Delivery

Delivery costs for your order will be calculated during the checkout process based on your delivery address and the contents of your basket. You will only pay one delivery charge for your order. Express delivery is FREE for online orders OVER £39 unless any of the points below become a factor.

  • Some large items like aquariums, ponds and pond liners will have an additional charge of £45.00 to help offset the cost of a pallet delivery.
  • Orders containing a physical gift card will have an additional charge of £2.45 to cover the cost of materials and delivery (digital gift cards are a free alternative).
  • Orders to highlands, islands and Northern Ireland may incur an additional delivery charge displayed at checkout this is based on the postal code provided. DPD provides a list of postal codes which have additional surcharges. Some of these post codes may also take 2 working days to arrive, even on express. Pallet deliveries cannot be sent to these post codes.

We only ship to the UK and cannot ship internationally.

We aim to dispatch items that are currently in stock on the same working day if they are ordered before 2.45 pm (excluding Bank Holidays). Orders after 3pm will be dispatched the following working day, unless it fits any of the below criteria:

  • Orders containing live plants will take up to 2 weeks to arrive. We take a week's worth of customer orders and then inform the plant farms of the specific quantities we need to fulfil that week's order to avoid wastage.
  • Pallet orders containing large items like big aquariums will take additional time to arrive as they are sent by a third party. These orders will NOT be dispatched until we have been in touch to arrange a delivery date, this is to ensure someone is available at your address to sign for the delivery. Deliveries will generally be delivered ‘curb side’ within the terms of the agreement we have with our couriers so you will need to make arrangements to transfer larger items into your home yourself. Unfortunately, our drivers are not insured to transfer the aquarium into your home.
