What other rabbit breed to go for? UK?

netherland dwarfs are a good choice for you since they are the smallest domestic rabbit breed. be aware that alot of them have aggresive personalities, but not all (i have a netherland dwarf that is quiet and loving) also maybe brittannia petites. they are a rare breed so it may cost alot to get a good breeding pair, but they are small, energetic, GREAT for showing, and come in variety of colors. lops are also a good way to go too since they have always been popular as pets and still are even with the growing demand for lionheads. i have 2 mini lops and cant get over their cute little faces
