Delivery and dispatch

Your purchase will need someone to sign for the package as all items are too large for a standard post box. Please consider whether your home or work address is best for this.

Your order will generally leave within 3 working days from being placed, unless otherwise stated on individual product listings. We ship orders Monday - Thursday. Orders placed after 2pm (UK time) on Thursday will be dispatched the following week.


We offer a 12 month back-to-base warranty on all our grinders. Contact us if you feel there is an issue and we will attempt to diagnose the problem. Failing that, we'll ask you to return the grinder to us and we will either repair or replace and return to you at no cost.

When instructed to return a grinder, please ensure that the item is packed securely and that the crank arm is not making contact with the body of the grinder. Otherwise this risks permanently damaging the surface of the aluminium in transit. We cannot accept responsibility for items that have been damaged because they are poorly packed. Putting the grinder inside a jiffy bag is not enough! Please also include a note or return address so we can identify the package easily.

Return address:

Knock Products LTD, 37 Assembly Street, Edinburgh, EH6 7BQ


If you change your mind or feel the product is not suitable, you have the right to return goods in the condition and packaging in which they were sent within 14 days, but only if the item remains unused. You will be liable to arrange the return post. If the item/items are returned to us in good condition then we will process a refund (minus outward postage).

Items must arrive at Knock in the described condition and it is the sender's responsibility to ensure this via the use of an appropriate packaging and shipping service. You are strongly advised to take suitable insurance in your postage method against damage or loss in transit.

3rd party items sold by us which are not Knock's own products (for example Aeropress, scales, filter baskets etc) will also only be accepted for full return if the packaging is unopened. In the event that the seal is broken these items are considered used and cannot be re-sold as anything else.

Minor cosmetic marks on cosmetically 2nd-graded items will not be deemed a valid reason for return under warranty.

Please also note that we reserve the right to charge up to 10% restocking fee for items returned as a matter of choice rather than function. This covers charges we will have paid in processing your payment, costs for new packaging where appropriate or in rare instances losses incurred due to transit damage or re-selling.

We will refund you completely, or send a replacement item if the goods have arrived damaged or there is a problem or mistake caused by us. We aim to be as fair as possible in this and will seek to negotiate with you to reach a happy settlement. However we reserve the right to defer to our payments management system (Paypal/ Stripe etc) to assess the merits of any claim against us for a refund.

VAT, local tax & customs duty

For customers buying from within the UK, all our prices include VAT. For the rest of the world, you may be liable for local customs charges, taxes and duty. For the EU, our delivery fee covers all import charges, duty and taxes with delivery door-to-door. Please note we cannot be held responsible for delays caused by customs - please check details with your national authority before purchase if you are unsure.

All purchases made by customers in the European Union will be charged a flat rate IMPORT VAT & FEES PAID delivery charge which ensures that DHL pre-clears your goods through customs before they have landed, meaning you have no delays to your door and no further fees to pay.
