This impacts case study shows how our investigation of a contract in which Defra appeared to have been overcharged gave greater impetus and legitimacy to Defra’s approach to negotiating a settlement.

It is one example of financial or non-financial benefits realised in 2014 as a result of our involvement, all of which are set out in our interactive PDF.

Impacts case study

In 2014, we conducted an investigation into the Department for Environment, Food & Rural Affairs’ (Defra) Interserve facilities management contract. We examined the issues arising from the contract and reviewed Defra’s work to assure itself it understood the extent of these issues, including amounts that it could have potentially been overcharged.

What are impacts?

Our findings were considered fully by Defra as part of their final calculations. Defra told us “whilst we were already considering an amount of settlement, the NAO investigation report gave greater impetus to the work being conducted at a very senior level within core Defra. It also provided independent validation that the methodology and approach the department was adopting in seeking a settlement was legitimate.
