Tried a different dealer and managed to get both sides for £76.68 inc VAT
My sone tried to change it the weekend but his wrench couldn't release the nut.
Going to take it to local independent garage to get them to do it.
Cheers for the help and advice @Percy247

Good luck. As always it pays to shop around. I am guessing it was the 17mm bolt at the bottom of the shock that was fighting you? I did blast mine with WD40 about 24 hours beforehand and probably got lucky.
