As I can usually order small things (£20 an under) on a VCC with no hassle, but they often ask for proof of address for orders over £100.

This is the email I received on one account. This was for my actual CC.

This Is a little confusing. You've said the message was only for your CC, but then mentioned they've asked the same for your VCC.
Please clarify.

So I've used my CC for a few SE's and they probably caught on, hence they want to confirm my address.
I've created a new account with a VCC instead, however they have not dispatched my order or taken my payment, which leads me to believe they will send the same email in the next 24 hours. As that's what happened with the CC order.

I'll update you if they contact me

Now It makes sense.

Please do so- keep us updated.
