Whilst Parish Councils have no powers with regard to planning matters (the planning authority for Hathersage is the Peak District National Park) Hathersage Parish Council do see and comment to the planning authority on planning applications within the Parish. It is possible to see all current planning applications and planning decisions via the Peak Park planning application tool (this link will take you to applications in Hathersage parish only, you will be able to change the search criteria from that results page).

If you wish to submit a planning application then this page on the Peak Park website offers advice and information.
