Key Facts

Project Synopsis

TSS provided a wide range of professional services to Amey for its utilities, facilities management and local government divisions, on numerous contracts across the UK.

Amey’s Utilities Division undertook construction and refurbishment / rebuilding of 11kv, 33kv, 66kv light & heavy construction overhead lines across for Western Power Distribution (WPD) across all four WPD geographic regions.

We were initially brought in by Amey to review and improve commercial, planning and contract management of the WPD contract to ensure good governance was in place. Acting as interim manager within the contract team, we identified risks and opportunities in the financial, operational systems and practices.

Following the initial review, Amey asked us to bring in a 7-strong team of commercial specialists. We implemented robust, uniform systems and processes. We transformed the management approach, generating significant savings, working capital improvement and ensuring sustainable, consistent contract performance.

Scope of Works 

The TSS team implement

  • Work order management system for projects & orders, giving one version of the truth
  • Weekly & monthly review meetings for contract and project performance
  • Reporting and dashboards
  • Commercial management best practice on live sites
  • Work bank analysis

We re-procured the supply chain via a competitive tender process.

Overcoming Challenges

A disputed supplier account valued at £1.36m was unresolved. TSS facilitated a fresh start to assess the claim, backed by our RICS standing.

Our in-depth review provided the necessary substantiation and diligence. We resolved the dispute through investigation, negotiation and a facts-based approach.


• Supply chain re-procurement generated £980k pa savings
• Improved end-to-end governance processes reduced WIP by £3.5m over 12 months.
• WPD satisfaction improved – invoice disputes reduced to nil and debtors reduced by an average of £560k


TSS have worked within Amey since 2012, delivering both commercial and project management services across our regulated sector UK wide contracts. Our long-standing relationship has been built on the confidence we have in TSS’s clear communication on cost, governance, contract performance, and stakeholder engagement. Often having to deliver consistent messages across internal and external commercial horizons, TSS are a trusted partner in our more challenging environments.
