I've been in the plumbing game about 5 years, earning my living with plumbing repairs & maintenance (rad installs, taps, inlet valves... the usual). I've got a NVQ Level 2 in Plumbing Craft that my dad put me through when I worked as his apprentice as a bathroom fitter. What do I need to study to get ACS? It's pretty confusing - do I need to spend time alongside another engineer and take NVW Level 3 Gas Installations? Any help, advice or personal experience on what path I should take is greatly appreciately Cheers!
