Households on the Isle of Wight will see their Southern Water bills rise again from April, with the average combined water and wastewater bill increasing by eight per cent. The increase comes a year after customers faced a much steeper jump in charges, when average bills rose by almost 47 per cent. Southern Water says the latest rise is part of a longer-term plan to spread further increases more gradually. Southern Water insists all revenue from the price rise will be reinvested into services rather than paid out to shareholders. Households receiving water-only services will see an average increase of 25.8 per cent, while those receiving wastewater-only services are expected to see bills fall by around four per cent.
