Technical Requirements

General advice on 'permitted development' and whether your project may require planning permission can be found on the government's Planning Portal. Local authorities may have local planning application requirements specific to their area in addition to national requirements. Also, there are likely to be different rules in Conservation Areas, National Parks and when working with or near Listed Buildings; we can advise you on this.
