We offer next day delivery on most of our standard products (excluding hazardous and those sent on a pallet) – this applies to orders made before 4pm from Monday to Thursday. Orders placed after 4pm on a Friday and across the weekend will be shipped at the earliest time the next working day. As all products are not guaranteed to be in stock, our standard delivery is a 2 – 5 day service (excluding weekends and bank holidays).
Please note that some goods are palletised or marked as hazardous. When delivery takes place, please ensure ample space is available and unloading of the products may also be required (this is due to articulated lorries and the requirement of a forklift to unload the vehicle). Please be aware all palletised goods must be signed for on receipt of the delivery. If you are concerned about the goods you are ordering or possible delivery restrictions, please let us know when the order is placed.
