Solar Panel Grants and Funding in 2025
While the generous Feed-in Tariff scheme ended in 2019, UK homeowners can still access significant financial support for solar panel installations through various national and local schemes. Understanding available grants, eligibility criteria, and application processes helps reduce upfront costs and accelerate your transition to renewable energy.
This comprehensive guide covers all current UK solar panel grants, funding schemes, and financial support available in 2025. From free installations for eligible households to ongoing export payments and local council initiatives, multiple pathways exist to make solar panels more affordable and accessible.
ECO4 Scheme: Free Solar Panels
The Energy Company Obligation scheme is the primary route to free or heavily subsidized solar panels for eligible UK households, funded by major energy suppliers as part of government carbon reduction targets.
What is ECO4?
ECO4 runs from 2022 to 2026, requiring large energy suppliers to fund energy efficiency improvements for low-income and vulnerable households. The scheme targets fuel poverty reduction and carbon emission cuts through measures including solar panels, insulation, and heating upgrades. Unlike previous schemes, ECO4 focuses specifically on the least energy-efficient homes.
ECO4 Eligibility Criteria
To qualify for ECO4 solar panel grants, you must meet several requirements. Benefit eligibility includes receiving Universal Credit, Pension Credit, Income Support, income-based Jobseeker's Allowance, income-related Employment and Support Allowance, Working Tax Credit, Child Tax Credit, or Housing Benefit. Alternatively, households with combined income under £31,000 may qualify.
Your property must have an Energy Performance Certificate rating of D, E, F, or G. You must own your home or have landlord permission if renting privately. Social housing tenants should check with their housing association about available schemes. The property must be suitable for solar panel installation with adequate roof space and structural integrity.
What ECO4 Covers
ECO4 provides fully funded solar panel installation including panels, inverter, mounting systems, and professional installation. Many installations include battery storage if deemed beneficial for your household. The scheme covers all necessary electrical work, certification, and grid connection. Installations come with standard manufacturer warranties and MCS certification for accessing Smart Export Guarantee payments.
How to Apply for ECO4
Contact ECO4-approved installers in your area for eligibility assessment. Many installers offer free home surveys to determine suitability. The Simple Energy Advice website provides guidance and connects you with approved providers. Your energy supplier may offer ECO4 schemes directly, so contact them to check availability.
Be wary of scams. Legitimate ECO4 installers never ask for upfront payments or pressure immediate decisions. Always verify installer credentials through the MCS certification database and TrustMark scheme. If something seems too good to be true, seek independent verification before proceeding.
Smart Export Guarantee: Ongoing Payments
The Smart Export Guarantee provides ongoing income for all solar panel owners by requiring energy suppliers to pay for exported electricity, creating a reliable income stream throughout system lifetime.
How SEG Works
Energy suppliers with more than 150,000 customers must offer Smart Export Guarantee tariffs. You need an MCS-certified solar installation and export meter or smart meter to participate. Suppliers pay for every unit of electricity you export to the grid, with rates and terms varying between providers. Payments typically arrive quarterly or annually depending on your chosen tariff.
SEG Tariff Rates
SEG rates vary significantly between suppliers, making comparison essential. Octopus Energy offers variable rates with their Outgoing tariff reaching 15p per kWh during peak times, plus fixed options around 5.5p per kWh. E.ON Next provides 5.5p per kWh fixed rate. British Gas offers 4p per kWh. EDF Energy pays 3.5p per kWh. Utility Warehouse provides 7p per kWh for their customers.
Time-of-use tariffs like Octopus Outgoing pay premium rates during high-demand periods, typically 4pm-7pm weekdays. These tariffs suit households with battery storage who can store daytime generation and export during peak periods, potentially earning 10-15p per kWh instead of 3-5p.
Maximizing SEG Income
Shop around annually for the best SEG rates as tariffs change frequently. Consider time-of-use tariffs if you have battery storage. Monitor export levels through your smart meter or inverter app to ensure payments match actual exports. Switch suppliers if better rates become available, as you're not locked into long contracts. Optimize system performance through regular maintenance to maximize generation and export volumes.
SEG Eligibility
All solar panel installations need MCS certification to qualify for SEG. Your installer should provide this automatically. Installations must have appropriate export metering, either through smart meters or dedicated export meters. System capacity can range from small domestic installations to larger arrays up to 5MW. Registration typically takes 2-4 weeks after installation completion.
Local Council Solar Grants
Many UK local authorities offer green energy grants, loans, and support schemes to help residents install solar panels as part of local climate action commitments.
Types of Council Support
Council schemes vary widely but commonly include interest-free or low-interest loans for solar installations, cashback grants reducing installation costs by £500-2,000, bulk-buying schemes negotiating discounted rates with installers, and free energy advice and home assessments to identify optimal solutions.
Notable Council Schemes
Greater London Authority periodically runs solar programs for London boroughs. Manchester City Council offers green energy support as part of zero-carbon commitments. Bristol City Council provides renewable energy grants. Edinburgh Council supports solar installations through various environmental programs. Cornwall Council has historically offered solar panel grants, though schemes change regularly.
Contact your local council's environmental or climate change department to ask about current programs. Many councils partner with organizations like the Energy Saving Trust to deliver schemes. Check council websites for announcements about new funding rounds, as schemes often operate with limited funding allocated on a first-come basis.
Regional Variations
Scotland offers additional support through Home Energy Scotland providing free impartial advice, interest-free loans up to £7,500 for renewables through the Warmer Homes Scotland scheme, and enhanced support for rural and island communities. Wales provides Nest scheme for low-income households and advice through Energy Saving Trust Wales. Northern Ireland offers support through NI Energy Advice and periodic grant schemes from the Department for the Economy.
Home Upgrade Grant
The Home Upgrade Grant scheme targets off-gas-grid properties in England, providing funding for energy efficiency improvements including solar panels.
HUG Eligibility
Properties must be off the gas grid, have EPC ratings of D-G, and be owner-occupied or privately rented. Household income requirements typically include receiving certain benefits or earning under £31,000 combined income. The scheme prioritizes homes most in need of energy efficiency improvements.
What HUG Covers
Grants cover solar panels as part of whole-house retrofit approaches, often combined with insulation, heat pumps, and other improvements. Funding extends to £10,000 per property in some cases, with solar panels forming part of comprehensive energy upgrades. Local authorities administer HUG, so contact your council to check scheme availability in your area.
VAT Relief on Solar Panels
Recent VAT changes have made solar panels significantly more affordable for all UK homeowners regardless of income or property type.
Zero VAT Rate
Since April 2022, solar panel installations on residential properties benefit from 0% VAT instead of the previous 5% or 20% rates. This applies to all solar panel installations, battery storage systems, and related equipment installed in or near residential properties. The zero rate saves £300-1,600 on typical installations, immediately reducing payback periods.
Who Benefits
All homeowners benefit from zero VAT regardless of income, property value, or location. The relief applies to new installations and retrofits. Both solar panels and battery storage qualify for 0% VAT when installed together or separately. Ensure installers charge 0% VAT on eligible work and challenge any incorrect VAT charges.
Solar Panel Loans and Finance
If you don't qualify for grants but want to avoid large upfront costs, various loan options make solar panels accessible through manageable monthly payments.
Green Energy Loans
Several providers offer specialized green energy financing. Banks and building societies provide green loans at competitive rates, typically 4-8% APR over 5-10 years. Some lenders offer preferential rates for energy efficiency improvements. Calculate total repayment costs to ensure monthly loan payments don't exceed solar savings, aiming for positive cash flow from month one.
Installer Finance
Many solar installers partner with finance companies offering tailored packages. These typically feature competitive rates of 5-10% APR, terms from 3-15 years, and quick approval processes often within 24 hours. Check for hidden fees, early repayment penalties, and whether interest rates are fixed or variable. Compare installer finance against independent loans to ensure competitive terms.
Interest-Free Council Loans
Some councils offer interest-free loans for energy improvements. Terms extend to 5-10 years with no interest charges, though maximum loan amounts typically cap at £5,000-10,000. Check eligibility as some schemes limit to low-income households while others are available to all residents. Interest-free loans deliver the best financial outcomes when available.
Grants for Specific Groups
Additional support exists for particular household types and circumstances.
Pensioners and Elderly Residents
Pensioners receiving Pension Credit automatically qualify for ECO4 scheme support. The Warm Home Discount provides £150 annual rebate that can complement solar installations. Some councils offer enhanced support for elderly residents through dedicated fuel poverty programs. Age UK provides advice on accessing available support and grants.
Disabled Persons
Households with disabled members may qualify for additional support through Warm Home Discount scheme extensions, local authority disability grants that can contribute to solar costs, and ECO4 priority status in some areas. Contact your council's adult social care or housing department about available support.
Rural Properties
Off-grid rural homes may access Home Upgrade Grant scheme funding, enhanced support in Scotland, Wales, and Northern Ireland for remote properties, and higher grants recognizing additional installation challenges. Rural properties often benefit most from solar due to higher electricity costs and grid resilience concerns.
Social Housing Tenants
Housing associations and councils increasingly install solar panels on social housing properties. Contact your housing provider about solar installation plans. Some associations prioritize tenants with high energy costs or fuel poverty concerns. Tenant participation can sometimes accelerate installation timelines.
Community Solar Schemes
Community energy projects offer alternative pathways to benefit from solar without installing panels on your own property.
How Community Solar Works
Community groups install solar panels on communal buildings like schools, community centers, or churches. Residents invest in the project through community shares or memberships. Returns come through dividends from electricity generation income, reduced energy bills if you use the communal building, and community fund grants for local projects.
Benefits of Community Solar
Community solar suits renters who can't install panels, flat dwellers without suitable roof space, and those wanting smaller investments than full system costs. Projects typically deliver 3-5% annual returns on investment while supporting local renewable energy development. Find schemes through Community Energy England, Community Energy Scotland, or Community Energy Wales.
Application Tips and Advice
Successfully accessing grants and support requires understanding application processes and avoiding common pitfalls.
Prepare Documentation
Gather proof of benefits or income, recent energy bills showing current consumption, property ownership documentation or landlord permission, and current EPC certificate or willingness to obtain one. Having documentation ready accelerates application processes significantly.
Get Multiple Assessments
Contact several ECO4 providers or grant administrators to compare offerings. Different providers may offer varying levels of support or include additional measures. Free home assessments identify optimal solutions for your property. Compare installer credentials and reviews even when accessing free installations, as quality varies.
Understand Obligations
Some schemes require remaining in the property for minimum periods, typically 5-10 years. Grant clawback provisions may apply if you sell within specified timeframes. Understand maintenance responsibilities and ongoing requirements. Check whether grants affect property ownership rights or require repayment under certain circumstances.
Avoid Scams
Be wary of unsolicited contact claiming you've qualified for grants. Legitimate schemes never request upfront payments for free installations. Verify all companies through MCS certification database, TrustMark scheme, and Companies House registration. Don't feel pressured to decide immediately; reputable installers allow time for consideration. Seek independent advice if anything seems unclear or suspicious.
Combining Multiple Support Options
Maximizing financial support often involves combining several schemes and incentives.
Stacking Benefits
You can combine ECO4 scheme funding with Smart Export Guarantee payments for ongoing income, 0% VAT on any additional work or upgrades, local council grants if available for system extensions, and battery storage funding from separate schemes where applicable. Stacking multiple benefits significantly improves financial outcomes.
Example Combinations
A low-income household might receive free 4kW solar installation through ECO4, earn £150-250 annually through SEG payments, save £500-700 annually on electricity bills, and benefit from £300-500 saved through 0% VAT on any additional work. Total first-year value reaches £950-1,450 with ongoing annual benefits of £650-950.
Future Grant Prospects
While current schemes provide substantial support, additional programs may emerge as government climate commitments intensify.
Potential Developments
Watch for expanded ECO schemes beyond 2026, new green home finance initiatives as part of net-zero strategies, enhanced support for heat pump and solar combinations, regional pilot programs testing innovative funding models, and increased local authority schemes as climate emergency declarations drive action. Stay informed through energy advice services and government announcements.
