I think Hugh W is more 'comfortable suburban Dublin Protestant' than 'Anglo, but the cousins got the Palladian mansion', but I could be wrong... 
He always seems nice, actually, insofar as I get a sense of him from TV. And he gave a talk at my local school of architecture a while back about restoring derelict city centre properties and made a lot of sense.
There was a particularly irritating Co Laois Tiktok airhead who inherited her granny's house on a previous season of The Great House Revival, and he was very kind and warm to her, even though she lurched from (1) hysterics over clearing anything at all out of the house (granny was clearly a hoarder, and the house had been left untouched since her death) because of warm feelings about her granny and her father, who had died young and whose room had been preserved, to (2) suddenly, after all that anguish, knocking down all internal walls, gutting the house and not allowing more than two stools, a sink and a vase from the old house to sully her completely standard white-walled newbuild with pink accents, and a big glass-walled extension kitchen and zany wall art.
I mean, it was a perfectly nice house, but after hearing her say that the challenge was going to be finding a way to merge honouring the granny's house of her happy memories in a renovation, it was a bit odd to see that the final house was internally a new build with absolutely no sense that anyone else other than a 25 year old Tiktok influencer had ever lived there. Hugh was immensely tactful, even though all the footage from all but the last ten minutes of the episode had clearly been filmed specially from the angle of 'young woman tries to find a way to incorporate the family past into her renovation'.
He's good at TV, and I think it revived his career. He's a recovering alcoholic who lost a lot in the crash, and I think relapsed, and I think TV became his thing as he got back out there.
