or from a standard ceiling rose ( yours may be red and black not brown and blue depending on age )

the 2 core you have is no use.. except as a pull wire to pull in a new 3 core and earth
you need to connect the brown to 3 4 or 5, the grey ( sleeved blue ) to 6 or 7, and the black ( sleeved brown ) to 2.
at the fan you wire the brown to the L, the grey ( sleeved blue ) to the N, and the black ( sleeved brown ) to the SW ( switch ).
you should wire through a 3 pole fan isolator so you can turn the fan off to dust and clean it while still being able to have the light on...
