Please take a few moments to read the information below as we would like to ensure your delivery takes place as smoothly as possible:

We aim to deliver all tanks within 3-10 working days from order and payment, however some special orders (including steel products) may take longer. If your order is time critical please contact us before ordering so we can confirm delivery dates.

Parts are dispatched within 24 hrs subject to stock availability and please allow 2-3 days for delivery (depending upon location).

For convenience, all single skin and bunded plastic oil tanks up to and including 2500 litres in capacity are delivered on a vehicle with a tail lift to allow easy offloading at the kerbside. Please look for our "Free Tail Lift Offload" icon to confirm which products are included. Unless otherwise agreed by Tanks For Everything (TFE) offloading of all other products are the customer's responsibility.

Delivery will be between 07.30 and 18.30 on the expected delivery day. AM/PM Deliveries are available for some products, however these often incur an additional charge, please contact us for a quote before ordering if you require this option.

All orders will require a signature upon delivery.

FREE delivery includes all of England and Wales mainland destinations, however certain manufacturers charge extra for deliveries to Scotland and the Highlands. Please contact us on 0117 244 4099 for a delivery quote prior to ordering for these locations.

Deliveries of larger products (typically over 2500 litres) require delivery by an articulated vehicle. Please ensure the roads and access point to your delivery address are suitable for a 45ft long high sided articulated vehicle. If access is an issue please arrange delivery to a suitable alternative address where access will not be an issue. The ongoing delivery to the final destination will be your responsibility. If a delivery needs to be aborted, TFE reserves the right to pass on any additional delivery costs, so please if in doubt discuss this with us at time of order.

Whilst every effort will be made to deliver on the expected delivery date, TFE will not accept any charges for labour or compensation claims arising from failed deliveries. TFE strongly recommends that tanks and equipment are ordered in advance of installation allowing sufficient time for any issues to be addressed.

Please remember we are here to help and if we can be of any further assistance at any stage please do not hesitate to contact us on 0117 244 4099.
