New UK Study Finds Evangelicals Are Younger and More Diverse

A major 2026 survey of more than 8,400 UK adults examines evangelical identity, beliefs, age and ethnicity, finding a significant evangelical presence among younger and ethnically diverse Christians.

A new study of evangelical Christianity in the United Kingdom is providing a detailed look at who identifies with evangelical Christianity, what they believe, and how evangelical communities are represented across different age and ethnic groups.

The research was commissioned by the Evangelical Alliance UK and conducted by Whitestone Insight. Researchers surveyed 8,407 UK adults between February 25 and March 8, 2026. Among those surveyed, 3,804 respondents who identified as Christian were asked additional questions about their beliefs and identity.

The resulting report, Understanding UK Evangelicals, examines the size, beliefs, demographics and identity of evangelical Christianity across the United Kingdom. The Evangelical Alliance describes it as one of the largest studies of evangelical identity and belief conducted in the country.

Quick Summary

• Who: Evangelical Alliance UK and Whitestone Insight.
• Where: United Kingdom.
• When: Survey fieldwork took place from February 25 to March 8, 2026.
• Sample: 8,407 UK adults, including 3,804 respondents who identified as Christian.
• Key finding: Evangelical identity and belief are particularly prominent among younger adults and include substantial representation from ethnic-minority communities.
• Important limitation: The survey should not be treated as a direct year-to-year measurement of evangelical growth because previous studies used different methodologies.

What the Study Found

The report estimates that approximately 12.3 million people in the UK either hold evangelical beliefs, identify as evangelical, or both. The researchers distinguish between several groups according to evangelical beliefs, self-identification and Protestant church tradition.

The study estimates that about 11.4% of UK adults identify as evangelical, while approximately 14.1% hold evangelical beliefs. It also identifies approximately 5.5 million people as "broad evangelicals" and about 2.6 million as "classic evangelicals" under the study's definitions.

Among people the researchers classify as practising Christians—defined in the report as people who attend church at least monthly and who also pray and read the Bible independently at least weekly—approximately 64% are classified as broad evangelicals.

A Younger Evangelical Population

One of the study's notable findings concerns age.

Adults under 35 were the age group most likely to identify as evangelical and hold evangelical beliefs. Among the study's "classic evangelicals," approximately 43% were under 35, including 19.4% between 18 and 24 and 24.1% between 25 and 34.

Among "broad evangelicals," approximately 41% were under 35.

These findings provide a more detailed picture than simply measuring whether people describe themselves as Christian. The study examines both evangelical identity and beliefs using specific criteria established by the researchers.

Ethnic Diversity Is Also Significant

The research also found substantial ethnic diversity within UK evangelicalism.

Approximately 30% of evangelicals were from ethnic-minority backgrounds, compared with 17% of the wider UK adult population in the study's comparison. Among classic evangelicals, approximately 27.9% were Black respondents.

The findings indicate that British evangelical Christianity includes people from a range of ethnic and cultural backgrounds rather than representing a single demographic group.

What the Numbers Do—and Do Not—Show

The Evangelical Alliance has presented the findings as evidence that evangelical Christianity remains a significant part of British church life and has a substantial presence among younger and ethnically diverse people.

However, there is an important methodological qualification.

The 2026 survey cannot simply be compared with older estimates as though the surveys measured exactly the same population in exactly the same way. The Evangelical Alliance notes that earlier research, including Tearfund's 2007 study, used a different methodology.

The 2026 research therefore provides a new picture of evangelical identity and belief in Britain, but comparisons with previous studies should be made carefully. The survey used an online sample of 8,407 UK adults and reported a margin of error of approximately 1.6 percentage points.

Why This Matters for the Church

The study provides useful information for churches thinking about discipleship, evangelism and ministry among younger generations.

The presence of younger adults within evangelical Christianity challenges the assumption that serious Christian commitment is necessarily concentrated among older generations. At the same time, the findings should not be interpreted as evidence that Christianity as a whole has stopped declining in Britain.

The broader British religious landscape remains complicated. Christian identification has declined in recent decades, while this 2026 study is specifically examining evangelical identity and belief rather than the entire Christian population.

What the research does provide is a clearer picture of a particular part of British Christianity that includes significant numbers of younger and ethnically diverse people.

Christian Context

Demographic research can help churches understand the communities they serve, but the faithfulness of the church cannot ultimately be measured by population numbers alone.

Scripture places the emphasis on faithfulness to Christ, the proclamation of the gospel and the teaching of God's Word. Jesus commanded His disciples to make disciples of all nations, while Paul instructed Timothy to entrust the truth to faithful people who would be able to teach others also.

"And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also."

2 Timothy 2:2, KJV

From that perspective, the presence of younger Christians is important not merely because of demographics, but because the church is called to faithfully pass the gospel from one generation to another.

A younger church also needs biblical depth. Numerical or demographic strength by itself does not establish faithfulness. Christian maturity involves growing in the knowledge of Christ, obedience to Scripture, love for the church and readiness to serve others.

What We Still Do Not Know

The survey does not establish that every category of evangelical Christianity is growing at the same rate. It also does not demonstrate that all UK churches are experiencing younger congregations or that evangelical churches are uniformly healthy.

In addition, the survey measures beliefs and identity through specific questions and definitions. Different definitions of "evangelical" can produce different estimates, so the report's categories should be understood within its methodology.

The research also represents the UK population and should not automatically be applied to evangelical Christianity in the United States, the Philippines or other countries.

What Happens Next?

The findings are likely to contribute to continuing discussion about the future of evangelical Christianity in Britain, particularly concerning younger adults, ethnic diversity, discipleship and church participation.

For churches, the practical question is not simply how many people identify as evangelical, but how faithfully churches are making disciples, teaching Scripture and proclaiming Christ across generations and cultures.
