FixMyStreet
/FixMyStreet is a standalone website and also a popular addition to community and local websites, which can be used to show reported problems, comments and updates in an area.
You can use the website to search for your local postcode and enter issues onto the map, such as streetlights being out of action or potholes. The issue is then automatically highlighted to the relevant authority.
You can also use the map feature to see what other issues have already been highlighted in your area.
