According to the RICS survey for the first quarter, nearly two-thirds of surveyors warn labour shortages are intensifying despite official construction output data suggesting a cooling in demand.

Just over half warned that tight finance remained an issue while material shortages now appear to have eased.

Surveyors across the country also said contractors were now more choosy, with many avoiding single stage tenders, opening bidder gaps on some regional jobs.

Despite all the anecdotal evidence that a degree of uncertainty is entering the market in the count down to the general election, outward confidence for growth is strong, with 79% of respondents expecting their workloads to rise over the next 12 months and this to translate into 3.8% growth in 2015.

RICS Director of the Built Environment, Alan Muse, said: “Despite the outward optimism, there are some very real unknowns which are impacting on industry, including the general election, the UK’s relationship with Europe and skills shortages.

“Now that material shortages are becoming less of an issue, the practical challenges are in providing the skilled labour the industry needs and in alleviating the financial constraints, which saw nine months of decreased lending in 2014.”
