Unidenified climbing plant

Question

Hello, my girlfriend and I bought a couple of these climbing plants a few years back. We thought they were Clemetis. I wonder if you could tell me is this correct. They have been in for about two years now. We hoped they would flower but haven’t. They just produce an abundance of green leaves. We don’t know which type of plant they are and when they should be pruned. A very novice Gardner. Andy .Thanks in anticipation I’ve uploaded a photo below

It does appear to be clematis, but it is really hard to tell at this point. There are a few reasons why these will be reluctant to flower. This article will help: https://www.gardeningknowhow.com/ornamental/vines/clematis/growing-clematis.htm
