We offer delivery to most of the country except to Northern Ireland and islands, not connected to the mainland by a physical road. 

While we make every effort to ensure orders are delivered on time, we cannot guarantee availability due to the haulage company’s delivery schedules. Once the order has been placed, a member of staff will then be in contact to confirm a delivery date. Bricks can be delivered to any part of the country except Northern Ireland and all islands not connected to the mainland by roads.

Please be aware, most of the orders are sent on articulated lorries which are large trucks, if the delivery address is not easily accessible, and a rigid lorry (similar to builders merchant lorries in size) is required, we have to be notified. It may increase the waiting time.

For combined brick, special shape, brick slip and/or creasing tile delivery quote, please contact our sales team on

Delivery to Zone 1 - 3 postcodes:

• Orders of 4 packs or less are delivered on a tail lift lorry and offloaded using a manual pump truck, kerbside delivery. Please note, to unload and move bricks around on a pump truck, a flat concrete road surface is required, these lorries can not be unloaded whilst on a slope, the pump truck cannot be used on grass, soft road surfaces and gravel roads.
• Orders of 5 packs or more will usually be delivered on an articulated crane off-load vehicle unless particularly difficult to access. Please see exclusions below in “where do you deliver” section. If a smaller, rigid size lorry is required, please contact our sales team to discuss.

Delivery to Zone 4 postcodes:

• Any quantity and size orders will be delivered on a tail lift lorry. If you require a crane offload vehicle, please get in touch prior to ordering, as crane offload vehicles are priced differently to these areas as well as the lead time might be longer.
