The awards will see a cut in the number of suppliers from 57 to 20 with four core suppliers providing 70% of the workforce.
All the firms will also be required to pay a minimum of the London living wage and abide by a code of conduct.
Nick Elliott, managing director national supply chain, said: “These new contracts are all about transforming our contingent labour workforce into a more professional, fairly remunerated and appropriately trained body of people that we are able to call upon when the need arises.
“The new code of conduct for labour will drive better employer behaviours, improve the quality of the supply chain and help ensure that workers are treated fairly.
“We believe that investing in this important resource will deliver significant safety and performance benefits for the railway as a whole.”
