The director
Louis Fox
Born in 2007 and founder of Mayfair Gas in 2025, Louis built the company around one idea: heating engineering should feel like a concierge service. Every job is booked, tracked and reported to the standard he'd expect in his own home.
The all-electric ID. Buzz fleet — black with gold detailing — keeps London's air clean while we keep its homes warm.
No heating? We're already on the way.
Call any hour of any day and speak to a real engineer, not a call centre.
