Subcutaneous TYSABRI in NW England

Hello,
I will be moving to NW England in 2024 from France.
I am currently on tysabri (have been for about 18 months now) and was wondering which hospitals in the NW (especially in Manchester and Liverpool) offer subcutaneous tysabri.
If you are receiving this treatment in any of those hospitals, could you please tell me how it is going, how long you usually spend in hospital or any other info you might have about it as I cannot find much info online.
Currently, I get subcutaneous tysabri every 4 weeks at hospital and spend about an hour there (first come first serve basis so I get there super early to see the neurologist and as soon as I get the shots, I can go home - Is this how it works in the UK too?)
Everything is going very well for me so I am nervous about changing my habits and would really appreciate hearing about your experience.
Thank you!
