The secure choice for fire safety

Sentry Fire Safety Group is a specialist manufacturer of timber fire and security doorsets for the social housing, public sector, commercial and residential markets. Operating nationally from two manufacturing facilities in Doncaster and Birmingham, Sentry Fire Safety Group has established a strong reputation for manufacturing products that meet the most rigorous quality and fire certification standards. Our wide range of customers focus primarily on Repair Maintenance and Improvement and operate across the built environment.
As the UK leading manufacturer of timber fire safety doorset manufacturing, Sentry Fire Safety Group enjoys a significant reputation throughout the passive fire safety protection sector. It achieves this status both through its size and through its commitment to professionalisation, leading the way in ensuring comprehensive compliance with established and emerging fire safety standards and actively contributing to the highest standards of construction practice.


Leading certif­ication, reflecting regulatory compliance

Sentry’s extensive certification portfolio includes primary independent testing via BM Trada and Certifire; Secured by Design certification and one of the few companies nationally to have achieved Q-Mark dual certification for its flat entrance door sets. Sentry Fire Safety Group was also the first UK organisation to be accredited to the new UKCA standards. We also embrace the need to positively contribute to the Golden Thread – guidance which ensures that installation and maintenance records are transparently available for end-users and inspectors, through its simple, effective door tagging solution powered by Door Data Systems.

Sentry Fire Safety Group, therefore, offers a powerful partnership for those implementing the Fire Safety Regulations which came into force in January 2023. It also continually invests in its product development and compliance to reflect emerging regulatory demands.

In short, Sentry Fire Safety Group offers a comprehensive field of application across its markets – from commercial buildings to social housing, student accommodation to healthcare settings.


Invest­ment and expansion

Our investor, Cairngorm Capital, backed the expansion of Sentry Fire Safety Group into additional markets through the acquisition of 100-year-old E & S W Knowles company in 2022. This ensured the provision of veneered and lacquered doorsets into complementary markets such as student accommodation and healthcare. Knowles is now integrated into the Group and its range incorporated within our extensive catalogue.

We have continued to invest in Sentry Fire Safety Group to ensure that the company is well equipped to respond to regulatory change and increased market demand, substantially expanding manufacturing capacity and extending geographic distribution.


Sustain­ability and social value

Timber has the lowest embodied carbon footprint of any building material, but Sentry Fire Safety Group also holds FSC accreditation, meaning that all our materials are renewed. This is one element of an extensive Environmental Social Governance programme with commitments to providing secure, local employment in a safe environment and to charities that reflect our values.
