Westminster City Council is installing electric vehicle charging points on city streets and in off-street locations to improve air quality and support electric vehicle use. They have installed 12 on-street charging points and 40 off-street points so far, which have over 200 and 230 members respectively. Key considerations for installing on-street points include compliance with design guidelines, avoiding street clutter, durability, accessibility, and compatibility with electric vehicles. Challenges include managing parking revenue, traffic orders, installation costs, and maintaining the scheme. The council aims to expand the program and work with other boroughs.
