The UK particularly Northern England and Scotland can still have cool rainy weather in February. March and April are generally better months for the UK. If you go to the UK in February you might want to take layers like warm sweaters and a good raincoat.
In Europe in Feb you have to go a long way south to get warm weather. What is important to you? Warmth and sunshine? Lots of good suggestions from other Pelicans.
Enjoy your trip!
