What is a Certificate of Compliance (CoC)? The Complete South African Guide

Updated for 2026 · 8-minute read · Written by the team at Western Cape CoC Certificate

Western Cape CoC Certificate has over 25 years of experience issuing compliance certificates across Cape Town and the Western Cape and has assisted more than 10,000 property buyers and sellers understand their CoC obligations. In this guide we explain exactly what a Certificate of Compliance is, which ones are legally required in South Africa, what each one tests, and how the process works from inspection to certificate issue.

The Simple Definition

A Certificate of Compliance (CoC) is a legal document issued by a government-registered inspector confirming that a specific installation in a building — such as the electrical wiring, gas pipework, or electric fence — complied with the applicable South African National Standard (SANS) at the time of inspection.

The word compliance is key: the certificate does not guarantee the installation will remain compliant forever. It is a snapshot — a declaration by a qualified inspector, made on a specific date, that the installation met minimum safety standards on that day.

Why Does South African Law Require CoCs?

Three pieces of legislation drive South Africa’s compliance certificate requirements:

• Electricity Act No. 41 of 1987 (and the Electrical Installation Regulations GNR1593 of 2009) — makes it a criminal offence to sell a property without a valid Electrical CoC. The DoEL (Department of Employment and Labour) oversees enforcement.
• Occupational Health and Safety Act (OHS Act) — Electric Fence System Regulations — requires an Electric Fence CoC whenever a property with an electric fence changes hands.
• Gas Act No. 48 of 2001 (and the Pressure Equipment Regulations) — requires a Gas CoC for any property sale where a gas installation is present.

In addition, the City of Cape Town Water Services By-law No. 14 of 2010 requires a Plumbing CoC for all property sales within the City of Cape Town’s municipal boundaries — making it a Cape Town-specific requirement not found in most other South African cities.

The 5 Types of Compliance Certificates in South Africa

What Happens During a CoC Inspection?

The inspection process varies slightly by certificate type, but the general steps are:

1. Booking: You contact a registered inspector and arrange a time. For all 5 CoC types simultaneously, expect a 2–4 hour on-site window.
2. On-site testing: The inspector uses calibrated test instruments (for electrical: Megger MFT1735, Fluke 1587FC; for gas: calibrated manometer and electronic leak detector; for electric fence: calibrated voltage meter) to test all components of the installation against the applicable SANS standard.
3. Pass or fail assessment: The inspector determines whether the installation is compliant. In Cape Town, approximately 78% of homes require at least some remediation before passing the Electrical CoC.
4. Defect report (if failed): A detailed written report is issued listing every non-compliance with its SANS clause reference and a remediation cost estimate. This typically takes less than 24 hours.
5. Remediation (if required): A registered contractor repairs the defects. Timeline: 1 day (minor) to 10+ days (major board replacement).
6. Re-inspection and certificate issue: The inspector returns, confirms all defects are resolved, and issues the signed CoC. Certificate is delivered digitally within 24 hours of passing.

What a CoC Does NOT Cover

• Portable appliances (kettles, fridges, washing machines, TVs)
• Structural integrity of the building
• Roof condition, dampness, or waterproofing
• Age or condition of equipment (only that it was compliant at inspection)
• Work done after the certificate was issued
• Common property in sectional title schemes (that is the body corporate’s responsibility)
