Our specialized services are particularly focused on aiding economically challenged households, primarily those on benefits, by offering 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.

In Scotland, the ‘Free Boiler Scheme’ or ‘Free Boiler Replacement Scheme’, part of the Scottish segment of the government-funded ECO4 programme, is a thoughtful initiative aimed at eradicating fuel poverty. This scheme is particularly beneficial for pensioners and lower-income households, focusing on the upgrade of heating systems and the installation of new boilers to ensure efficient energy use and reduced heating costs.

Who Qualifies For The Free Boiler Scheme?

The UK and Scottish governments have been consistently offering free boiler grants and home energy assistance for over a decade. Under the ECO4 scheme, the Free Boiler grant is intended to make various energy-saving improvements accessible to UK households. The primary aim is to alleviate the burden of high heating bills and energy costs on eligible homeowners. Qualification for this grant is based on a set of criteria, including but not limited to:

  • Household income below £19,720 per year.
  • Homeownership status.
  • Receipt of specific benefits such as Child Benefits and Income Support.
  • Being a pensioner (over 60) receiving Pension Credit Benefits or similar assistance.
  • Owning a gas boiler that is over 15 years old.
  • A boiler with an Energy Performance Certificate (EPC) rating of D or lower.

What is
The ECO4 Scheme?

Initiated in April 2022, the Energy Company Obligation 4 (ECO4) scheme is the latest in a succession of UK government efforts to boost the energy efficiency of homes nationwide. Scheduled to run until March 2026, the ECO4 scheme takes a comprehensive approach, primarily focusing on upgrading and modernizing heating systems in residential properties across the UK. Beyond just enhancing home heating, the scheme plays a crucial role in reducing carbon emissions, aligning with the UK’s ambitious target of achieving carbon neutrality by 2050.

Since its launch, the ECO program has been instrumental in enhancing the energy efficiency of over 2.3 million homes, marking a notable achievement in the UK’s journey towards environmental sustainability.

Under ECO4, large energy companies are mandated to provide support to low-income households. This includes offering hardship grants for single-parent families, support for individuals with disabilities, and assistance to families in financial distress. Entities like UK Energy Support work in conjunction with Ofgem, the UK’s energy regulatory authority, and other energy suppliers to ensure compliance with the ECO program’s standards. Local authorities also play a key role in identifying and directing households that stand to gain the most from this scheme.

What does the ECO4 scheme cover?

The ECO4 scheme offers financial support that covers a wide range of energy efficiency improvements for UK homes, such as:

  • Free boilers
  • Central heating systems
  • Boiler replacement
  • Solar panels
  • Air source heat pump
  • Storage heaters
  • Various types of insulation grants (e.g. loft, underfloor, external and internal wall, cavity wall, 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 of Gas Boilers: Gas boilers, popular for their low electricity requirements for ignition, unfortunately rank lower in environmental friendliness. Their reliance on burning natural gas, a type of fossil fuel, results in the emission of carbon dioxide (CO2) and other greenhouse gases, contributing to atmospheric pollution.

    Energy Efficiency of Gas Boilers: Traditional gas boilers typically have a G-grade EPC rating, indicating an energy efficiency of only about 70%. Although recent advancements have led to more efficient modern gas boilers, they still do not match the higher efficiency levels achieved by combi boilers or heat pumps.

    Regulatory Shift: Environmental concerns have led to stricter regulations for gas boilers, mandating efficiency ratings of 86% or higher. These evolving standards suggest a potential shift towards reducing the usage of gas boilers in the future


Back boilers

  • Environmental Considerations of Back Boilers: Back boilers, typically older models popular in the 60s and 70s, suffer from low efficiency, averaging around 78%, which is significantly lower than the efficiency of modern boilers like combi boilers, which exceed 90%. Despite their past popularity, especially as units often 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 decline in the use of back boilers, largely due to their inefficiency, has led to a shortage of replacement parts. This scarcity, coupled with their gradual phase-out, makes them an unsustainable choice for long-term usage.

  • Regulatory Standards: 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.

Oil boilers

  • Environmental Footprint of Oil Boilers: Oil boilers, which use heating oil as a fuel source, have a notable impact on the environment. 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 escalation of greenhouse gas emissions. 

  • Efficiency : Traditional oil boilers, particularly the older and non-condensing types, show relatively modest efficiency, with their rates hovering around 60-70%. Although newer models have seen improvements in efficiency, achieving rates above 90%, oil boilers still fall short in eco-friendly performance when compared to more modern heating solutions.

Which Types Of Boilers
Are Eco-Friendly?

Combi boilers

A combination boiler, commonly known as a combi boiler, serves as both a high-efficiency heating unit and a central heating system.

These boilers directly heat water from the main supply, removing the necessity for a separate water storage tank. They are recognized for their high energy efficiency. Their compact design is particularly advantageous in smaller homes, where space is at a premium.

Key characteristics of combi boilers are:

  • Compact design, saving space
  • High energy efficiency
  • Instant hot water supply
  • Easier installation and reduced maintenance needs

Heat Pumps

It’s important to understand that heat pumps are distinct from boilers. They don’t create heat themselves nor do they use fossil fuels.

Heat pumps function by relocating heat from one location to another and are versatile enough to work with various heating distribution systems, including ductwork, radiators, and underfloor heating. For instance, they can move heat from outside into a building for heating purposes, or from inside to outside for cooling.

Typically powered by electricity, heat pumps can also be connected to renewable energy sources like solar panels or wind turbines. This feature makes them a highly efficient solution for both heating and cooling, as well as more eco-friendly over the long term.

Key features of heat pumps include:

  • Zoning capabilities, allowing for independent temperature control in different rooms or areas of a home.
  • Compatibility with existing central heating systems to boost efficiency.

Regarding types of heat pump systems for central heating:

  • Air-source pumps: These are quite common. They work by exchanging heat between the indoor environment and the outside air and are generally more straightforward and cost-effective to install.
  • Ground-source pumps: These utilize the earth’s stable underground temperature for heat exchange. While they offer higher efficiency, they tend to be costlier and more complex to set up compared to air-source pumps.

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


The Free Boiler Grant is a component of the broader ECO scheme, which offers funding to households meeting specific criteria. This allows them to qualify for various energy-efficient home improvements, including free boilers or boiler replacements, and more.

While combi boilers offer numerous advantages, they can face challenges in high-demand situations. For instance, if multiple showers are used simultaneously, the absence of a backup tank may lead to decreased water pressure.
