Tewke raises £1.5M to expand its AI-driven home energy platform

Feb 24, 2026 | By Kailee Rainse

London-based Tewke, a company focused on energy optimisation and home automation, has raised £1.5 million in its second funding round. Investors in the round include JamJar Investments, Cur8 Capital, Energy Mix Ventures, Project Ventures, and angel investor Vlad Yatsenko, who is the co-founder and CTO of Revolut.

Founded in 2020 by Piers Daniell and Rowan Dixon, Tewke builds smart home technology that makes energy management simpler. Its main product, Tap, is designed and engineered in the UK and does not require any rewiring. It works in homes without a neutral wire, making it compatible with more than 90% of UK properties. The company presents Tap as a simpler alternative to complex smart home systems that require professional installation.

In addition to controlling lighting, Tap helps households optimise energy use by shifting electricity consumption to cheaper, off-peak time-of-day tariffs, reducing both costs and carbon emissions. This product is part of Tewke’s wider strategy to improve home energy efficiency using contextual, AI-powered intelligence. The company develops its core technology in-house, including patented hardware, firmware, and its own operating system, Tewke OS.

Piers Daniell, co-founder and CEO of Tewke, said the company’s goal extends beyond energy optimisation to creating a more intelligent, sustainable, and user-centred living environment.

Building next-generation electronics and AI in the UK has been a monumental technical challenge. Seeing people install Tap in minutes and start saving energy immediately is a powerful reward. This funding enables us to scale what we’ve proven works and double down on engineering excellence,

added Rowan Dixon, co-founder of Tewke

In 2025, Tewke launched TewkeAI in collaboration with Google. This contextual AI framework uses data from Tap’s nine built-in sensors to analyse activity, movement, air quality, and temperature patterns inside the home.

The new funding will help the company strengthen its go-to-market strategy and expand its engineering team. This includes developing advanced neuro-symbolic AI systems aimed at improving energy efficiency in homes. Tewke’s growth is also supported by non-equity funding from Innovate UK.
