Growing Underground
London's underground farm growing microgreens 33 meters below the city in former WWII tunnels raised £8M and entered administration in 2023 as energy costs proved unworkable.
Evaluating only Growing Underground’s profile at its peak — without knowing the outcome — the model ranked Unit economics as the #1 likely cause. That’s exactly how it died.

Documented cause
Growing Underground was founded in 2015 by Richard Ballard and Steven Dring, farming microgreens and salad leaves in former WWII air-raid tunnels 33 meters below Clapham in South London. The concept was compelling: climate-controlled growing, zero pesticides, 10-minute delivery to central London restaurants. The company raised approximately £8M and supplied restaurants including Michelin-starred establishments. But the energy costs of running LED lighting, climate control, and logistics in a small underground farm were prohibitive — energy represented up to 30% of operating costs, and the post-Ukraine energy price crisis of 2022 made operations economically non-viable. Growing Underground entered administration in January 2023.
Lesson
“Model your energy costs under a 3x price scenario before committing to an energy-intensive facility — if it doesn't survive that scenario, the business model is fragile.”
