Planning for Snowdonia


We are currently experiencing a high number of enquiries which may result in a delay responding to you, we can only apologise for this.

We are working hard to ensure the Planning Service is  maintained during these unprecedented times, but as the majority of staff are still working from home some delay is inevitable.

Should you be seeking advice on whether a proposed development requires planning permission or advice on the acceptability of a proposal at pre-application stage you will be required to complete a pre-application advice form which can be found along with guidance notes by clicking here.  Unfortunately enquiries of this type cannot be answered over the phone and will not be processed without the completion of the pre-application form, supporting information such as sketch plans and photographs and if applicable, the payment of the appropriate fee.

Please note from 24th August 2020 planning application fees in Wales will increase by 20%. For more information click here.

The Snowdonia National Park Authority is the Local Planning Authority for the National Park area. It has a statutory obligation to prepare a Development Plan and determine planning applications under the provisions of the Town and Country Planning Act 2004.

In carrying out its statutory planning responsibilities, the National Park Authority (NPA) must also have regard to the statutory responsibilities and management role of National Park Authorities as set out in the Environment Act 1995.

These purposes are to:

  • Conserve and enhance the natural beauty, wildlife and cultural heritage of the Park.
  • Promote opportunities for the understanding and enjoyment of the special qualities of the Park, by the public.

The National Park also has a duty to:

  • Seek to foster the social and economic well being of the local communities within the Park area.

The adopted development plan for the Snowdonia National Park is the Eryri Local Development Plan (end date 2031) which was adopted by Snowdonia National Park Authority on the 6th of February, 2019. The plan seeks to express Park purposes and duties in terms of land use, planning and development policies.
