Why it's on ClimateTicker

Sunamp makes a genuine climate contribution: its phase-change-material heat batteries reduce building heating emissions by enabling renewable energy storage and cutting standby heat loss, with independently documented CO₂ reductions of 4.6 kilotonnes by 2021 from installed units alone. The core product is a real decarbonisation tool, not a peripheral green add-on. However, the company is a privately held SME with limited public ESG disclosure, no evidence of SBTi-validated targets or CDP participation, and most impact claims rely on university-linked studies rather than independent third-party audits.

mitigationSunamp sells patented phase-change-material thermal storage units (the Thermino range and industrial equivalents) directly and via trade/distribution partners to residential, social housing, and commercial customers across the UK and internationally; it earns revenue from hardware sales and is expanding via manufacturing partnerships and geographic expansion into Italy, China, and North America.
