Using Bing streetside (which is allowed in Openstreetmap, unlike google streetview), which you can find in the data layer under "overlays" on the right hand side of the screen when editing on desktop (if you weren't aware), I don't see any gates, making me inclined so change the road permissions to access=yes, motor_vehicle=private for Broomfield Hill & Close, but I will await your confirmation before doing so.
