BUILDING CONTRACTORS / REAL ESTATE DEVELOPERS
‘Time is money’ – Poor electrical workmanship can lead to delays and financial losses.
We collaborate with builders and contractors to ensure timely and accurate completion of all electrical projects.
WHAT IS A CERTIFICATE OF COMPLIANCE?
According to the Occupational Health and Safety Act, all consumers of electrical installations must have a valid Certificate of Compliance. This certificate confirms that the property’s electrical connections are legal, safe, and in working order. At ESG Services, we have over 28 years of experience in issuing these certificates, ensuring your property meets all regulatory standards.
WHEN DO I NEED A CERTIFICATE OF COMPLIANCE?
Any premises that have undergone electrical installations since 1992 require a Certificate of Compliance. This certificate is essential for legal and safety reasons, and beneficial for unexpected visits from the Department of Labour. While the onus for obtaining the certificate rests with the owner, only a qualified electrician can issue it.
