Families have already had to contend with high energy bills and soaring petrol costs in recent months.
And now it seems finances are set to become even further stretched, as Ofwat has revealed that water and sewerage bills are due to go up.
The regulator said that from this April, people's annual bills could rise by roughly £20, with the average bill due to hit £376.
However, the regulator added that in the longer term, bills should remain broadly in line with the UK's rate of inflation. It said this should be the case by 2015, as a result of a challenge it mounted in face of proposed bill hikes.
Regina Finn, chief executive officer at Ofwat, said the views of customers were taken into account when price limits were set.
She added: "They told us they wanted bills kept down, while maintaining safe, reliable water supplies. We challenged companies hard to deliver this.
"Our decision meant that, before inflation, average bills would remain broadly stable between 2010-15."
Action will be taken against any firm that fails to meet its investment promises, Ms Finn emphasised.
