Keeping Churches Open I think that is what will happen in many places where there is just one building and a community, provided the building is not in bad condition already. Churches cost a lot to heat, maintain and insure. There could be a lot of pressure on groups of churches where they just aren't all needed.
The level of listing is actually quite an important consideration in this. Any church that is Grade I listed will end up in the care of the Churches Conservation Trust, so bells in such churches are likely to be safe. CCT does care about bells, although they do not necessarily have funds to prioritise their upkeep or improvement. A church that is Grade II* is quite difficult for the Church Commissioners and Dioceses to sell because they present planning challenges so they are likely to hang around longer. The riskiest ones are those that are just Grade II because they are more developable and hence more saleable.
I was talking to Peter Aiers at the CCT a few months back and looking at his map of where their churches are. They have hardly any in the South West, and he said that is because there is a far lower average level of listing in the South West and relatively few Grade Is. Having spent a week in Devon last week it did sem that churches and towers are less ornate - perhaps it is something about building to survive coastal weather conditions, something about the available stone, or some other quirk of history.
