Hi all, I am planning on building my first VTTC and I got all the parts required for it, however I am having trouble finding an supplier that sells 3" or 4" diameter white PVC pipes in UK. I keep finding loads of unwanted stuff when I search on google.
So my question is: Are they any suppliers in UK that sells large white pipes? Will any other types of pipes work? I am not too sure about grey pipes but I do know black pipes contains carbon.

You can get pvc from a plumbing supply. However, I would use acrylic. I believe it has properties better suited for high voltage, and this is what I used. Someone who is really into TC can elaborate. You can get the acrylic cylinders on Ebay.

I wouldn't worry about it, grey PVC will be fine. From reading various posts, people have favourite materials and all materials are going to have disadvantages as well as advantages and the impression I get is that it doesn't really matter too much what you use as long as it doesn't have any any anti-static additives etc.

Here's all the different sizes / types of poly pipes you could ever want in the UK:
Er. where? It's just a list of companies vaguely related to agricultural drainage mostly ditch digging and concrete pipe AFAICT. Only one of the companies listed seems to do any sort of PVC piping but their site was a pain to navigate so I didn't bother looking in depth. IME most of those "industry link" sites are a waste of time. A carefully crafted Google search is usually far more effective.

You could also use a heavy cardboard shipping tube! When you varnish it, the varnish will impregnate the cardboard making it very strong! Might be easier for you to find! Otherwise any home improvement store should have the standard white pvc drain pipe relatively cheap.

Id agree with Dr. Electrons,
I use this method nowdays, for an 8 inch coil, and cardboard tubes (especailly sonotube) is so cheap and readly avaialable, anywhere from 3 inch daimeter to 2 feet+
Using spar urathane and other sealants, along with alot of sanding, its a bit of an effort more then PVC, but the results are well worth it. if one was to go overkill, they could fiberglass the sonotube and make it more effective, but it apears epoxy was plenty.
but as said, sanding the tube is essential especailly if there is any writing, labels, markings etc, I never had a flash over, but I heard that this inks can be conductive, so its just something to keep in mind.

From personal experience Essex tubes are very good for cardboard tubes . They'll wind a one off to your spec. without it costing a fortune. I got an 3 meter long tube about 30cm diameter with a 5mm wall thickness delivered for about £30. I believe they can also add an inner/outer/both plastic layer if required.
