Most applicants register a company with the Companies and Intellectual Property Commission first. If you have not done that yet, see our company registration service, then come back to CIDB. A sole proprietor using an identity number can also register at the lower grades.
CIDB grading explained: grades 1 to 9
The CIDB grading system runs from grade 1 to grade 9. Your grade is set by two things: your works capability (the largest contract you have completed in your class of works in the last five years) and your financial capability (your best annual turnover and the available capital you can put behind a contract). The higher of what your track record and finances support is what you can be graded at.
Each grade caps the value of the public construction contract you may tender for. The table below shows the indicative tender value limits and the track record commonly required to reach each grade. Confirm the current figures with the cidb, as they are reviewed from time to time.
| Grade | Maximum tender value | Indicative track record over 5 years |
|---|---|---|
| 1 | Up to R500 000 | None required (entry level) |
| 2 | Up to R1 000 000 | About R130 000 |
| 3 | Up to R3 000 000 | About R450 000 |
| 4 | Up to R6 000 000 | About R900 000 |
| 5 | Up to R10 000 000 | About R1 500 000 |
| 6 | Up to R20 000 000 | About R3 000 000 |
| 7 | Up to R60 000 000 | About R9 000 000 |
| 8 | Up to R200 000 000 | About R30 000 000 |
| 9 | No upper limit | About R90 000 000 |
Classes of construction works
Your grade always comes with at least one class of construction works, which describes the type of work you are graded to do. The two main categories are General Building and Civil Engineering, with several specialist classes alongside them. Common class codes include:
- GB - General Building.
- CE - Civil Engineering.
- EB - Electrical Engineering Works (Building).
- EP - Electrical Engineering Works (Infrastructure).
- ME - Mechanical Engineering.
- SB, SD, SE, SF, SG, SH, SI, SJ, SK, SL, SM, SN, SO, SQ, SS - specialist works such as demolition, glazing, landscaping, road markings, structural steelwork, water and waste treatment, and similar.
You pay the assessment fee for each class you apply for, and you must show track record in each class you want to be graded in. A contractor can hold different grades in different classes, for example 6CE and 4GB, if the track record supports each.
CIDB registration requirements
The exact requirements depend on the grade and class you apply for, but the core of what the cidb expects is consistent. To register, you generally need:
- A registered legal entity. A company registered with the Companies and Intellectual Property Commission (CIPC), a close corporation, a partnership, or a sole proprietor identified by ID number.
- A valid tax position. A SARS tax clearance or confirmation that the entity is registered and compliant for tax. See our tax clearance service.
- Financial information, for grades 2 to 9. This means annual financial statements or management accounts showing turnover, and evidence of available capital or financial sponsorship to back a contract.
- Works track record, for grades 2 to 9. Proof of the largest construction contract you have completed in your class, in the last five years, supported by award letters, completion certificates and payment certificates.
- Identity and authority documents for the owners, members or directors.
Grade 1 is deliberately lighter. It needs no completed projects and no financial history, only the entity, tax and identity details, which is why it is the standard starting grade for new contractors.
How to register on the CIDB step by step
CIDB registration is done through the cidb online registration system. The route is broadly the same for every grade, although grades 2 to 9 require more financial and track record evidence than grade 1. This is how a typical CIDB online application runs.
- Register your entity and get tax compliant
Make sure the business is a registered legal entity (CIPC company, close corporation, partnership or sole proprietor) and that it is registered and compliant with SARS. You cannot complete a CIDB registration without these in place.
- Decide your grade and class of works
Work out which class or classes you want to be graded in (for example GB or CE) and the grade your finances and track record support. New contractors usually start at grade 1. Apply for the grade you can prove, not the one you hope for, to avoid a downgrade or rejection.
- Create a profile on the CIDB online system
Register an account on the cidb online registration portal and capture the business and contact details. On the declaration, the designation field is the position you hold in the company, for example Director or Member.
- Complete the application and upload documents
Complete the relevant application (Grade 1, or Grade 2 to 9) and upload the supporting documents: company and tax documents, identity documents, and for grades 2 to 9 your financial statements and proof of completed contracts.
- Pay the assessment fee per class
Pay the cidb application and assessment fee. The fee is charged for each class of works you apply for and is non-refundable, so make sure your evidence is complete before you submit.
- Assessment, grading and certificate
The cidb assesses your financial and works capability, verifies your track record, and issues your grading designation. Once registered, you appear on the public Register of Contractors and receive your CIDB registration certificate, which you can then use when you tender.
How much does CIDB registration cost
The CIDB registration fee depends on the grade you apply for and is charged per class of construction works. Grade 1 is a low, once-off application fee with no annual fee, while the higher grades carry a larger application fee plus an annual amount tied to the grade. The figures below are indicative for budgeting and are not Insika prices. Always confirm the current tariff with the cidb.
| Grade | Indicative fee |
|---|---|
| Grade 1 | Around R450 per class, valid 3 years, no annual fee |
| Grade 2 | Application around R450 per class, with a smaller annual amount |
| Grades 3 to 9 | Application around R750 per class, plus an annual amount that scales with the grade |
| Annual amount (higher grades) | Scales up to tens of thousands of Rand at grade 9 (verify with the cidb) |
How long does CIDB registration take
A realistic expectation is about 5 to 30 working days from a complete, correctly compiled application to a grading decision. Grade 1 is usually the quickest because it needs no financial or track record verification. Grades 2 to 9 take longer because the cidb verifies your turnover and completed contracts.
- Faster: a grade 1 application, or a higher grade with clean, complete financial and track record evidence.
- Slower: missing documents, track record that cannot be verified, or queries that send the application back to you.
The single biggest factor in your favour is a complete first submission. Every missing certificate or unclear figure adds a round trip and pushes the date out.
Documents you will need
The exact list depends on the grade and class, but most CIDB applications call for the documents below. Grade 1 needs only the entity, tax and identity items, while grades 2 to 9 add the financial and track record evidence.
CIDB renewal and upgrading your grade
CIDB registration is not once-off. Your grading is valid for a set period and must be renewed to stay on the register. Grade 1 is valid for three years. Higher grades are renewed on a cycle and require you to requalify, by submitting up to date financial and track record information, so your grade still reflects your capability.
Renewal also gives you the chance to upgrade your grade. As your turnover grows and you complete larger contracts, you can apply to move up, say from 4GB to 5GB, by submitting the financial statements and completed contract evidence that support the higher grade. You can also add new classes of works at renewal or by a separate application.
If you let your registration lapse, you fall off the active register and cannot tender for public work until you reinstate it. Diarise your renewal date and start the requalification before it expires, especially if you are also upgrading, because the verification takes time.
