A Fire Safety Regularisation Certificate is necessary when a building or works have been commenced or completed without having obtained a Fire Safety Certificate (FSC), where one is required. A Regularisation Certificate application process is similar to that of a Fire Safety Certification (FSC) application. However, it must include a Statutory Declaration form declaring that the submitted documents are true and accurate and correctly reflect the actual existing building.
Please note that the local authority fee for this regularisation process is higher that a standard fire safety certificate process, and the authority has up to 8 weeks to make a decision.
