COIDA for Construction Companies: What Contractors Must Know
Quick Answer
COIDA for Construction Companies: What Contractors Must Know
Construction companies must register with the Compensation Fund like all employers – but pay higher tariffs because injury risk is higher, and cannot get onto most sites without a current Letter of Good Standing. Principal contractors can be held liable for uninsured subcontractors’ workers.
What this means in plain language
In construction, COIDA is checked constantly: tenders demand the letter, site agents demand it again at the gate, and principal contractors verify subcontractors because an uninsured subbie’s injured worker can become the principal’s problem.
Your tariff depends on your declared work class – roofing differs from painting. Declare honestly: a claim in the wrong class triggers reassessments and penalties.
Who this applies to
- Construction contractors and subcontractors of every size
- Principal contractors managing subcontractors on site
Step by step
- Register with the Compensation Fund before the first worker starts.
- Confirm your industry subclass so the correct tariff applies.
- File the Return of Earnings by 31 March every year without fail.
- Pay assessments on time and request the Letter of Good Standing.
- Collect and verify Letters of Good Standing from every subcontractor on your sites.
Common mistakes to avoid
- Letting casual day labourers work before registration – one injury makes you personally liable.
- Declaring under a cheaper subclass – claims expose the real work.
- Taking a subcontractor’s letter at face value – verify it with the Fund.
A South African example
A Rustenburg building contractor keeps a compliance file per site: its own Letter of Good Standing plus verified letters from the electrician, plumber and roofer. When an inspector arrives, the file answers every question in five minutes.

Frequently Asked Questions
Why do construction companies pay more for COIDA?
COIDA tariffs are risk-rated by industry. Construction has a higher injury rate than office work, so its tariff per R100 of payroll is higher. Subclasses within construction (roofing vs painting) are rated differently too.
Am I liable for my subcontractor’s injured workers?
Potentially yes. If a subcontractor is not registered or not assessed, COIDA can hold the principal contractor liable as if the workers were the principal’s own. Always verify subcontractors’ Letters of Good Standing.
Can I get on site without a Letter of Good Standing?
Almost never. Principal contractors, mines and corporates require a current letter before site access. Expired or missing letters stop work until fixed.
A dedicated COIDA service keeps contractors registered, filed and letter-ready.
