What Lumo does
Lumo Energy Limited is a UK-based, privately-held software company founded in 2023 and headquartered at 39 Aberdeen Avenue, Cambridge. The company has built a software-only, hardware-agnostic home energy optimisation platform that connects to existing residential solar inverters, batteries, EV chargers, and heat pumps via secure device APIs and automatically makes storage, usage, and export decisions every five minutes based on tariffs, weather forecasts, solar generation predictions, household consumption patterns, and live grid price signals. The platform works across multiple device brands (GivEnergy, Tesla, FoxESS, Sungrow, Growatt and others), tariff structures, and utilities, and enables connected home batteries to participate in UK grid flexibility programmes including wholesale markets, the capacity market, and the Demand Flexibility Service.
Lumo's commercial architecture rests on three go-to-market vectors: (1) a direct-to-consumer self-serve app on which UK homeowners with compatible systems can connect devices in minutes at no cost; (2) a B2B2C channel of accredited UK solar and battery installers who bundle Lumo into new system installations and earn recurring revenue of £50-£200 per household per year from flexibility earnings; and (3) enterprise/embedded relationships with new build property developers and OEM manufacturers (battery, inverter, and connected device makers) targeting zero-bill homes and hardware-integrated optimisation.
The revenue model is a transaction-fee share of grid flexibility earnings. After deducting a £50 annual platform fee, Lumo retains 50% of flexibility revenue generated by enrolled batteries, paying the remaining 50% to the homeowner (paid via the in-app Lumo Wallet, withdrawable from £10). For installer-partner-led deployments, the installer receives the recurring share. The company is backed by Fuel Ventures and South East Angels, holds independent EPVS validation of its tariff savings methodology (up to 30% additional savings), and operates with a small team (1-10 employees). Its leadership includes co-founder Alexander Gosling, Chief of Product Barney Scott (ex-Kaluza, ex-Ovo), and Chief of Software Guill Torrente (ex-Credit Suisse, BofA, XBTO), with an advisory bench drawn from Kaluza, Ovo Energy, EDF Renewables, Granular Energy, and Engensa.

Revenue model
- Grid Flexibility Revenue Share: Lumo receives revenue from grid operators when home batteries participate in flexibility programmes. After deducting a £50 per year platform fee, Lumo shares 50% of the remaining amount with customers as Flexibility Earnings. Formula: Your Flexibility Earnings = (Flexibility Revenue - £50 platform fee) x 50%.
- Installer Partner Revenue Share: Installers earn recurring revenue of typically £50-£200 per household, per year from grid flexibility earnings generated by Lumo-optimised systems. This creates a recurring revenue stream for installer partners.

Lumo competitors and assessment
Company assessmentDirect peers
- GridBeyond: Demand response and distributed energy flexibility platform operating in the UK and Ireland. Comparable in operating batteries and DERs for grid flexibility revenues, though primarily serving commercial customers rather than residential households.
- PassivSystems: UK home energy management software focused on optimizing heating, solar and battery systems for households and utilities. Comparable software-led approach to residential energy optimization in the UK market.
- Kaluza: Energy optimization software platform spun out of Ovo Energy that optimizes distributed energy assets (EVs, heat pumps, batteries) for utilities and consumers. Highly comparable to Lumo's software-only, multi-vendor optimization approach, though operating at utility scale rather than direct-to-consumer.
- Moixa: UK-based home battery optimization software (now part of EDF). Directly comparable to Lumo in optimizing residential solar-plus-battery systems and participating in UK flexibility markets for homeowner earnings.
- Tibber: Norwegian digital energy retailer with smart-home tariff optimization and battery integration across European markets. Comparable business model around dynamic tariff optimization and hardware-agnostic energy management, though geographically focused on Nordics.
Broad incumbents
- Octopus Energy: Major UK energy retailer with its own smart tariff products, EV and heat pump integration, and home battery optimization initiatives (including Kraken platform). Overlaps with Lumo's value proposition but as part of a much broader retail energy business.
- Tesla Energy: Powerwall battery and Tesla app ecosystem offering automated solar-plus-battery optimization for homeowners. Comparable in the optimization and grid participation value proposition, but tied to Tesla's own hardware.
- SolarEdge: Global solar inverter manufacturer with an energy management ecosystem and home battery products. Overlaps with Lumo in optimizing residential solar-plus-storage but primarily within its own hardware ecosystem.
- EDF (UK): UK energy incumbent that owns Moixa and operates residential flexibility and solar-plus-battery offerings. Comparable in targeting UK homeowners for solar/battery optimization, but at utility scale with bundled retail energy products.
Others
- Enode: Device connectivity platform that Lumo relies on to integrate with home energy hardware. Functions as enabling infrastructure for Lumo and similar energy optimization players, rather than a direct consumer-facing competitor.
