Anyone UK based have recommendations for sourcing substrate?

As per the title, I’m looking for a specific look/colour scheme for the inactive substrate/sand for my freshwater tank. Plants will be going around the back of the tank, but I want an open section at the front dirt to the scene I’m putting together, I want an open area where I can set up the eye candy, but need some specific colouring to go there, and don’t want plants growing out of that sand at all.

Anyone know of any UK based websites that have a good selection of substrate both active and inactive?

Most of the aquascaping sites have them - I've got some really nice DOOA Tropical River Sand from Scaped Nature recently but the others I'd check out are Horizon Aquatics, Pro Shrimp, Aquarium Gardens and Riverwood Aquatics.
