Looks very much like Chamelaucium uncinatum known as "wax" to florists.

it does doesn't it. That's what I'd go for but there may be better id's.

It looks like it to me, too, and I used to sell them. Probably too tender and drought adapted to be happy outdoors in Dorset, but I have been surprised before. I do know that it needs deep dune sand to grow well.

I grew it myself in a large pot a few years ago but then it gave up the ghost I'm afraid.
