Is they a website that gives you free vat, on UK amazon orders for free
I'm not aware of any legitimate website that offers free VAT for UK Amazon orders or any other online purchases. VAT (Value Added Tax) is a tax applied by the government, and it cannot be legally avoided through third-party services.
If you are a business and registered for VAT, you can reclaim the VAT you pay on your purchases. However, individuals purchasing for personal use will generally be required to pay VAT as part of the purchase price.
Always be cautious of any website that promises to provide VAT refunds or discounts outside of standard legal processes, as these may be scams or illegal schemes. For any VAT-related queries, it's best to consult the official HM Revenue and Customs (HMRC) website or a tax professional.
