Key people at Tepeo.
Tepeo has raised $16.0M in total across 2 funding rounds.
Tepeo develops zero-emission boilers (ZEBs) that directly replace conventional gas or oil heating systems, offering a low-carbon solution for homes. This technology integrates smart operational capabilities, providing a flexible and efficient system designed to simplify the transition to sustainable home heating while preserving a familiar user experience.
Founded in 2018 by Johan du Plessis, Tepeo originated from the insight that consumers needed a straightforward, intelligent, and economical route to decarbonize their home heating. Du Plessis's aim was to develop accessible technologies that would accelerate a widespread shift away from fossil fuels in residential applications.
Tepeo targets homeowners seeking practical low-carbon heating alternatives, specifically those desiring an easier transition from fossil fuels without extensive system overhauls. The company's vision is to become a leader in low and zero-carbon heating and grid flexibility solutions, fundamentally transforming how homes are heated to achieve a fully carbon-free future.

Tepeo is a British ClimateTech company founded in 2018 that develops the ZEB (Zero Emission Boiler), a smart heat battery boiler designed as a low-carbon, cost-effective alternative to fossil fuel and traditional electric boilers.[1][2][3] The ZEB stores heat generated from off-peak, renewable electricity in a highly insulated core, delivering whole-home heating with half the running costs of standard electric boilers (up to £1.5k annual savings on smart tariffs) and zero direct emissions, while installing in 1-2 days using existing plumbing and radiators.[2][3][5][6] It targets UK households unsuitable for heat pumps—potentially 40% of properties—serving homeowners seeking simple decarbonization amid rising fossil fuel bans, with strong growth via a nationwide installer network and accolades like 2024 Ashden Award and B Corp certification.[3][4][5]
Tepeo emerged in 2018 from a mission to provide a simple, affordable path off fossil fuel heating, driven by the need for low-carbon solutions beyond heat pumps.[1][2][3] After three years of intensive R&D—designing, testing, and iterating thermal storage prototypes—the company launched the ZEB in 2021 as a British-engineered heat battery that intelligently charges overnight and adapts to weather, tariffs, and usage via an app.[2][3] Pivotal moments include rapid scaling through tepeoPRO installer training, employing 68 people in UK manufacturing, and earning landmark B Corp status in November 2024 as the first domestic heating manufacturer, led by CEO Johan du Plessis who emphasized industry-leading ethics.[3][4][5] This trajectory reflects founders' focus on practical innovation for the UK's net-zero push.
Tepeo rides the UK heating decarbonization wave, where homes account for 31% of household emissions and fossil fuel boilers face bans in new builds from 2025, demanding diverse low-carbon options.[2][5] Its timing aligns with grid-scale renewables growth, smart tariffs, and net-zero mandates, filling gaps for 40% of properties where heat pumps falter due to space or retrofit costs—accelerating electrification without infrastructure overhauls.[2][5][6] By manufacturing locally, upskilling installers, and pioneering B Corp standards, Tepeo influences the ecosystem: it educates consumers, boosts green jobs, and pressures incumbents toward sustainability, proving thermal storage as a scalable bridge to full renewables.[4][5]
Tepeo's ZEB positions it for explosive growth as UK boiler mandates tighten and electrification incentives expand, potentially capturing millions of off-gas-grid homes via its installer network.[3][5] Expect expansion into commercial applications, deeper AI optimization for dynamic grids, and international pilots as global net-zero policies mirror the UK's—bolstered by B Corp credibility attracting impact investors.[4] With trends like cheaper batteries and renewable overbuild favoring smart storage, Tepeo's influence could redefine heating as a "heat your home, not the planet" standard, leading the charge from fossil fuels to efficient, accessible ClimateTech.[1][3]
