Boiler courses

[Irish]

Evening all, I was wondering how useful the courses hosted by Worcester Bosch , valiant , baxi are worth taking in terms of increasing knowledge and breakdown repairs or is there a course in the London area that any of ye would recommend?? Thanks

I have done a few baxi courses, and the Vaillant ecotec course. They're good for getting the basics, and to get an understanding of how things work
