Some parts of the evangelical world in England are growing quite quickly. Between 2005 and 2010 the number of mainstream evangelical churchgoers grew by over 100,000 new people per annum to reach 650,000, half of all the 1.3 million evangelicals in 2010.
That number has continued to grow between 2010 and 2020, although at only half the rate – 50,000 per year. However, the overall evangelical total in 2020, 1,280,000, will probably be 16,000 fewer than the 2010 total as broad and charismatic evangelicals have lost numbers. In short, in 2020, Pentecostals will be one-third, 34%, of all evangelicals.
At the turn of the century the largest Pentecostal churches were the Assemblies of God and Elim, but their numbers were soon to be challenged by others like the Redeemed Christian Church of God (RCCG) and Kingsway International Christian Centre (KICC). RCCG has always had multiple congregations, while KICC had one enormous church in Hackney (10,000+ strong) which unfortunately had to be moved to make way for the London Olympic Arena. This was eventually rebuilt in Chatham, Kent.
