ESG: Thames Water puts its money where its mouth is

In early December, UK water utility Thames Water became the first UK corporate to tie the interest rate it will pay on a revolving credit facility (RCF) to its score under the Global Real Estate Sustainability Benchmark (GRESB) for infrastructure.

The £1.4 billion revolver was arranged by BNP Paribas and runs until 2023 with the option of a two-year extension. If the firm outperforms its GRESB infrastructure score, the margin that it pays will be lowered and any financial gains put towards Thames Water’s charitable fund.

Tom Bolton, head of corporate finance at Thames Water, tells Euromoney that the firm is responding to investor demand.
