Residential energy optimisation platform for home electrification MoreLess
Lumo is a UK-based clean-tech startup developing a home energy management system (HEMS) to increase the efficiency of residential renewable energy technologies. The company was incorporated on June 24, 2023, and founded by Co-CEOs Alex Brummeler, an energy sector veteran, and Zander Gosling, founder of PurpleBricks. Their combined expertise in energy and scaling high-growth businesses underpins the company's strategy.
Lumo's core offering is an AI-powered software platform that connects to and optimises home energy devices like solar panels, batteries, EV chargers, and heat pumps. By forecasting household energy needs and solar generation against smart time-of-use tariffs, the system intelligently manages energy storage and grid interaction to boost the efficiency of solar and battery systems by up to 30%. This is designed to help homeowners reduce or eliminate electricity bills and shorten the payback period for their investments in green technology.
The company's business model involves partnering with accredited UK installers to offer Lumo-optimised solar and battery systems directly to homeowners. Customers who purchase a system through a partner gain full access to the Lumo app, which provides data on savings, earnings, and energy usage, alongside 24/7 system monitoring. The company secured an overfunded investment round led by Fuel Ventures in September 2025 to accelerate product development and scale its platform ahead of its commercial launch.
