Our initiative, supported by government incentives, specifically targets low-income families, offering them free boiler installation through the ECO 4 Grant. Here are the key details regarding eligibility:

The Scottish Government’s ECO4 program is an integral part of the broader Free Boiler Scheme, aimed at combating fuel poverty. The program is designed to help those most in need, particularly pensioners and low-income families, by providing efficient and modern heating systems.

Who Qualifies For The Free Boiler Scheme?

For over a decade, the governments of the UK and Scotland have provided assistance for energy-saving home improvements. The ECO4 boiler scheme’s criteria include:

  • A household income of less than £19,720 per year.
  • Ownership of the property.
  • Receipt of specific benefits, including Child Benefits or Income Support.
  • Pensioners over 60 receiving Pension Credit Benefits.
  • Having a gas boiler older than 15 years.

A boiler with an EPC rating of D or lower, or one that is not functioning correctly.

What is
The ECO4 Scheme?

Launched in April 2022 and set to continue until March 2026, the Energy Company Obligation 4 (ECO4) scheme focuses on enhancing energy efficiency in UK homes. It aims to reduce carbon emissions and help the UK achieve its carbon neutrality goal by 2050.

Since 2012, over 2.3 million homes have benefited from this initiative, showcasing its broad impac

What does the ECO4 scheme cover?

The scheme extends to:

  • Free boiler installations
  • Comprehensive central heating systems
  • Boiler replacement services
  • Integration of renewable energy solutions such as solar panels and air source heat pumps

A range of insulation grants covering lofts, underfloors, walls, and roofs

What boilers can you get under the Free Boiler grant?

Homeowners can choose from:

    • Conventional boilers
    • Combination (combi) boilers
    • System boilers
    • Air-source heat pumps

Which Types Of Boilers
Are Not Eco-Friendly?

Gas boilers

  • Environmental impact: Gas boilers are one of the most popular types of boilers used in the local market as they utilise minimum levels of electricity. Regardless of this, gas boilers are not climate-friendly options. This is because they rely on natural gas, a fossil fuel, which, when burned, releases carbon dioxide (CO2) and other greenhouse gases into the atmosphere.
  • Efficiency: Older models of gas boilers are marked with a G-grade energy performance certification and offer a modest energy efficiency of approximately 70%. In contrast, modern iterations of gas boilers show enhanced efficiency but still do not match the superior energy efficiency rates attainable by combi boilers and heat pumps.
  • Regulatory changes: With the global trend moving towards sustainable energy sources, providers of gas boiler services are now bound by strict regulatory standards, including the requirement for an efficiency rating of 86% or higher. This shift in regulations could potentially lead to the gradual phasing out of gas boilers in the upcoming years.

Back boilers

  • Environmental Impact: Back boilers, once popular in the 60s and 70s, now lag significantly behind in efficiency, offering only about 78% compared to the over 90% efficiency of modern boilers like combi boilers. Not only do they emit higher levels of pollutants, typically being installed behind fireplaces, but they also pose a risk of carbon monoxide poisoning in case of leaks.

  • Outdated: The availability of parts for back boilers has become scarce due to their inefficiency and ongoing phase-out. This scarcity renders them impractical for sustained use in the long term.

  • Regulatory Changes: With the introduction of legal requirements for boilers to have at least an 86% efficiency rating, back boilers have become non-viable options, effectively being phased out of use.

Oil boilers

  • Environmental Impact: Oil boilers, which operate on heating oil, a fossil fuel, are significant contributors to environmental concerns. Their combustion process emits a substantial amount of CO2 and sulfur dioxide into the atmosphere, thereby exacerbating air pollution and increasing greenhouse gas emissions.

  • Efficiency: Traditional oil boilers, particularly those lacking condensing technology, typically operate at an efficiency range of 60-70%. Modern versions of these boilers have seen significant improvements, now achieving efficiency rates over 90%. However, despite these advancements, oil boilers are still less eco-friendly compared to other contemporary heating systems.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

The combination boiler, commonly known as a combi boiler, is an all-in-one efficient heating and central heating system.

These boilers directly warm water from the main supply, removing the necessity for an additional water tank. Their high energy efficiency and compact design make them ideal for homes with limited space.

Key characteristics of combi boilers are:

  • Compact design for space conservation
  • High energy efficiency
  • Instant hot water provision
  • Ease of installation and minimal maintenance needs



Heat Pumps

It’s important to understand that heat pumps are distinct from boilers; they neither create heat nor rely on burning fossil fuels.

Heat pumps function by shifting heat from one location to another, compatible with various heating distribution systems such as ducts, radiators, and underfloor systems. They can move heat into a building for warming purposes or out of it for cooling.

Operating primarily on electricity, heat pumps can also harness energy from renewable sources like solar or wind power, enhancing their energy efficiency and environmental friendliness for both heating and cooling.

Key attributes of heat pumps:

  • Zoning capabilities in some models allow for independent temperature control in different areas of a home.
  • Compatibility with existing heating systems, enhancing their efficiency.

Heat pump varieties for central heating:

  • Air-source heat pumps: These common units exchange heat between indoor and outdoor environments and are relatively straightforward and cost-effective to install.
  • Ground-source heat pumps: Utilizing the consistent underground temperature, these are more efficient but involve higher installation complexity and cost

What Are The Advantages Of An Eco-Friendly Combi Boiler?


This grant is a component of the ECO program, which allocates funds to households that satisfy specific eligibility requirements. Under this scheme, qualifying homes can access various energy-efficient solutions, such as complimentary boiler installations or replacements, central heating systems, solar panels, and heat pump units.

Combi boilers come with their own set of advantages, yet it’s important to be aware of some limitations before opting for an installation. A significant challenge they face is managing simultaneous high water usage within a household. For example, if multiple showers are used concurrently in different bathrooms, there could be a noticeable reduction in water pressure.

This happens because, unlike traditional boilers, combi boilers lack an additional tank to handle such peak water usage situations.

Qualifying for the Free Boiler grant typically requires the receipt of certain benefits, but this is not the only pathway to eligibility. Even without benefits, you might still meet the criteria. Envirohomes Renewables is equipped to assist in determining your eligibility for the ECO4 scheme’s free boiler offer, regardless of your benefits status.
