Recognizing the challenges faced by low-income households in managing energy costs, Envirohomes Renewables offers a unique solution. Our boiler installation service, funded through the Government’s ECO 4 Grant, is specially designed to support these households.

This program aligns with our ethos of making energy efficiency accessible to all. We meticulously assess each case to ensure eligible homes receive the support they need, detailed in the criteria below.

Who Qualifies For The Free Boiler Scheme?

This scheme, integral to Scotland’s energy efficiency strategy, falls under the ECO4 programme funded by the government. It targets fuel poverty, a prevalent issue among pensioners and low-income families in Scotland. The scheme is a game-changer, offering upgrades to heating systems and new, more efficient boilers at no cost to eligible households. It’s not just about providing warmth; it’s about equipping homes for a more sustainable future.

The Free Boiler grant, a key element of the ECO4 scheme, is designed with inclusivity in mind. To qualify, applicants must meet certain criteria: a household income of less than £19,720 per annum, homeownership status, receipt of specific benefits (like Child Benefits and Income Support), or being a pensioner over 60 receiving Pension Credit Benefits. The condition of the existing boiler is also considered, with eligibility extended to those with boilers over 15 years old, those rated D or lower in energy performance, or those that are broken or faulty.

What is
The ECO4 Scheme?

The ECO4 scheme, initiated in April 2022, is the government’s latest step towards improving home energy efficiency across the UK.

This scheme, the fourth of its kind, is part of a long-term initiative that began in 2013. Scheduled to run until March 2026, it is a crucial element in the UK’s strategy to achieve its carbon-neutral goals by 2050. Since its inception, the ECO scheme has made a significant impact, benefiting over 2.3 million homes.

Envirohomes Renewables has been at the forefront of this effort, bringing energy-efficient solutions to homes across Scotland.

ECO4 extends its financial support to a range of energy efficiency improvements, including but not limited to free boilers, upgraded central heating systems, boiler replacements, solar panels, and air source heat pumps. It also covers various insulation grants such as loft, underfloor, external and internal wall, cavity wall, and roof insulation.

This comprehensive support ensures that homes not only become more energy-efficient but also contribute to a reduction in overall carbon emissions.

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: Gas boilers are commonly used due to their low electricity needs. However, they are environmentally detrimental as they burn natural gas, releasing carbon dioxide and other greenhouse gases.

    Efficiency of Gas Boilers: Old gas boilers have a low efficiency of about 70% (G-grade EPC rating), whereas modern ones are more efficient but still lag behind combi boilers and heat pumps.

    Regulations for Gas Boilers: Stringent regulations require gas boilers to have at least an 86% efficiency rating. This, along with environmental concerns, might lead to their phase-out in favor of greener alternatives.

Back boilers

  • Environmental Impact: Back boilers, typically relics from the 1960s and 1970s, offer a mere 78% efficiency, significantly lower than modern combi boilers, which exceed 90%. Besides being less efficient, they also emit more pollutants and carry a risk of carbon monoxide leakage due to their age and design.

    Outdated: These boilers are increasingly obsolete, challenged by inefficiencies and a dwindling supply of replacement parts. Their decline in popularity and use makes maintaining them less viable for long-term household heating solutions.

    Regulatory Changes: Due to environmental considerations, new regulations require boilers to have at least an 86% efficiency rating. This shift has made back boilers, which fall short of these standards, effectively redundant in modern installations.

Oil boilers

  • Environmental Impact: Oil boilers, powered by heating oil, contribute notably to environmental degradation. Their operation leads to high emissions of CO2 and sulfur dioxide, exacerbating air pollution and adding to the problem of greenhouse gas emissions.

    Efficiency: Traditional oil boilers, particularly the older non-condensing types, show limited efficiency, hovering around 60-70%. This is considerably lower compared to the more than 90% efficiency achieved by modern heating systems, highlighting the ecological shortcomings of oil boilers.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combi boiler, or combination boiler, serves as both a high-efficiency heating unit and a central heating system, offering a dual-purpose solution in a single compact unit.

These boilers directly heat water from the mains supply, eliminating the need for a separate water tank. This not only saves space but also ensures energy-efficient operation, making them a suitable choice for smaller homes.

Key features of combi boilers include their compact size for space-saving, high energy efficiency, provision of instant hot water, and relatively simple installation and maintenance requirements.

Heat Pumps

Heat pumps differ fundamentally from boilers; they don’t produce heat nor rely on fossil fuels. Rather, their primary function is to relocate heat from one area to another. This makes them adaptable to various heating systems like ductwork, radiators, or underfloor heating, efficiently moving heat in or out of a building for heating and cooling purposes.

Operation and Efficiency of Heat Pumps

Operating typically on electricity, heat pumps can also harness renewable energy sources such as solar or wind power, enhancing their energy efficiency and environmental friendliness. They are versatile for both heating and cooling, offering a sustainable alternative to traditional heating systems.

Features and Types of Heat Pump Systems

Heat pumps offer the advantage of zoning capabilities, allowing independent temperature control in different parts of a house. They can also be integrated into existing heating systems for improved efficiency.

  • Air-source Heat Pumps: Common and user-friendly, these pumps exchange heat between indoor and outdoor environments. They are known for their easier and more cost-effective installation.

  • Ground-source Heat Pumps: Utilizing the earth’s consistent underground temperature, these pumps are highly efficient but involve a higher initial investment and more complex installation processes.

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.
