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.
