Looking to avoid shipping charges?
All our tanks are available for collection ex works. Our suppliers are based all over the UK — please call if you wish to collect.
Overseas orders
International orders are welcome. Payment is by IBAN / SWIFT / BIC, MoneyGram and letters of credit. We regret that credit cards are not accepted for international orders.
A purchase order is required; we will then create a pro-forma invoice, and tanks are ordered on clearance of funds.
If you require additional export documentation — for example a Certificate of Origin, or commercial invoices certified by the Chamber of Commerce — you must notify us before completion of your order, as we will have to invoice cost and admin charges to the order.

We recommend that installers, plant hire and installation materials — excavators, aggregates and so on — are not booked until you are in receipt of the goods. Tanks Direct cannot be held responsible for costs incurred due to unforeseen delays; please see our terms for more details.
