Below, you’ll find detailed information on the eligibility requirements and how you can benefit from the “Free Boiler Scheme” in Scotland, which is part of the government-funded ECO4 initiative.

Who Qualifies For The Free Boiler Scheme?

For more than ten years, both the UK and Scottish governments have been dedicated to providing free boiler grants and financial support to alleviate the energy burden on households across the UK. The Free Boiler grant, operating under the ECO4 boiler scheme, aims to deliver various energy-saving improvements to eligible households. To qualify for this grant, specific eligibility criteria must be met:

  1. Household income of less than £19,720 per annum.
  2. Homeownership.
  3. Receipt of benefits (e.g., Child Benefits and Income Support).
  4. Pensioners (over 60 years old) who receive Pension Credit Benefits or similar support.
  5. Current gas boiler over 15 years old.
  6. Boiler with an Energy Performance Certificate (EPC) rating of D or lower.
  7. Broken or faulty boiler.

What is
The ECO4 Scheme?

Launched in April 2022, the Energy Company Obligation 4 (ECO4) scheme is the latest government policy aimed at enhancing energy efficiency in homes across the UK. This scheme represents the fourth installment in a series of government initiatives that commenced in 2013, following the conclusion of the ECO3 scheme in March 2022. The ECO4 scheme is set to continue until March 2026.

ECO4 adopts a comprehensive approach to energy efficiency, with a primary focus on upgrading heating systems in UK homes. Although its primary goal is not to provide warmth, the scheme is designed to reduce carbon emissions, thereby contributing to the UK’s carbon-neutral objectives 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’s core legislation holds major energy companies accountable for supporting low-income households, including offering hardship grants to single parents, individuals with disabilities, and financially struggling families. Companies like UK Energy Support collaborate closely with Ofgem, the UK’s energy regulator, and other energy suppliers to ensure compliance with ECO scheme standards. Local authorities play a crucial role in referring eligible households that stand to benefit 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: Gas boilers, although commonly used due to their minimal electricity requirements, are among the less eco-friendly options. They rely on natural gas, a fossil fuel that emits carbon dioxide (CO2) and other greenhouse gases when burned.
  • Efficiency: Older gas boilers have a G-grade EPC rating with only 70% energy efficiency. While modern gas boilers are becoming more efficient, they still lag behind the efficiency levels of combi boilers or heat pumps.
  • Regulatory Changes: Due to environmental concerns, gas boilers are subject to numerous regulations, including the requirement for an 86% or higher efficiency rating. This may result in the phasing out of gas boilers in the near future.

Back boilers

  • Environmental impact: Back boilers, often older models, are highly inefficient (78%) compared to modern alternatives like combi boilers (over 90%). These boilers emit higher levels of emissions and pose a risk of carbon monoxide poisoning if they leak.
  • Outdated: Back boilers face scarcity of parts due to inefficiency and phasing out, making them unsustainable for long-term use.
  • Regulatory Changes: Government regulations mandate an 86% efficiency rating for new boiler installations, rendering back boilers obsolete.

Oil boilers

  • Environmental impact: Oil boilers run on heating oil, another fossil fuel that releases significant CO2 and sulfur dioxide into the atmosphere during the heating process, contributing to air pollution and greenhouse gas emissions.
  • Efficiency: Older non-condensing oil boilers achieve efficiency rates of 60-70%, while modern versions have achieved rates of over 90%. This makes oil boilers less eco-friendly in comparison.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combi boiler, or combination boiler, is a highly efficient heating unit and central heating system rolled into one. Combi boilers heat water directly from the mains, eliminating the need for a separate water storage tank.

Key advantages of combi boilers include:

  • Space-saving design due to their compact size.
  • Exceptional energy efficiency.
  • On-demand hot water supply.
  • Simplified installation and lower maintenance requirements.

Heat Pumps

Heat pumps are distinct from boilers, as they do not generate heat or rely on fossil fuels. Instead, they transfer heat from one location to another. Heat pumps are versatile and can integrate with various distribution systems such as ductwork, radiators, or underfloor heating for both heating and cooling purposes. Notable features of heat pumps include:

  • Ability to operate on electricity, renewable systems like solar panels or wind power, making them energy-efficient and environmentally friendly.
  • Zoning capabilities for temperature control in different areas of the house.
  • Integration into existing central heating systems for improved overall efficiency.

Types of heat pump systems for central heating include:

  • Air-source pumps: These are the most common types, transferring heat between indoor and outdoor air. They are generally easier and less expensive to install.
  • Ground-source pumps: These use the stable temperature of the ground as a heat source, offering higher efficiency but being more expensive and complex to install.

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, allowing them to qualify for a free boiler/boiler replacement, central heating systems, free solar panels, heat pumps, and more.

While combi boilers offer numerous benefits, they do have certain drawbacks to consider.

The most notable issue is that combi boilers can struggle when there is a high demand for water in a household simultaneously. For instance, if two people are showering in two different bathrooms at the same time, you may experience a decrease

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.
