How would that work? The UK can presumably ban Mullvad from operating in the UK, but I don't see how it can prevent outbound connections to Mullvad servers elsewhere, short of implementing a nation-wide firewall like China or Iran. And even in those places the firewall is pourous and routinely circumvented.

mullvad client relies on known servers, you could ban their access at the IP level from UK ISP. nothing complicated really
