Delivery information

UK Stock Holder

We are the sole UK distributor for KAYSUN in the UK. We hold stock of all the popular units in the UK so that we can reduce the lead times down to, as quick as, next working day, with same day collection possible for urgent jobs. For larger orders delivery could take up to 5 working days. 

Familiar Logistics Companies

Smaller items are dispatched with DPD/Yodel on a next working day service. We will inform you that the item has been shipped, the courier will then send an update with the consignment information, and follow up the next morning with a 1 hour delivery slot. Should you not be available for whatever reason the courier have a number of convenience options to choose from.

Pallet Delivery

For slightly larger products the delivery will usually be scheduled in with you. Larger products such as split systems, multiple items, or larger evaporative coolers are palletised to ensure they arrive safely. Tracking for palletised deliveries is limited to a day slot but we will endeavour to make this as convenient as possible. We have limited control over 3rd party couriers but you should find the driver polite and accommodating.
