Planning Permission York: New BNG Rules

When embarking on a new development project, specific procedures must be followed in order to facilitate the project’s progression. Obtaining planning permission can be a complex but necessary process for those wishing to start a new development project.

New rules which come into force from 12th February 2024 mean that biodiversity net gain will become a mandatory component for all development projects.

Planning Permission, York: The process

Once you are ready to proceed, you should submit a full planning application to the local planning authority. Applications can be submitted online through the Planning Portal or directly to the local planning authorities.

The local planning authority will validate the application, checking if all necessary documents and information are provided. Incomplete applications may be returned.

Some applications may require a public consultation period, where neighbours and other stakeholders can express their views on the proposed development. Anyone can comment on planning applications or check the progress of an application on the York planning website.

A planning officer will make a decision notice based on planning policies, relevant considerations, and public input. The decision can be approval, approval with conditions, or refusal.

More details of planning requirements can be found on the public access City of York Council planning website.
