Every certificate in the group is held by a named legal entity, and this page says which one. Third-party accreditations are held by Gemini AMPM Ltd in its own name. AMPM Building Services Ltd and AMPM Group Ltd hold none yet, and do not borrow them. Where a renewal is still being confirmed, the row says so rather than claiming it.
