The exceptions in western Europe is France and Germany.
There are countries in the EU where people speak less English than France or Germany. Italy is an obvious example here. As a general rule, people in countries with "small" languages will speak better English (Scandinavia, Finland, Benelux) than the ones who speak one of Europe's major languages. Which is logical because if you only speak a small language the incentive to learn another one is big. That being said, if you seriously consider moving to another country, you should always learn the language, otherwise you remain an expat and will never integrate.
