bags of cement in a house under construction Supplies of bagged cement and certain electronic components are “growing areas of concern”, the Construction Leadership Council has said. The CLC said in its latest update that product availability is worsening, as it previously warned was likely to happen. Supplies are likely to face constraints for the next six months due to strong national and global demand. Activity in the UK has increased since March, it added, with the previously subdued commercial and industrial sectors seeing workloads pick up. A shortage of haulage drivers and increased demand from the consumer-goods sector is also making it harder to find transportation for items, the CLC said.
