WSelectrical....if you join Napit you just need to have your 17th, they will send assessor around and check your work, ability to test, if all is fine then you will be granted membership on the condition that you complete a trade test with 6months, giving you a blueflame certification, and also one of the conditions is that you gain the 2391 testing & inspection within 18months. Seems better than 2/3 years of 2330 if you already have experience.Also Part P is a building reg and not a qualificationPart P is a scheme you join so don't let any private training company charger you ÂŁ2000 and tell you your getting a Part P qual as there is no such thing.
