Repair Shop is brilliant, just brilliant.
Dinner Ladies - Victoria Wood - always funny and has a slight melancholic/wistful air sometimes that's very comforting in an odd way.
Richard Osman's House of Games signals that work is done and it's time to sit down for tea so that's relaxing in itself.
I also like watching the reruns of Top of the Pops from the 80s and 90s as the music brings back great memories of my younger wilder days.
