@Bowdon+boy simpke explanation is that your Spanish property has a full fibre connection but your property in the UK probably doesnt. What connection you have in the UK depends on the Openreach (BT as was) line if you still get your service over a copper line then the speed dependson its length and condition nothing Sky can do about thst. Openreach are upgrading their network to full fibre when Sky will be able to sell you a connection up to 900Mb/s.something around 70% of addresses have access to gigabit fibreceither from Openreach or another provider. The 30% thst cant are primarily in rural areas where costs of running fibre is much higher so not commercially viable.
Full fibre lines are far more reliable so cost the operators less to support so prices are often lower. My 500Mb/s Sky service costs £32 per month
