Established in 1974, Clarkson is a trusted leader within the UK Fire Safety Industry, proudly maintaining fire alarms and other fire safety systems for over 50 years. Now part of the international DEF Network, we bring global expertise with local commitment.

Our team of directly employed, long-serving engineers operate nationwide 24/7, delivering cost-effective and fully accredited fire maintenance services for our clients. From Fire Alarms and Emergency Lighting to Fire Suppression Systems – we specialise in the design, installation, and maintenance of these critical life safety systems. We also support our clients with various security solutions, including CCTV and Access Control, through our skilled and dedicated regional teams.

With BAFE SP203-1 certification, ISO standards compliance, and our bespoke in-house digital reporting system, we ensure seamless service delivery and transparent communication. By completing maintenance reports in real time whilst on site, this allows us to ensure compliance and record any remedial actions required whilst providing our clients with maintenance reports as soon as the service is complete.

Our unique Emergency Callout triage support service provides our clients with immediate access to technical support, enabling us to resolve over 40% of issues remotely, without the need for a site visit. This approach minimises downtime, reduces disruption, and delivers significant cost savings for our clients – all whilst maintaining the highest levels of safety and compliance.
