Before you order concrete blocks

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.

Thickness

100 mm is the common inner-leaf thickness. Wider blocks (140, 190, 215 mm) are used for separating walls, single-skin garage walls and foundations.

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.

How delivery works in Leigh

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. Leigh is inside our standard mainland delivery area.

• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• Give us the full postcode for the drop point; deliveries around WN7 are priced to the exact address.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
