is Oliver effectively subsidising Ed’s business?
Yes; he has been from the moment that he gave Ed the cows to start it with. And charged him a peppercorn rent for the land, on the pretext that Ed was doing him a favour by looking after Oliver's cows for him.

What’s the history with Oliver housing the Grundys?
When Joe and Eddie, tenant farmers at Grange Farm, went bankrupt in 2000 after not paying rent for several months, they were evicted by the landlord, who then sold the farmhouse and fifty acres of land to Oliver, whose intention was to be a gentleman farmer. The Grundys were rehoused in Borchester for three months, then moved back to Ambridge into a caravan on BL land and then into a cottage belonging to Jack Woolley.
Ed was a nogoodnik and petty criminal with a drug habit; Oliver picked him out of the gutter and put him onto his feet, employing him to look after Oliver's herd of Guernsey cows. After a while Oliver allowed Ed to have the cows and rented the land to him cheap. After a while he over-extended himself and lost that business, but managed to sell the cows (none of which were his) for a profit which he spent on a tractor. In 2016 he also started to breed Texels on Oliver's land, which he still rented.
Meanwhile Eddie, Clarrie and Joe were living in Keeper's Cottage, for which Jack Woolley charged them £500 a month (starting in 2001) for the three-bedroomed house. After Jack's death on 1st January, 2014, that house was inherited by Hazel Woolley, who didn't evict the Grundys until after the Great Flood Of 2015, during which they were flooded out and went and lived rent-free in Grey Gables for several months. (With their ferrets. How we all laughed.)
Oliver and Caroline, owners of Grey Gables and Grange Farm, went to Tuscany and decided they liked it there, so after a break-in at Grange Farm they asked Ed, who was there every day looking after his sheep, to keep an eye on the place and eventually to house-sit for them (he and Emma had housing problems as well). Then Grey Gables wanted the older Grundys out so they could let the rooms for Christmas and Joe (aged 204 – oh, all right, 94) was going to have to be put in a horrible B&B at the expense of the council, so Oliver said the senior Grundys could live at Grange Farm until they found somewhere. Once there, Joe settled in and started talking all the time about how all he wanted was to die in his real home, and like a sap Oliver allowed them to stay, though after a year or so of them freeloading he and Caroline did start to charge them all rent because they planned to buy a villa in Tuscany and needed the money.
After Caroline's death, the Grundys very kindly allowed Oliver to live in his own house, on sufferance. In fact they positively insisted on him coming to them for Christmas that year even though he didn't want to, and managed to make that be him now being in their debt.
