Could be Viburnum tinus.

It is indeed

It is Viburnum tinus!

Pruning time for these is May/June.

They make a nice hedge too. :o)

Thank you very much for all your replies....now I know what it is...has it got a "common"name?

Just had a look at a webpage on this plant:
http://www.findmeplants.co.uk/plant-viburnum-tinus-1158.aspx

It says to prune in winter...so I am a bit confused???

It does not have a 'common name' as such. And pruning is generally done after the flowers have finished, which may be any time from mid-winter to mid spring.

The main thing is to do it before it starts growing new wood because if you cut that off it won't flower the next winter (which I discovered the hard way...)

Thank you both.

So can I prune when the flowers have died off even though we are coming up to winter?

It should continue flowering through the winter. If you do it now you may lose flowers you would have had. better wait until about March. why are you desperate to do it now?

Thank you.
