Would highly recommend an IMI Approved Centre, they set the NOS (National Occupational Standards) for the Industry, you can search here:
https://tide.theimi.org.uk/search/centre
Not to be confused with membership which is a crock of shit.
They also offer EV quals, L3 takes only 5 days, not all the centre's offer the full range, you will have to contact the centre's or IMI Directly.
