What Furbnow does
Furbnow is a UK-based climate technology startup that provides whole-house energy retrofit planning services to residential homeowners, positioning itself as an independent advisor rather than an installer or product vendor. The company's flagship deliverable is the BuildPack — a comprehensive, sequenced retrofit plan produced from a ~2-hour professional home survey (PAS 2035 compliant), containing product specifications, materials, floor plans, drawings, and installer instructions. Underpinning the service is a digital twin energy modelling workflow that simulates upgrade options for individual properties and sequences interdependent measures (e.g., windows before IWI, MVHR after airtightness testing) to maximize energy performance and avoid common pitfalls such as damp or oversized heat pumps.
Revenue is generated primarily through a one-time, pay-in-advance BuildPack fee priced by property size (small 1–2 bedrooms, medium 3–4 bedrooms, large 5+ bedrooms), with optional bolt-on surveys (Heat Loss Estimator, Thermographic Assessment) sold on top. A secondary transaction-based stream comes from facilitating quotes between homeowners and vetted contractors from Furbnow's installer network. The go-to-market combines direct-to-consumer self-serve booking through furbnow.com with B2G2C partnerships via local councils, including Birmingham City Council and Surrey County Council, where Furbnow's service is embedded in subsidized retrofit programs such as Surrey's Home Energy Improvement One-Stop Shop.
Furbnow was founded by Becky Lane (former GB rowing champion) and is led alongside Laurence Watson (Chief Product & Technology Officer and Data Protection Officer). The company is headquartered in Birmingham, UK, with active service coverage across multiple English regions. As of 2024 it had served 900+ homeowners; by February 2026 it reported 750+ homes retrofitted and cumulative funding of £3.5M, led by SFC Capital with participation from Norrsken Accelerator and angel investor Daniel Luhde-Thompson. Notable recognition includes selection for Tech Nation's first climate startup cohort and coverage in Grand Designs, The Guardian, The Times, Homebuilding & Renovating, and Woman & Home.

Revenue model
- Home Energy Assessment & Plan (BuildPack): Furbnow charges homeowners for a professional home energy survey followed by delivery of a detailed BuildPack — a whole-house plan with phased upgrades, product specifications, installer instructions, and technical drawings. Pricing is tiered by property size (small/medium/large based on bedroom count). Payment is required in advance of the survey. Additional services include optional bolt-on surveys such as Heat Loss or Thermographic assessments.
- Installer Network / Supply Chain Management: Furbnow connects homeowners with vetted, specialist contractors from its supply chain for the actual installation of upgrades. While the primary revenue is the BuildPack fee, the company may earn referral fees or margin on contractor quotes facilitated through its platform.

Furbnow competitors and assessment
Company assessmentDirect peers
- Cosy: UK home energy advisory service that helps homeowners plan whole-house retrofit, including insulation, heat pumps, and solar. Directly comparable independent advisor positioned between installer sales pitches and homeowner decisions.
- Giraffe Energy: UK-based climate tech startup focused on whole-house home energy retrofits with independent advisory and project coordination. Closest direct competitor to Furbnow's home survey + plan + installer coordination offering.
Emerging players
- Cotswold Energy (Retrofit Coordinator): Independent retrofit coordinator / coordinator working under PAS 2035 standards. Similar role to Furbnow's retrofit assessors, providing a competitive template on UK regional service delivery for whole-house assessments.
- Energiesprong UK: UK programme delivering whole-house retrofit to net-zero standard using a fabric-first, pre-engineered approach. Shares Furbnow's whole-house philosophy and the pre-engineered BuildPack-style methodology but targets social housing at scale.
- Snugg (HomeLINK): UK home energy data and analytics platform helping landlords and homeowners measure energy performance. Adjacent to Furbnow's monitoring partnership with Chameleon — comparable in data layer of the retrofit value chain.
Broad incumbents
- British Gas (Energy Solutions / Home services): Major UK energy supplier with home insulation, boiler, and heat pump installation services. Notable as a broad incumbent Furbnow may displace or partner with via its installer network.
- Octopus Energy (Zero Bills / Heat Pump installs): UK energy supplier offering heat pumps, solar, and EV chargers with installation services. Competes in same end-market but bundles hardware instead of providing independent advice, making Furbnow's neutrality a differentiator worth monitoring.
- EDF Heat Pumps / Retrofit services: Another of the Big Six UK energy suppliers offering home energy upgrade products and installations. Adjacent incumbent with overlapping retrofit ambition.
Regional players
- Warmworks Scotland: Scotland-focused whole-house retrofit delivery service. Operates an analogous whole-house advisory + installation coordination model to Furbnow but restricted to Scotland; useful benchmark for regional service economics.
- Retrofit West / Retrofit West CIC: Regional retrofit delivery organisation for the West of England providing whole-house retrofit services through local councils. Listed in Furbnow's data as a regional partner, indicating overlap in operating geography and council-facing retrofit services.
