Hello Chris,
We have lived here for several years and I am speaking from experience and not from anyone trying to sell you a system.
There are several options available to expats and that depends on many things, firstly and the most important is affordability and second is what you exactly want in terms of channels.
One of the cheapest methods is to have a large dish where(if part of a community)everbody feeds off, which should be a one off cost and no monthly subs. This will give you most British channels and some movies, however no live sport, ie premiership football etc. The other option is you can have a rebroadcaster ie Torresat to install a small dish for you and you will receive eurosport and some live games in addition to all the other channels. This will cost you 21 euros pm. There are other options but they will obviously cost you more. Please feel free to ask any other points you are not sure about.

Hello John,
Thank you for an depth analysis on this subject. Where we are renting at the moment it is mainly Spanish residents and other nationalities,so I don´t believe they have a large dish on the roof solarium. But your open information has given me a better idea of what we can do. I will be talking to the President in my broken Spanish and see what he says.
Will let you know how I get on. Having said that the Torresat system could be a possibility. Regards Chris
