A fully outsourced, managed service solution for temporary staff

Engie Regeneration is part of the Engie Group. Their primary focus is home building, neighbourhood refurbishment and property services.

The Engie and Retinue managed service relationship emerged from a strong existing relationship spanning over a 10-year period. In 2016, we were awarded a 3-year contract with the possibility of extending this for a further 2 years.

The contract’s aim was to deliver a fully outsourced temporary staff managed service solution. In this time, we have fulfilled over 5,500 roles with 98% of roles filled first time whilst delivering cost savings in excess of £750k.


  • No cost control or visibility – Using paper-based time recording, Engie had minimal visibility of tracking the volume of workers and associated costs. It was also identified that there were considerable fluctuations around supplier terms& profit margins being charged
  • Inconsistent supplier relationships – Owing to a previous weakness in supply chain management, the relationships with agencies were often strained. Without positive supplier engagement, Engie found themselves receiving an inconsistent service by agencies, which was not measured and quantified
  • High volume of invoices – Engie were found by Retinue to be processing over 20,000 invoices per annum


Our technology platform (VMS365) has allowed Engie to now implement consistent recruitment processes and access real time data – Retinue has facilitated training on VMS365 across the Hiring Manager population.

Hiring Managers are now enabled to complete online requisitions; job approvals; pre vet & select workers; approve time sheets securely on line and receive consolidated invoicing. Available both via desktop and App based technology, VMS365 has provided Engie with real time data on temporary worker usage.

All supplier terms & conditions have been standardised in order to maximise cost efficiencies. Cost savings have included a contractual gain share agreement where both parties are committed to maximising savings for the duration of the contract.

Cashable savings since go live of £758k (including fixed mark-up reductions and fixed NI).

These savings are based on Engie’s current spend of £30.6 million (Since go live date). Due to the success of a robust mandate on process management, 95% of the overall spend was found to have been managed through the contract since the most recent ledger review.

Supply chain rationalisation – Retinue completed an evaluation of Engie’s current suppliers and a gap analysis report was produced based on job title and location.

Completed strategic actions from this report resulted in a more agile & committed supply chain being confirmed. Supplier numbers were reduced from 80 to 42, whilst still supporting Engies’ key challenges and growth ambitions.

Effective P2P processes – Consolidated supplier invoicing by Retinue has reduced invoice volumes needing to be processed from 20,000 per annum to 52 per annum.


"Service is absolutely brilliant, happy with everything. Communication is great between site personnel and the Retinue Account Manager. Raising jobs and approving timesheets is very easy to do. Highly recommend."
