CST Awarded Royal Warrant
By Royal Appointment: Call Systems Technology Limited
We are delighted to share some very special news. On 22nd April 2025, Call Systems Technology Limited was officially granted a Royal Warrant of Appointment by His Majesty King Charles III.
This prestigious recognition marks a major milestone in our company’s journey from our beginnings as a family-run business in the early 1990s to becoming a trusted national supplier of RF wireless communication and critical alert systems. To now be named among the select group of companies recognised by the Royal Household is an honour that speaks to our ongoing dedication, consistency and commitment to excellence.
A Royal Warrant is far more than a mark of prestige. It is a symbol of trust, one that cannot be bought or granted through sponsorship. It is a privilege awarded only to companies who have supplied goods or services to the Royal Household over several years and who meet the highest standards of quality, service and integrity.
