England
England's writing-workshop scene benefits from a dense concentration of universities, several of which, including those in London, Norwich, and Manchester, run highly regarded creative writing programs alongside public-facing workshops. Norwich's status as a UNESCO City of Literature has helped make it a particular destination for both students and working writers.
Community-run workshops are common in smaller towns and cities as well, often tied to local libraries, arts centers, and writers' circles, giving aspiring authors options well beyond the major university towns.

University-affiliated workshops in England can be more structured and application-based than community groups, so check the commitment level and any prerequisites before applying.
