Understanding the unique challenges faced by low-income households, our services are specially crafted to provide fully funded boiler installation through the Government’s ECO 4 Grant. The eligibility criteria are detailed below.

 The Free Boiler Scheme, a part of the ECO4 programme funded by the government, is a significant step toward combating fuel poverty, particularly for pensioners and lower-income homes. This scheme is not just about installing new boilers but upgrading existing heating systems to be more energy-efficient.

Who Qualifies For The Free Boiler Scheme?

For over a decade, the Scottish and UK governments have been steadfast in their commitment to providing energy relief through free boiler grants. The ECO4 boiler scheme in the Isle of Skye is designed to offer a range of energy-saving improvements. Key eligibility criteria include:

  • An annual household income less than £19,720.
  • Homeownership status.
  • Receipt of certain benefits, including Child Benefits and Income Support.
  • Pensioners over 60 receiving Pension Credit Benefits.
  • Homes with gas boilers older than 15 years or with an EPC rating of D or lower.
  • Residences with broken or faulty boilers.

What is
The ECO4 Scheme?

The Energy Company Obligation 4 (ECO4) scheme is the latest government initiative launched in April 2022 and is set to continue until March 2026. This scheme is the fourth in a series of government efforts that began in 2013, following the conclusion of the ECO3 scheme in March 2022.

The ECO4 scheme’s focus is not just on providing heating solutions but on significantly reducing carbon emissions to assist the UK in achieving carbon neutrality by 2050. Since the launch of the ECO scheme in 2012, more than 2.3 million homes have benefited from improved energy efficiency standards. The primary goal of this legislation is to hold large energy companies accountable for aiding low-income households, including:

  • Providing hardship grants to single parents.
  • Assisting individuals with disabilities.
  • Supporting financially struggling families.

Collaborations between organizations like UK Energy Support and Ofgem, alongside other energy suppliers, play a pivotal role in upholding the ECO scheme’s standards. Local authorities also have a crucial role in identifying and referring households that would benefit most 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 are a common choice due to their low electricity consumption for ignition. However, they are among the least environmentally friendly heating options. This is primarily because they utilize natural gas, a fossil fuel, whose combustion releases carbon dioxide (CO2) and other greenhouse gases, contributing to atmospheric pollution.
  • Efficiency: Older models of gas boilers typically have a G-grade Energy Performance Certificate (EPC) rating, indicating about 70% energy efficiency. Although newer models have improved in efficiency, they still do not match the higher efficiency levels of modern combi boilers or heat pumps.
  • Regulatory Changes: In light of environmental considerations, gas boilers are subject to stringent regulations, including the requirement for an efficiency rating of 86% or higher. Such regulations suggest that gas boilers may gradually be phased out.

Back boilers

  • Environmental impact: Back boilers, generally older and less efficient at about 78%, are overshadowed by the more efficient modern boilers, like combi boilers, which exceed 90% efficiency. Popular in the 60s and 70s, back boilers are known for higher emission levels, especially those installed behind fireplaces. They also pose risks of carbon monoxide leakage.
  • Outdated Technology: The scarcity of replacement parts due to their inefficiency and gradual obsolescence renders back boilers less viable for long-term use.
  • Regulatory Changes: New installations must meet a minimum efficiency rating of 86%, as per government regulations, rendering back boilers obsolete.

Oil boilers

  • Environmental impact: Operating on heating oil, another fossil fuel, oil boilers contribute significantly to environmental pollution by releasing large amounts of CO2 and sulfur dioxide, exacerbating air pollution and greenhouse gas emissions.
  • Efficiency: Traditional, non-condensing oil boilers generally have efficiency rates between 60-70%. Although recent advancements have improved the efficiency of newer oil boiler models to over 90%, they still fall short in eco-friendliness compared to other heating system options.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combi boiler, short for combination boiler, is a highly efficient heating unit and central heating system rolled into one. It heats water directly from the mains, eliminating the need for a separate water storage tank. This makes it highly energy-efficient and particularly suitable for smaller homes. Notable features include:

  • Space-saving due to its smaller size.
  • High energy efficiency, reducing utility bills.
  • On-demand hot water provision.
  • Simpler installation and lower 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.
