I would encourage UK based people to join the various pressure groups and political organisations (e.g. the Liberal Democrat party, the Open Rights Group etc) that campaign (and in the case of the LibDems actually vote in the commons against) against the sort of Stasist legislation that Cameron's government is trying to push through.
Do remember that the UK's informal version of a constitution does not allow the Lords a lot of scope to change or reject e.g. the Snoopers charter. (It is convention that the Lords doesn't oppose things that were in the ruling party's manifesto..) Therefore there is not a lot of time to act on these issues.
