that would depend on the infrastucture cost to install such charging and to maintain it? This is kerbside slow charging presumably overnight. Note that spaces in these residental areas are typically not even marked spaces; the worst outcome might be losing more footpath space to charging infra for road users.

Non-fast chargers aren't very big. They can be installed in lampposts, or in lampost-diameter boxes sunk into the pavement (with the socket sticking out at the top)

The UK runs on 240V. A regular outlet would probably be fine.
