London-based home energy optimization and automation company Tewke has secured £1.5 million in its second funding round to accelerate development of its flagship product, Tap.In. The raise saw participation from JamJar Investments, Cur8 Capital, Energy Mix Ventures and Project Ventures.

According to the announcement on Tuesday, Tap.In is a smart light switch designed to simplify home energy management. The device requires no rewiring and operates without a neutral wire, making it compatible with more than 90 percent of U.K. homes. 

In addition to functioning as a smart switch, Tap.In helps households align electricity use with time-of-day tariffs, enabling users to lower both energy bills and carbon emissions.

“Having the backing of some of the U.K.’s most respected investors, including JamJar and a founder of one of Britain’s most successful tech companies, is a powerful validation of our team, our mission and the product we’ve built. We’re not just optimizing energy; we’re creating a more intelligent, sustainable and user-centred way of living,” Piers Daniell, CEO of Tewke, said in a statement.
