What Flint Engineering does
Flint Engineering Ltd is a UK-based private energy management company founded in 2012 and headquartered in Mayfield, East Sussex. It develops and commercializes the patented IsoMat™ Isothermal Energy Management System (EMS™), a phase-change thermal management platform that absorbs and releases thermal energy to regulate temperature across multiple applications. The company operates with 1–10 employees and is founder/management owned.
The company's portfolio consists of four product lines built on the same underlying IsoMat™ technology: IsoMat™ Commercial Refrigeration Shelving for energy management in retail and commercial cold-chain environments; IsoMat™ EV Battery Pack / Battery Cooling Plate for electric vehicle thermal management, developed in collaboration with Vantage Power and Brunel University with UK Government Faraday funding; IsoMat™ Building Cladding for thermal management in buildings; and IsoMat™ Network Rail, launched in August 2025 through a strategic partnership with Network Rail to thermally protect signaling equipment cabinets.
The business model combines direct hardware sales with licensing of the underlying IsoMat™ IP, with pricing structured on a quote basis. Customer segments span commercial refrigeration operators, EV battery manufacturers, building/construction, and rail infrastructure, with Network Rail representing the most recently disclosed anchor customer. No revenue figures, equity funding rounds, or recurring revenue mechanics are disclosed.

Flint Engineering product offering
Product offeringCore offering
Flint Engineering develops and sells IsoMat™, a patented isothermal energy management system (EMS™) that controls the movement of thermal energy from warm to cool areas without external power. The technology is applied to commercial refrigeration shelving, EV battery cooling plates, building cladding systems, and railway signalling cabinet protection.
Product overview
Flint Engineering offers the IsoMat™ isothermal energy management system as its core technology, which is applied across multiple product lines: Commercial Refrigeration Shelving (energy-efficient shelf replacement for retail refrigeration), EV Battery Pack (thermal management for electric vehicle batteries), Building Cladding (self-sufficient building cooling with thermal energy harvesting), and Network Rail applications (infrastructure thermal protection). The company focuses on sustainable, energy-efficient solutions that reduce reliance on traditional energy sources.

Brands
- IsoMat™: Patented isothermal energy management system (EMS) for thermal energy management. Applied to commercial refrigeration, EV battery packs, and building cladding.
Products and services
- IsoMat™ Commercial Refrigeration Shelf Energy-efficient shelving for commercial refrigeration cabinets that replaces traditional steel shelves. Cools merchandise directly and improves air circulation, resulting in 8-30% energy savings and consistent temperatures throughout the cabinet.
- IsoMat™ EV Battery Pack Thermal management system for electric vehicle batteries developed with Vantage Power, Brunel University and UK government Faraday funding. Maintains all battery cells at 25°C ±1°C, extending range and battery life while enabling faster charge and discharge.
- IsoMat™ Building Cladding Building cladding system that harnesses thermal energy and generates electricity using thin film solar PV. Provides self-sufficient cooling via adsorption chiller integration, delivering 400W cooling per 1kW heat harvested and 200W electricity per m2, with cooling capacity ranging from 10kW to 1MW.
- IsoMat™ Network Rail Patented, power-free thermal management technology designed in partnership with Network Rail to protect signalling cabinets from extreme summer heat on the UK rail network. Works silently without maintenance, reducing failures and delays.
Quantifiable outcome
- 8% to 30% energy savings in commercial refrigeration
