## Summary

The Scottish Fire and Rescue Service has completed the procurement process to replace ISDN and PSTN services due to the telecom industry's planned withdrawal of these old analogue services. The contract was awarded to BT, the sole provider of 999 telephony in the UK, ensuring the continuation of essential services such as 999 telephony, corporate telephony, and operational mobilisation through modern digital alternatives based on fibre infrastructure. The procurement method was a limited award procedure without prior publication of a call for competition, with the contract valued at £606,875. The contract was signed on 30th January 2025, and the service's delivery is focused within the UK region, particularly at the service headquarters in Cambuslang, UKM.

This tender presents significant opportunities for businesses specialising in telecommunications, particularly those that provide advanced digital communication solutions customised for critical services like emergency telephony. Companies with expertise in modern fibre infrastructures and who can offer innovative digital alternatives would find this tender beneficial. Moreover, businesses that can increase or adapt services throughout the contract's duration will be favourably positioned to engage with such initiatives. The contract underscores the importance of maintaining high-quality telecommunication services and opens avenues for further growth and collaboration within public safety and telecommunications sectors.
