Buffer vessels are delivered direct to site from the manufacturer, UK Cylinders. Popular sizes are usually available from stock, but some sizes are made to order, so the lead time depends on the size you choose.
After you order, we check availability with UK Cylinders and contact you with an estimated delivery date. If your buffer needs to be made to order, we will confirm the lead time with you first and only place the order once you are happy with it. If it does not suit, you can cancel for a full refund.
Once a made-to-order buffer has been confirmed with you and placed with UK Cylinders, the order cannot be cancelled. We arrange the delivery for you.
