Well it seems costwise its dearer up here, and 40 quid includes the kill, transport to butcher and butcher cutting up to my request (It also was hanging a couple of weeks!).
Storm, I think most farmers around here (unless you know them personally) will not sell you a lamb just for slaughter, but probably will do so if they know you. I have a Shetland hogget wether that will need to go to slaughter in early autumn as one of his horns is growing inwards, and it needs regular cutting, so I think I will not keep him over winter. If you are interested let me know, I am near St Boswells, and we could probably take him to Gala for you (when we take some other in too). Gala delivers to most butchers in the area.
