What's the deal? FurbnowDealroom has a profile for this one.

Try Dealroom →, SFC CapitalDealroom has a profile for this one. Try Dealroom →, and angel investor Daniel Luhde-Thompson joining.
What's the endgame? Furbnow guides households through energy retrofits via a managed marketplace, positioning itself as an independent advisor. It conducts whole-house surveys, drafts "Home Energy Plans," then shepherds vetted contractors through installation.
Why now? UK policy is throwing real money at residential decarbonisation. The Boiler Upgrade Scheme now offers £7,500 grants for heat pumps, and a temporary zero-rate VAT on energy-saving materials runs through early 2027.
Founder Becky Lane told The Guardian that inquiries jumped 42% month-on-month after a surge in interest in early 2026, driven mostly by solar panels and heat pumps.
Local first: Furbnow partners with councils across England, including Cotswold District Council and Forest of Dean District Council, as a one-stop retrofit provider. West Yorkshire's mayoral-backed Home Energy West Yorkshire program lists it as a service supplier.
The company emerged from the Nesta and Founders Factory Mission Studio in 2022, a cohort built to tackle climate challenges. An earlier pre-seed round in January 2024 raised £950,000 from SFC CapitalDealroom has a profile for this one. Try Dealroom →, Norrsken Launcher, and Luhde-Thompson, plus grant funding from Innovate UK.
What could go wrong? Much of the demand rests on subsidies. The Great British Insulation Scheme ends on March 31, 2026, and whether the market proves durable — or just a subsidy-fuelled blip — is the question Furbnow must now answer.
The signal: At £2.5 million, Furbnow's raise ranks among the top 10% of all seed rounds in UK energy. It reflects investor appetite for startups working within policy frameworks as government incentives push home decarbonisation up the agenda.
