Thames Water lost almost two-thirds of its value last year as the struggling utility group came close to collapsing under the weight of its debts, figures from its second-largest shareholder show.

Church Water Investment, which holds 20% of Thames’ parent company Kemble Water Holdings, wrote down the value of the stake by 62%, according to annual accounts to March 2023. The numbers were released on Saturday.
