Maybe your BF should sort it out to bring you in UK with him. If he is in love with you and you want to be together the best way is to apply for fiancè visa or spouse visa. Forget the job hunting at the moment. If you and your fiancè get plans to get married then you can apply for spouse visa which given will enable you to work once you get in UK. Otherwise work permit is soooo difficult to attain (unless you are a very high skilled worker), specially now with the immigration flood of new EU citizens.
