A few things that I can come up with: Harry Potter movie locations, Clarkson's Farm (with a lunch), Beaulieu Car Museum, Red Bull's Factory Tour and of course: London.

Ask me this about the Netherlands and without hard thinking, I can come up with 10 spots interesting for older kids. I'm sure that the UK has a lot more to offer than 10. Perhaps this will help the OP's itinerary?
If wales is on the agenda I’d recommend going to Go below near the beautiful Betws-Y-Coed
