New live? UK Everyday life and customs

Hello 🙂
In future (August - September 2018) i plan to move out to UK (England, near Leeds), the reasons? Different, but i want to start new live, find a job, learn and improve a language.. but i'm thinking about the opinion about foreigners, any people from UK can tell me?
Second question - any advice before flight to England? What customs is worth knowing?

up 🙂 too want to practice english with other people!
