The simple answer is no, as everything is included in your plan. We do not charge you any extra if you activate your alarm.
The following information may be helpful concerning call costs:
If you press your pendant, the careline alarm will contact our control centre using an 0844 number via your telephone line. These numbers are recommended by OFCOM for contacting organisations such as Careline24.  Your telephone service provider may charge you for these calls. Please check your phone providers tariff or visit OFCOM for further details. We do not apply any levy on these call costs.
