We specialize in providing fully funded boiler installation services for low-income households, courtesy of the Government’s ECO 4 Grant. The details regarding eligibility are outlined below, ensuring support for those most in need.

Under the government’s ECO4 programme, the ‘Free Boiler Scheme’ or ‘Free Boiler Replacement Scheme’ in Scotland aims to alleviate fuel poverty. This is particularly beneficial for pensioners and lower-income homes, offering upgraded heating systems and new boiler installations.

Who Qualifies For The Free Boiler Scheme?

For over a decade, the UK and Scottish governments have been committed to offering free boiler grants and financial support for home energy improvements. The ECO4 boiler scheme’s Free Boiler grant is designed to provide energy-saving enhancements to eligible UK households. Criteria for free boilers or boiler replacements include:

  • Household income less than £19,720 per annum.
  • Homeownership status.
  • Benefit recipients such as Child Benefits and Income Support.
  • Pensioners over 60 with Pension Credit Benefits.
  • Gas boilers older than 15 years.
  • Boilers with an EPC rating of D or lower.
  • Broken or faulty boilers.

What is
The ECO4 Scheme?

The Energy Company Obligation 4 (ECO4) scheme represents the latest stride by the UK government to promote energy efficiency in residential spaces across the country.

Initiated in April 2022, ECO4 marks the continuation of a series of governmental energy initiatives, starting from 2013. This follows the completion of the ECO3 scheme in March 2022 and is set to continue until March 2026.

ECO4 adopts a holistic approach towards energy efficiency, primarily focusing on the modernization of heating systems in UK homes. While its direct goal isn’t to provide heating, the scheme plays a significant role in cutting down carbon emissions, aligning with the UK’s objective to achieve carbon neutrality by 2050.

Since the ECO scheme’s inception in 2012, it has positively impacted over 2.3 million homes by elevating their energy efficiency.

A fundamental aspect of ECO4 is its legislative framework, which compels major energy corporations to support households facing financial hardships, including:

  • Providing assistance to single parents.
  • Supporting individuals with disabilities.
  • Aiding families in financial distress.

Organizations like UK Energy Support collaborate closely with Ofgem, the UK’s energy regulator, and various energy suppliers to uphold the ECO scheme’s standards. Local governments also play a crucial role in identifying and referring households that stand to benefit from the scheme.

What does the ECO4 scheme cover?

The ECO4 scheme offers financial support that covers a wide range of energy efficiency improvements for UK homes, such as:

  • Free boilers
  • Central heating systems
  • Boiler replacement
  • Solar panels
  • Air source heat pump
  • Storage heaters
  • Various types of insulation grants (e.g. loft, underfloor, external and internal wall, cavity wall, and roof insulation)

What boilers can you get under the Free Boiler grant?

  • Conventional boilers
  • Combi boilers
  • System boilers
  • Air-source heat pumps

Which Types Of Boilers
Are Not Eco-Friendly?

Gas boilers

  • Environmental Impact: While gas boilers are prevalent due to their low electricity consumption, they rank low in terms of environmental friendliness. This is primarily because they utilize natural gas, a fossil fuel. The combustion of natural gas results in the release of carbon dioxide (CO2) and other greenhouse gases, contributing to environmental pollution.

  • Efficiency Analysis: The efficiency of gas boilers varies with their age. Older models typically have a G-grade Energy Performance Certificate (EPC) rating, reflecting only about 70% energy efficiency. In contrast, newer gas boiler models show improved efficiency but still fall short of the efficiency achieved by combi boilers or heat pumps.

  • Regulatory Trends: Environmental considerations have led to stricter regulations for gas boilers. These include requirements for an efficiency rating of 86% or higher. Such regulatory changes suggest that gas boilers might be gradually phased out in the near future in favor of more eco-friendly heating options.

Back boilers

  • Environmental Impact: Back boilers, typically older models, are markedly less efficient (around 78%) compared to newer options like combi boilers, which often exceed 90% efficiency. Widely used in the 60s and 70s, back boilers are known for higher emission levels, especially since many were installed behind fireplaces. A significant risk associated with these boilers is the potential for carbon monoxide leakage if they malfunction.

    Obsolescence Issues: The scarcity of replacement parts for back boilers is a consequence of both their inefficiency and gradual discontinuation in the market. This makes them an impractical choice for long-term usage, as maintaining them becomes increasingly difficult.

    Regulatory Developments: Contemporary government regulations mandate that new boilers must achieve at least an 86% efficiency rating. This requirement renders back boilers obsolete, as they fail to meet the current energy efficiency standards, leading to their phasing out in favor of more efficient heating systems


Oil boilers

  • Environmental Impact: Operating on heating oil, a type of fossil fuel, oil boilers contribute to significant environmental concerns. The process of heating with oil leads to the substantial emission of carbon dioxide (CO2) and sulfur dioxide, both of which add to air pollution and the increase of greenhouse gases in the atmosphere.

  • Efficiency: In terms of efficiency, there is a stark contrast between older and newer models of oil boilers. Older, non-condensing oil boilers typically have efficiency rates ranging from 60-70%. However, more modern versions have shown improvements, with efficiency rates exceeding 90%. Despite this progress, oil boilers still do not match the eco-friendliness of alternative heating solutions.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combi boiler, short for combination boiler, serves as both a highly efficient heating unit and a central heating system in a single package.

Designed to heat water directly from the mains, combi boilers do away with the requirement for a separate water storage tank. Their high energy efficiency and compact size make them particularly suitable for smaller homes.

Key characteristics of combi boilers are:

  • Compactness, offering space-saving benefits
  • High energy efficiency
  • Provision of instant, on-demand hot water
  • Ease of installation and minimal maintenance needs

Heat Pumps

It’s important to understand that a heat pump is distinct from a boiler; it does not create heat nor does it rely on fossil fuels.

Rather, heat pumps are mechanisms that relocate heat from one location to another. They are compatible with a variety of heat distribution systems, including ducts, radiators, and underfloor heating. For instance, they can move heat from outdoors to indoors for heating, and the reverse for cooling.

Heat pumps generally operate on electricity, but can also be powered by renewable energy sources like solar panels or wind turbines. This makes them exceptionally energy-efficient for both heating and cooling, and more eco-friendly over time.

Additional features of heat pumps:

  • Zoning capabilities: Certain heat pump models offer zoning, allowing independent temperature control in different areas of a home.
  • Integration with existing heating systems: They can be combined with current central heating systems to enhance efficiency.
  • Types of heat pumps for central heating:
    • Air-source heat pumps: These common types transfer heat between indoor and outdoor air and are usually easier and cheaper to install.
    • Ground-source heat pumps: Utilizing the consistent temperature of the earth, these are more efficient but require a more complex and costly installation

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


The Free Boiler Grant is a part of the broader ECO4 scheme, offering funding for eligible households to acquire free boilers or boiler replacements, central heating systems, and more.

While combi boilers are beneficial, they may struggle with high water demand, such as simultaneous showers, due to the lack of a backup tank.

While receiving benefits is a key criterion, eligibility for the Free Boiler grant is not exclusively limited to benefit recipients. Envirohomes Renewables can assist in assessing your eligibility under the ECO4 scheme.
