This is T. zonatus. Check the banding.
You may well be right...though i wouldn't like to call it on the elytra pattern. This can be variable in both species.
Fasciatus has a well-developed tooth-like projection on the middle tibiae whereas zonatus (aka rosaceus) projection is weak, not tooth like.
Location also favours it being T. zonatus.

I have seen rather a lot of T. fasciatus. I have never seen one with such widely separated black spots at the front of the elytra. In addition, the probability of fasciatus in Surbiton is vanishingly small.
You are probably right. I have mis-identified it because when I entered Bee Chafer in the observation I got the the fasciatus as recommended scientific name.
