Here's some info on Freesat and the channels carried etc.

It states that moving up to a 3m dish in southern Spain (where reception has normally been worse than up here) may work for a while.  That sounds like a bit of overkill for this latitude.  It would be helpful to know what size dish Cherryfarms is using.  The cost of dishes rises exponentially but a compromise size might be an option especially as it would also improve reception in bad weather for all channels.  Comments welcome.
