What is the heatAlert Sussex service?

heatAlert is a FREE service provided by the Sussex Air Quality Partnership (Sussex-air) and is supported by the Public Health Bodies (East Sussex and West Sussex County Councils). The service is operational between June and September, providing free “heatwave warnings”, particularly for those with respiratory and cardiovascular conditions, vulnerable residents, parents of young children, carers and healthcare professionals across Sussex.

The heatAlert service provides:

  • FREE heatwave alerts direct to you and/or your carer or health professional
