WaterHelp and WaterSure

If you’re finding it hard to pay your bills, we want to do all that we can to help.

We’ve designed our WaterSure bill cap and WaterHelp schemes to lighten the load on households in need of extra support. This includes:

  • low-income households
  • households whose water bill takes up a large proportion of their household income

  • households with large families

  • those who have a water-dependent medical condition

What’s WaterHelp?

We may be able to discount your bill through WaterHelp, if either:

  • your total household income is below £17,005, or below £21,749 in London boroughs
  • your water bill is more than 5% of your net income, taking into account the number of occupants

If you qualify, we currently offer a 50% discount on your whole bill. This amount may change in the future.

In order to qualify, we’ll need to check your details and verify your income.

What’s WaterSure bill cap?

If you’re on a water meter but finding it hard to save water because you have a large family or water-dependent medical condition, we may be able to cap your bills through WaterSure.

We always use the average price based on what other customers pay. For this year (2023/24), for example, we’d cap your bills at £456. If you already use less, you’ll keep paying less.

To qualify for the scheme, someone in your household:

  • Must receive a means-tested benefit (see full list below) AND
  • Must have a medical condition that requires extra water OR
  • Three or more children under the age of 19 living at the property making you eligible for child benefits
