The number of vacancies for freelancers, contractors and umbrella company contractors has reached a 15 year high, according to a jobs report from KPMG.

Interim workers have not been in such high demand since May of 1998. Along with this is that anyone taking on a temporary job like this is very likely to be paid well. The report says that pay for freelancers and the like is at a 44 month high.

While London was responsible for a large chunk of these new vacancies, it didn’t see the best levels of growth. The North of England has shown the fastest growth in the country, with much of this being traced back to the oil and gas industry.

The Partner and Head of Business Services at KPMG, Bernard Brown, said: “Combine the latest job figures with news that business confidence has reached a new high and it’s easy to share the renewed sense of optimism amongst employers. Permanent placements alone have hit a 4-year peak and with temporary hires accelerating to a 15-year high there is clearly room for corporate investment and, with it, job creation.”

One of the contributing factors to this high is lack of available staff. December 2013 saw the sharpest fall in candidate availability since November 2004. This has also contributed to the increase of pay to temporary workers.
