The House of Bishops revised their guidance on access to churches on the 5th May 2020.
The new guidance can be read here: https://www.churchofengland.org/more/media-centre/news/house-bishops-backs-phased-approach-revising-access-church-buildings

Government guidance states that ‘a minister of religion or worship leader may leave their home to travel to their place of worship’. In most cases, they will do so in order to pray or to stream a service of worship. If clergy wish to mark VE Day by ringing a church bell or flying a flag from their church buildings, that is within government guidance. This advice does not extend to bell-ringers, sextons or other church officers or volunteers.

The parish church would usually be central to local commemorations of events such as Victory in Europe Day, but for this anniversary they will be honouring the sacrifice of all those who were involved in World War Two in a new way. Archbishops, Bishops and clergy will be participating in local and national virtual services to mark VE Day. The Church of England has released national resources for worship and prayer which can be used by local communities: https://www.churchofengland.org/prayer-and-worship/worship-texts-and-resources/worship-resources-ve-day-2020

Additional resources have been released by Westminster Abbey to help churches shape their services over the anniversary weekend which can be found here: Service of Thanksgiving to mark the 70th Anniversary of VE Day
