The growth in managed services has been gatering momentum over the last couple of years benefitting resellers as well as dedicated outsourcing players.
Figures from a report commissioned by the Business Services Association indicate that outsourcing is now generating more than £200bn.
There are 340,000 people working in outsourcing and it contributes £27.4bn to the coffers.
Bindi Bhullar, director of HCL Technologies, said that for too long the growth of outsourcing had been overlooked and the research showed it had now developed into a mature market.
"Thanks to this maturity, organisations now have access to new talent, advanced technologies that can deliver additional benefits, and most notably, faster time to market for new applications and upgrades alike," added Bhullar.
