We (Wales) certainly don't get headage (which I assume you meant by 'hedge') payments, and we didn't in England either. Just a set payment per acre in England for a good few years now, and Wales (at a lower rate on productive farms 'cos of being Fooked by the Uplands) coming into line by 2019.
Yes 'headage'. I know a guy who at the time of IACS based to SFP was running about 1500 acres of land and 1000 beef cattle. He got 'x' per acre for the land dependant on cropping and 'x' amount per animal. The x + x = y and 'y' is what he was then paid after the change to sfp and immediately sold all the cattle. Today he still gets around £500k/year even after the various reductions.
