Focused on assisting low-income families, particularly those on benefits, we offer a fully funded boiler installation service. This initiative is part of the Government’s ECO 4 Grant. The grant aims to make energy efficiency more accessible to those in need, and we detail the eligibility requirements below.
The Free Boiler Scheme, also known as the Free Boiler Replacement Scheme in Scotland, is a part of the ECO4 programme funded by the government. Its objective is to reduce fuel poverty, particularly among pensioners and low-income households, by upgrading existing heating systems and installing new, efficient boilers.
For over a decade, the UK and Scottish governments have been providing free boiler grants and financial support to improve home energy efficiency. Under the ECO4 scheme, the Free Boiler grant aims to deliver energy-saving improvements to households across the UK. The eligibility criteria for this grant include:
The Energy Company Obligation 4 (ECO4) program represents the latest initiative by the UK government to boost home energy efficiency nationwide.
Initiated in April 2022, ECO4 is the continuation of a series of government efforts to enhance energy efficiency, with the first of these initiatives starting in 2013 and the preceding ECO3 scheme concluding in March 2022.
Set to continue until March 2026, the ECO4 program adopts an all-encompassing strategy focused on improving energy efficiency, with a particular emphasis on upgrading home heating systems. While not directly aimed at providing heating, the ECO4 scheme plays a crucial role in reducing carbon emissions, aligning with the UK’s objective to achieve carbon neutrality by 2050.
Since the inception of the ECO program in 2012, it has brought enhanced energy efficiency to over 2.3 million homes.
A key aspect of the ECO4 scheme is the accountability it places on large energy companies to assist low-income families. This includes providing hardship grants to single parents, support for individuals with disabilities, and aid to families in financial distress.
Organizations such as UK Energy Support collaborate closely with Ofgem, the UK’s energy regulatory body, and other energy providers to uphold the ECO program’s standards. Local governments also play a crucial role in identifying and recommending households that stand to benefit most from the scheme.
The ECO4 scheme offers financial support that covers a wide range of energy efficiency improvements for UK homes, such as:
Environmental Impact: Gas boilers, widely used due to their low electrical ignition requirement, unfortunately rank among the less eco-friendly heating options. Their dependence on natural gas, classified as a fossil fuel, results in significant emissions of carbon dioxide (CO2) and other greenhouse gases, contributing to environmental concerns.
Efficiency Aspects: The energy efficiency of older gas boilers, often classified with a G-grade EPC rating, is relatively low at about 70%. Although newer models of gas boilers have shown improvements in efficiency, they still fall short when compared to the efficiency levels achievable by combi boilers or heat pumps.
Regulatory Impact Environmental considerations have led to stringent regulations for gas boilers, requiring them to have an efficiency rating of 86% or higher. These evolving standards indicate a potential shift towards phasing out gas boilers in the foreseeable future.
Environmental Impact: Back boilers, typically older models prevalent in the 60s and 70s, lag in efficiency with only about 78% efficiency compared to modern boilers like combi boilers, which exceed 90%. Despite their past popularity, especially as units installed behind fireplaces, back boilers are known for higher emissions. Moreover, there’s a risk of carbon monoxide leakage if these boilers are not properly maintained.
Challenges with Back Boilers: The scarcity of replacement parts, owing to their inefficiency and gradual phase-out, has made back boilers less viable for long-term usage. This decline in usage reflects their decreasing sustainability in the current heating market.
Regulatory Compliance: Current government standards for boiler installations demand a minimum of 86% efficiency. This regulation effectively renders back boilers obsolete, as they fall short of meeting these modern efficiency requirements.
Environmental Impact: Oil boilers, which utilize heating oil as a source of energy, have a notable environmental impact. The combustion of this fossil fuel results in the release of substantial amounts of carbon dioxide (CO2) and sulfur dioxide, contributing significantly to air pollution and the escalation of greenhouse gas emissions.
Efficiency Comparison: Traditional oil boilers, particularly the older and non-condensing models, typically exhibit efficiency levels ranging from 60-70%. While recent advancements have led to more efficient modern oil boilers with efficiency rates surpassing 90%, they still fall short in terms of eco-friendliness compared to other heating options.
A combi boiler, known more formally as a combination boiler, is an all-in-one unit that efficiently combines heating and central heating systems.
These boilers directly heat water from the main supply, removing the necessity for a separate water storage tank. This makes them highly efficient in terms of energy use. Their compact design is an added advantage, especially beneficial for smaller homes.
Key attributes of combi boilers are:
It’s important to note that heat pumps differ fundamentally from boilers. Unlike boilers, heat pumps do not produce their own heat and do not operate on fossil fuels.
Rather, heat pumps are designed to move heat from one location to another and are compatible with various heating distribution systems, including ductwork, radiators, and underfloor heating. They are adept at transferring heat from the exterior to the interior of a building for heating purposes, and can also reverse this process for cooling.
Heat pumps typically run on electricity but can also utilize renewable energy sources, such as solar or wind power. This capability renders them highly efficient for both heating and cooling, as well as more environmentally sustainable over the long term.
Additional key features of heat pumps are:
Regarding types of heat pump systems for central heating:
While combi boilers offer numerous benefits, one of their limitations is handling high simultaneous water demand, which can lead to reduced pressure due to the lack of a backup tank.
Although receiving benefits is a primary criterion, you may still be eligible for the Free Boiler Grant. Envirohomes Renewables can assist in assessing your eligibility for the ECO4 scheme, regardless of your benefits status.
