Church adapting to survive? I don’t know whether anyone can really provide evidence that changes they have made enable them to be financially viable for the future but I do remember an article about a church I think in Cornwall which had significantly increased ‘visitors’ and donations by bringing in community activities ranging from ringing sessions to playgroups. I think it was part of the Save the Parish information but it might have been a Ringing World article.
There’s a discussion thread called The Road to Wigan’s Tears which goes into this topic a little bit and Simon Linford has provided some good information on categories of churches and what level of attendance / funding a church needs to achieve to survive.
I guess the St Clements Cambridge model uses ringing as a way to keep a church building open every day but this works for Cambridge as a city with lots of visitors and wouldn’t work in a rural village so it will depend on the exact location.
I remember being surprised in the article about the church in (I think) Cornwall that very few regular visitors were needed to justify keeping the church open and be considered a success.
My home tower church is considered a success because the church is hired out for recordings and filming and this brings in income despite a relatively small congregation but this works because it’s in London and with good acoustics so wouldn’t work everywhere.
I think I would start by looking at the equivalent community hall facilities in the local area and what happens there, if there is already a scout hut or Methodist hall or similar being used for yoga classes, music for toddlers, etc then the church has less chance of finding other users but if there’s a need for spaces which is not fulfilled then churches work well as food banks, libraries, cafes, music venues…
