Thanks again.
Would something like this be suitable? The bay trees are currently around 1.1 meters tall.

Gardman supply most garden centres with pacekts of horticultural fleece, if you can fight your way throught he christmas department, they will have packets of fleece (spunbonded polypropylene) like the farmers use to advance or protect crops. it lets the plants breath, creates a little microclimate and keeps the wind off. you need to tent it so wet fleece does not lay on foliage and freeze. that brown stuff would i'd imagine cut light levels right down so is not ideal for an evergreen.
if they are clipped and full at 1.1m, then bamboo canes make a cheap wigwam
