Bless Every Home is a website dedicated to encouraging people to commit to praying for their neighbour. While this service in particular is focussed on the US, and it’s unlikely that privacy rules would allow for an identical service in the UK, it is still something to consider.
For example, it might be possible to allow people in your community to sign up for prayer, and then a limited amount of information shared with parishioners who can then pray for the individuals.
As this article in the Tablet reports, Google Trends data showed a very large increase in searches for ‘prayer’ following the COVID-19 global pandemic, so we can be certain that people are looking for prayer.
