The Free Boiler Scheme, also known as the Free Boiler Replacement Scheme, is an integral part of the government-funded ECO4 programme. Its primary objective is to combat fuel poverty, particularly among pensioners and lower-income households, by upgrading heating systems and installing new boilers.

Who Qualifies For The Free Boiler Scheme?

For more than a decade, both the UK and Scottish governments have extended a helping hand by offering free boiler grants and financial aid to alleviate the energy burden on households. The Free Boiler grant, which operates within the framework of the ECO4 boiler scheme, has a mission to deliver a range of energy-saving enhancements to households across the UK. To qualify for this grant, specific eligibility criteria must be met:

  • Household income must not exceed £19,720 per annum.
  • You must own your home.
  • Receipt of benefits, including Child Benefits and Income Support, is required.
  • Pensioners aged over 60 who receive Pension Credit Benefits or similar support are eligible.
  • The current gas boiler in your possession should be over 15 years old.
  • Your boiler must have an Energy Performance Certificate (EPC) rating of D or lower.
  • Your boiler should be either broken or faulty.

What is
The ECO4 Scheme?

The Energy Company Obligation 4 (ECO4) scheme is the latest government initiative aimed at improving energy efficiency in homes throughout the UK. Launched in April 2022, it is the fourth installment in a series of government schemes dating back to 2013, with the ECO3 scheme concluding in March 2022. ECO4 is set to run until March 2026.

ECO4 takes a comprehensive approach to energy efficiency, with a primary focus on upgrading heating systems in UK homes. While it doesn’t provide direct heating assistance, its goal is to reduce carbon emissions, aligning with the UK’s target of achieving carbon neutrality by 2050.

Since the inception of the ECO scheme in 2012, over 2.3 million homes have benefited from improved energy efficiency standards. The scheme places significant responsibility on major energy companies to support low-income households, including:

  • Offering hardship grants to single parents.
  • Assisting people with disabilities.
  • Supporting financially struggling families.

Organizations like UK Energy Support work closely with Ofgem, the UK’s energy regulator, and other energy suppliers to ensure compliance with ECO scheme standards. Local authorities play a vital role in referring eligible households to the program.

What does the ECO4 scheme cover?

The ECO4 scheme provides financial support that encompasses a wide range of energy efficiency improvements for UK homes, including:

  • Free boilers
  • Central heating systems
  • Boiler replacement
  • Solar panels
  • Air source heat pumps
  • 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 a common choice for their minimal electricity consumption. However, they are among the least eco-friendly options because they rely on natural gas, a fossil fuel that emits carbon dioxide (CO2) and other greenhouse gases when burned.
  • Efficiency: Older gas boilers typically have a G-grade Energy Performance Certificate (EPC) rating with only 70% energy efficiency. Although modern gas boilers are becoming more efficient, they still fall short of the efficiency levels achieved by combi boilers or heat pumps.
  • Regulatory Changes: Due to environmental concerns, gas boilers face stringent regulations, including a requirement for 86% or higher efficiency ratings. This may lead to the phasing out of gas boilers in the near future.

Back boilers

  • Environmental impact: Back boilers are often outdated and highly inefficient, with an efficiency rating of around 78%. In contrast to modern alternatives like combi boilers (over 90% efficiency), these older models produce higher emissions, particularly when installed behind fireplaces. Additionally, leaks can lead to carbon monoxide poisoning.

  • Outdated: Due to their inefficiency and phased-out status, finding parts for back boilers can be challenging, making them unsustainable for long-term use.

  • Regulatory Changes: The installation of new boilers is subject to government regulations mandating an 86% efficiency rating, rendering back boilers obsolete.

Oil boilers

  • Environmental impact: Oil boilers operate using heating oil, which is classified as a fossil fuel. This process of heating releases a substantial amount of CO2 and sulfur dioxide into the atmosphere, contributing significantly to air pollution and greenhouse gas emissions.

  • Efficiency: Older non-condensing oil boilers generally achieve efficiency rates ranging from 60% to 70%. In contrast, modern versions of oil boilers have made significant advancements, boasting efficiencies exceeding 90%. Despite these improvements, it’s important to note that oil boilers still fall short in terms of eco-friendliness compared to other heating alternatives.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combi boiler, which is short for a combination boiler, represents a highly proficient heating unit that serves the dual function of a central heating system. Combi boilers excel in heating water directly from the mains, eliminating the necessity for a separate water storage tank. Their compact dimensions are especially advantageous for residences with limited space. Prominent characteristics of combi boilers encompass:

  • Efficient utilization of space due to their compact size.
  • Remarkable energy efficiency, ensuring optimal heating performance.
  • Immediate access to hot water on demand.
  • Simplified installation and reduced maintenance requirements.

Heat Pumps

It’s essential to note that heat pumps are not boilers, as they do not generate heat or rely on fossil fuels. Instead, they are devices designed to transfer heat from one location to another. Heat pumps work seamlessly with various distribution systems, such as ductwork, radiators, or underfloor heating, for both heating and cooling purposes.

Heat pumps typically operate using electricity but can be powered by renewable energy sources like solar panels or wind power. This versatility makes them highly energy-efficient and environmentally friendly in the long run.

Additional notable features of heat pumps include:

  • Zoning capabilities, allowing independent temperature control in different areas of your home.
  • Integration into existing central heating systems to enhance overall efficiency.

Two primary types of heat pump systems are commonly used for central heating:

  1. Air-source pumps: These are the most prevalent types of heat pumps, transferring heat between indoor and outdoor air. They are generally easier and less expensive to install.
  2. Ground-source pumps: These systems utilize the stable ground temperature as a heat source, providing higher efficiency but requiring a more complex and costly installation process.

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


The grant is categorized under the ECO scheme, a program that offers financial assistance to households that meet specific criteria. Through the ECO scheme, eligible households can access funding to qualify for various energy-saving upgrades, including complimentary boiler installations or replacements, central heating systems, free solar panels, heat pumps, and more.

Combi boilers offer numerous advantages, but it’s essential to be aware of certain limitations before deciding to install one in your home.

One primary concern is their performance under high water demand scenarios. For instance, if two individuals are simultaneously using showers in separate bathrooms, you might experience a reduction in water pressure. This occurs because combi boilers lack a backup tank, unlike conventional boilers, which can accommodate surges in water demand.

Meeting the criteria for receiving benefits is a significant factor in qualifying for the Free Boiler grant. However, even if you are not currently receiving benefits, there is still a possibility of eligibility. Envirohomes Renewables can assist you in determining whether you meet the requirements to receive a free boiler under the ECO4 scheme, regardless of your benefits status
