Car was fine until I jetwashed then started binding slightly on rear brakes any ideas what this could be and how easy / expensive likely to be.

I'd just give them a strip down and clean. Make sure the cylinders are nice and dry and move freely and there is plenty of meat on the shoes and that they are adjusted correctly. I put a small smear of copper grease on the back edge of the shoes where they rub on the back plate also.
