NCC Property Services have created a page within the Schools Portal which provides advice and instructions regarding the management and operation of property to ensure that during this crisis period, properties, whether in temporary reduced usage or closed, are managed in a manner that keeps them safe and compliant for building users, secure and will enable them to be brought back into full use at the appropriate time in a safe manner.
Please review the information provided here. This information will help you to understand what you need to consider for your site in terms of maintenance, compliance and security whether you are open/closed or partially open.
