About Luthmore

Luthmore is a Wiltshire-based clean technology company developing a zero-emission alternative to the gas combination boiler. Founded in 2022 by former Dyson engineers Craig Wilkinson and Martin Gutkowski, the firm aims to decarbonize home heating with a practical solution for small to medium-sized homes. The founders' engineering background includes work on projects such as Dyson's abandoned electric car program. In January 2026, the company appointed Hervé Dehareng, a former senior innovation director at Dyson, as its chief executive to lead the next growth phase.

The company has developed the Luthmore Boiler, an all-electric, battery-powered system designed as a direct, 'drop-in' replacement for gas combi boilers. It fits in the same space and uses existing radiators and pipework, eliminating the need for disruptive installation works often associated with heat pumps. The unit features an integrated lithium iron phosphate (LFP) battery system which stores electricity from the grid during off-peak hours or from solar panels. This stored energy is then released to deliver high-power hot water (up to 30kW) and central heating (10kW), matching the performance of a traditional gas boiler without requiring a separate hot water tank.

Luthmore's business model targets homeowners, developers, councils, and social housing providers, positioning its product as a lower-disruption and more affordable upfront alternative to heat pumps. While the retail price is expected to be around £4,500, less than a typical heat pump installation, running costs are currently higher than gas boilers due to the price disparity between electricity and gas in the UK. The company has raised £12.4 million in total funding from backers that include housing developers, residential management companies, plumbing groups, and a £1 million investment from the British Business Bank via the South West Investment Fund.
