Roces Rome skates full into the category we refer to as cheap and nasty plastic rubbish
. And Roces Big Cat are novelty off-road skates; you don't want these.
But anyway... any good quality skates will be fine on UK surfaces: I regularly skate the streets of Nottingham on old Salomon FSKs with <80mm wheels without difficulty. But it sounds to me like you need some decent fitness skates
, ideally with wheels larger than 80mm: i.e. 84mm, 90mm or (if you think you can handle them) 100mm wheels. I recommend something like the Seba GT
. Or if you want to stick with Roces, have a look at these
