Frequently asked questions

What counts as 'major development' in planning terms?
Generally 10+ residential units, sites of 0.5 hectares or more for housing, or commercial buildings over 1,000m². Major applications have a 13-week statutory decision target (or 16 weeks where an Environmental Impact Assessment is required).
How do I object to a commercial development near me?
Submit comments via the council's planning portal during the consultation period (usually 21 days). Material considerations include traffic, noise, scale, design and impact on amenity. Loss of view, devaluation of nearby property, and personal preference are not material considerations.
Can I get email alerts for commercial & major works planning applications anywhere in Wales?
Yes. Click the "Set up alerts" button on this page and you'll get a daily (or weekly) email listing every new commercial & major works application submitted anywhere in Wales. No need to pick a postcode or draw a map - pick the category once, choose your frequency, and we'll do the rest.
