The ComRes survey, commissioned by Christian youth organisation, HOPE revolution partnership, claimed one in six young people are practising Christians and around 13 per cent of them decided to become a Christian after visiting a church.
The study also found that the influence of a church building was stronger than going to a wedding, speaking to other Christians about their faith or going youth groups.
The Church of England's national youth evangelism officer, Jimmy Dale, said he was stunned by the results.
He told The Sunday Telegraph: "What is really exciting for us is that there is this warmth and openness that we are seeing among young people, they are really open to faith".
Seventeen per cent of those of surveyed said that going to a religious school contributed to them choosing Christianity. On the other hand, 14 per cent said a spiritual experience led them to join the faith.
Dale added that the results show the impact a church building can have and that traditional methods of sharing Christianity still work.
He said: "Things which we would class as old-hat methods are some of the more effective ways.
"It's a wake- up call for the church. We've got lots of young people who are coming into churches, that's a really integral part of becoming a Christian. "
