Solar Panel Grants UK – Light Up Your Savings

The price of solar panels has substantially decreased recently, presenting a more feasible choice for numerous homeowners. Nevertheless, the upfront cost remains quite steep, posing many challenges.

This guide offers a comprehensive look at the primary solar panel grants and financing opportunities in the UK, detailing the process to qualify for these grants.

What Are Solar Panels?

Solar panels are devices designed to capture sunlight and transform it into electricity. They are composed of numerous cells containing photovoltaic materials. 

When these cells are exposed to sunlight, the photovoltaic material generates an electric field across each cell, prompting electrons to move and produce electricity.

The term ‘solar PV’ originates from the fact that these panels are made of photovoltaic cells sandwiched between silicone layers. Solar PV means generating electricity using the sun’s energy. 

While installing solar panels in areas with less consistent sunshine might seem ineffective, modern solar panels can generate electricity even from daylight, not just direct sunlight. Naturally, brighter, sunnier days result in higher electricity production.

Solar Panel Grants UK: What Are They?

Solar panel grants are financial incentives to reduce the cost of installing solar panels. Generally, these grants in the UK are offered by government bodies, but they can also come from utility companies or other organizations. They aim to make solar energy more accessible and promote the shift towards renewable energy sources.

The amount of funding provided by solar panel grants usually depends on the solar installation size, with larger setups receiving more support. These grants might also be allocated based on the installation’s intended purpose, like powering low-income housing projects.

The government has gradually discontinued many of its solar panel grant programs in the UK, with only a few initiatives like ECO4 and LA Flex still active. These remaining programs offer financial assistance to facilitate the installation of solar panels for both homeowners and businesses, making them more budget-friendly.

These government grants represent a segment of a broader strategy to attain net-zero emissions in the energy sector by the year 2050. Alongside solar energy, the government is channeling investments into other forms of renewable energy, including wind and hydropower, to achieve this ambitious environmental target.

Who Can Apply for the 2023 Free Solar Panel Grant?

To be eligible for a free solar PV grant through the Government’s ECO scheme in 2023, an individual must either own their property or rent it privately, obtaining the landlord’s consent for the necessary modifications. Approximately £1.3 billion in funding is available for recipients of certain government benefits. 

The scheme is accessible to around 6.5 million households, and the government aims to implement energy-efficient improvements in 900,000 homes by March 2022. Despite this substantial funding, a large portion remains unclaimed, resulting in many low-income households paying higher energy bills than necessary. 

Homeowners should promptly check their eligibility for a solar panel grant to reduce their energy expenses.

Grants for Solar Panels – ECO4 Initiative

Since its inception in 2013, the Energy Company Obligation (ECO) scheme has been instrumental in helping numerous individuals lower their energy costs and enhance the energy efficiency of their homes. 

This initiative offers free or subsidized energy-saving solutions to low-income households, vulnerable individuals, and those experiencing fuel poverty.

The ECO scheme has implemented over 3.1 million energy efficiency measures across more than 2.3 million homes, leading to an average annual saving of £1000 per household on energy bills.

The scheme is in its fourth stage, ECO4, which started in July and is set to run until 2026. The UK government has allocated an annual budget of £1 billion for this program.

Eligibility Criteria for ECO4 Solar Panel Grants

The ECO4 scheme provides solar panel grants to homeowners, landlords, and tenants aiming to lower their energy bills. These grants cover the installation of solar panels and other renewable energy technologies.

Eligibility for ECO4 includes:

• Homeowners, landlords, and private tenants

• Households with inefficient electric heating systems

• Households receiving income-related benefits

The qualifying benefits under ECO4 are:

• Child Tax Credit

• Income Support

• Income-based Jobseekers Allowance

• Income-related Employment and Support Allowance

• Pension Credit Guarantee

• Universal Credit

• Working Tax Credit

• Child Benefit (under specific thresholds)

The thresholds for Child Benefit eligibility are as follows:

• Single adult with one child: £19,900

• Single adult with two children: £24,800

• Single adult with three children: £29,600

• Single adult with four or more children: £34,500

• Couple with one child: £27,500

• Couple with two children: £32,300

• Couple with three children: £37,200

• Couple with four or more children: £42,000

LA Flex Scheme for Solar Panel Grants

The Local Authority Flexible Eligibility (LA Flex) scheme adds to the government’s Energy Company Obligation (ECO) program. LA Flex facilitates local councils and authorities in broadening the eligibility for ECO scheme benefits within their jurisdictions.

Determining eligibility criteria for the LA Flex scheme falls under the purview of each Local Authority. 

This expansion of eligibility is advantageous, especially for those who do not qualify for the ECO4 scheme, allowing more individuals to access the scheme’s benefits. The extended criteria are designed to prioritize assistance for households most in need.

LA Flex primarily targets two eligibility groups: low-income and fuel-poor households. Low-income households earn below 60% of the national median income, while fuel-poor families spend over 10% on fuel expenses.

How Much Can I Save With Solar Panel Grants UK?

The savings you can achieve with solar panel grants in the UK depend on several factors, including the size and efficiency of the solar panel system installed, the initial cost of installation, and the amount of sunlight your location receives. Here are some key points to consider:

  1. Grant Amount: The specific grant or subsidy you receive can significantly reduce the upfront cost of installing solar panels. The exact amount varies depending on the grant program.
  2. Energy Bill Reduction: Solar panels can significantly lower your electricity bills by allowing you to generate your power. The amount you save depends on your energy usage and the efficiency of your solar panel system.
  3. Location: Solar panel efficiency can vary based on geographical location. Solar panels will produce more electricity in sunnier areas, leading to higher savings.
  4. Size of the Installation: The larger your solar panel system, the more electricity it will generate, potentially increasing your savings.
  5. Feed-in Tariffs or Smart Export Guarantee (SEG): If you generate more electricity than you use, you may be able to sell the surplus back to the grid, providing an additional income stream or credit on your energy bills.
  6. Long-Term Savings: While the initial cost, even after grants, can be substantial, solar panels are a long-term investment. Over time, the savings on energy bills can accumulate, often offsetting the initial cost.
  7. Increased Property Value: Homes with solar panels can have a higher market value, an indirect form of saving or return on investment.

On average, solar panels can lead to annual savings of around £300 on utility bills. Considering the typical lifespan of solar panels, which can be several decades, this means they have the potential to save you thousands of pounds over their lifetime. 

This long-term saving is a significant factor to consider when evaluating the value and return on investment of installing solar panels, especially when combined with the benefits of solar panel grants in the UK.


In conclusion, solar panel grants in the UK, including the ECO4 and LA Flex schemes, offer significant financial assistance to eligible households, reducing the cost of solar panel installation. These grants contribute to substantial long-term savings on energy bills, support the shift to renewable energy, and align with the government’s goal of achieving net-zero emissions by 2050.
