The data were released as a survey by another IT company, Modis, suggested that nine out of 10 IT leaders believe their "internal reputation lags behind their actual contribution."
According to Virgin’s survey, the most frustrated IT workers are in London, where three quarters say they have not been able to change the way the IT department is perceived by the rest of the organisation.
Modis’ poll found that just 7% of IT workers believe their area is deemed an invaluable service to the business.
However, half of respondents to Modis also said that IT was becoming more involved in "managing major change within their organisations" although a third felt that their companies saw IT workers as "implementers of pre-determined decisions."
Jim Albert MD at Modis, said: "IT still needs to deliver its traditional functions but at the same time company boards are asking ever more of their IT leaders, placing more responsibility on their shoulders for overall business development.
"This trend is in many ways a positive step for the industry but it is by no means universal, with many IT teams still burdened by a belief that they are just there to carry out transactional activity."
Virgin Media Business’ executive director, commercial, Andrew McGrath, said: "IT departments remain the unsung heroes of many organisations.
"The good news is that advances in technology, such as cloud computing, are really starting to help unburden IT managers from the small tasks that can hold back innovation, enabling them to focus on the bigger picture."
This week, consultants Deloitte launched a competition asking university students to submit ideas on how technological problems can solve business problems.
The Top Technology Talent Competition is in its second year and awards a prize of either £1,000 or four weeks paid work experience at Deloitte’s technology integration practice.
Last year’s winner was Moonwon Lee from Trinity College, Dublin.
The Department for Business Innovation and Skills have also invited organisations to register their in forming a technology and innovation centre focused on high value manufacturing.
The centre will be the first of an national network of centres, to be established and overseen by the Technology Strategy Board, that will work in partnership with universities and businesses to help commercialise the results of research in specific technology areas where there are potential multi-billion pound global markets.
Deputy Prime Minister Nick Clegg said: "We should be at the cutting edge of science, manufacturing and technology. The programme for technology and innovation centres is a key part of our strategy to rebalance the economy."
