I don't know about the Netherlands, but in Britain the Federation of Independent Evangelical Churches and the Assemblies of God (Pentecostalist) have gradually been permeated by dispensationalist eschatology. Then there are still the Plymouth Brethren. And other sectarian groups either loosely based on neighbourhood and house prayer/Bible study groups, or on a more "cult" organisation. At least one of these last that I know of has very close contacts with similar Dutch groups. (That sect, btw, grew in the 1960s out of a Baptist Church).
