Our team of electric heating engineers specialises in ECO 4 grants which provide a fully funded service to households on benefits. Please see the qualification process below. 

The Energy Company Obligation (ECO4) scheme is a UK government initiative that is aimed at improving energy efficiency in homes by offering home improvements like free heat pumps and insulation. This is to help low-income households and rural homes, as well as boost the country’s carbon-neutral goals.

ECO4 is the latest phase in the ECO programme and was introduced in April 2022. It is set to run until March 31, 2026, and is part of the government’s long-term plan for increased sustainability in homes by 2035.

ECO4 is focused on providing energy-efficient measures to vulnerable households to create more sustainable homes with improved energy efficiency and reduced carbon emissions. Ultimately, this will help to advance the plan for long-term sustainability.

What makes ECO4 different from ECO3?

The ECO4 and ECO3 schemes share similar principles, but there are some important differences that set them apart. These differences include:

What is
Electric Storage Heating?

Electric storage heating is a heating system that utilizes electricity to generate warmth during off-peak hours, typically overnight when electricity rates are lower. These systems then release the stored heat during the day when it is needed. They are designed to capitalize on time-of-use electricity tariffs, making them particularly suitable for areas where alternative heating sources may be less practical or available. Additionally, electric storage heaters contribute to energy bill savings due to their higher energy efficiency compared to other systems.

How electric storage heaters work?

To give you an illustration of how electric storage heaters work, we’ve created a simple step-by-step guide on the process they use:

  1. Off-peak charging: During off-peak hours, typically at night, electric storage heaters draw electricity from the national grid and store it. The electricity heats up the core material, often made from ceramic bricks or similar heat-retaining materials inside the heaters.
  2. Heat retention: Once heated, the core material retains the warmth for extended periods, releasing it as needed within the home.
  3. Heat release: As ambient temperatures drop throughout the day or occupants require more warmth, the stored heat gradually disperses from the heater.
  4. Thermostat control: Modern electric storage heaters come equipped with thermostats to regulate the amount of heat released. This feature enables residents to maintain comfortable indoor temperatures while conserving excess electricity, thereby reducing heating costs. Moreover, these systems typically boast higher energy efficiency compared to alternative heating methods.
  5. Economy 7/ Time-of-use tariffs: EElectric storage heaters often complement special electricity tariffs such as “Economy 7” or similar variations. These tariffs offer reduced electricity rates during off-peak hours when demand is lower, incentivizing users to consume electricity during these periods

Who Qualifies For Free Electric Storage Heating In Scotland?

To qualify for free electric storage heaters and systems under the ECO4 scheme in Scotland, certain criteria must be met. Eligible households and individuals include:

Grant eligibility

  • Homeownership or renting from a private landlord with permission.
  • Household income below £31,000 per year for low-income households.
  • Presence of a child under five years old in the household.
  • Household member over 65 years old, vulnerable, or suffering from specific health conditions.
  • Residency in an area vulnerable to cold living conditions.
  • Energy Performance Certificate (EPC) rating of D, E, F, or G for homeowners; E, F, or G for renters.
  • Grant funding typically prioritizes homes with inefficient energy heating systems or inadequate cavity wall insulation. All homes must undergo assessment to determine eligibility.

Qualifying allowances

  • JSA:
    Income-based Job-Seekers Allowance
  • ESA:
    Income-related Employment and Support Allowance

Qualifying benefits

  • Housing benefit
  • Child benefit

Qualifying credits

  • Child Tax Credits (CTC)
  • Pension Credit Guarantee Credit
  • Pension Credit Savings Credit
  • Universal Credit (UC)
  • Working Tax Credits (WTC)

What if you don't qualify for grant funding?

If you do not qualify for grant funding based on the aforementioned criteria, there are still options available to you through the Government ECO Scheme, specifically the ECO4 Flex options. These alternatives encompass various energy efficiency improvements, such as replacing a gas boiler, obtaining a first-time central heating grant, securing an insulation grant, or acquiring an electric heater grant.

How Do I Apply
For Free Electric Storage Heating
In Scotland?

At Envirohomes Renewables, our mission is to facilitate the adoption of eco-friendly solutions for your home. Our services are underpinned by the Scottish government’s ECO4 funding, and our team excels in installing eco-friendly boilers, solar panels, insulation, and heat pumps. To streamline the application process for these upgrades, we’ve outlined a simple step-by-step guide:

What are the Advantages of Electric Storage Heating?

Electric storage heaters offer numerous advantages for both you and your home, including:

  • Cost-effectiveness: Leveraging off-peak electricity rates, electric storage heaters can significantly reduce energy bills by storing heat during cheaper periods for release during peak hours.
  • Energy efficiency: When utilized correctly, electric storage heaters contribute to energy efficiency by storing and gradually releasing heat, minimizing constant energy consumption.
  • No gas required: Ideal for homes without access to gas lines or for those preferring gas-free appliances.
  • Simple installation: Installation of electric storage heaters is relatively straightforward, particularly with an existing electricity supply
  • Low maintenance: With fewer moving parts compared to traditional heating systems, electric storage heaters require minimal maintenance and have fewer points of failure.
  • Reduced carbon emissions: Utilizing electric storage heaters powered by renewable energy sources can significantly reduce carbon footprints compared to fossil fuel-dependent systems
  • No boiler required: Eliminating the need for a boiler helps mitigate high upfront installation costs, particularly beneficial for homes lacking central heating systems.


The timeframe for implementing energy efficiency improvements varies based on factors such as the type and complexity of the measures, property size, layout, and environmental considerations. While some improvements may require only a few hours to a day for completion, others, such as installing ground-source heat pumps or cavity wall insulation, may necessitate several days to weeks.

The ECO4 grant covers various upgrades, including free boilers, solar panels, air source heat pumps, and home insulation encompassing loft, roof, and cavity wall insulation, as well as draught-proofing. To determine your eligibility for these grants, you can utilize Envirohomes Renewables’ online platform for a streamlined assessment process. Alternatively, you can seek assistance by contacting us at 0141 459 0292, and we’ll guide you through the ECO4 funding application process.
