If all components used with a DIY charging charging stations meet all required standards. Assembled by a competent person I do not see a problem in general.
I agree that ZCW/Mainpine need to issue a leaflet with the unit and ensure it is highlighted when it is being sold that a qualified electrician need to insure that the final installation is safe.
If you are making a portable DIY charging station again it need to be checked to see if it is safe and that it will require regular 'PAT' testing.
I also know that you can purchase EV control modules similar to the Mainpine one from 3 well known companies including at least one within UK EVSE.
There is also at least one within UK EVSE using re-branded Mainpine hardware.
