For Christianity, according to the office of national statistics though, in 2019 In 2019, an estimated 51.0% of the population reported their religion as Christian.

That is the headline findings of the 2018 British Social Attitudes Survey, the results of which are published today. The survey, which offers a detailed look at the non-religious and religious beliefs of the British adult population for the first time since 2008, concludes that there is ‘compelling evidence that the process of secularisation continues unabated.’
The survey finds that 52% of people belong to no religion, 12% are Anglicans, 7% are Catholics, 19% are some other type of Christian, and 9% belong to a non-Christian religion. The rise of the non-religious is largely attributed to generational change – and with just 1% of those aged 18-24 saying they belong to the Church of England, the trend looks set to continue
The census in 2011 asked:
"What is your religion?"
A different question to:
The British Social Attitudes Survey uses a two-part question which asks ‘Do you regard yourself as belonging to any particular religion?’ and ‘If yes, which?’ This approach gives a reliable indication of the actual identities of Britons, unlike the Census.
When asked the census question ‘What is your religion?’, 61% of people in England and Wales ticked a religious box (53.48% Christian and 7.22% other) while 39% ticked ‘No religion’.
But when asked ‘Are you religious?’ only 29% of the same people said ‘Yes’ while 65% said ‘No’, meaning over half of those whom the census would count as having a religion said they were not religious. Even more revealingly, less than half (48%) of those who ticked ‘Christian’ said they believed that Jesus Christ was a real person who died and came back to life and was the son of God. Asked when they had last attended a place of worship for religious reasons, most people in England and Wales (63%) said they had not attended in the past year, 43% of people last attended over a year ago and 20% of people had never attended. Only 9% of people said they had attended a place of worship within the last week.
