As a EU citizen, you are entitled to visa free entry throughout the EU. You need proof that you are an EU citizen, and the easiest way to provide this is with your passport.
Furthermore, as a UK citizen, you enjoy visa free access to 83 countries - not including those in the EU. It is safe to say, you enjoy a great deal of freedom of movement even outside the EU.
