IT professionals specialising in big data are benefiting from growth in pay as employers show more demand for their skills, research has revealed.

In its latest Tech Cities Job Watch report, IT resourcing firm Experis revealed that average salaries for people with big data expertise have risen by almost eight per cent in a year.

That's nearly three per cent higher than the Bank of England's projected three per cent pay increase for the whole of Britain.

Experis' research is based on over 60,500 jobs advertised across five key tech disciplines: big data, cloud, IT security, mobile and web development.

The latest figures showed 5,148 big data jobs available in the first quarter of 2016, 87 per cent of which were based in London.

One of the key factors in the recent growth in this sector is the rising importance of personal data for businesses that want to improve their customer understanding and predict forthcoming trends.

Many companies are also bringing big data and compliance skills in-house to ensure they stay in line with new EU data protection regulations.

Geoff Smith, managing director at Experis, said big data will continue to be a "major driver" of UK economic growth as the digital revolution gathers pace.

"Yet, many companies have been slow to react and there's a limited talent pool to choose from," he added.

"Employers are willing to pay highly competitive salaries to attract these experts, so they can help with compliance, uncover valuable customer insights that can transform their business and innovate for the future."

Big data and the Internet of Things are set to add £322 billion to the UK economy within the next four years, according to a recent report from the Centre for Economics and Business Research and software provider SAS.
