Glow Green

What Glow Green does

Glow Green Limited is a privately held UK residential energy installation company founded in 2011 by Lloyd Greenfield and headquartered in Bournemouth. The company installs and maintains seven core product categories — boilers (Worcester Bosch, Vaillant, Glow-worm), solar PV panels (DMEGC, Perlight), air source heat pumps (Vaillant aroTHERM Plus), air conditioning (Hitachi, Samsung, Daikin), battery storage (Tesla Powerwall 3, Duracell Energy Dura5, Fox Cube), and EV chargers (Tesla Wall Connector, Duracell Energy, Foxx ESS) — and is differentiated by aggregating tier-1 manufacturer products under one nationwide installation service rather than building proprietary hardware. Technology centers on a bespoke online quoting engine, Google Earth-based solar system design, and a 100% installation audit process; the company holds MCS, NICEIC, HIES, Gas Safe, Refcom, and FCA credit broking (RN: 692433) certifications. It has completed over 50,000 installations and carries an Excellent rating on Trustpilot with 14,871+ verified reviews.

The business operates a direct-to-consumer model with a digital quoting flow that converts without an in-person survey, supplemented by phone-based account management and a distributed network of vetted local engineers covering the entire mainland UK. Top-of-funnel customer acquisition is driven by SEO-led content, comparison platform presence (Uswitch, Go Compare, MoneySupermarket, The Independent), and a referral program offering up to £500 savings. Revenue is generated primarily through one-time installation sales and equipment resale, with a secondary stream of recurring service and maintenance contracts (Glow Care 100 and Glow Care 300, from £7.99/month), lender commissions on arranged consumer finance, and government-grant capture under the Boiler Upgrade Scheme (£7,500 per qualifying heat pump install).

The company is founder-owned and organically bootstrapped, with no disclosed venture, private equity, or institutional investment. Its expansion is shaped by strong UK tailwinds: a 182% year-on-year surge in solar panel demand in 2026 driven by energy cost concerns, the UK Boiler Upgrade Scheme grant, accelerating EV adoption, and policy-driven decarbonization of home heating. Strategic positioning emphasizes cross-selling solar-plus-battery-plus-EV systems to boiler customers, premium manufacturer partnerships (Tesla, Vaillant), and converting one-off installers into recurring maintenance subscribers under the Glow Care contract, while distribution leverage comes from national comparison site placements and editorial third-party validation including The Independent's Best Solar Panel Installer for 2025.

Broad incumbents

• Octopus Energy: UK energy supplier rapidly expanding into heat pump, EV charger, and solar PV installations with bundled supply-plus-install offerings. Directly comparable to Glow Green on product categories and customer base, but operates at far larger scale and under an integrated retail-energy model.
• British Gas: UK incumbent energy supplier and the largest boiler installer in the country, also expanding into heat pumps, solar and EV charging via its Local Heroes platform. Overlaps Glow Green across every product category with substantially larger marketing, finance, and customer base.
• EDF Energy: UK energy supplier installing solar PV, battery storage, EV chargers and heat pumps under its renewables and home services arms. Comparable to Glow Green across multiple product categories with the advantage of an energy-supply bundle.
• E.ON UK: UK energy supplier with a home-solutions division installing heat pumps, solar, EV chargers and smart-home products. Competes with Glow Green for the same electrification-driven homeowner wallet, with greater financial firepower.
• OVO Energy: UK energy supplier expanding into heat pumps, EV charging and home energy services. Direct overlap with Glow Green's electrification-driven offering, particularly on heat pumps, but operating from a much broader retail-energy base.
• ScottishPower: UK energy supplier (Iberdrola group) with solar, battery, EV charger and heat-pump installation offerings. Comparable product set to Glow Green with the backing of an integrated energy supply business.

Direct peers
