Want to move to London, I carry a residency card from EU State and my...

[LoLi]

...husband is EU Citizen...? We want to relocate to London, we have saved enough, plan about where to rent a flat and jobs.
In my case being from a third country national but carrying a valid Residency Card, can I settle in the UK? my husband is a EU citizen from a Schengen state. He can travel and settle in any other member state, but what about me?

Can anyone tell me where to go or find out any of this legal matters? we will be in London soon and would like to know which office(s) to go and get information.

I will appreciate the help.
We both speak 3 languages, live in Denmark and prefer another country than this one. It s boring as hell here, expensive and it is simply not for us.
