We have a community support group on our road (and a few side roads) that was formed 2 weeks ago. Posters on gate posts and in windows giving contact numbers for help. Today we delivered pairs of red and green cards (printed A5) for our section of the road (every section is covered by a volunteer) for people to put in their windows - green means all OK; red means help wanted (with a short tick box list on it to say whether it is shopping, medicines, telephone contact or whatever). My partner has volunteered to check our addresses every day and we will follow up on any red cards.
