Barnsley residents who use the Careline service, which offers residents 24-hour access to help if they press a buzzer around their neck, will have to start paying for the service from April.
It had been provided free of charge by Barnsley Council but because of Government Supporting People funding stopping, users will now be charged for the service.
Around 1,300 residents are set to be affected by the changes.
Councillor Jenny Platts, Barnsley Council’s cabinet spokesperson for Adults and Communities, said: “We are extremely proud that we are able to offer a service that is so well thought of and valued by so many service users, their families and carers.
“I would urge anyone who we’ve not yet been able to reach to contact us by calling 01226 787726 or 787783.”
