Hi.
CFS Aeroproducts Ltd do trainig courses. In UK, however it seems to be stooped due to covid until 2021.
Here is the response they sent me.
We do and I have attached our course brochure above for your information, however our courses are currently postponed until the New year 2021 so I will be back in touch with you then once I have the dates confirmed.
Kind regards,
