There are three Gateway Stages:
Gateway 1
The planning stage. Applicants will need to demonstrate that fire safety matters have been considered.
Gateway 1 came into force on 1 August 2021 through the introduction of the Town and Country Planning (Development Management Procedure and Section 62A Applications) (England) (Amendment) Order 2021. This requires fire safety matters to be incorporated into the planning stage for higher-risk buildings. The HSE will be a statutory consultee, and submission of Fire Statements will be required when seeking planning approval.
Gateway 2
Construction cannot begin unless the Regulator has approved the application.
Before construction can commence, clients (with the help of the duty holders) must submit a building control approval application to the Regulator. Detailed information needs to be provided at this stage, and the Regulator has a proposed 12- week period to approve or reject these building control applications or to approve subject to the fulfilment of certain requirements. It is important to note that the Regulator will monitor any changes to approved building work through a system of change control applications.
Gateway 3
Upon construction, the occupation will not be allowed until the Regulator has completed final inspections and issued a Completion Certificate.
Gateway 3 is intended to confirm that the building is safe for occupation and requires the issue of a Completion Certificate from the Regulator. Clients will be required to submit a Completion Certificate application and provide updated plans showing the size and position of the as-built higher-risk building, key building information, a list of all mandatory occurrence reporting, together with signed declarations from the principal contractor and the principal designer that the works and building comply with the Building Regulations.
