According to the regulations that were introduced in 2009, all gas installations must have a Certificate of Compliance according to the Pressure Equipment Regulations that have been established under the Occupation Health and Safety Act (No 85 of 1993).
According to the regulation, any home-owner who has liquefied gas installed in their home must have this certificate. Which is usually obtained during the installation.
The certificate of compliance is very important and must be provided by a certified gas installer.
A copy of the document has to be produced to your insurance company.
