I'm looking for recommendations of a good level weekend ( Saturday, Sunday) gas engineer training. Does anyone know a good course for beginners in London?

Same here, This would be useful actually for me too. I'm only really free on the weekends and I'm thniknig about taking a plumbing course at college but I'd like some prior knowledge before I start... Would a weekend course suit me at all? Steve
