One of the most significant initiatives we participate in is the ‘Free Boiler Scheme’ or ‘Free Boiler Replacement Scheme’ in Inverness, which falls under the government-funded ECO4 program. This program is designed to tackle fuel poverty, especially among pensioners and lower-income households, by upgrading heating systems and providing new boilers where needed. Let’s delve deeper into the details of this scheme and who qualifies for it.

Who Qualifies For The Free Boiler Scheme?

For over a decade, both the UK and Scottish governments have been offering free boiler grants and financial support to improve home energy efficiency across the country. The Free Boiler grant, a part of the ECO4 boiler scheme, aims to provide various energy-saving improvements to households in Inverness. The scheme’s objective is to reduce heating bills and energy costs by offering eligible homeowners free boilers or free boiler replacements, subject to certain criteria. These criteria include:

Eligibility criteria include:

  • Total household income less than £19,720 per annum.
  • Applicant must own a home in Iverness
  • Individuals receiving benefits such as Child benefits or income support are eligible
  • Pensioners (over 60) receiving Pension Credit Benefits.
  • Current gas boiler aged over 15 years.
  • Boiler with an Energy Performance Certificate (EPC) rating of D or lower.
  • Broken or faulty boiler.

What is
The ECO4 Scheme?

The Energy Company Obligation 4 (ECO4) scheme is the latest government policy aimed at enhancing energy efficiency in homes across the UK. Launched in April 2022, this scheme represents the fourth installment in a series of government initiatives that began in 2013. It serves as the successor to the ECO3 scheme, which concluded in March 2022. The ECO4 scheme is set to run until March 2026.

ECO4 takes a comprehensive approach to improving energy efficiency, with a primary focus on upgrading heating systems in UK homes. While the scheme doesn’t directly provide warmth, its goal is to reduce carbon emissions, aligning with the UK’s objective to achieve 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 primary legislation of the ECO scheme holds large energy companies accountable for supporting low-income households. This support includes offering hardship grants to single parents, people 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 the ECO scheme’s standards. Local authorities play a pivotal role in identifying eligible households that would benefit from this program.

What does the ECO4 scheme cover?

The ECO4 scheme in Inverness provides financial support for a wide range of energy efficiency improvements in 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?

Residents in Inverness have several boiler options to choose from:

    • 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 among the most common types of boilers due to their minimal electricity requirements for ignition. However, they are considered one of the least eco-friendly options. 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 often have a G-grade Energy Performance Certificate (EPC) rating, indicating only 70% energy efficiency. While modern gas boilers are becoming more efficient, they still can’t match 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 of having 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 typically older models and are highly inefficient, with an efficiency rate of only 78% when compared to modern versions like combi boilers (which achieve over 90% efficiency). These older boilers were popular in the 60s and 70s but produce higher levels of emissions, especially when installed behind fireplaces. Additionally, if they leak, it could result in carbon monoxide poisoning.
  • Outdated: Due to their inefficiency and the industry’s shift towards more sustainable options, parts for back boilers are becoming scarce, making them less suitable for long-term use.
  • Regulatory Changes: Government regulations now mandate an 86% efficiency rating for new boiler installations, effectively making back boilers obsolete.

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 typically have efficiency rates of 60-70%. In comparison, modern versions have made significant strides in efficiency, achieving rates of over 90%. However, oil boilers still lag behind in terms of eco-friendliness.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

Among the eco-friendly heating solutions available in Inverness, combi boilers stand out. A combi boiler, short for combination boiler, is a highly efficient heating unit that also serves as a central heating system. Here are some notable features of combi boilers:

  • Space Saving: Combi boilers are known for their compact size, making them particularly suitable for smaller homes.
  • Energy Efficiency: Combi boilers operate by heating water directly from the mains, eliminating the need for a separate water storage tank. This results in high energy efficiency.
  • On-Demand Hot Water: Combi boilers provide hot water on demand, reducing the need for separate water tanks and minimizing heat loss.
  • Simple Installation and Lower Maintenance: Due to their design, combi boilers are generally easier and quicker to install compared to other boiler types. They also require less maintenance and upkeep since there are fewer components to worry about.

Heat Pumps

While boilers are a popular choice for heating in Inverness, heat pumps offer an alternative approach. It’s important to note that heat pumps are not boilers; they do not generate heat or rely on fossil fuels. Instead, heat pumps are devices designed to transfer heat from one place to another. They work seamlessly with various distribution systems, such as ductwork, radiators, or underfloor heating. For instance, heat pumps can transfer heat from the outside environment to the inside of a building for heating or vice versa for cooling.

Heat pumps typically run on electricity, but they can also be powered by renewable energy systems like solar panels or wind power. This makes them highly energy-efficient for both central heating and cooling purposes, all while being more environmentally friendly in the long run.

Some additional advantages of heat pumps in Inverness include:

  • Zoning Capability: Certain heat pump systems allow for zoning, meaning you can control the temperature in different areas of your home independently, increasing comfort and energy efficiency.
  • Integration with Existing Systems: Heat pumps can be integrated into existing central heating systems, enhancing overall efficiency.

There are two main types of heat pump systems for central heating:

Air-Source Heat Pumps (ASHP): These are the most common types of heat pumps in Inverness. ASHPs transfer heat between the indoor and outdoor air. They are generally easier to install and less expensive compared to ground-source heat pumps.

Ground-Source Heat Pumps (GSHP): GSHPs use the stable temperature of the ground as a heat source. They are more efficient than ASHPs but tend to be more expensive and require a more complex installation process.

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


Yes, the Free Boiler Grant falls under the ECO scheme. The ECO scheme provides funding to eligible households in Inverness and across the UK, based on specific criteria. This enables them to qualify for a free boiler or boiler replacement, central heating systems, free solar panels, heat pumps, and more.

While combi boilers offer numerous benefits, they do come with a few considerations that should be taken into account:

The most prominent issue is that these boilers may struggle to meet high water demands in a household at one time. For instance, if two people are showering in two different bathrooms simultaneously, you may notice a decrease in water pressure. This is because combi boilers do not have a backup tank, as conventional boilers do, to handle high water demand scenarios.

Benefits play a significant role in determining eligibility for the Free Boiler Grant; however, you may still be eligible even if you do not receive any benefits. Envirohomes Renewables can help you assess your eligibility for a free boiler under the ECO4 scheme, regardless of whether you receive benefits or not.
