Q.What’s This On Cherry Laurel Leaves?
Hi I’m very new to gardening and this laurel is my first and only plant in my garden. I will be buying more but my only plant has these black dots underneath and some leaves are looking like they’re being eaten. I don’t want to buy more in case it damages the new plants. Please see pictures

I see a powdery mildew infection, a bacterial infection, and insect damage.
Likely, two of those came from too much moisture, humidity, or watering. The insect problem doesn't help either.
These problems will definitely infect anything else near it. You will need to take off any black spotted bacterial growth, and treat the powdery mildew with a fungicide, while using an insecticide to get rid of the insect issue.

I only purchased this plant two weeks ago from a garden centre. Would you ? Am I best taking it back?
