The number of IT jobs increased 18% year-on-year in Q2, according to research from specialist IT recruitment website CWJobs.co.uk.

The research shows London now makes up 33% of all UK IT jobs advertised with over 37,000 London-based IT jobs advertised in the second quarter of 2011 alone, with developer roles now making up 39% of all jobs advertised in the UK.

Q2 2011 marked eight consecutive quarters of increasing demand for IT jobseekers.

Richard Nott, website director at CWJobs, says: “It’s promising to see that the government’s investment in the IT sector is being reflected in the recruitment market.”
