It looks like a holly. My first thought would be a 'Burford' Chinese Holly, but there may be better candidates for Scotland.

Could it be one of the Laurels? Not sure about the flowers being right though.

Wrong time of year for holly to be flowering so if photos taken now then not holly.

It is a Laurel. Variety will depend on the fruit colour (red/burgandy/black etc)

Yes you got there before me Kildermorie a nice Laurel Scottish.

Looks like an Aucuba of some description - its not A. japonica because the leaves are plain green, but the stems and flower form denote Aucuba of some description. Are all the leaves plain green and how tall/wide is it? Do any of the leaves have toothed or shaped edges, or are they all plain and smooth like these?

In response to all your comments:
All these pics were taken yesterday - so we have flowers, green berries and still some red berries left over from last year. This is the first time I have noticed any flowers (4 years)
Leaves are all green, the older leaves are dark green,some of them have a tooth edge - can be quite jaggy..ouch!
It is currently around 6ft high and 3ft wide. I have it trimmed twice a year to keep it's shape. Some of the trunks are around 6 - 8 inches in diameter.
It's a lovely hedge, but feel it could do with a bit of a feed as the kittens used it as their climbing frame when they first went out to play and they have caused it to loose quite a lot of leaves.
I can post more pictures if this helps.
Cheers Angie

A pic of the leaves with toothed edges would be useful - all the photos I have here of green leaved Aucubas show toothed leaves to varying degrees.

Ok Bamboo, I will post another question with the close up of the leaves

tugbrethil - Scottish has posted another pic showing spiny leaf, rather than toothed - I think you're right, it is a Holly, but more likely J. C. van Tol

Was going to update you all but Bamboo beat me too it!
After seeing a close up of the leaves it has been identified as Ilex J C van Tol. Have looked on google and it is certainly a match.
Didn't know my spined leaves from my toothed leaves :)
Thanks for all you in put guys x

The four-petalled flowers are a definite indication of an Ilex. Note that I. cornuta often blooms in late summer or early fall.

I have googled both images and compared Tugrethil. I. J C Van Tol is closest.
Mines is probably flowering at the wrong time as it has never been pruned properly since I inherited it 4 years ago. I just get the man who trims my privet hedge to give it a tidy up with his electirc hedge cutters!
At the moment there are flowers, green berries and red berries. Thanks

Flowering when you don't expect it is common, specially on hedged plants - when conditions are right, they take the opportunity to flower, even if its only 2 or 3 flowers, and then set seed, in this case, in the form of those lovely berries. Like most everything else on the planet, its primal drive is to reproduce itself...
