How quickly do the out-of-hours call centre respond? Lench's Trust works with an emergency call centre called Connexus. Connexus offers a 24 hour service, which is not only provided on weekends but also anytime the Scheme Manager is off duty, be it due to the end of his/her shift or because he/she has a training day or other commitments. As a results, there is consequently always cover provided. Once someone has pulled the alarm call cord the call is answered promptly and the necessary procedures are taken.
