RHS website has a comprehensive section on windbreaks with a long list of deciduous and evergreen trees and shrubs that are suitable.

I've seen some really pretty tapestry hedges - a mixture of hawthorn, beech, holly and they are quite robust as well and probably not too expensive. I hate leylandii with a vengeance as well.

Thanks Wagger and Cammomile.
Wagger, the problem I have recently with the RHS is that so many of the old hands have been put out to grass and replaced with very enthusiastic youngsters who may give advice from a book and not the heart. I will not detract from their knowledge but prefer advice from older, dirty finger-nailed, gnarled and wind-browned gardeners.
Neverthless I will put it to them and see what they come up with.
Cammomile, thanks, I had completely forgotten about Holly, and what an excellent tree it is. Also, when you said Beech, I thought Hornbeam. Another quick growing example. Food for thought. Many thanks to you both.

Holly, Yew, Photonia, Laurels are all evergreen. Adding an evergreen with a deciduous tree like hawthorn, Blackthorn and Hornbeam will give a year round hedge and wind filter.

I was wondering abut blackthorn as it has such lovely blossom so early in the year, but be aware that it does sucker and run!

But at least you get sloes for the gin!

Many thanks KIldermorie, Stergram and Melchisedec, Much food for thought. I will make a comprehensive list of all your suggestions and incorporate them all into the final hedge. Southportsmith
