Please ensure the product you are ordering is the correct size and suitable for the purpose. Special order, bespoke and non-stock tanks are not returnable. If you order a tank and find it is too big, too small, or unsuitable for your requirements, it can be expensive to return. Our cancellation & returns policy explains this in more detail — see Terms & Conditions.

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.

Please call if you have any questions: +44 (0)1643 703358

Unless a HIAB delivery has been booked at additional cost, it is the customer’s responsibility to offload with suitable equipment on the day of delivery. A failed delivery may result in additional charges.

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.
