Carbon Legacy

What Carbon Legacy does

Carbon Legacy Ltd is a UK private limited company founded in 2009 by David Hill, headquartered in East Leake, Leicestershire, that designs, supplies, and installs renewable energy systems for residential, commercial, agricultural, and self-build customers. Its core offering spans three product lines: solar PV (domestic and commercial arrays using AIKO panels and German mounting systems), heat pumps (air source, ground source, and borehole systems from NIBE and Samsung), and battery storage (Tesla Powerwall 2/3 and Dyness Powerbox G2 with Solis hybrid inverters). The business also advises self-builders on fabric-first energy efficiency and administers Boiler Upgrade Scheme (£7,500) grant applications on behalf of customers via Ofgem.

The company operates a sales-led, project-based model: free on-site consultations, bespoke quotes, and staged deposit/delivery/commissioning payments, with revenue generated from equipment supply, installation labour, and recurring aftercare and maintenance contracts. All installations are MCS-certified, with additional accreditations from NAPIT, RECC, Which Trusted Trader, Tesla, and NIBE. Carbon Legacy is concentrated geographically in the East Midlands (Nottinghamshire, Derbyshire, Leicestershire), with 2,500+ total installations and 200+ commercial projects completed over its 15-year history. The customer base is highly fragmented — long-tail residential work supplemented by episodic commercial jobs across sports clubs, automotive retail, estates, schools, and farms — and the company is privately held by founding management with no external investment disclosed.

Direct peers

• Geo Green Power: UK-based solar PV and heat pump installer offering integrated renewable energy solutions to residential and commercial customers. Closely comparable in service mix (solar + heat pumps), MCS accreditation, and project-based GTM with similar ticket sizes.
• Empower Energy: UK regional renewable energy installer specializing in solar PV, battery storage, and EV charging for domestic and commercial customers. Comparable in size, accreditation profile, and target customer segments.
• Midsummer Energy: UK solar PV and battery storage company distributing equipment and offering installation services. Comparable in product portfolio (panels, inverters, batteries) and MCS-aligned delivery, with overlap on premium European equipment brands.
• Solarsense: UK solar PV and renewable energy installer serving residential and commercial customers with integrated solar and battery solutions. Directly comparable in end-to-end project model and accreditation-driven GTM.
• Sunsure Energy: UK solar PV installer focused on residential and small commercial systems. Comparable in customer segments, project-based delivery model, and MCS-certified installation footprint.
• Project Solar UK: UK solar PV installer with national reach and in-house panel manufacturing. Comparable in core residential solar offering with MCS-aligned installation model, though at a larger scale.

Emerging players

• Otovo: Norwegian-headquartered digital residential solar installer that has expanded into the UK market. Comparable in solar-plus-battery offering for homeowners, but applies a tech-enabled subscription/financing model rather than Carbon Legacy's bespoke-quote GTM.

Broad incumbents

• Octopus Energy: Major UK energy retailer that has launched in-house solar, heat pump, and EV installation services. Comparable as a channel for end customers installing residential renewables, but operates at vastly larger scale and bundles installation with energy supply.
• EDF Energy: One of the Big Six UK energy suppliers offering solar PV and heat pump installation services to residential and commercial customers. Comparable in end-customer offering but competes from a utility-scale position with cross-sell from energy supply contracts.
• E.ON UK: Major UK energy supplier with a dedicated solar, battery, and heat pump installation business. Comparable in integrated residential renewable offering, but operates with significantly broader geographic reach and brand budget than Carbon Legacy.
