Just Gas - Not compliant?

Very disappointing...<br> <br> Johan installed our gas system & new gas stove at the end of May 2015.<br> <br> They did a great job - the piping laid was impeccably neat.<br> Very disappointing then, that since making payment we have not received any response to our numerous correspondence requesting our Certificate of Compliance.<br> This is imperative , as it guarantees the safety of the instillation, and the property cannot be insured or sold until we have this document.<br> We have sent no less than 7 emails since, with not even a response, in nearly 1.5 months.<br> <br> Be wary - this certificate is a legal requirement of gas installation, and a consumer is putting themselves, family & home at extreme risk with a company which may not be complaint, as they advertise.
