not really. what you've got there is a tape and joint wall.
the plasterboard (probably with an insulation backing, because its an exterior wall), is stuck to the wall with board adhesive, and then the joints are filled with a gyproc filler. a paper strip is run down the seam and another layer of filler is applied. this is sponged flat while wet, or sanded once its dried. it looks great for a few years, but the surface is nowhere near as durable as a plastered wall.
it's basically a cheap way of doing things. if you've striped off any wall paper and its flaked all the paper of the plasterboard, this can be unibonded and then skimmed over. easy.
looks like you'll have to pay for it yourself tho. i doubt it would cost too much. if its just the one wall with a couple of window reveals, id say its an easy days work for one spread. plenty of change out of £200 inc materials.
