Who Qualifies For The Free Boiler Scheme?

For over ten years, both the UK and Scottish governments have been offering free boiler grants and financial support for home energy improvements across the UK. The Free Boiler grant under the ECO4 boiler scheme aims to provide a range of energy-saving upgrades to UK households. To be eligible, homeowners must meet certain criteria, including:

  • A household income less than £19,720 annually.
  • Homeownership status.
  • Receiving benefits like Child Benefits and Income Support.
  • Pensioners aged over 60 who receive Pension Credit Benefits or similar.
  • Owners of gas boilers older than 15 years.
  • Boilers with an EPC rating of D or lower.
  • Non-functional or faulty boilers.

What is
The ECO4 Scheme?

The Energy Company Obligation 4 (ECO4) scheme, initiated by the UK government in April 2022, represents the latest effort in a series of initiatives aimed at boosting home energy efficiency across the UK. This series began in 2013, with the previous ECO3 scheme concluding in March 2022.

Set to continue until March 2026, ECO4 adopts a holistic approach to enhancing energy efficiency, with a significant focus on modernizing home heating systems across the UK. The goal of the ECO scheme extends beyond just providing heating solutions; it is also geared towards reducing carbon emissions in support of the UK’s objective to achieve carbon neutrality by 2050.

Since its inception in 2012, the ECO scheme has positively impacted over 2.3 million homes, significantly improving their energy efficiency standards.

A key aspect of ECO4 is the accountability it places on major energy companies to support households with lower incomes. This includes providing hardship grants to single-parent families, assisting people with disabilities, and aiding families facing financial challenges. Organizations like UK Energy Support collaborate with Ofgem, the UK’s energy regulator, and other energy suppliers to ensure the standards of the ECO program are maintained. Local government bodies also play a crucial role in identifying and recommending households that stand to benefit the most from the scheme.

What does the ECO4 scheme cover?

The ECO4 scheme offers financial support covering a wide array of energy efficiency improvements for UK homes, such as:

  • Provision of free boilers
  • Upgrades to central heating systems
  • Boiler replacements
  • Installation of solar panels
  • Implementation of air source heat pumps
  • Installation of energy-efficient storage heaters
  • Various insulation grants (including loft, underfloor, 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, often selected for their low electricity requirement for ignition, fall behind in terms of environmental sustainability. Their operation, which involves the burning of natural gas, a fossil fuel, leads to significant atmospheric pollution. This is mainly due to the release of carbon dioxide (CO2) and other greenhouse gases, highlighting their detrimental environmental impact.
  • Efficiency Ratings: In terms of energy efficiency, older gas boiler models usually have a G-grade rating on the Energy Performance Certificate (EPC), equating to about 70% energy efficiency. Despite advancements in newer models, they still fail to reach the higher efficiency levels of modern combi boilers or heat pumps. This shortfall in efficiency is an important consideration for environmentally conscious choices in heating solutions.
  • Regulatory Outlook: Due to growing environmental concerns, gas boilers are now subject to stricter regulations, which require a minimum efficiency rating of 86% or higher. This change in regulations suggests a potential decline in the use of gas boilers in the future, as the market shifts towards more eco-friendly and efficient heating alternatives.

Back boilers

  • Environmental Impact Back boilers, primarily those from the 1960s and 1970s, demonstrate a significant gap in efficiency, averaging only 78%, compared to the over 90% efficiency found in modern combi boilers. Once popular, back boilers now raise environmental red flags due to their higher emissions, particularly in units installed behind fireplaces. Additionally, they carry the risk of carbon monoxide leaks, which pose serious safety hazards.

  • Outdated usage: The dwindling availability of replacement parts for back boilers, a consequence of their inefficiency and gradual discontinuation, has affected their long-term practicality. Their diminishing support and parts availability have made them increasingly unsuitable for sustained use.

  • Regulatory Challenges: With new governmental regulations mandating a minimum efficiency rating of 86% for boiler installations, back boilers fall short of meeting these updated efficiency standards. This regulatory change effectively marks the end of the line for back boilers, as they do not align with contemporary energy efficiency requirements.

Oil boilers

  • Environmental Impact:: Utilizing heating oil, a derivative of fossil fuels, oil boilers contribute significantly to environmental degradation. Their operation emits considerable amounts of carbon dioxide (CO2) and sulfur dioxide, exacerbating air pollution and amplifying greenhouse gas concentrations in the atmosphere. This underscores the substantial ecological impact of oil boilers.

  • Efficiency: When assessing efficiency, it’s noted that traditional, non-condensing oil boilers typically achieve efficiency levels ranging from 60-70%. Although technological advancements have enhanced the efficiency of newer oil boiler models – with some achieving upwards of 90% efficiency – they still fall short in eco-friendliness compared to newer, more advanced heating solutions.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combi boiler, short for combination boiler, is an all-in-one heating solution, efficiently providing both home heating and hot water from a single compact unit.

These boilers draw water directly from the mains, eliminating the necessity for a separate water tank. Notably efficient in terms of energy use, combi boilers are an ideal choice for smaller homes, thanks to their space-efficient design.

Significant advantages of combi boilers encompass:

  • Their small footprint, which is a boon for saving space in the home.
  • Enhanced energy efficiency leading to reduced energy bills.
  • The ability to supply hot water instantly and on demand.
  • Simplified installation and generally lower maintenance demands.

Heat Pumps

Understanding that heat pumps are distinct from boilers is crucial. Heat pumps do not generate heat through combustion nor do they use fossil fuels, unlike traditional boilers.

The working principle of heat pumps involves moving heat from one place to another. They are adaptable to various heating distribution methods such as ducts, radiators, or underfloor systems. For example, they can extract heat from the outside air to warm a building and can also function in reverse for cooling purposes.

Heat pumps are predominantly electrically powered and can be integrated with renewable energy sources like solar or wind power. This feature renders them highly energy-efficient for both heating and cooling, and more environmentally friendly in the long run.

Key attributes of heat pumps are:

  • The capability of some models to support zoning, which allows for different temperatures in distinct areas of a home.
  • Their compatibility with pre-existing central heating setups, thereby boosting overall system efficiency.

Exploring the Varieties of Heat Pump Systems:

  • Air-source heat pumps are common and work by exchanging heat between the interior and exterior air of a building. They are typically more budget-friendly and easier to install than other types.
  • Ground-source heat pumps harness the stable temperature beneath the earth’s surface to provide heat. Although they offer higher efficiency, these systems tend to be more expensive and complex to set up in comparison to air-source variants

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


The Free Boiler 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.
