How are the winters in the UK

My boyfriend and I are always talking about weather. He cant stand the cold the winters in Pennsylvania are usually 30s and 40s f which dont bother me. He is so whiny about how cold it is and that he wants us to move to a warmer place. The winters in other places are much harsher. Like places more north like say england its winters are regularly colder than 30f. I dont know.
