Supporting Safer Communities

As part of Astraseal’s ongoing commitment to social value, we are proud to partner with the JE3 Foundation to help improve access to life-saving equipment in the communities we serve. For every new client or council we work with, Astraseal will be donating a defibrillator to be installed at a location of their choice, helping to strengthen local emergency response and public safety. Through this initiative, communities at Icknield Walk in Royston and Girton Court in Hitchin now have access to new defibrillators, installed by Settle in partnership with the JE3 Foundation which ensures vital equipment is available where it is needed most.
