As somebody seems to think I know about this, I'll give it a go......
Kudos does not have an AOC and is apparently a brokerage company, based at Southend. As such, they would surely have
access to a large fleet, including some of the aircraft already mentioned. They should, however, check the legality/courtesy of using photos of other owners' aircraft without permission. But perhaps they have done this and have permission.
An owner of G-WUSH is learning to fly his aircraft with Southend-based instructors and it is hangared at Kudos on this basis. The aircraft is otherwise leased to AV8, which does operate the type on AOC: based, as are all its AOC operations, at Rochester.
AV8 has a TRTO approval at Southend, and leases facilities from Kudos on an ad-hoc basis for this: last used for two Huey courses a few months ago.
No financial or other links between the two,
AFAIK. There was, I understand, a tie-up planned between the two at one time, but interests appear to have diverged and the two companies are independent.
