A building site must be "Plasterboard Ready" for a DTS delivery to take place (see video). We are not completing DTS deliveries to any site that is not "Plasterboard Ready". See here the bulletin Requirements to Move DTS Delivery Dates Out If Sites Are Not Ready.  If you know a site is not going to be ready on the scheduled DTS delivery date please make contact via your Winstone Wallboards Area Sales Manager to arrange for the delivery date to be rescheduled for when the site will be ready, and we will arrange delivery for around that date.
