Who Qualifies For The Free Boiler Scheme?

Since more than ten years, the UK and Scottish government have combined forces to supply free boiler subsidies and economic help to facilitate home energy improvements.

This very objective launched the ECO4 boiler scheme, operating under the Free Boiler Scheme umbrella, that endeavors to improve energy efficiency and minimize heating costs. Following is the eligibility criteria:

  • A household income below £19,720 per year.
  • Homeownership status.
  • Receipt of certain benefits, including Child Benefits and Income Support.
  • Pensioners over 60 receiving Pension Credit Benefits.
  • Boilers older than 15 years or with an Energy Performance Certificate (EPC) rating of D or lower.
  • Malfunctioning or inefficient existing boilers.

What is
The ECO4 Scheme?

The Energy Company Obligation 4 (ECO4) scheme, launched in April 2022, represents the latest government effort to improve home energy efficiency in the UK. This scheme, intended to run until March 2026, focuses on upgrading heating systems, thereby reducing carbon emissions and aiding the UK in achieving its 2050 carbon neutrality goals.

Over 2.3 million homes have benefited from the scheme since its inception in 2012.

The scheme’s primary legislation is designed to hold large energy companies accountable for supporting low-income households, including:

  • Offering hardship grants to single parents
  • People with disabilities
  • Financially struggling families

Entities such as the UK Energy Support work alongside with Ofgem – the UK’s energy regulator – and other energy providers to ensure the standards of the ECO scheme are met.

Local authorities are essential in referring eligible households that would benefit from this scheme.

What does the ECO4 scheme cover?

The ECO4 scheme extends its support to a variety of energy-efficient home improvements, such as:

  • No-cost boiler installations.
  • Upgrades to central heating systems.
  • Boiler replacements.
  • Installation of solar panels and air source heat pumps.
  • A variety of insulation grants (loft, underfloor, external wall, etc.).

What boilers can you get under the Free Boiler grant?

The scheme supports the installation of various boiler types, including:

    • Conventional boilers.
    • Combination (Combi) boilers.
    • System boilers.
    • Air-source heat pumps.

Which Types Of Boilers
Are Not Eco-Friendly?

Gas boilers

  • Environmental impact: Gas boilers, a prevalent choice due to their minimal electricity usage, are facing criticism for their environmental impact. They operate by burning natural gas, a fossil fuel, leading to significant emissions of carbon dioxide (CO2) and other greenhouse gases. This aspect marks them as one of the less eco-friendly options in the boiler market.
  • Efficiency Challenges with Gas Boilers: The efficiency of gas boilers varies significantly depending on their age. Older models typically have a G-grade Energy Performance Certificate (EPC) rating, reflecting a mere 70% energy efficiency. In contrast, modern gas boilers have improved efficiency but still lag behind the performance levels of combi boilers or heat pumps.
  • Regulatory Changes Impacting Gas Boilers: Gas boilers are increasingly subject to stringent environmental regulations due to their ecological footprint. Current standards mandate an efficiency rating of 86% or higher. These evolving regulations point towards a potential gradual phase-out of gas boilers, as the industry moves towards more sustainable heating solutions.


Back boilers

  • Environmental Considerations: Back boilers, typically from older generations, exhibit lower efficiency (around 78%) compared to contemporary models like combi boilers, which boast efficiencies above 90%. Popular in the 1960s and 70s, these boilers are now less environmentally friendly due to higher emission levels. They also pose a risk of carbon monoxide leakage, especially when installed behind fireplaces.

    Obsolescence and Scarcity of Parts: The declining efficiency and gradual phase-out of back boilers have led to a scarcity of replacement parts. This makes their maintenance and long-term viability increasingly challenging.

    Compliance with Modern Standards: Current government regulations mandate a minimum efficiency of 86% for new boiler installations. This requirement renders back boilers incompatible with modern standards, effectively making them obsolete in contemporary settings.

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, is a dual-purpose unit that serves as both a highly efficient heater and a central heating system.

These boilers directly heat water from the mains, negating the requirement for a separate water storage unit. Their energy efficiency and compact design make them ideal for smaller residences.

Key characteristics of combi boilers encompass:

  • Compact design, offering space efficiency
  • High energy efficiency
  • Provision of instant hot water
  • Ease of installation and reduced maintenance needs

Heat Pumps

Heat pumps are distinct from boilers, primarily because they don’t create heat or utilize fossil fuels.

Heat pumps are systems that shift heat from one place to another, effectively with various heating distribution systems such as ductwork, radiators, or underfloor heating. They can transfer heat from outdoors to indoors for heating purposes, or the opposite for cooling.

These pumps are typically powered by electricity, but they can also operate using renewable energy sources like solar panels or wind turbines. This contributes to their high energy efficiency for both heating and cooling, and enhances their long-term environmental friendliness.

Additional features of heat pumps:

  • Zoning capability: Certain heat pump models allow for the independent temperature control of different areas within a home.
  • Integration with existing heating systems: This enhances the overall efficiency of the heating system.

Types of heat pump systems used in central heating include:

  • Air-Source Pumps: These are prevalent and function by transferring heat between the air inside and outside a building. They are generally more straightforward and less costly to install.
  • Ground-Source Pumps: These systems harness the earth’s consistent temperature for heat. While more efficient, they are also more costly and complex to install.

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.
