  • Having a boiler with a D or lower EPC rating, or if it’s broken or faulty.

What is
The ECO4 Scheme?

The Energy Company Obligation 4 (ECO4) initiative represents the latest stride by the UK government to boost energy efficiency in residential properties nationwide.

Initiated in April 2022, ECO4 is the continuation of a series of government efforts that commenced in 2013, following the conclusion of the ECO3 scheme in March 2022. This new phase is scheduled to continue until March 2026.

ECO4 adopts a holistic approach to enhancing energy efficiency, with a specific focus on the modernization of heating systems in homes across the UK. While its primary objective isn’t directly providing heating, the scheme plays a crucial role in cutting down carbon emissions, contributing to the UK’s ambition of achieving carbon neutrality by 2050.

Since the ECO program’s inception in 2012, it has positively impacted over 2.3 million homes through raised energy efficiency standards.

A key aspect of ECO4’s legislative framework is ensuring that major energy companies play a significant role in aiding households in financial need. This includes offering support to single parents, individuals with disabilities, and families experiencing financial hardship.

Organizations like UK Energy Support collaborate closely with Ofgem, the UK’s energy regulatory body, along with various energy providers, to uphold the ECO program’s standards. Local governments also play a critical role in identifying and recommending households that stand to benefit from the initiatives under this scheme

What does the ECO4 scheme cover?

The ECO4 program provides comprehensive financial assistance for numerous energy-efficient upgrades in UK residences, including:

  • No-cost boiler installations
  • Upgrades to central heating systems
  • Boiler replacements
  • Installation of solar panel systems
  • Implementation of air source heat pumps
  • Installation of storage heaters
  • A variety of insulation grants covering areas like lofts, underfloor, external and internal walls, cavity walls, 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: While gas boilers are a popular choice due to their minimal electricity requirements, they rank lower in environmental friendliness. Their operation relies on burning natural gas, a type of fossil fuel. This combustion process emits carbon dioxide (CO2) and other greenhouse gases, contributing to environmental pollution.

  • Efficiency: The energy efficiency of older gas boiler models is relatively low, typically rated G-grade on the EPC scale, equating to about 70% efficiency. Although newer models of gas boilers have seen improvements in efficiency, they still do not match the higher efficiency levels achieved by combi boilers or heat pump systems.

  • Regulatory Changes In response to environmental concerns, gas boilers are subject to increasingly stringent regulations. These include requirements for a minimum efficiency rating of 86% or higher. Such regulatory pressures suggest that gas boilers might gradually be phased out in favor of more eco-friendly heating solutions.

Back boilers

  • Environmental Impact: Back boilers, typically dating back to older models, fall significantly short in efficiency, achieving only about 78%, in contrast to the more than 90% efficiency of modern boilers like combi boilers. Popular in the 1960s and 1970s and often installed behind fireplaces, these boilers are known for higher emission levels. Furthermore, there’s a risk of carbon monoxide leakage with these older systems.

  • Outdated: The declining availability of parts for back boilers, a result of their inefficiency and gradual phase-out, hampers their long-term sustainability. This scarcity of components makes maintenance and repair increasingly difficult.

  • Regulatory Impact: Current regulations stipulate that new boiler installations must achieve at least an 86% efficiency rating. This requirement renders back boilers obsolete, as they fail to meet these efficiency standards, leading to their discontinuation in modern heating solutions.

Oil boilers

  • Environmental impact: Using heating oil as fuel, oil boilers contribute to environmental issues. The combustion of this fossil fuel results in the release of substantial amounts of carbon dioxide (CO2) and sulfur dioxide, exacerbating air pollution and the emission of greenhouse gases.
  • Efficiency: The efficiency of older oil boilers, particularly non-condensing types, ranges between 60-70%. Although recent models have shown improvements in efficiency, achieving over 90% in some cases, oil boilers still fall short in eco-friendliness when compared to more modern and greener heating solutions.


Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combination boiler, commonly referred to as a combi boiler, merges a high-efficiency heating mechanism with a central heating system.

These boilers directly warm water from the main supply, removing the necessity for an additional water storage tank. Renowned for their high energy efficiency, combi boilers are also compact, an ideal fit for smaller homes.

Key advantages of these boilers are their space-saving design, due to their smaller size, and their ability to provide hot water on demand. Additionally, combi boilers are favored for their straightforward installation process and reduced maintenance needs, making them a convenient and efficient choice for modern heating requirements.

Heat Pumps

Heat pumps stand apart from boilers as they function differently. Unlike boilers, heat pumps do not create heat themselves nor do they rely on burning fossil fuels.

What heat pumps do is shift heat from one location to another, making them adaptable to a variety of heating systems such as ducts, radiators, or underfloor heating. They’re particularly effective in moving heat from outdoors to indoors for heating purposes, or the reverse for cooling.

Operating primarily on electricity, heat pumps can also be integrated with renewable energy sources like solar or wind power, enhancing their appeal as an energy-efficient and eco-friendly option for both heating and cooling.

Unique features of heat pumps include:

  • Zoning capabilities: Certain heat pump models offer zoning control, allowing you to adjust temperatures in different areas of your home independently.
  • Integration with existing heating systems: Heat pumps can be seamlessly incorporated into current central heating setups, boosting overall energy efficiency.

There are two main types of heat pumps for central heating:

  • Air-source heat pumps: These are widely used and work by transferring heat between indoor and outdoor air. They’re known for their simpler, cost-effective installation.
  • Ground-source heat pumps: These extract heat from the ground’s stable temperature, offering superior efficiency but at a higher cost and with more complex installation requirements.

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


This subsidy is a part of the Energy Company Obligation (ECO) program.

Through the ECO program, financial assistance is extended to households that fulfill specified eligibility criteria. This aid enables these households to access various energy-efficient home improvements at no cost, such as new or replacement boilers, central heating systems, complimentary solar panels, and heat pump installations.

Combi boilers offer numerous advantages, but there are some drawbacks to be aware of before installation.

A significant limitation is their performance under high water usage situations. For instance, if multiple showers are running simultaneously in a home, a drop in water pressure might be observed. This is due to the lack of a backup water tank in combi boilers, a feature commonly found in traditional boilers, which helps to accommodate large water usage.

Receiving benefits is a key factor in qualifying for the Free Boiler grant, but eligibility may still be possible without them. Envirohomes Renewables is equipped to assist in determining if you meet the criteria for a free boiler through the ECO4 scheme, regardless of your benefits status.
