Why am I not surprised you like BBC stuff 
If it's on Britbox I recommend checking out Grand Designs, Homes under the hammer and an older show called Ground Force. Also, British cooking shows. I liked Rick Stein and Nigella Lawson. They have a similar type of appeal to the shows you mention.
I have enjoyed watching British TV for years. My wife and I used to faithfully watch the sitcom "As Time Goes By" with Judy Dench. "Doc Martin" was another great show where we watched every episode.
Nigella Lawson's show was one of my wife's favorites. I think I still have some of Nigella's cookbooks from my wife's collection. She is a very attractive woman with an excellent figure. I have seen Grand Designs and liked it a lot. -Not watched Ground Force or Rick Stein though.
Have you ever seen the British cooking show "Two Fat Ladies"? It was another great one. Smoking cigarettes and impromptu singing while cooking was the trademark of the not at all PC show. One of the 'fat' ladies Jennifer Peterson always seem to be a bit tipsy.
My best friend introduced me to "Absolutely Fabulous" a totally over-the-top comedy.
