What Warmup does

Warmup Plc is a UK-based manufacturer of electric and hydronic (water-based) underfloor heating systems, founded in 1994 by Andrew Stimpson (currently Chairman and CEO) and headquartered in London. The company's core technology comprises heating cables and mats (electric portfolio, including the proprietary DCM-PRO decoupling membrane system and a 1.8mm Loose Wire cable claimed as the thinnest on the market), low-profile and traditional hydronic pipe systems, and a smart controls ecosystem led by the Matter-compatible 7iE thermostat, the MyHeating app, and Konekt wireless multi-zone controls. Warmup operates an ISO 9001:2015 certified British manufacturing operation and holds CE, BEAB, cUL, CSA, FIMKO, and UL certifications, with 2.5 million systems installed across 72 countries and recognition including the Queen's Awards for Enterprise 2020.

The business is primarily a hardware seller, with electric systems starting at £14.58/m² and complete systems ranging £409-£929, plus thermostats priced from £74.77 and hydronic systems from approximately £25/m². Revenue is complemented by a recurring-style Smartcare AI customer support service and the AutoSwitch energy tariff-switching app. Warmup reaches customers through five channels: direct e-commerce via warmup.co.uk with online quoting tools, a nationwide UK retail stockist network, a dedicated trade counter, certified Pro Electric/Pro Hydro installer programs, and a Projects Division targeting enterprise specifications (Heathrow Terminal 3, Great Eastern Hotel, London Docks Phase 1) and mid-market developers. Customer segments span homeowners/renovators, trade professionals (electricians, plumbers, tilers), builders/developers, architects/specifiers, and resellers, supported by Pro training tracks and professional design tools.
