Does anyone know what cactus this is please?

To my naive eye, it looks rather like my Stenocereus griseus (or maybe S. montanus)?

I would agree with Stenocereus.

Attached is a photo of my Stenocereus pruinosus

It's Pilosocereus pachycladus.

Thanks

To be more precise, it's probably in fact 4 Pilosocereus pachycladus, you can separate them and pot them as separate plants if they like. This species (and Pilosocereus azureus) is commonly sold like this, as multiple plants grown together in a cluster although they are separate plants.

Plants like this can be difficult to judge at shows because the exhibitor is probably unaware there are four plants in the pot and there is always the very unlikely possibility it's a damaged seedling that has branched. It's common practice in Holland to pot plants in clusters as it makes a better looking garden centre plant. If it's not a prize winning plant at shows I prefer to ignore it rather than mark it as NAS though I'd probably let the exhinitor know.
