Important — please read
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.
