The shake-up will deliver savings of £34m and signs firms up to training 300 apprentices through the life of the deal.

TfL intends to award the five contracts to Engie Services, Interserve Facilities Management, Lanes Group and Vinci Construction UK.

The new contracts, which have a total value of £320m, will last for five years with the option to extend them for a further three.

The suppliers will be responsible for the provision of services and the management of TfL facilities, including fire protection, mechanical and electrical facilities, such as power and water, buildings maintenance, and security and reception services.

A sixth contract, which will be for cleaning, is expected to be awarded in the summer.

David Wylie, Chief Procurement Officer at TfL, said: “We are looking forward to working with our suppliers on these new contracts and by consolidating the existing arrangements, our facilities will be managed in a more efficient and cost-effective way.”
