Main Religion in the UK: Christianity (Anglican), But Rapidly Diversifying

Official Position vs. Lived Reality

Constitutional Status

  • Church of England (Anglican) = established church in England. Monarch = Supreme Governor. Bishops sit in House of Lords (26 Lords Spiritual).
  • Church of Scotland (Presbyterian) = national church in Scotland (not "established" same way; sovereign in spiritual matters).
  • Wales & Northern Ireland: No established church (disestablished 1920, 1871).

Census Data (2021/2022)

Key Trends

  • "No religion" is now the largest single group in England/Wales and Scotland.
  • Christian identification dropped 13+ points since 2011 (59.3% → 46.2%).
  • Non-Christian religions growing (immigration, higher fertility, conversion).
  • Attendance <<< identification: <10% of Christians attend weekly; cultural affiliation dominates.

Practical Implications

  • State ceremonies (coronation, Remembrance, parliament opening) = Anglican.
  • Schools: ~1/3 state-funded schools have religious character (mostly CofE, Catholic).
  • Law: Blasphemy abolished (2008). Equality Act 2010 protects religion/belief.
  • Marriage: Civil, Anglican, other registered venues. Same-sex legal UK-wide (2014/2020).

Bottom Line

Christianity (Anglican) is the historic, constitutional "main" religion—but "No Religion" is now the plurality in Great Britain. The UK is a secular state with an established church in one jurisdiction—a unique, evolving settlement.
