What Tepeo does
Tepeo is a British clean technology company founded in 2018 by engineer Johan du Plessis and headquartered in Winnersh, Wokingham, where it designs, manufactures, and services its products under one roof. Its core product is the ZEB (Zero Emission Boiler), a heat battery boiler that stores electricity as heat in a proprietary high-density ceramic core (40kWh usable capacity, 15kW peak output, 35°C–80°C temperature range, 4.5-hour charge time) and releases that heat through standard wet central heating systems — radiators and underfloor — as a direct replacement for gas, oil, LPG, or direct electric boilers without requiring any outdoor unit.
The ZEB is paired with a proprietary smart charging algorithm that optimises charging against weather forecasts, home usage patterns, energy tariffs, and grid carbon intensity; a mobile app (iOS and Android) provides live status, carbon tracking, Away Mode, and Boost controls; and a cloud-based remote monitoring platform underpins the tepeo Care Plan subscription (£12.75/month or £179/year Health Check). Hardware is sold direct-to-consumer at £6,000 inclusive of VAT and delivery, with installation handled by the certified tepeoPRO installer network across England and Wales. Consumer finance is offered via Vendigo and Humm, and the company is an official Works with Octopus partner, integrating with Octopus Agile, Go, and Intelligent Go tariffs.
The business targets three customer segments: (1) primary — homeowners replacing fossil fuel boilers or seeking heat pump alternatives for space-constrained or heritage-protected properties; (2) social housing providers needing low-disruption retrofits for high-density buildings; and (3) property developers and housebuilders needing Future Homes Standard compliance. Go-to-market blends direct sales, an installer channel, content marketing, cost/carbon calculator tools, and active government engagement for Boiler Upgrade Scheme inclusion. The company has raised approximately £13 million in total (£2.5M Clean Growth Fund in July 2021, £10.5M BGF-led Series A in December 2022), achieved B Corp certification in 2024 with a 97.8 Impact Assessment score, and was named an Ethical Consumer Best Buy in 2025.

Tepeo product offering
Product offeringCore offering
Tepeo manufactures and sells the ZEB (Zero Emission Boiler), an electric heat battery boiler that stores electricity as thermal energy in a high-density ceramic core (40kWh capacity) and releases it through existing wet central heating systems (radiators or underfloor) when heating is needed. The ZEB is designed as a direct low-carbon replacement for gas, oil, LPG, and direct electric boilers in UK homes, integrating with smart tariffs to charge during off-peak periods.
Product overview
Tepeo offers a unified product portfolio centred on the ZEB (Zero Emission Boiler) heat battery system. The core offering is the ZEB itself — an electric heat battery boiler that stores energy during off-peak periods and delivers heating through existing radiators. This core product is complemented by the tepeo App for smart monitoring and control, and the tepeo Care Plan for ongoing maintenance and support. Together, these components provide an integrated low-carbon heating solution for UK homes replacing fossil fuel boilers.

Tepeo competitors and assessment
Company assessmentDirect peers
- Sunamp: UK-based manufacturer of phase-change material (PCM) heat batteries for hot water and space heating. Already appears as a Tepeo integration partner (Sunamp Thermino alongside ZEB) and competes directly in the residential heat-battery category.
- Mixergy: UK smart hot-water cylinder manufacturer using thermal storage technology. Competes in the same residential thermal storage and smart-tariff integration space as Tepeo, targeting decarbonization of home heating.
Broad incumbents
- Baxi: Major UK boiler manufacturer (part of BDR Thermea Group) offering incumbent gas, hydrogen-ready, and heat pump solutions. Represents the established competition Tepeo is displacing in fossil-fuel boiler replacements.
- Worcester Bosch: UK's largest boiler brand, now offering hybrid heat pump + boiler systems. A dominant incumbent in residential heating with extensive installer networks competing for the same replacement boiler customers.
- Daikin: Global HVAC leader with a major UK heat pump push. Competes for low-carbon heating share and benefits from £7,500 BUS grants that dwarf Tepeo's £2,500 early grant match.
- Mitsubishi Electric: Leading air-source heat pump manufacturer in the UK with established Ecodan range and installer network. The dominant low-carbon heating incumbent competing against ZEB's value proposition.
- NIBE Energy Systems: Swedish manufacturer of heat pumps and heating solutions with strong UK presence. Competes in low-carbon residential heating, particularly for off-gas-grid and new-build segments Tepeo also targets.
Emerging players
- Kensa Heat Pumps: UK-based ground-source heat pump specialist. Targets similar decarbonization-focused retrofits and new-build developments, offering an alternative low-carbon pathway for the same customers.
- EnergyNest: Norwegian thermal energy battery company using concrete-based modular storage. Targets industrial and commercial heat decarbonization — adjacent technology that could expand into residential markets competing with Tepeo.
Others
- Octopus Energy: UK energy retailer and Tepeo integration partner (Works with Octopus). Not a direct product competitor but a key channel/ecosystem enabler whose smart tariffs and Kraken platform materially drive ZEB's economics and demand.
