The NVQ is (or was) free through training providers such as Geason, presumably government funded but as mentioned before you already have to be rendering before you can do this, we are not offering NVQ's though, we are teaching them how to render and to apply EWI systems.
The manufacturers and such will be offering Green Deal Installer accreditation soon but again you can not get this unless you can already render and use EWI systems (you can see the repetition) We are here to help people learn how to render and appreciate that people will then choose there path after that whether it be working for themselves, working for a bigger contractor, getting green deal accreditation ....
How long is a piece of string when it comes to when they can go out on there tod, if they are already plastering it is an easy transition once you know the materials, tools and processes.
