Waking watch costs are crippling leaseholders across the UK. We compare the options and explain how BS 8629 alarm systems can provide equivalent safety at a fraction of the cost.. The Waking Watch Crisis Waking watch patrols — where personnel patrol buildings 24/7 to detect fires — cost between £15,000 and £40,000 per month per building. Some buildings have been paying for 5+ years. BS 8629: The Alternative BS 8629:2019 provides a code of practice for the installation of evacuation alert systems. These purpose designed systems can replace waking watches at significantly lower cost.
