Who Qualifies For The Free Boiler Scheme?

For over ten years, the Scottish and UK Governments have been committed to fostering sustainable living by providing free boiler grants. The ECO4 scheme, active in Shetland, plays a crucial role in this mission by offering free boilers or replacements to qualifying households. This initiative aims to lower heating expenses and enhance energy efficiency. Criteria for eligibility under this scheme are:

  • Annual household income must be below £19,720.
  • The applicant must own their home.
  • Eligibility extends to individuals receiving specific benefits such as Child Benefits or Income Support.
  • Pensioners aged over 60 and in receipt of Pension Credit Benefits are eligible.
  • The scheme is available for homes with boilers that are over 15 years old or have an EPC rating of D or lower.
  • It also covers households with malfunctioning boilers.

What is
The ECO4 Scheme?

The Energy Company Obligation 4 (ECO4) is the most recent initiative by the UK government to boost home energy efficiency nationwide.

Initiated in April 2022, the ECO4 scheme follows its predecessor, ECO3, which concluded in March 2022, and continues a series of energy efficiency efforts that began in 2013. This scheme is set to continue until March 2026.

ECO4 adopts a holistic approach to enhancing energy efficiency, primarily targeting the upgrade of heating systems in homes across the UK. The ultimate goal of the ECO scheme is not just to provide heating solutions but to also contribute to reducing carbon emissions, aiding the UK in achieving its target of carbon neutrality by 2050.

Since its inception in 2012, the ECO initiative has positively impacted over 2.3 million homes with enhanced energy efficiency standards.

Key objectives of the ECO4 scheme include obliging major energy companies to support households with lower incomes by:

  • Providing hardship grants specifically aimed at single parents.
  • Assisting individuals with disabilities.
  • Aiding families facing financial difficulties.

Organizations such as UK Energy Support collaborate closely with Ofgem, the UK’s energy regulatory body, and various energy suppliers to uphold the ECO scheme’s standards. Local authorities play a crucial role in identifying and referring households that are eligible and would benefit from this scheme.

What does the ECO4 scheme cover?

The ECO4 scheme offers extensive assistance for various energy efficiency enhancements in Shetland homes, including:

  • Providing free boiler installations.
  • Upgrading central heating systems.
  • Installing solar panels.
  • Implementing air source heat pumps.
  • Installing storage heaters.
  • Offering various insulation grants (e.g., loft, wall, and floor insulation).

Each element of this scheme is aimed at not just elevating the energy efficiency of homes but also at decreasing overall energy usage and reducing greenhouse gas emissions.

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: Gas boilers, commonly used due to their low electricity requirements for starting, are among the less environmentally friendly heating options. Their reliance on natural gas, a type of fossil fuel, leads to the emission of carbon dioxide (CO2) and other greenhouse gases when the fuel is burned, contributing negatively to the environment.
  • Efficiency of Gas Boilers: In terms of energy efficiency, older models of gas boilers typically have a G-grade rating on the Energy Performance Certificate (EPC), indicating only about 70% efficiency. Although newer models of gas boilers have improved in efficiency, they still do not match the higher efficiency rates achieved by modern combi boilers or heat pumps.
  • Regulatory Shifts: Environmental concerns have led to the imposition of several regulations on gas boilers, demanding a minimum efficiency rating of 86% or more. These regulatory changes suggest a potential decline in the use of gas boilers in the foreseeable future.

Back boilers

  • Environmental impact: Back boilers are a stark contrast to the over 90% efficiency of contemporary combi boilers. Popular in the 1960s and 1970s, these boilers are notorious for higher emissions, especially when installed behind fireplaces. Moreover, there is a risk of carbon monoxide leakage with back boilers, which poses serious safety concerns.
  • Obsolescence of Back Boilers: The scarcity of replacement parts due to their inefficiency and gradual phase-out renders back boilers increasingly unsustainable for long-term use. This lack of availability and support contributes to their declining usability.
  • Regulatory Impact on Back Boilers: Under current government regulations, new boiler installations are required to have a minimum efficiency rating of 86%. This mandate effectively renders back boilers obsolete, as they fall short of meeting these modern efficiency standards.

Oil boilers

  • Environmental impact: Oil boilers, which use heating oil as a fuel source, have a notable environmental footprint. During operation, they emit a considerable amount of carbon dioxide (CO2) and sulfur dioxide, contributing to both air pollution and the increase in greenhouse gases in the atmosphere.
  • Efficiency of Oil Boilers: Regarding energy efficiency, traditional oil boilers, particularly the older non-condensing types, typically exhibit efficiency levels between 60-70%. While newer oil boiler models have seen improvements in efficiency, achieving over 90% in some cases, they still do not measure up in eco-friendliness compared to other heating systems.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combination boiler, commonly known as a combi boiler, serves as an all-in-one heating and central heating solution, renowned for its high efficiency.

These boilers directly heat water from the mains supply, removing the necessity for a separate water tank. Their design focuses on energy efficiency and compactness, making them a suitable option for smaller living spaces.

Key attributes of combi boilers are:

  • Compact design, offering space-saving advantages.
  • High energy efficiency, reducing utility costs.
  • Provision of instant hot water on demand.
  • Ease of installation and minimal maintenance needs.

Heat Pumps

It’s important to understand that heat pumps are distinctly different from boilers. Heat pumps do not produce heat by combustion, nor do they operate on fossil fuels.

Functioning as thermal transfer devices, heat pumps move heat from one location to another, making them versatile for integration with various heating distribution systems, such as ducts, radiators, or underfloor heating. For instance, they can extract heat from the exterior to warm the interior of a building, and can also reverse the process for cooling purposes.

Typically powered by electricity, heat pumps can also utilize renewable energy sources like solar or wind power. This aspect makes them highly efficient for both heating and cooling needs and enhances their environmental sustainability over time.

Additional characteristics of heat pumps include:

  • The capability for zoning in some models, allowing independent temperature control in different areas of a home.
  • Compatibility with existing central heating systems, which enhances their overall energy efficiency.

Regarding the types of heat pump systems available for central heating:

  • Air-source heat pumps are popular and function by exchanging heat between indoor and outdoor air. These systems are generally more cost-effective and simpler to install.
  • Ground-source heat pumps tap into the consistent underground temperatures to source heat. While they offer greater efficiency, they tend to be more costly and complex to install compared to air-source heat pumps.

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


The grant falls under the ECO scheme.

The ECO scheme provides funding to eligible households that meet the necessary criteria. This allows them to qualify for a free boiler/boiler replacement, central heating systems, free solar panels, heat pumps, etc.

While combi boilers provide many benefits, they do have a few downfalls that need to be considered before having one installed.

The most prominent issue is that these boilers can struggle when there is a high demand for water in a household at one time. If two people are showering in two different bathrooms at once, you may notice a decrease in water pressure. This is because a combi boiler does not have a backup tank, like a conventional boiler, to meet high water demands.

Benefits are one of the most important criteria to have in order to qualify for the Free Boiler grant; however, you may still be eligible if you do not receive any benefits. Envirohomes Renewables can easily help you figure out if you qualify to receive a free boiler under the ECO4 scheme, whether you receive benefits or not.
