If the TER listed on an ETF manager's Key Investor Information Document (KIID) differs from the TER for that ETF listed on the website of a Stock Exchange or broker, it may be that the information listed by the stock exchange is out of date.

A good first step is to contact the ETF manager and ask them to confirm what the TER for the ETF in question is. Consider mentioning the discrepancy so that they can contact the stock exchange to have them update the information.
