How to Start a Construction Company in South Africa
Here's everything you need to register your Construction Company, stay compliant, and hit the ground running.

Why Start a Construction Company?
South Africa's growing need for housing, infrastructure, and development makes construction a high-demand industry. Starting a construction company can be a profitable and scalable business with opportunities in both private and government sectors. With the right compliance in place, you can take on larger contracts and build a trusted brand in your area.

Step 1: Price the work before you register
Construction businesses fail on price, not on skill. Before registering anything, work out your day rates for artisans and general workers, what plant hire costs in your area, and who you will actually quote: homeowners, main contractors, or municipalities. Put it on one page. The free business plan generator drafts the structure; the numbers must be yours.
Step 2: Register your construction company
A registered Pty Ltd gets you a registration number, the CoR 14.3 certificate, and an income tax number. Everything that follows starts with these documents: the business bank account, CIDB registration, and every tender pack you will ever submit.
Step 3: Register for tax and get a tax clearance PIN
The company's income tax number is issued with registration. What buyers actually check is your Tax Compliance Status, the TCS PIN from SARS. You will need it for the CSD, for most tender packs, and when a main contractor vets you as a subcontractor.
Step 4: Get your B-BBEE affidavit
Under R10 million a year in turnover, your company is an Exempt Micro Enterprise: no scorecard audit, just a sworn affidavit. A 100% black-owned EME qualifies as Level 1. Tender evaluations and main contractors' procurement teams ask for the affidavit, and it costs nothing to have ready.
Step 5: Register with the CIDB and get graded
Every public-sector construction contract requires CIDB registration, and private developers increasingly ask for it too. New contractors start at Grade 1, which covers projects up to R500,000; higher grades need a track record and available capital. Check what grade your history supports with the free CIDB grade calculator, then register.
Step 6: Register with the NHBRC before building homes
If you build homes, NHBRC registration is not optional: every home builder must register, and every new home must be enrolled before construction starts. Banks will not release mortgage funds on an unenrolled home. Commercial and civils work does not need it.
Step 7: Register for COIDA and get a letter of good standing
One injury on site without COIDA registration is an uninsured claim against the company. Register with the Compensation Fund as soon as you employ anyone, and keep the letter of good standing current: main contractors will not let a subcontractor on site without it, and it lapses every year.
Step 8: Get onto the Central Supplier Database (CSD)
The Central Supplier Database is National Treasury's register of everyone allowed to supply the state. Municipal maintenance work, school renovations, provincial projects: all of it requires a CSD number on the tender cover sheet. Registration itself is free at Treasury; Govchain handles the application and the tax and banking verifications that usually trip it up.
Step 9: Fund the first months
Rent plant rather than buying it, until the order book forces your hand. The cost that sinks new contractors is wages and materials in the weeks before the first payment certificate clears; budget for at least a month of both. For equipment finance and grant routes, see the government funding guide.
Step 10: Win your first construction contracts
Most new contractors' first work is subcontracting for a graded main contractor: lower margin, but it builds the track record that CIDB grading and references need. Watch the eTender portal and CIDB iTender, introduce yourself to site agents, and have a one-page company profile ready with your registration numbers on it. Govchain generates one free.
