Things to check before you order

Handling heavy blocks

Health and safety guidance discourages laying very heavy blocks by hand for long periods. Lighter blocks or planning the lift can make a big difference on site.

What strength do I need?

Most houses use 3.6 N/mm² or 7.3 N/mm² blocks. Your structural design, your building control officer or the block manufacturer's guidance sets the grade; tell us what is specified and we will match it.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Delivery to Sale: what helps

Blocks are banded on pallets and usually crane-offloaded where the vehicle and access allow; tell us the weight limit of any drive or the ground where pallets will sit. Sale is inside our standard mainland delivery area.

• If neighbours share the access, it helps to let them know a lorry is coming.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
