hi @David260
SKY Q (& SKY +/HD) do need to have a Satellite dish that has clear sight of the Satellites.
If there is tree coverage or other obtructions which cannot be removed & no alternative position suitable then, probably, your only option to continue with SKY is streaming as advised by the engineer.
You will need to call SKY to discuss & arrange
BTW we are, primarily, just other customers here and help give advice
edit - to call::
If you have the MY SKY app I think you may be able to find a number there - especially if you are a SKY VIP member
If not go this page & scroll to the bottom and expand the link need more help & scroll down

If you have SKY Mobile or SKY Talk land line then I think you can also call 150
