Maybe it's a good idea to do a standard check and an optional extended check.
I'm not sure about the standard check; are all trader VAT registered?
Nope, I'm not VAT registered. Anyone starting out in the UK I would imagine wont be as the threshold is £73000 turnover before you need to register and pay VAT on your sales. Just means that personally I can keep prices down as I dont need to recoup the VAT on the products I sell.
