The ‘Free Boiler Scheme’ in Scotland, a segment of the government-backed ECO4 program, targets the eradication of fuel poverty. This is particularly crucial for pensioners and lower-income families. The scheme’s focus is on modernizing heating systems and facilitating new boiler installations to reduce heating bills and overall energy expenditure.


Who Qualifies For The Free Boiler Scheme?

For over a decade, both the UK and Scottish governments have been dedicated to offering financial assistance for home energy improvements. The Free Boiler grant under the ECO4 scheme is available to UK households that meet specific criteria, including:

  • An annual household income below £19,720
  • Homeownership status
  • Receipt of certain benefits, like Child Benefits and Income Support
  • Pensioners over 60 receiving Pension Credit Benefits or similar
  • Ownership of a gas boiler older than 15 years
  • A boiler with an Energy Performance Certificate (EPC) rating of D or lower
  • Possessing a broken or faulty boiler

What is
The ECO4 Scheme?

The Energy Company Obligation 4 (ECO4) scheme, initiated in April 2022, is the latest government effort to enhance home energy efficiency in the UK. This scheme, set to continue until March 2026, is the fourth iteration of government initiatives that began in 2013, following the conclusion of the ECO3 scheme.

ECO4 focuses on heating system upgrades in UK homes, aiming not just at warmth but at reducing carbon emissions and assisting the UK in achieving its 2050 carbon-neutral goals. Since 2012, over 2.3 million homes have benefited from the ECO scheme, enhancing energy efficiency standards. Key aspects of the ECO4 scheme include holding large energy companies responsible for aiding low-income households, such as single parents, individuals with disabilities, and financially struggling families.

What does the ECO4 scheme cover?

The ECO4 scheme encompasses financial support for a variety of energy efficiency improvements, including:

  • Free boiler installations
  • Central heating systems
  • Boiler replacements
  • Solar panel installations
  • Air source heat pumps
  • Storage heaters
  • Various 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 one of the most common types of boilers as they require minimal electricity to fire up. However, they are one of the least eco-friendly types of boilers. This is because they rely on natural gas, a fossil fuel, which, when burned, releases carbon dioxide (CO2) and other greenhouse gases into the atmosphere.

  • Efficiency: Older gas boilers have a G-grade EPC rating with only 70% energy efficiency. While modern gas boilers are becoming more efficient, they can’t beat the efficiency levels of combi boilers or heat pumps.

  • Regulatory changes: Due to environmental factors, gas boilers have many regulations to comply with, such as having 86% or higher efficiency ratings. This may see gas boilers being phased out in the near future.

Back boilers

  • Environmental Impact: Back boilers, typically much older models, lag in efficiency with only about 78% effectiveness, a stark contrast to more modern boilers like combi boilers which boast over 90% efficiency. Once a common choice in the 60s and 70s, back boilers are now known for their higher emission levels, particularly when installed behind fireplaces. A significant risk associated with these boilers is the potential for carbon monoxide leakage, posing serious health hazards.

  • Outmoded: The dwindling availability of parts for back boilers is a direct consequence of their reduced efficiency and gradual obsolescence. This scarcity renders them an unsustainable option for long-term use, as maintaining and repairing them becomes increasingly challenging.

  • Regulatory Shifts: Current government regulations mandate a minimum efficiency rating of 86% for new boiler installations. This requirement effectively renders back boilers obsolete, as they fail to meet these efficiency standards, pushing them out of the market in favor of more energy-efficient and environmentally friendly alternatives

Oil boilers

  • Environmental impact: Oil boilers, which utilize heating oil as a fossil fuel, significantly contribute to environmental pollution. They emit a substantial amount of carbon dioxide (CO2) and sulfur dioxide (SO2), exacerbating air pollution and greenhouse gas emissions.
  • Efficiency: Older models of oil boilers generally have efficiency rates between 60-70%, considerably lower than modern heating systems. Although newer oil boilers have improved with efficiencies over 90%, they still lag behind more eco-friendly alternatives, making them less desirable in terms of environmental sustainability and long-term cost-effectiveness.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combination boiler, commonly referred to as a combi boiler, combines the functions of a heater and central heating system into one compact unit.

These boilers directly heat water from the main supply, negating the necessity for a separate water storage tank. Such a system not only saves energy but is also particularly beneficial for smaller residences due to its reduced size.

Key characteristics of combi boilers are:

  • Compact design that conserves space
  • High energy efficiency
  • Instantaneous hot water supply
  • Ease of installation and minimal maintenance demands

Heat Pumps

Heat pumps differ fundamentally from boilers, as they don’t produce heat nor operate on fossil fuels. Their primary function is to relocate heat from one location to another, making them versatile for heating and cooling purposes. This process is compatible with a variety of heating distribution systems, such as ductwork, radiators, or underfloor heating systems, enabling them to move heat indoors for warmth or extract indoor heat for cooling.

Operating predominantly on electricity, heat pumps can also harness renewable energy sources like solar or wind power, enhancing their appeal as energy-efficient and eco-friendly solutions for both heating and cooling needs.

Key advantages of heat pumps include:

  • Zoning Capability: Certain models offer the ability to control temperatures in different areas independently, enhancing comfort and efficiency.
  • Integration Flexibility: They can seamlessly integrate with existing central heating systems, boosting overall energy efficiency.

Varieties of Heat Pump Systems:

  • Air-Source Pumps: Common and popular, these pumps exchange heat between indoor and outdoor air, known for their relative ease and lower cost of installation.
  • Ground-Source Pumps: Utilizing the earth’s stable underground temperature for heating, these pumps are highly efficient but come with higher installation complexity and costs.

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


The Free Boiler grant is part of the ECO scheme, which provides funding for eligible households to receive free boilers or boiler replacements, among other benefits.

While combi boilers are efficient, they may struggle with high water demand. For instance, simultaneous showers in different bathrooms can lead to decreased water pressure.
