To add a VAT number to your order, you will need to ensure you are browsing on either one of our European sites or our UK site. You can change the site you are on using the flag in the bottom left hand corner of each page. You will also need to ensure that your order is being shipped to a non UK address.
You can enter your VAT number at the Address Options page when filling out your address details at checkout.
If you are ordering from the UK and delivering to a UK address, you will legally have to pay VAT on your order and therefore you will not be able to enter a VAT number at checkout or remove this charge. If you are a tax exempt business, you should be able to claim the tax back at the end of the financial year through an accountant.
