Between 2010 and 2019, 209 consecrated churches were formally closed, which amounted to just over 1%. Since the 1990s the rate of closure has remained steady at 20-25 per year out of a total of around 16,000 church buildings. It is important to note that new churches are also being built and that some congregations meet in other kinds of buildings.

Churches are first and foremost places of worship. The 2017 Taylor Review into sustainability of English Churches and Cathedrals ( https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/669667/Taylor_Review_Final.pdf ) found that the Government could also enable the church to serve local communities better by reviewing planning law around listed buildings, to enable Local Authorities to think more imaginatively about diversification and wider use. For over a decade the Church of England’s own ‘open and sustainable churches’ programme, has encouraged churches to consider partnering with a wide variety of community resources (e.g. post offices, village shops, children’s play areas, credit unions, foodbanks, co-working spaces) in sharing space: Sharing your building and finding partners | The Church of England
