The BNP, if it is similar to the French FN, wins support among the working class by addressing it in frames people from the working class understand, and then directs that support towards racism. (Not to say that the people that go to the far right were not racist to begin with : many of the Communist voters in early 1980's France were in fact racist, but the PC only marginally used that racism) (Also, the way the FN won votes among the working class wasn't the same way as it earned the small shop owner class)
