It may seem like a while ago, but there was a fiery exchange last month at the Environment, Food and Rural Affairs Committee as Sir Adrian Montague, the chair of Thames Water, defended the bonus scheme for the company's senior executives.
Sir Adrian told the committee that creditors had insisted on bonuses being paid - something he later confirmed was not the case.
He claimed to have "misspoken", and that it was instead part of a strategy to prevent upheaval at the top of Thames Water.
A letter Sir Alan sent to the EFRA committee has now been published, which gives more details on the bonus agreement.
The bonuses worked out to: "50% of base salary on 30 April 2025; 50% on completion of [Thames Water's] second restructuring plan or, if earlier, December 2025; and a final payment of 200% of base salary in June 2026."
Sir Alan said that he himself, as well as CEO Chris Weston, or CFO Steve Buck, did not get a payout.
The 30 April payment has been meted out already, and the board of Thames Water "does not intend to recover this money".
Any further bonuses have been paused.
EFRA Committee chair Alistair Carmichael MP said bonuses for water company CEOs and CFOs were banned last year - and wants to know if the government will take action on the latest revelation.
He said: "We are also asking whether Defra and Ofwat were aware of these payments and what undertakings they have received from Thames Water about the pausing or withdrawal of the retention plan.
"Given that the plan includes two further retention payments, including 200% of base salary due to be paid to these 21 individuals in June 2026, it is vital that Thames Water, Defra and Ofwat are clear with us all about what exactly is going on."
Sky News understands the government is not planning to try to recoup the money.
