@ T-Bone in particular:
At present, the churches (HTCD and StACC) are providing holiday support for kids in half-term holiday. Obviously Holiday Club will be a little different this year but there'll be plenty of activities for kids. Also, they're preparing for "Glitz'n'Glow" for younger children, as an alternative to dressing up as ghosts and ghoulies and going out trick or treating (the latter isn't really a very Brit thing or tradition, it's something that's crept in in recent years). So the little kids have a party with glow sticks and wearing their sparkly dresses (girls, presumably) or what-have-you, and they sing and dance and eat a few cakes or sweets.
Since the spring, our church partners with others in the locality, and with some supermarkets and the local Foodbank, to produce a Food Club. Impoverished people can join for a nominal amount and can then choose various fresh and tinned foods, which they can then buy at significantly reduced cost. I think toys etc are also available. (This is in addition to what is available from the local Foodbank, which has restricted access.)
A lot is being done to support those who are isolated for whatever reason: they're old and shielding; they're single-parent families with kids who have been sent home; families that are in self-isolation (so need meals or food sending in for them) (the city council also has schemes to help such people).
Right now, the council is proposing to refurbish two blocks of flats less than a mile from the church. They will do this by moving the tenants into another block of flats that's already been refurbished. This is going to be very disruptive for some of the tenants, who may not have very stable networks, or have other things in their lives that make them particularly vulnerable. So my church is reaching out to those who'll be moved (perhaps against their wishes) and saying, "We're here for you, how can we help/support you? What do you need?" Few if any of these go to any church and probably don't have much time for what (they think) we do. They may be surprised when they find out what a warm, friendly, welcoming and helpful bunch we are.
There are also plans afoot for another "StAction" day (St Andrews Community Church : StACC + Action = get it?), when my church hires a huge skip or two, and people from the local housing estate can bring their junk and toss in. Some of the estate inhabitants don't have cars or can't take their junk to the tip. Idea is to keep the estate clean and tidy, no junk in yards, abandoned mattresses in alleyways, etc, and thus raise the "wellbeing" feeling on the estate. Members of our church will also go to people's homes to collect junk if the occupants are unable to deliver. Originally, the skips were paid for entirely from our own church funds; however, the local social housing provider has realised what a good thing this is, and how much it helps the community, so now they give us some money towards the skip hire.
The hiring of the skips is often done in conjunction with a jumble sale in the church, and tea, coffee and cakes are also on offer to make a nice social occasion. That's not going to happen this year because of the requirement for social distancing.
