This notice appeared yesterday on the Central Council of Church Bell Ringers’ website:
What the Church is expecting is tolling of a single bell during the hour before the funeral, which starts with a minute’s silence at 3pm on Saturday. You don’t need to toll for the full hour, just during the hour, e.g. up to 3pm. Half muffled preferred, but a single bell tolling slowly whether half muffled, fully muffled, or even unmuffled, will have the desired effect.
The News tab of the ODG website will be updated with any other developments.
