You'll need wires or a trellis, and it depends on which direction it faces, but there are so many climbers - less vigorous Clematis, (not montanas) climbing roses, Passion Flowers, etc. Try browsing through the GOYpedia pages (below) under 'C' for climbing plants.

Welcome to GOY, by the way.

Try Clematis alpina. It has lovely blue/purple flowers, just coming into flower now in our garden, followed by big fluffy seedheads.

How about a thornless blackberry. It will need to be trained along wires but you can eat the fruit. Or how about a couple or three fan shaped fruit trees, spring flowers followed by apples, pears or whatever. Chaenomeles is easy to train against a fence and does not need support unless you are in a very windy situation. It comes in white, yellow, pink, orange and red. Again spring flowers and maybe a repeat later in the year plus fruit which you can use for jelly making. You do not say whether your fence faces north, south, east or west. That will have a bearing on what you can grow.

as above lots to choose from, i have clematis, passion flower and climbing rose on my fences,

Your'e chiming with me Scotsgran. A thornless blackberry, like oregon thornless, is a good idea. Lovely white flowers, yummy berries to use in pies and sauces or make jam. Freeze well too. A lovely autumn leaf colour. An underated plant, and not too vigorous to be ovewhelming. For a quick fix Morning glory, while the oregon is getting its feet in the ground .

You don't mention whether this area is sunny or fairly shady - that will make an enormous difference to which climbers you choose.
