But latest data from Mace Business School shows fewer companies are predicting  increases in lead times over the next six months compared to previous surveys.

Mace said: “The industry continues to be busy but there are signs that most companies are resourcing to provide the capacity to cope with the current increase.

“Fewer companies are also forecasting increases in lead times over the next six months compared to last quarter forecasts.

“Brickwork and blockwork lead times continue to increase due a combination of shortages of transportation and manufacturing capacity issues.

“The typical four week lead time for brickwork has increased to 11 weeks, the highest level since our records began in 1999. The previous high of 10 weeks was back in 2007/8.

“The lead time for Blockwork has gradually grown over the past 25 years but at 7 weeks has not come close to the peak of 10 weeks in 2007. ”
