IMO, it won't be long before the UK Space Agency / ESA provide SAS with a grant.
We do know through Meidad's FB posts that the ESA are working with companies such as SAS on new 5G initiatives, so SAS have certainly forged a close relationship with the ESA.
Looking back at some news feeds, I noticed that the UK Space Agency (via the ESA) provided OneWeb with a 23M grant.https://www.spaceitbridge.com/oneweb-picks-up-23-5m-in-uk-funding.htm
