From their "About us" page:
"The Substance Misuse Skills Consortium is an independent, sector-led initiative to harness the ideas, energy and talent within the substance misuse treatment field, to maximise the ability of the workforce, and to help more drug and alcohol misusers recover"
The matrices are on the website, but you'll also find some great stuff in the Skills Hub including resources sorted by substance type and by treatment phase.
