We have three SupportPlus tariffs available, and they may be able to reduce your bill by up to 50%.

These tariffs are perfect for you, if:

  • your total household income is less than £16,480, and your annual water bill is more than 3% of your net household income (after housing costs, rent or mortgage payments)
  • a member of your household receives Pension Credit, and your annual water bill is 3% or more of your net household income (after housing costs, rent or mortgage payments), or
  • your income is not enough to cover your essential bills - in this case, you'll need a financial assessment from an independent debt advice organisation, such as StepChange Debt Charity, along with your application.


Your total household income includes your benefits, such as universal credit and housing benefit, but does not include disability benefits such as Disability Living Allowance, Personal Independence Payments Attendance Allowance and other disability payments.

How to work out your bill percentage

To work out your bill percentage, take your annual bill amount and divide it by your annual income (after tax), then multiply this number by 100.


Here are some examples:

We're happy to calculate this figure for you if it helps. So we can do this, please email us at supportplus@nwl.co.uk with your customer account number, income information and housing amounts for us to check for you.
