We specialize in assisting low-income households in acquiring fully funded boiler installations through the Government’s ECO 4 Grant. The criteria for eligibility are outlined below. 

Under the ECO4 programme funded by the government, the Free Boiler Scheme in Scotland aims to combat fuel poverty, particularly among pensioners and lower-income households. The initiative involves upgrading heating systems or installing new boilers.

Who Qualifies For The Free Boiler Scheme?

The UK and Scottish governments have been providing free boiler grants and home energy assistance for over a decade. Eligibility for the Free Boiler grant under the ECO4 scheme is based on:

  • A household income below £19,720 per annum.
  • Homeownership status.
  • Receipt of certain benefits, including Child Benefits and Income Support.
  • Being a pensioner (over 60) receiving Pension Credit Benefits or similar.
  • Owning a gas boiler older than 15 years.
  • Possessing a boiler with an EPC rating of D or lower.
  • Having a broken or faulty boiler.

What is
The ECO4 Scheme?

Initiated in April 2022, ECO4 marks the fourth phase of a series of governmental efforts starting in 2013, following the conclusion of the ECO3 scheme in March 2022.

Scheduled to continue until March 2026, ECO4 adopts an extensive strategy aimed at enhancing energy efficiency, with a key focus on the modernization of heating systems in UK residences. The primary goal of the ECO initiative is not just to increase warmth but also to contribute to the reduction of carbon emissions, aligning with the UK’s ambition to achieve carbon neutrality by 2050.

Since its inception in 2012, the ECO program has positively impacted over 2.3 million households through elevated energy efficiency standards.

ECO4’s foundational legislation obliges major energy corporations to support low-income families, encompassing:

  • Provision of financial aid to single-parent families
  • Support for individuals with disabilities
  • Assistance to families facing economic hardships

Organizations such as UK Energy Support collaborate closely with Ofgem, the UK’s energy oversight body, and various energy providers to uphold the ECO program’s criteria. Local government bodies play a crucial role in identifying and referring households that would gain from this initiative

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: Widely used due to their low electricity requirements for ignition, gas boilers are, paradoxically, among the least environmentally friendly heating options. Their reliance on natural gas, a fossil fuel, results in the emission of carbon dioxide (CO2) and other greenhouse gases, contributing to environmental concerns.

  • Energy Efficiency: The energy efficiency of older gas boilers is notably low, with a G-grade Energy Performance Certificate (EPC) rating and just 70% efficiency. Despite improvements in newer models, they still fall short of the efficiency achieved by combi boilers or heat pumps.

  • Regulatory Challenges: In response to environmental concerns, gas boilers face stringent regulations, including the requirement to operate at an efficiency of 86% or higher. These evolving standards suggest a potential decline in the use of gas boilers in the coming years.

Back boilers

  • Environmental Considerations of Back Boilers: Traditionally a popular choice in the 60s and 70s, back boilers, typically installed behind fireplaces, are now recognized for their inefficiency. With an efficiency rate of only about 78%, they lag considerably behind modern boilers like combi models, which boast over 90% efficiency. These older back boilers not only have higher emission levels but also pose risks like carbon monoxide leakage if they malfunction.

    Issues with Obsolescence: The declining use and efficiency of back boilers have led to a scarcity of replacement parts. This scarcity, combined with their outdated technology, renders them unsustainable for long-term usage.

    Regulatory Impact on Back Boilers: Current government regulations stipulate a minimum efficiency of 86% for new boiler installations. This requirement effectively renders back boilers obsolete, as they fail to meet these efficiency standards.

Oil boilers

  • Environmental impact: Oil boilers operate on heating oil – another fossil fuel. The heating process releases a significant amount of CO2 and sulfur dioxide into the atmosphere, contributing to air pollution and greenhouse gas emissions.
  • Efficiency: Older, non-condensing oil boilers have efficiency rates of 60-70%. In comparison, modern versions have made strides in efficiency (with rates of over 90%), making oil boilers lacking in terms of eco-friendliness.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combination boiler, commonly known as a combi boiler, combines a high-efficiency heating unit with a central heating system.

These boilers directly heat water from the main supply, removing the necessity for a separate water tank. Their energy-efficient nature and smaller size make them especially suitable for smaller homes.

Key characteristics of combi boilers are:

  • Compact design, saving space
  • High energy efficiency
  • Instant hot water supply
  • Easier installation and reduced maintenance needs

Heat Pumps

It’s important to understand that heat pumps are distinct from boilers; they don’t produce heat nor do they rely on fossil fuels.

Heat pumps function by relocating heat from one place to another and are versatile enough to work with various heating distribution systems, including ductwork, radiators, and underfloor heating. They can move heat from outside to inside a building for heating purposes, or reverse the process for cooling.

Typically powered by electricity, heat pumps can also be connected to renewable energy sources like solar panels or wind turbines, enhancing their energy efficiency and environmental friendliness for both heating and cooling.

Key features of heat pumps include:

  • Zoning capabilities, allowing for independent temperature control in different areas of a home.
  • Compatibility with existing central heating systems to boost efficiency.

There are two main types of heat pumps for central heating:

  1. Air-Source Heat Pumps: These are prevalent and work by exchanging heat between the indoor environment and the outside air. They are generally more straightforward and cost-effective to install.
  2. Ground-Source Heat Pumps: These systems utilize the earth’s consistent temperature for heat exchange. While more efficient, they tend to be costlier and more complex to set up.

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


The Free Boiler Grant is part of the broader ECO scheme, providing financial aid to eligible households for energy-efficient upgrades like boilers, heating systems, and solar panels.

Combi boilers may struggle with high simultaneous water demands, leading to reduced water pressure. This is due to the absence of a backup tank.

While benefits are a key criterion, you may still be eligible for the Free Boiler grant. Envirohomes Renewables can help determine your eligibility under the ECO4 scheme, regardless of your benefits status.
