[16] On 3 July 2018, she was consecrated a bishop by Justin Welby, the Archbishop of Canterbury, during a service at St Paul's Cathedral, London.

[20] In 2023, in reaction to the announcement that the Church of England was planning on introducing blessing for same-sex couples, she stated "I further support a change to the law that would allow for the marriage of same-sex couples in church, and regret that this proposal does not extend that legal change".

[22] In 2023, she was one of 44 Church of England bishops who signed an open letter supporting the use of the Prayers of Love and Faith (i.e. blessings for same-sex couples) and called for "Guidance being issued without delay that includes the removal of all restrictions on clergy entering same-sex civil marriages, and on bishops ordaining and licensing such clergy".

[26][27] In October 2016 Faull was instrumental in the sacking of all the York Minster bellringers with no notice on grounds of safeguarding,[28][29][30] and the subsequent suspension of a carillonneur.
