Important Delivery Information

We offer convenient home and site delivery to get your materials exactly where you need them. If you have any special requirements, please leave a note in the customer notes at checkout. To ensure a safe and successful delivery by our crane lorry or pallet truck, please note the following access requirements:

• Firm & Level Surface Required: Our delivery equipment (pallet trucks and crane lorries) can only operate on a firm, level, and paved surface such as concrete, block paving, or tarmac.

• Surface Restrictions: We cannot offload onto soft, uneven surfaces like grass, gravel, or soil, nor can we maneuver on steep slopes. Delivery is always subject to the driver’s professional discretion regarding safety.

• Kerbside Policy: If we are unable to access your preferred site area due to restricted access or unsuitable ground, your pallet will be safely left at the kerbside. It will then be your responsibility to move the product to your final location.

• Vehicle Access: Our delivery vehicles are large (similar in size to a refuse lorry). If you anticipate any access issues on the roads leading to your property, please inform us before placing your order so we can make alternative arrangements.

• Difficult to find?: If your property is notoriously difficult to find please use what3words and provide in customer notes at checkout.
