According to "Muslim Prisoners' Experiences" report by Chief Inspector of Prisons, Dame Anne Owers, conversion to Islam in prisons in the United Kingdom is attributed to converts seeking "support and protection in a group with a powerful identity" and "perceptions of material advantages of identifying as Muslim" in prison, including perks or "material benefits" available only to Muslims "such as more time out of their cell and better food during Ramadan if they become Muslim".[11]

In 2015, it was reported that there was "a surge in Muslim inmates in recent years, with one in five of those serving sentences in Britain's maximum security jails now said to be following Islam, according to union officials. The Prison Officers' Association has put that down to thousands of lags becoming so-called "convenience Muslims" – converting to the religion to deliberately play the system. [ ...] It added they were also being made even more vulnerable to radicalisation."[12]
