Please help me identify my enormous hedge

[EspressoX10]

We bought this house 18 months ago and have done nothing in the garden. It's a large corner plot and this hedge wraps most of it.

It's so pretty and the wildlife seems to like it. I really want to plant more of it in the remaining area, but have no idea what it's called! Can anyone help please?

Is it some sort of escallonia?

Yep escalonia.

Wow thanks! I'm a novice and trying to learn as much as I can, so I'm in awe of people who can just identify plants like that. One day...
