Our services target low-income households, providing them with fully funded boiler installations through the Government’s ECO 4 Grant. Eligibility details for this invaluable service are outlined below.
For over a decade, the UK and Scottish governments have extended free boiler grants and financial support for home energy improvements. The ECO4 boiler scheme’s Free Boiler grant is designed to provide energy-saving upgrades to eligible UK households. Criteria for free boiler or boiler replacement eligibility include:
The Energy Company Obligation 4 (ECO4) initiative represents the UK government’s latest effort to boost home energy efficiency nationwide.
Initiated in April 2022, ECO4 is the continuation of a series of governmental energy initiatives dating back to 2013, succeeding the ECO3 scheme which concluded in March 2022.
Scheduled to operate until March 2026, ECO4 adopts an all-encompassing strategy towards enhancing energy efficiency, with a particular focus on modernizing the heating systems in UK residences. Although its primary objective isn’t directly heating provision, the scheme plays a crucial role in reducing carbon emissions, contributing significantly to the UK’s ambition of achieving carbon neutrality by 2050.
Since the ECO scheme’s inception in 2012, it has positively impacted over 2.3 million homes, markedly improving their energy efficiency.
A key aspect of the ECO4 scheme is its legislative framework, which obligates major energy corporations to support households in financial hardship, including:
· Providing hardship grants to single parents,
· Assisting individuals with disabilities,
· Aiding families facing financial difficulties.
Organizations such as UK Energy Support collaborate closely with Ofgem, the UK’s energy regulatory body, along with various energy suppliers, to uphold the ECO scheme’s standards. Local governments also play a crucial role in identifying and referring households that stand to benefit from the scheme.
The ECO4 scheme offers financial support for a range of energy efficiency improvements, such as:
Environmental Impact: Gas boilers, while popular due to their low electricity usage, are among the less environmentally sustainable options. Their reliance on natural gas, a type of fossil fuel, leads to the emission of carbon dioxide (CO2) and other greenhouse gases, contributing negatively to the atmosphere.
Efficiency: The efficiency of gas boilers varies widely with age. Older models typically have a G-grade EPC rating, indicating only about 70% efficiency. Newer gas boilers have improved in this aspect but still do not match the high efficiency of combi boilers or heat pumps.
Regulatory Trends: In response to environmental concerns, gas boilers are subject to increasingly stringent regulations, such as the requirement for an efficiency rating of 86% or higher. These evolving standards suggest that gas boilers may gradually become less prevalent in the market.
Environmental Impact: Back boilers, predominantly older models, are notably less efficient (around 78%) compared to contemporary boilers like combi boilers, which achieve over 90% efficiency. Popular in the 1960s and 1970s, these boilers are not only less efficient but also higher in emissions, particularly when installed behind fireplaces. A significant risk associated with back boilers is the potential for carbon monoxide leakage.
Obsolescence Issue: The scarcity of replacement parts for back boilers, a result of their declining efficiency and gradual phase-out, renders them impractical for long-term usage. This obsolescence is compounded by their lower energy efficiency.
Regulatory Shifts: Modern regulatory standards necessitate a minimum efficiency of 86% for new boiler installations. These regulations effectively render back boilers obsolete, as they fall short of these efficiency requirements, leading to their discontinuation in the market.
Environmental Impact: Oil boilers, which utilize heating oil, a type of fossil fuel, contribute significantly to environmental concerns. Their operation results in the release of considerable amounts of carbon dioxide (CO2) and sulfur dioxide, leading to increased air pollution and greenhouse gas emissions.
Efficiency: The efficiency of oil boilers varies considerably with their age. Older models, typically non-condensing types, have efficiency rates ranging between 60-70%. While modern oil boilers have improved, achieving efficiency rates above 90%, they still fall short in eco-friendliness compared to other heating technologies.
A combination boiler, commonly known as a combi boiler, integrates a high-efficiency heating unit and a central heating system into a single compact unit.
These boilers directly heat water from the main supply, removing the necessity for a separate water storage tank. Their high energy efficiency, coupled with a compact design, makes them particularly suitable for smaller homes.
Key attributes of combi boilers are:
Heat pumps are distinct from traditional boilers as they don’t generate heat using fossil fuels. Instead, their role is to move heat from one place to another, making them versatile for both heating and cooling purposes. These systems are compatible with different distribution methods, such as ductwork, radiators, and underfloor heating, and are adept at transferring heat from outside to inside a building for heating, or the reverse for cooling.
Typically powered by electricity, heat pumps can also utilize renewable energy sources like solar or wind power. This feature makes them a highly energy-efficient
and environmentally friendly choice for both central heating and cooling.
Key Features of Heat Pumps:
Types of Heat Pump Systems for Central Heating:
The Free Boiler Grant is an integral component of the ECO4 scheme, which offers funding to eligible households for free boilers or boiler replacements, among other energy-saving measures.
While combi boilers are highly efficient and space-saving, they can struggle with high water demand. For example, simultaneous use of showers in different bathrooms might lead to reduced water pressure due to the absence of a backup water tank.
Benefits are a key qualifying criterion for the Free Boiler grant. However, eligibility is not strictly limited to benefit recipients. Envirohomes Renewables can assist in determining if you qualify for the free boiler under the ECO4 scheme, regardless of your benefit status.
