What HEATZONE SERVICES LTD does

Heatzone Services Ltd is a UK private limited company founded in 2018 and headquartered at the Porter Building in Slough. The company operates as a direct-to-consumer intermediary for the UK Government's ECO4 (Energy Company Obligation Phase 4) scheme, facilitating the delivery of free boiler replacements, first-time central heating installations, insulation upgrades, and heat pump installations to eligible low-income households. Customers qualify based on receipt of specific government benefits, household income under £31,000, and property Energy Performance Certificate ratings of D, E, F, or G. The company has served over 2,000 customers and completed more than 750 installations, supported by a 21-person team including certified engineers.

The core product portfolio centers on two grant programs — the Free Boiler Grant and First-Time Central Heating Grant — with add-on insulation and heat pump services bundled under the same ECO4 framework. Customer acquisition is driven primarily through the company website, which features an online eligibility checker that completes qualification assessment in under 60 seconds, supplemented by a multi-line phone contact center and organic search visibility for high-intent UK grant keywords. The full customer journey — eligibility check, free property survey by certified professionals, and installation — is handled in-house or via a partner engineer network.

Heatzone does not operate a software platform or proprietary technology stack; the business is a services-led installation contractor funded by energy suppliers under the ECO4 government mandate. Revenue is generated on a managed-services basis per completed installation, with no direct charges to eligible customers. There are no disclosed funding rounds, parent companies, institutional investors, or M&A activity; the company appears to be founder/independently owned and operates exclusively in the UK market.

Core offering

Heatzone Services Ltd facilitates the installation of free boiler replacements, first-time central heating systems, and complementary insulation upgrades for eligible UK households under the UK Government's ECO4 (Energy Company Obligation Phase 4) scheme. The company acts as an intermediary between low-income homeowners and the energy suppliers that fund the installations, providing end-to-end service from online eligibility assessment through free property survey and certified installation. All services are 100% funded at no cost to qualifying customers.

Product overview

Heatzone Services Ltd operates as a single integrated service offering centered on the UK Government's ECO4 (Energy Company Obligation Phase 4) scheme. The company's core portfolio consists of two main grant programs: Free Boiler Grants for replacing old boilers and First-Time Central Heating Grants for households without existing central heating systems. Both services are delivered through a unified eligibility checker process and may include complementary insulation services (loft, wall, cavity wall). All offerings are 100% funded for eligible low-income households receiving government benefits. The company does not operate a platform-plus-modules architecture; rather, it provides these grant facilitation services as a coordinated end-to-end offering.

Broad incumbents

• Daikin UK: Daikin UK is a leading heat-pump manufacturer with an installer-partner programme that delivers air-source and ground-source heat-pump installations to UK households. It is comparable to Heatzone in the residential heat-pump installation end of the business, particularly as Heatzone pivots toward heat pumps under future ECO-type schemes.
• British Gas: British Gas is the UK's largest energy supplier and an approved ECO4 partner that offers free boiler replacements and home energy efficiency upgrades to eligible households. It competes directly with Heatzone for the same ECO4-funded customers but operates as a broad utility rather than a specialist installer.
• E.ON UK: E.ON is a major UK energy supplier that participates in the ECO4 scheme, providing free boiler replacements, insulation, and other energy-efficiency measures to eligible households. Like British Gas, it is a broad incumbent with a wider energy-bill relationship compared to Heatzone's specialist installation focus.
• EDF Energy: EDF Energy is one of the UK's "Big Six" energy suppliers and an approved ECO4 partner delivering free boiler and insulation upgrades to eligible customers. It overlaps with Heatzone on ECO4-funded residential heating and insulation work but operates at much larger scale as a utility.
• ScottishPower: ScottishPower is a major UK energy supplier and ECO4 partner offering free boiler replacements, central heating, and insulation upgrades to eligible households. It is comparable to Heatzone in that it pursues the same ECO4-funded residential customers, though it does so as part of a wider utility portfolio.
• Worcester Bosch: Worcester Bosch is the UK's leading boiler manufacturer and runs an accredited installer network that delivers boiler and heating system installations, including via ECO-funded programmes. It sits adjacent to Heatzone as an equipment supplier and installer-network operator rather than a direct grant-funded competitor.
• Octopus Energy: Octopus Energy is a UK energy supplier with an expanding home energy services arm that includes heat-pump installation and ECO-related upgrades. It targets many of the same low-income and decarbonisation-focused households as Heatzone, but with much broader brand reach and capital backing.

Direct peers

• Glow Green: Glow Green is a UK boiler installation specialist that delivers boiler replacements, central heating, and renewable heating solutions to residential customers, often via government grant schemes. It is comparable to Heatzone in customer segment, service mix, and installer-led operating model.
• HelpLink UK: HelpLink is a UK specialist boiler installation company that participates in government-funded schemes such as ECO4 to deliver free boiler replacements and central heating to eligible households. It is the closest direct peer to Heatzone — a similarly sized, specialist ECO-funded residential heating installer rather than a broad utility.
• HomeServe: HomeServe is a UK home-services provider specialising in boiler/heating cover, plumbing, and electrical repairs with a national network of engineers. It is a direct peer to Heatzone in that it sells and delivers residential boiler and heating services to UK homeowners, though its primary monetisation is subscription cover rather than ECO-funded installation.
