There is no single "right" way into plumbing, which is exactly why it confuses people. Here are the routes that genuinely work, what each involves, and where the alphabet soup of qualifications (Level 2, Level 3, NVQ, ACS) fits in.
Apprenticeship vs college vs plumber's mate — the genuine ways in, and where the qualifications fit.
Apprenticeship — the strongest route for most
An apprenticeship lets you earn while you learn: you work for an employer and study towards your Level 2 then Level 3 alongside the job, building real on-site experience the whole way. It is competitive to get onto, but it is the route the trade respects most — and you are paid throughout.
College, then get on site
You can study a Level 2 Diploma at college first. It gives you the underpinning knowledge, but on its own it is not enough — the competence side (the NVQ) needs you to evidence real work. So the plan is: get the Level 2 theory, then get onto site (often as a mate or labourer) to build the experience and finish the qualification.
Plumber's mate — the foot in the door
Working as a plumber's mate or labourer is a legitimate way in. The pay is modest and the work is hands-on, but you learn fast, make contacts, and put yourself in exactly the position to pick up the on-site experience your qualification needs. Many qualified engineers started here.
Where gas and ACS come in
Gas is a separate step, and it comes later — not first. To work on gas you need current ACS certificates and Gas Safe registration, which build on plumbing/heating experience. Trying to start your whole career with a quick gas course is the wrong order; get grounded in the trade first.
What you do not need
You do not need a five-figure fast-track course to get started — and a qualification without on-site experience will not get you hired on its own. We covered why in a separate honest guide; the short version is that experience, not a certificate alone, is what makes you employable.
