What is
The ECO4 Scheme?

The Energy Company Obligation 4 (ECO4) scheme is the latest governmental initiative aimed at enhancing energy efficiency in homes across the UK. Launched in April 2022, this program represents the fourth iteration of a series of governmental initiatives that were initiated in 2013. The preceding ECO3 scheme concluded in March 2022. ECO4 is poised to remain in effect until March 2026.

ECO4 adopts a comprehensive approach to energy efficiency, primarily emphasizing the upgrade of heating systems in UK homes. While the ECO scheme does not directly provide warmth, its core objective is to curtail carbon emissions, thereby facilitating the UK’s pursuit of carbon neutrality by 2050. Since the inception of the ECO scheme in 2012, over 2.3 million homes have reaped the benefits of improved energy efficiency standards.

The primary legislation underpinning the ECO4 scheme holds major energy companies accountable for supporting low-income households, including:

  • Provision of hardship grants to single parents.
  • Assistance to individuals with disabilities.
  • Aid for financially struggling families.

Entities such as UK Energy Support collaborate closely with Ofgem, the UK’s energy regulator, and other energy suppliers to ensure that the standards of the ECO scheme are rigorously adhered to. Local authorities play a pivotal role in identifying eligible households that stand to benefit from this scheme.

What does the ECO4 scheme cover?

The ECO4 scheme extends financial support that encompasses a broad spectrum of energy efficiency enhancements for UK homes. These include:

  • Provision of free boilers.
  • Upgrades to central heating systems.
  • Boiler replacements.
  • Installation of solar panels.
  • Deployment of air source heat pumps.
  • Incorporation of storage heaters.
  • A wide array of insulation grants, encompassing loft, underfloor, external and internal wall, cavity wall, and roof insulation.

What boilers can you get under the Free Boiler grant?

Under the aegis of the Free Boiler grant, eligible households can avail themselves of various types of boilers, including:

    • Conventional boilers.
    • Combi boilers.
    • System boilers.
    • Air-source heat pumps.

Which Types Of Boilers
Are Not Eco-Friendly?

Gas boilers

  • Environmental Impact: Gas boilers, while widely used due to their minimal electricity requirements for ignition, are among the less environmentally friendly options. The key reason behind this lies in their reliance on natural gas, a fossil fuel that, when combusted, emits carbon dioxide (CO2) and various other greenhouse gases into the atmosphere.

  • Efficiency: Older gas boilers typically hold a G-grade Energy Performance Certificate (EPC) rating, indicating a modest 70% energy efficiency. Although contemporary gas boilers are progressively improving in terms of efficiency, they still fall short of the remarkable efficiency levels offered by combi boilers or heat pumps.

  • Regulatory Changes: In response to environmental concerns, gas boilers are subject to a slew of regulations designed to ensure higher efficiency ratings, aiming for 86% or higher. These stringent regulations may lead to the gradual phasing out of traditional gas boilers in the foreseeable future.

Back boilers

  • Environmental impact: Back boilers, typically older models, exhibit significant inefficiency, with an efficiency rate of around 78%, contrasting sharply with modern counterparts like combi boilers, which exceed 90% efficiency. Although these boilers enjoyed immense popularity in the 1960s and 1970s, they emit higher levels of emissions, primarily because they are commonly installed behind fireplaces. Moreover, in the event of a leakage, there is a risk of carbon monoxide poisoning.
  • Outdated: Due to their inefficiency and the phased-out nature of back boilers, locating replacement parts has become increasingly challenging, rendering them unsustainable for long-term use.
  • Regulatory Changes: Recent government regulations mandate an efficiency rating of at least 86% for newly installed boilers, effectively rendering back boilers obsolete.

Oil boilers

  • Environmental Impact: Oil boilers function using heating oil, which falls under the category of fossil fuels. During the heating process, a substantial quantity of carbon dioxide (CO2) and sulfur dioxide is emitted into the atmosphere, thus exacerbating air pollution and contributing to the overall burden of greenhouse gas emissions.

    Efficiency: Traditional, non-condensing oil boilers demonstrate efficiency rates in the range of 60-70%. In stark contrast, contemporary iterations have made significant advancements in efficiency, achieving rates exceeding 90%. This substantial disparity underscores the environmental disadvantage of conventional oil boilers in terms of eco-friendliness.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combi boiler, short for combination boiler, this unit stands out as a highly efficient heating system that seamlessly integrates a central heating unit and a hot water system within a single, compact appliance.

Combi Boilers Deliver Hot Water Directly: Combi boilers possess the unique capability to heat water directly from the mains supply, obviating the necessity for a separate water storage tank. This dual functionality not only enhances energy efficiency but also proves to be particularly advantageous for homes where space is at a premium.

Key Features of Combi Boilers:

  • Space-Saving Design: Combi boilers, owing to their smaller size, offer valuable space-saving benefits, making them an excellent choice for homes with limited room.
  • Energy Efficiency: Combi boilers excel in energy efficiency, contributing to reduced energy consumption and subsequently lower utility bills.
  • On-Demand Hot Water: These boilers provide hot water precisely when you need it, ensuring an uninterrupted and immediate supply of hot water.
  • Straightforward Installation and Minimal Maintenance: Combi boilers are known for their ease of installation, and they typically require less maintenance compared to other heating systems.

Heat Pumps

To provide clarity, it’s important to distinguish that a heat pump functions differently from a boiler, as it neither generates heat nor relies on fossil fuels.

Instead, heat pumps are devices designed to transfer heat from one location to another. They seamlessly integrate with various distribution systems like ductwork, radiators, or underfloor heating. For instance, they can transport heat from the outdoors to the indoors for heating purposes or perform the reverse operation for cooling.

Typically powered by electricity, heat pumps can also be harnessed with renewable systems such as solar panels or wind power. This enhances their energy efficiency for both central heating and cooling applications, making them a sustainable and environmentally friendly choice in the long term.

Noteworthy attributes of heat pumps encompass:

  1. Zoning Capability: Certain heat pump systems offer zoning functionality, enabling precise temperature control in distinct areas of a residence.
  2. Integration with Existing Systems: Heat pumps can be seamlessly integrated into pre-existing central heating systems, enhancing overall efficiency and performance.

Two primary categories of heat pump systems for central heating include:

  • Air-Source Pumps: These represent the most prevalent heat pump variety, facilitating the transfer of heat between indoor and outdoor air. They are generally easier and more cost-effective to install.
  • Ground-Source: 
  • These innovative systems leverage the stable temperature of the ground as a heat source. While they boast higher efficiency, their installation is relatively more intricate and comes with a higher cost.

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


Yes, the Free Boiler Grant falls within the purview of the ECO scheme. The ECO scheme extends funding to eligible households meeting specified criteria, enabling them to qualify for free boilers, boiler replacements, central heating systems, free solar panels, heat pumps, and more.

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.

While combi boilers offer numerous advantages, they do come with certain drawbacks that merit consideration before installation. The most notable limitation is their ability to handle high water demand in a household simultaneously. If multiple individuals are showering in separate bathrooms simultaneously, there may be a noticeable reduction in water pressure. This is attributed to the absence of a backup tank, a feature present in conventional boilers, which allows them to meet high water demand efficiently.
