Delivery Policy

Here at GZ LABORATORIES UK, we pride ourselves on excellent customer service.

We know that you don't want to wait days for your order to arrive. That's why we send every order within the UK Mainland by Royal Mail via Special delivery, which guarantees that you should receive your parcel the following working day after it has been despatched.

However, although we promise to despatch your order quickly, it should be remembered that delivery is not guaranteed within this timescale and parcels can occasionally take longer to reach their destinations. Parcels sent to Northern Ireland, the Isle of Man, Isles of Scilly, the Channel Islands, certain parts of Scotland, Europe and the rest of the world will usually take a little longer to arrive.

How will my parcel be sent UK mainland?

Based upon the weight of your item(s) purchased the postage costs are automatically calculated and displayed in our shopping basket and sent by Special Delivery via the Post Office which guarantees next day delivery after dispatch. It also allows you to track and trace the parcel on line.

How will my item(s) be sent to Republic of Ireland & to Western Europe

Based upon the weight of the item(s) purchased the postage costs are automatically calculated and displayed in our shopping basket and sent via the Post Office using their International Track and Signed service which allows you to track and trace your parcel on line.

Please note our shipping charges do not allow for any charges levied by Customs in the destination country, nor do we accept responsibility for paying such charges.

How will my item(s) be sent rest of the World?

Due to the fact that Royal Mail Air Mail is not tracked and can sometimes take up to 1 month for delivery, we have taken the decision to send all items to the rest of the world by Courier. This does mean extra cost but a much better and more efficient service. The costs can be confirmed upon request.

Please note our shipping charges do not allow for any charges levied by Customs in the destination country, nor do we accept responsibility for paying such charges.

Please note we have made every effort to make our shipping charges as accurate as possible, however occasionally the amount charged may be insufficient to cover the cost. If this is the case you will be given the opportunity to either pay the additional amount or alternatively we can cancel your order and issue a full refund.

How will I know when my order has been dispatched?

When your order has been dispatched you will receive an e-mail notification advising of this.

Help! I haven't received my parcel, what should I do?

Contact us - we will do anything we can to help. If an item sent by Royal Mail has not been received it can often be found at the local sorting office awaiting collection. If not, the Royal Mail has a specific procedure that we can follow in the event of a missing parcel.

For deliveries to Europe and the rest of the world, if your item is not collected and is returned to us then we will issue a refund minus the cost of postage to GZ LABORATORIES UK. If not received, these items will not be deemed to be missing until two weeks have passed.
