I'm not sure I've ever seen these described as climbing plants in the way I think of climbers.
However, I think I've seen blackcurrants trained against a wall - possibly espaliered - so it may be worth Googling espalier and wall training for blackcurrants.
Similarly, I can't think of a reason why you couldn't train an autumn fruiting raspberry to a wall or fence. People do grow them in large pots as well and train them around canes.
Does that help at all?

Have just looked up the varieties you bought and neither appear as climbers. A blackcurrant is a bush that can be trained against a wall or frame, and the variety of raspberry you have are canes that need to be tied to a wall or fence. Both need training as neither will do this naturally. Hope this helps.
I grow autumn bliss they are on the small side and not a heavy cropper but very tasty all the same. They don't seem prone to disease or pest and need a minimum amount of support when fully grown especially if in a windy situation.
I picked these up as a spontaneous buy as they said climbing and never heard of that I already bought blackcurrant months back and same with raspberry, I was just looking at the info on plants and the blackcurrant grows to 1 metre that's like any blackcurrant and the raspberry grows to 1.5 metres so I think it's a case of taking them back in the morning and informing them of there error, slightly let down as I was just praising morrisons on there variaty of plants.
I don’t know about the blackcurrant, but I have one Autumn Bliss and it doesn’t need much support, as Barry said, but it does send out suckers that pop up everywhere so I think it would be tricky to try and contain it against a wall as a climber. They are called ‘bushes’ for a reason, so the description of it as a climber is pretty misleading I would say!
