Update on Gwynedd’s Article 4 Direction – October 2025

A recent High Court ruling has found Cyngor Gwynedd’s implementation of the Article 4 Direction to be legally flawed. The judgment concluded that Cabinet members were misled regarding the scope and legal effect of the Direction, particularly in relation to what constitutes a “material change of use” between residential categories (C3, C5, C6).

However, the Article 4 Direction remains in force.Cyngor Gwynedd is actively pursuing an appeal, and until a formal Court Order is issued, property owners must continue to seek planning permission before converting a main residence into a second home or short-term holiday let.

Key implications for property owners:

Planning permission is still required for changes of use between C3 (main residence), C5 (second home), and C6 (holiday let).

The legal basis for automatic planning requirements has been challenged, but not yet overturned.

The outcome of the appeal may result in policy revision or withdrawal—updates will follow as the situation evolves.
