We often mention simply-docs, the commercial site that offers cost-effective policy templates for data protection and many other areas.
They also have a comprehensive range of charity governance and administration policy and procedure templates. These are in the Corporate section, so any existing subscription might need to be extended but you view the list without cost at https://simply-docs.co.uk/Corporate-Documents/Charities.
This can really help you fast track your policy creation/review process.
