Vulnerable residents and pensioners are to be charged £150 per year for the Telecare alarm system

The Sunderland City Council operated rapid-response service, which provides an 'invaluable lifeline' to sick and frail residents, is currently free to an estimated 13,000 customers.

But the council, which must find £37m savings over the next financial year, said it has been forced to review the service and introduce the £12.50 a month charge.

The service provides an alarm system for homes linked to a control room in case of an emergency.
