We provide a comprehensive boiler installation service funded through the Government’s ECO 4 Grant. The following outlines the eligibility criteria for this vital program.

Part of the government-funded ECO4 program, the Free Boiler Scheme in Edinburgh aims to alleviate fuel poverty, particularly among pensioners and low-income households. The scheme focuses on upgrading heating systems and installing new, efficient boilers for eligible homes. Here, we delve into the specifics of the program.

Who Qualifies For The Free Boiler Scheme?

For over a decade, the UK and Scottish governments have been offering free boiler grants and financial support to promote home energy efficiency. Under the ECO4 boiler scheme, eligible UK households can access various energy-saving upgrades. Criteria for a free boiler or boiler replacement include:

  • Household income below £19,720 per annum.
  • Homeownership.
  • Receipt of specific benefits such as Child Benefits or Income Support.
  • Pensioners over 60 with Pension Credit Benefits.
  • Gas boilers older than 15 years.
  • Boilers with an EPC rating of D or lower.
  • Malfunctioning or defective boilers.

What is
The ECO4 Scheme?

The Energy Company Obligation 4 (ECO4) initiative, inaugurated in April 2022, represents the latest in the UK government’s efforts to boost home energy efficiency nationwide. This installment follows the conclusion of ECO3 in March 2022 and is the fourth phase of strategies that commenced in 2013, set to continue until March 2026.

ECO4 adopts a holistic approach to enhancing energy efficiency, with a particular focus on upgrading heating systems within UK residences. Its primary goal is not just heating provision, but significantly reducing carbon emissions, thereby contributing to the UK’s objective of achieving carbon neutrality by the year 2050.

Since its inception in 2012, the ECO initiative has positively impacted over 2.3 million homes, elevating their energy efficiency standards. A key aspect of ECO4 is its legislative framework, which obliges major energy corporations to support households facing financial challenges, including single-parent families, individuals with disabilities, and families in financial distress.

Collaborating closely with Ofgem, the UK’s energy regulation authority, and various energy suppliers, organizations like UK Energy Support play a crucial role in upholding the ECO scheme’s standards. Local government bodies also play an instrumental role by identifying and referring households that stand to benefit most from the scheme.

What does the ECO4 scheme cover?

The ECO4 program financially supports various home energy efficiency improvements in the UK, including:

  • Free boiler installation
  • Central heating system upgrades
  • Boiler replacement
  • Solar panel installation
  • Air source heat pump installation
  • Storage heater provision
  • Insulation grants for lofts, floors, walls, and roofs.

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, commonly used for their low electricity consumption, are among the less environmentally friendly heating options. Their dependence on natural gas, a type of fossil fuel, results in the emission of carbon dioxide (CO2) and other greenhouse gases, contributing to environmental pollution.

Efficiency: The energy efficiency of older gas boilers is relatively low, typically rated G-grade EPC with only about 70% efficiency. Although newer models have improved in efficiency, they still fall short of the higher efficiency rates achieved by combi boilers and heat pumps.

Regulatory Changes: Gas boilers face stringent regulatory standards due to their environmental impact. These regulations often require a minimum efficiency rating of 86% or higher. As a result, gas boilers might gradually be phased out in favor of more eco-friendly heating solutions.


Back boilers

  • Environmental impact: Back boilers, typically older models from decades past, have a much lower efficiency rate of about 78% compared to modern boilers like combi versions, which boast over 90% efficiency. Popular in the 60s and 70s, back boilers not only emit more pollutants due to their design (often installed behind fireplaces) but also pose a risk of carbon monoxide leakage if they malfunction.

    Obsolescence of Back Boilers: The scarcity of replacement parts for back boilers, primarily due to their inefficiency and ongoing phase-out, renders them unsustainable for long-term usage. Their outdated technology struggles to meet current energy efficiency demands.

    Regulatory Shifts: Current government standards for boiler installations demand a minimum efficiency of 86%. This requirement renders back boilers, which fall significantly short of this threshold, effectively obsolete in modern heating system installations.

Oil boilers

Environmental impact: Oil boilers use heating oil, a type of fossil fuel, for their operation. This process emits considerable amounts of carbon dioxide (CO2) and sulfur dioxide, which contribute to air pollution and the increase of greenhouse gases in the atmosphere.

Efficiency: In terms of efficiency, older oil boiler models, specifically the non-condensing types, typically have efficiency rates ranging from 60-70%. While newer oil boiler models have improved, reaching efficiencies over 90%, they still fall behind in eco-friendliness compared to more modern heating solutions


Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combination boiler, commonly known as a combi boiler, combines the functionality of a high-efficiency heater and a central heating system into a single unit.

These boilers directly heat water from the main supply, doing away with the necessity for a separate hot water tank. Their energy efficiency is remarkable, and their reduced size is advantageous for homes with limited space.

Key characteristics of combi boilers are:

  • Compact design, saving valuable space
  • High energy efficiency
  • Instant hot water provision
  • Ease of installation and reduced maintenance needs

Heat Pumps

It’s important to understand that heat pumps are distinct from boilers. Unlike boilers, heat pumps don’t produce heat themselves nor do they rely on fossil fuels.

What heat pumps do is move heat from one location to another. They are versatile, compatible with various heating systems like ductwork, radiators, or underfloor heating, and can transfer heat into a building for warmth or out for cooling.

Operational mainly on electricity, heat pumps can also harness renewable energy sources like solar or wind power, enhancing their energy efficiency and eco-friendliness for both heating and cooling.

Key advantages of heat pumps are:

  • Zoning capability, allowing for independent temperature control in different areas.
  • Compatibility with existing heating systems to boost efficiency.

There are two primary types of heat pumps used for central heating:

  1. Air-source Pumps: These are common and work by exchanging heat between indoor and outdoor air. They are relatively easy and cost-effective to install.

  2. Ground-source Pumps: Utilizing the earth’s consistent underground temperature for heating, these pumps are more efficient but involve a higher installation cost and complexity.

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


This particular grant is part of the broader Energy Company Obligation (ECO) program.

The ECO program is designed to offer financial support to households that fulfill certain eligibility criteria. Successful applicants under this scheme can benefit from a range of energy-efficient solutions including, but not limited to, complimentary boiler installations or replacements, central heating systems, solar panels, and heat pump installations.

Despite the many benefits of combi boilers, there are certain limitations to consider before installing one. A key issue they face is managing high water usage at the same time in a household. For example, using multiple showers simultaneously in different bathrooms could lead to reduced water pressure.

This problem occurs because combi boilers, unlike standard boilers, do not have an auxiliary tank to handle sudden increases in water usage.

Eligibility for the Free Boiler grant primarily hinges on receiving certain benefits, but this is not an absolute requirement. You might still qualify for the grant even without benefits. Envirohomes Renewables offers guidance and assistance in determining your eligibility for a free boiler through the ECO4 scheme, regardless of your benefits status.
