To be eligible for the discount, the consumer must demonstrate that a viable, legitimate competitor has advertised the exact same item at a lower price. The FiveCarbon team will then seek to confirm the price discrepancy. The user and or consumer acknowledges and accepts that Five Carbon Limited will at its sole discretion determine whether the conditions for the Lowest Price Guarantee are applicable in each individual instance and that Five Carbon Limited, may at its sole discretion, decline its applicability for any reason whatsoever, including but not limited to, the lack of a legitimate alternative price or competitor, price manipulation, exclusive pricing agreements between particular retailers and suppliers, exchange rate fluctuations, insufficient information, etc.  If Five Carbon Limited ascertains the Lowest Price Guarantee is applicable, it will process the new price within 48 hours of any affirmative confirmation, and may at its sole discretion offer even a greater price discount. However, should Five Carbon Limited determine the Lowest Price Guarantee is not applicable, there will be no obligation to discount the purchase price, and the original purchase price on will prevail. Five Carbon Limited will then notify the consumer the reason for the lack of the applicability of the Lowest Price Guarantee, and may at its discretion, choose to either offer the same item at a concessionary price, or offer a similar item at a price lower than advertised on Under no circumstance shall the Lowest Price Guarantee be applicable to any item once it has been purchased.

Taxes & Duties +

  • VAT will be payable on all purchases within the EU, and will be tabulated based on the destination country of the shipment. This amended VAT rate will be displayed at check-out.

  • VAT may be payable for any shipments outside the EU, but as Five Carbon Ltd. does not normally ship outside the EU, please Speak to an Expert for detailed charges & guidance.

  • As Five Carbon Ltd. is an internet-based mail order company, it is ineligible to participate in the UK VAT Retail Export Scheme, and thus any purchases from within the EU to be exported out of the EU, will not be eligible for a reimbursement of VAT. Speak to an Expert to find out precise information and how we may be able to help.

  • If you have requested a special shipment outside the EU, the customs office of the destination country may require the payment of import duties, taxes, customs fees, or other charges to your order. These fees are your (recipient’s) responsibility. Once we receive notice that your order has arrived at the customs office, either the courier company or ourselves will contact you to arrange for any charges that may be due.

Payment & Returns +

  • Payment will be taken by either credit or debit card via Barclaycard merchant services. Once we receive your order, and the payment is processed, stock availability is re-checked. On rare occasion, it may be that the selected product(s) are no longer available. If this were to happen we would apprise you as soon as possible and process a refund for the entire amount.

  • At times, due to high transaction volumes, there could be an error in price display, whereby the website incorrectly posts a price. Though such instances are rare, in the event you receive a confirmation of order at an incorrect price, we will contact you immediately. You will then have the option of purchasing the product(s) at the correct price or cancelling your order. If we are unable to reach you, we will treat the order as cancelled, and any funds, if already paid, will be refunded.

  • All prices include VAT unless explicitly stated. The VAT charged depends on the destination within the EU to which the product(s) will be shipped. As VAT rates differ among EU nations, the final cost will not be tabulated until the check-out page where VAT will be updated for the delivery address. Please reference the Taxes & Duties section for further information.

  • You agree that Five Carbon Ltd. shall have no liability to you for any loss, damage, costs, expenses, or other claims that you may incur.
