Due to the increased demand of carrier deliveries over the Christmas period, we are unable to guarantee a Next Day service outside of our own Van Delivery Area. Please keep this in mind when ordering and order in advanced.
We will close for the Christmas period on Friday 19th December at 4.00PM and re-open to the public on Monday 5th January 2026. The last day for van and courier/carrier delivery will be Friday 19th December with van deliveries recommencing week beginning 05/01/2026 and carrier delivers from Tuesday 06/01/2026 onwards. Please bear in mind that there will be a backlog for the carrier services to catch up on so there may be a delay of a day or two before normal next day service is resumed properly. May we take this opportunity to thank you for much valued custom and loyalty throughout 2025 and wish you all a very Merry Christmas and a Peaceful and successful 2026.
