No experience in the uk, but I might be able to explain. YellowJackets are wasps, I'm calling them out specifically; wasp is used for other species.
Wasps nest under the eaves of houses all the time. If they're not near an entryway, usually people leave them alone as long as the nest stays small.
Yellow jackets do not nest under the eaves of a house. They burrow in the ground (or walls) where you can't see them or the nest size. They're also particularly aggressive and will swarm if you step on their nest.
YJs are more aggressive and territorial than a normal "wasp" with the added bonus of sometimes they just swarm you out of nowhere.
