Residential retrofit program: apply for a low-flush toilet credit


This program is for residential customers who receive water services from Utilities Kingston. Commercial customers can visit our toilet replacement rebate page.

To help customers reduce water and sewer use, Utilities Kingston is offering a $30 bill credit on the purchase and installation of low-flush toilets to residential water customers. Customers can upgrade every eligible toilet in their home.

How it works

  • You must receive residential water services from Utilities Kingston. 
  • This program is for low-flush toilets purchased and installed on or after August 2, 2022.
  • Buy and install a low-flush toilet (maximum of 4.8 litres per flush), to retrofit an existing low-efficiency toilet.
  • Complete the online application and send proof of payment to Utilities Kingston.
  • If you are eligible, Utilities Kingston will apply a credit of $30 to your utility account, for each toilet you upgrade in your home.
  • Funding is limited and eligible applications will be awarded on a first-come, first-served basis.

Subject to additional terms and conditions.

Our program manager will review all applications as they are received, and will follow up if additional clarification is required. If you don’t hear from us, no news is good news, and we will apply the credit to your account. Depending on your billing cycle, the credit will appear on your next bill, or the subsequent one.
