Plant ID and diagnosis

Hi anyone

I'm hoping someone maybe able to help, we live on a new build estate and in my next door neighbours garden he has several of the shrubs in the photos. In the past few days we have noticed the tips of the leaves are going black.
I was wondering if anybody knew A: What the plants are? B: Whats caused the tips to go black? and C: Should we cut them back and/or dig them out?

Thanks in advance

Gareth

I did wonder if it was frost damage, we had a couple of days frost last week. Thanks for your help New Shoot.

It's definitely Grisellinia.

However, I have my my doubts about frost damage.

Most of ours, that was in a hedge, was killed in the severe winter a few years back.
But I don't recall it ever looking like that.

Has it been sprayed with anything recently, such as a strong foliar feed?
