Our History
1963
Laying the foundations for over six decades of business growth.
Thermocable Flexible Elements Limited was founded in 1963, first trading as Thermo-Insulations (Yorkshire) Limited and changed its name to Thermocable (Flexible Elements) Limited in 1978, moving to our current premises at Pasture Lane, Clayton, Bradford in 1980.
Here the foundations were laid to provide longevity as a successful trading entity with a rich heritage of product development and innovation.
1980’s
Harnessing our home-grown engineering expertise.
Equipment designed and engineered in-house, delivered the capability to produce heating cables with market leading flexibility, the key requirement for long-lasting electric blankets. As time progressed the manufacture of flexible heating cables became Thermocable’s core competence.
Harnessing this considerable in-house expertise led to our association with the innovation, design, and manufacture of these cables as demand continued to grow.
1990’s-2002
Gearing up to export our flexible heating cables.
Thermocable began to export flexible heating cables to electric blanket manufacturers in Europe, South Africa, and Hong Kong in the late 1990’s, and in 2001 acquired an additional facility to manage increasing demands on the business, especially with the anticipation of exporting heating cables to the USA.
As new markets were being established, it became clear that increased globalisation combined with manufacturers moving production facilities overseas, would lead to the demise of manufacturing electric blankets in the UK.
2003-2011
Signalling an intensive period of R&D and launching linear detection.
The business began an intensive research and development programme to identify new cables that could be developed and manufactured from existing technologies and to diversify and penetrate new and more robust markets. The outcome: a suite of linear detection products developed and qualified to international product approvals.
2011-2022
Enhancing our family of linear detection products and growing the ProReact brand.
We have subsequently safeguarded our product innovations and approvals with the appropriate patents and trademarks. This has been followed by vertically integrating our supply chain to increase control over product quality and availability. Our manufacturing facility is now state of the art and contains a purpose-built testing laboratory to measure consistency in the goods produced and to further strengthen our product development capabilities.
Thermocable continues to raise the bar by launching new products to the marketplace based on internal R&D and customer feedback - our ProReact brand has accumulated quick traction in the industry and is now widely recognised across the globe as a leading brand name in linear heat detection.
2023
Becoming a Halma company.
Recognised as a leading developer and manufacturer of Linear Heat Detectors, with continued scope for expansion, Thermocable were delighted to join Halma’s global group of life-saving technology companies in February 2023.
“Thermocable’s specialist technologies will further enhance Apollo’s existing strengths in fire detection and alarm systems for industrial and commercial customers,” said Andrew Williams, Group Chief Executive of Halma. “They will enable Apollo to address a greater range of customer needs in niche applications for a variety of sectors such as urban infrastructure and transportation, logistics, natural resources and emerging applications in renewable power generation.”
2025
Expanding into pastures new…
Continuing to grow and develop rapidly, Thermocable upped sticks and moved our HQ, factory, and stores to the 39,435sq ft facility at Leftfield Park in Bradford. Alice Ham, general manager, said: “We are so proud of how much we have grown over the last couple of years, and taking this next step in our journey is a huge milestone…“This office and warehouse space will enable us to continue with our ten-year growth plan without the need to scrimp on space or worry about new equipment and recruitment.
“We are excited to continue to boost Bradford’s economy, bridge industry skills gaps, and continue to raise the bar in manufacturing excellence and fire safety.”
Looking to the future
A focus on delivering major benefits to our customers.
Backed by Halma, the team at Thermocable continues to grow through the recruitment of skilled and experienced individuals whose contribution will support the next phase of our international sales and product development.
