Company network of fire safety experts


Since being founded in 1974,  Clarkson became experts in the maintenance of fire safety systems in the UK working predominantly within the food retail sector.  Our most valued endorsement is that we installed a fire alarm system in a London Sainsbury’s store in 1974 and have maintained the fire alarm systems across the full Sainsbury’s estate with circa 1500 sites ever since.

In 2006, Clarkson was awarded third party accreditation with BAFE, obtaining the SP203-1 certification for the design, installation, commissioning & maintenance of fire detection and fire alarm systems. BAFE is operated by UKAS and each company holding the BAFE mark is audited annually to ensure compliance. Further information can be found at

In August 2013, Clarkson was acquired by DEF, an independent fire systems manufacturer and service provider from Paris, France. In 2014, Clarkson joined the DEF Network, a company network of fire technology experts covering 30 countries from Europe, Africa and Asia.

More recently, Clarkson has invested into paperless engineer reporting through our service order management system application called data driven. Data driven interfaces seamlessly with Clarkson’s CRM system, Microsoft Navision and allows reports to be completed by engineers on tablets and processed, reviewed and then emailed to our clients along with any remedial actions required at the swipe of a screen.
