Legislation covering the control of noise is to be found in the Environmental Protection Act 1990 and the Control of Pollution Act 1974. In the usual way, communities may contact their local authority and register concerns over excessive noise, vibration, odour, light or dust. The local authority has a duty to investigate complaints and is required to take enforcement action under the relevant legislation. Further information on how local authorities deal with such complaints can be found at Noise nuisances: how councils deal with complaints. Before complaining to the local authority, communities and constructors should work together to find solutions which are suitable for both sides. All sites should have a designated contact phone number, staffed during hours of site operation, for local residents or businesses to contact, and this should be displayed prominently
