You can get a Firestick directly off Amazon (UK or ES, you just have to reset the language to English for the latter but they are the same device). If you just want 100% legal content, then your Amazon and Netflix accounts from the UK will work in Spain, but you will see slightly different content because of geography.
Slightly more into a legal grey area, a VPN will let you pretend to be in the UK so things like iPlayer, ITVhub and the similar services for channels 4, 5 and UKTV will work. Right now though Netflix in particular are spotting VPNs so you might have to turn it off and on between watching iPlayer and Netflix. It is a sort of arms race between VPN companies and the content providers.
If you want to delve into the definitely not legal but lots of people do it category, then there are loads of people who will sell you a full IPTV service that gives access to all UK channels, including Sky and the like (a wander around the English Market on the edge of Arboleas will quickly find someone).
