Where will you deliver my order to?

Please note that all of our deliveries are kerbside only and it is your responsibility to get it from the Kerb onto your property. It is at the discretion of the courier where the order is left.

Please ensure you have ample space to offload.

Delivery access and site restrictions

We use pallet couriers for these items and they tend to be delivered on large 18T/26T lorries.

A Rigid lorry is approximately 18 / 26 tonnes with the capacity for 12 / 14 pallets. They are usually 10m / 12m Long, 4m high and 2.6m wide as an average.

Please ensure you advise us of any restrictions or access issues you may forsee with this size vehicle, failure to do so may result in extra delivery charges.

When do you dispatch orders?

If your order is placed before 12pm we aim to have these processed and dispatched onto our lorries the next day.

However, sometimes our lorries are already full and booked, so this might be 2 to 5 working days after you place your order. In some scenarios the stock may need to be brought in from another branch which can extend the delivery time up to 10 working days from processing your order. Some areas are also subject to set delivery days due to their distance from the local branch.

Please ensure to leave a mobile number so that we can contact you with your delivery date once we have received confirmation from the local branch. This also allows ourselves or the delivery driver to contact you if there are any issues with your delivery.

Why we need your contact number?

It is essential for us to have your contact number to allow ourselves or the delivery driver to contact you if there is an issue with your delivery.

For orders of this nature we will likely contact you after you have placed the order online to discuss delivery options and any site restrictions or offloading requirements you may have.

Please leave a mobile number as this is normally best for the delivery driver as well.
