IT experts are the most sought after professionals within Greater London, accounting for 28.4% of all vacancies in the 24-month period to May 2017, according to data from the Association of Professional Staffing Companies and Vacancysoft.

The data from APSCO and Vacancysoft includes jobs announced by 3,145 employers. It showed that across the board there was a 10% rise in vacancy volume in the three months to May 2017 compared to the previous three months and 2.6% more than the same period in 2016.

The Marketing and PR sector experienced the biggest growth in terms of number of vacancies and the fastest growth of any of the major professions. There were 5.2% more new jobs than the previous 12 months in the period ending 31 May 2017.  Demand came mainly from the Technology, Media & Telecoms sector, which advertised 12.4% more openings for Marketing and PR staff. The insurance sector recorded a 22.2% rise in demand compared to the previous 12 months.

Professional services firms announced fewer vacancies over the 12-month period ending in May; this led to a fall in the number of accountancy representing a 9.6% decrease in demand.

The public sector saw the largest growth in roles with a 5.8% increase over the 12-month period ending in May. The education sector in particular saw a 19% increase over the year.

“Greater London continues to be a remarkably diverse employment market with no more than one single employer accounting for more than 2.6% of vacancies,” Ann Swain, chief executive of APSCo, said.

“Our statistics also show is that the greatest growth in demand actually came from medium sized companies (101-200 ranked), advertising nearly 10% (9.4%) more vacancies during the year,” Swain said.
