Commissioning
*Please note that additional commissioning costs may apply for certain Scottish Postcodes. These charges reflect the additional logistics required for servicing these areas. To confirm if your location incurs additional fees, please contact our customer service team for further information.

Delivery
All our Clearwater tanks are for delivery by customer offload. This entails the customer to acquire the right manpower and/or machinery to help unload the tank/s from the delivery vehicle.
If you require assistance with offloading, we may be able to offer a tail lift (lowers the tank to the ground) or HIAB (lorry with a mounted crane to winch the tank off to the nearest hardstanding area only, at an additional cost). Please contact us if this is required for delivery.

To ensure your system operates to maximum efficiency, we recommend tried and tested Commissioning by our own British Water and Safe Building trained engineers.
Our unrivalled knowledge means that we are best placed to carry out bespoke assessments to get your system up and running. The commissioning will also provide you with a unique checklist against your system, ensuring your complete peace of mind and reassurance that your system's mechanical and electrical components are in good working order.
The checks below will be carried out by a Kingspan Service Engineer and will only be checked if the unit has been installed in line with the provided installation guidelines.
- Check Plant is level, 5 mm tolerance
- Confirm the ground around the plant is level, flat and that the lid securely fastens
- Confirm the panel has been mounted correctly
- Make the required connections to the panel using correct glands
- Make all electrical connections within the tank
- Ensure all safety guards are fitted

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.

Offloading
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.
