      2. General Delivery information

       

      We're a Manchester based company and ship to the UK at our standard rates. Please get in touch requesting the delivery surcharge value  if you are based in the Highlands or a UK island. 

      We no longer support ordering from the EU and Northern Ireland through the website. We can support ad hoc orders with limited liability.

      Our design and Prestige range is available in the Netherlands, Ireland, Belgium, France, Germany, through our distributors.

      Stock items will be dispatched on the day of order, if ordered before 1pm.

      Letters are sent 1st class. 

      Parcels <2kg are shipped with Royal Mail 24 with the following target delivery times.

      Guaranteed delivery can be arranged by advance agreement. This agreement is back to back with the courier and we will not be liable for any delays as per our terms.

      A loss/replacement can only be pursued in line with the target delivery times of the courier or once the courier accept loss. 

      Bulky items (and pallet deliveries) are dispatched within 2-15 working days. We will request a contact number if this has not been provided at checkout. 

      Some items are made to order (bespoke) and details are given on the listing for dispatch times.  If for any reason we anticipate a delay on our normal dispatch time we will contact you to let you know.

      Occasionally there are delays. We shall not be liable for any direct or indirect losses, costs, damages or expenses incurred by you or any other person for any delays in delivery.

      Missed deliveries where attempted delivery has been made usually result in re-deliveries the following day. The customer is responsible for organising re deliveries by contacting the courier direct. 

      Parcels/deliveries can only be "left out" if the delivering company allows that option. Parcelforce, for example, do not allow a parcel to be "left out". 

      We are an environment centric business and as such we try to minimise our waste. Our packaging is usually recycled and/or recyclable and we make efficient use of packaging to minimise wastage.
