I woke up today at 11:45 pm by loud digging noise of road works. I understand that they have do work when the road is quiet. What annoys me is that we did not have any information before hand that such noise would be expected. Some prior information would be helpful, so we could be prepared. Who can I contact?
You can contact your environmental health and highways departments. Emergency works will normally be unannounced but it would have been polite to have notified immediate neighbours of any planned overnight works (although there may be no legal duty to do this unless it forms part of the permission granted in the form of a condition). You can also complain to the authority who has authorised the works and the entity who are carrying them out. Highways departments often give consent to road works to utility companies. You could find out whether the company concerned have any prerequisite permissions (if required).
