No way of identifying that rose at this time of year Sam - we need to see flowers - colour, petals, shape, bud shape, stamens colour of young foliage, all sorts of things and then there are so very many different roses.
However, to rejuvenate it, I think I'd cut out all the weak twiggy growth, and cut the main stems back to about 18" tall, pruning to an outward facing bud, but I'd do it in late February, early March. Not now.
Give it a mulch of well rotted manure now (around it, not touching the stems) and after pruning in the spring give it a feed of Fish, Blood and Bone.
