ECO 4 Boiler Scheme

ECO 4 Boiler Scheme

Are you concerned about rising energy bills and the environmental impact of your home heating system? Then look no further than the ECO 4 Boiler Scheme, a government initiative empowering UK households to upgrade to sustainable and energy-efficient heating solutions. 

A 2022 study by the Energy Saving Trust found that around 14 million homes in the UK are eligible for the ECO 4 Scheme, representing 40% of all households.

This detailed blog post delves deep into the ECO 4 Boiler Scheme, providing everything you need to know about reducing your carbon footprint, alleviating fuel poverty, saving money on energy bills, and enjoying a warmer, more comfortable home.

What is the ECO 4 Boiler Scheme?

The ECO 4 Scheme is a government-backed program aimed at tackling fuel poverty and reducing carbon emissions in UK homes. This initiative helps eligible households, particularly those with low incomes, install energy-efficient heating systems through financial grants. By participating in the ECO4 Scheme, you can upgrade from an outdated, inefficient non-condensing boiler to a modern, eco-friendly condensing model, reaping a multitude of benefits for your wallet and the planet.

What Heating Systems Are Covered by the ECO 4 Scheme?

The ECO 4 Scheme offers flexibility in choosing your ideal green heating solution, catering to diverse preferences and property types. Here’s a breakdown of the heating systems covered:

  1. High-efficiency Gas Boilers:
  • Boasting an A or B efficiency rating, these modern boilers significantly reduce gas consumption and lower bills.
  • Ideal for those who prefer the familiarity of gas heating and have suitable flue venting for installation.
  1. Air Source Heat Pumps (ASHPs):
  • Eco-friendly champions, ASHPs extract heat from the air outside, even in chilly temperatures.
  • Perfect for well-insulated homes and offering renewable warmth, they require minimal maintenance and have lower running costs.
  1. First Time Central Heating System:
  • The ECO 4 Boiler scheme often extends its coverage to central heating systems, including the associated components such as radiators, pipes, and controls. Upgrading or optimizing these components for improved efficiency may be eligible for support.
  1. Biomass Boilers:
  • For a carbon-neutral choice, biomass boilers burn wood pellets or similar fuels, providing warmth with environmentally friendly credentials.
  • Ideal for those with access to fuel storage and willing to handle potential maintenance needs.

Additional Options:

While not always officially listed, the scheme can sometimes cover:

  • Electric Storage Heater Upgrades: Replacing inefficient models with high heat retention storage heaters can improve efficiency and comfort.
  • Solar Photovoltaics (PV): In electrically heated homes, solar PV may be installed alongside certain other upgrades to maximize renewable energy usage.

Am I Eligible for the ECO 4 Boiler Scheme?

Am I Eligible for the ECO 4 Boiler Scheme?

The Government has allocated £4 billion of funding to the ECO4 scheme and several changes were made to the eligibility criteria.

In order to qualify for the ECO4 Grant, you must meet the below criteria;

  • Homeowners or private tenants
  • Households with low incomes who receive certain benefits, including:
    • Income-based Jobseeker’s Allowance (JSA)
    • Income-related Employment and Support Allowance (ESA)
    • Income Support (IS)
    • Pension Credit Guarantee Credit (PCGC)
    • Working Tax Credit (WTC)
    • Child Tax Credit (CTC)
    • Universal Credit (UC)
    • Housing Benefit
    • Pension Credit Savings Credit (PCSC)
    • Child Benefit*

Property eligibility:

  • Properties with an EPC rating of lower D, E, F, or G.
  • Properties with inefficient heating systems may also be eligible.

A survey by Citizens Advice in 2023 found that lack of awareness was the biggest barrier for eligible households, followed by confusion about the application process and concerns about upfront costs.

EPC Rating: Your Home’s Energy Performance Snapshot

    • What it is: An EPC (Energy Performance Certificate) is a document that rates your home’s energy efficiency on a scale of A (most efficient) to G (least efficient). It considers factors like insulation, heating systems, and energy usage.
    • How it’s obtained: An accredited energy assessor surveys your home to generate the EPC.
  • Why it matters:
    • Indicates potential energy savings and carbon emissions reductions.
    • Required for selling or renting a property in the UK.
    • Crucial for determining eligibility for energy-saving schemes like ECO4.

Installing greener heating systems Via ECO 4 Boiler Scheme

The focus of ECO4 is on the replacement of outdated boilers with more environmentally friendly alternatives. In alignment with the national objective of achieving net zero emissions by 2050, the ECO3 initiative already excluded coal-fuelled heating systems. ECO4 will uphold this policy while expanding the exclusion list to include oil- and LPG-fuelled heating systems.

Under the new scheme, the government encourages individuals to transition to greener alternatives for their heating needs, particularly emphasizing the adoption of heat pumps and biomass boilers. Additionally, ECO4 continues the installation of solar photovoltaics (PV) in all electrically heated homes.

1. What types of boilers can I get through the ECO 4 Boiler scheme?

Answer: The ECO 4 Scheme prioritizes the installation of A-rated condensing boilers, which are the most energy-efficient models on the market. However, if your existing boiler can be economically repaired, you may receive a grant for repairs instead. Additionally, if your current boiler is relatively efficient but not the latest model, a grant may be available to contribute towards upgrading to a more energy-saving option.

2. How much funding can I receive through the ECO 4 Scheme?

Answer: The amount of funding you receive depends on several factors, including your household income, energy bills, and letter of benefits. Additionally, it also depends on the specific ECO 4 measure you’re applying for. For boiler upgrades, you could receive up to 100% of the installation cost if you meet the eligibility criteria.

3. Do I need to pay anything to apply for ECO 4 funding?

Answer: No, applying for ECO 4 funding is free. Registered installers will handle the application process on your behalf and will only charge you for the installation if your application is approved.

4. What happens if my current boiler needs repairs instead of replacement?

Answer: The ECO 4 Boiler Scheme also offers funding for boiler repairs in certain cases. If your boiler is relatively new and can be economically repaired to improve its efficiency, you may be eligible for a repair grant.

5. How long does it take to get my new boiler installed after applying for ECO 4 funding?

Answer: The timeframe can vary depending on the workload of your chosen installer and the availability of boilers. However, once your application is approved, you can expect the installation as soon as possible.
