Not an evergreen...but a brilliant climber for an arch producing interest from June till November is the clematis "Bill Mackenzie"..it has a profusion of yellow flowers followed by lovely seed heads, and it is very rampant. One of my gems!

well theres a large leaved varigated ivy thats evergreen and some of the honeysuckles and clamatis stay with leaf through all if not most of the winter.

Clematis armandii is a winter one. There is also winter beauty which is a honeysuckle.

thanx for that seaburn 2 heads are better than one even if there sheeps heads my old nan used to say.im not implying your called lamb chop or anything lol.

There is some pretty Climbing Roses out there as well .
Ive just emailed Cants Of Colchester about 2 of their Climbing Roses.
They were such a lovely colour they were about £8 each , but i know it sounds expensive but they are good quality Roses

there not evergreen though are they hijuju ?

yes but theyve also put early flowering

I have just planted some jasmine for my one arch and my other arch has honeysuckle which seems to have settled very well and is now growing

If its a reasonably sunny position, have a look at Trachleospermum jasminoides - this is an evergreen climber with fragrant white flowers in summer.

ow cool you learn something every day my climbing rose should hurry up then lol.

Thanks for all your advice guys - just waiting on Argos to deliver the arch so we can go and select the climbers. Like the sound of the evergreen clematis and the jasmine. We've already got the Tangutica but I didn't know it as Bill Mackenzie.
