The Government guidance can be found here:

Bishop Marcus has asked all priests to contact their parishioners as soon as possible and encourage them to immediately email or contact their MP to request that the guidance is amended to allow places of worship to remain open for acts of worship and religious services.

Here is a copy of a letter which Bishop Marcus has sent to the Prime Minister and to MPs in the Diocese of Leeds which you could use as an example.
