No... never. Why would you???????

you must be reading uk gardens sites.

I've never pruned cucumber vines but have read that doing so forces out side branch vines which may result in better cuke production.

Pinching off the growing tip of peppers plants makes them branch off and you will get a more compact plant with increased production. I've never pruned cucumber plants but the jungle of vines by end of summer makes me think I should look into this practice.

Didn't read it just saw a video of it and I'm not sure if it is UK or what, but if I remember right the video was from Springhill Farms.

I am growing cucumbers as I love cucumber sandwiches. My parents when they had a garden also grew cucumbers and zucchini. And they never have pruned them. A lot of them are also growing zucchini. So I am thinking I could swap one of my cukes or 2 radishes for a zucchini :) Also growing 2 tomato plants, some chives, a cherry tomato plant and rhubarb. Might try planting the lettuce tomorrow but not in the garden as we have chipmunks, squirrels and a rabbit running around out the back. So I bought a planter that will fit on the ledge where my bedroom window is. I can look right out at it when I am sitting here on the computer. It is higher up than my living room window ledge that I have the petunias on.

I've heard that people don't prune peppers because it makes them take longer to produce, have any of you had experience with that? I've been thinking about pruning them, but I'm afraid it'll make it too long to get to harvest, since I don't know how long it'll set them back?

Here in Zone 6, I start my peppers under lights in late March, and by early May the plants are typically 4-6" high. At that point I prune once leaving 3 sets of leaves. this forces the plant to branch, and makes for a shorter, sturdier plant to go into the ground at the end of May. Flowering occurs pretty quickly: 2-3 weeks post planting for the sweet peppers, 4-6 weeks for hot peppers. I prefer red sweet peppers (Marconi, Crest, Lipstick, Carmen, and Corno di Torro), so my first harvest tends to be in August.

Deer pruned some of both a little bit, the Japanese style cucumbers responded very quickly by growing side branches, so maybe it "helped" in a way. The deer trimmed my 'Corno di Toro' peppers for some reason, they do grow too tall and fall over anyway, maybe that helped too.

I've never pruned cucumbers with more than I can use or give away, but this year I have them growing up a 6' fence and the deer are pruning anything popping through to the other side, I will see.

I prune the first set of leaves when I plant and some times the 2nd set also. I also remove the first three flowers from the plant because after they set the plant basically stops growing until they are picked delaying growth and in the long run you get many more peppers if you pull the first three. Some say the first 5 but found no difference picking the first 3 and the first 5.

Corno di Toro's are my favorite once they turn red and also planted some yellow Corno Di Toro this year. I make stuffed pepper boats with them that sink green bell peppers in the water and will make tp freeze enough for the winter.
