Bills will not be as high as planned for the next financial year, says Yorkshire Water.
It said following concerns about rising household costs it has decided not to push ahead with the planned 2014-15 price increase agreed with industry regulator Ofwat.
That means the average household bill will be in line with the current rate of inflation, with the average bill being £373 - £6 lower than planned.
Yorkshire Water also said it would publish plans on Monday to keep bills at this lower level from 2015-2020.
Chief executive Richard Flint, said: “Over the last 18 months, we have listened to the views of more than 30,000 customers to help shape where we invest over the next five years, and how that will impact on customer bills.
“Yorkshire Water bills are already lower the national average but we are committed to doing even more to help our customers.
“We understand the pressures on households and that’s why we’re planning to keep bills in line with inflation for the next six years.
“This is a challenging plan that we are confident we’ll deliver through prudent financial management, sharing company efficiencies with customers and by reducing our returns to investors.”
The company is also planning to invest £3.8 billion between 2015 and 2020.
That includes improving river quality in Halifax and Leeds where £31m is planned to reduce the impact of storm water discharges into rivers.
More will be spent on sewage treatment works to reduce the nutrients passing through to water courses in the Calder and Aire valleys.
And across the region £14 million will be spent on storm tanks which will help to minimise the risk of flooding from sewers at times of heavy rainfall.
