Thames Water has proposed adding up to £3 billion more to its spending plans for PR24, bringing its total expenditure to £21.7 billion for the five years to 2030. This would raise household bills by a further £19 to £627 by 2030, if the full £3 billion of proposed spending goes ahead. It also takes the industry's total spending ask for PR24 to just over £100 billion, with all other companies already announcing updates to their business plans.
