A growing shortage of building workers, including bricklayers and carpenters, is holding back firms as they struggle to keep up with demand for new housing and infrastructure, according to a report.
More expensive building materials is also affecting companies, which expect costs to rise by 10% over the next year, said the Royal Institution of Chartered Surveyors (RICS).
Its survey of more than 500 chartered surveyors showed growing workloads in the industry, especially for housing and energy projects.
Firms in the construction supply chain struggled to keep up with demand amid a shortage of staff to deliver projects, said RICS.
Respondents said the construction sector is now broadly recovering well from the Covid-19 pandemic, but concerns were raised about labour shortages, both for skilled labour and white-collar jobs.
The outlook for profits improved slightly for a second successive quarter in the three months to June following nine consecutive quarters of negative expectations, said RICS.
Chief economist Simon Rubinsohn said: “The tone to much of the feedback is pretty upbeat with new business inquiries picking up smartly and this being reflected in the expectation that workloads will continue to grow strongly over the next year.
“Infrastructure and private housebuilding are viewed as likely to remain the most buoyant areas of the industry.
“Yet it is abundantly clear that a couple of issues present big challenges. Most notably at this point, the availability of building materials stands out as a key problem.
“Almost as significantly, labour and skills are increasingly being cited as obstacles for businesses looking to build out existing commitments or embark on new projects.
“For the time being, the issue appears most visible regarding skilled trades but quantity surveyors are also being highlighted as an area of growing shortage.
A Government spokesman said: “Right across the country we’re supporting employers to fill vacancies in a range of industries including construction by highlighting opportunities available through our nationwide network of Jobcentres and Job Help site.
“Whether it’s on our sector-based Work Academy Programme, Kickstart Scheme or our expanded apprenticeship and traineeship offers, we’re helping jobseekers build the skills and experience needed to take up these opportunities.”
