UK solar funding guide
Solar Panel Grants UK
If you are looking for help with the cost of solar panels, it is important to understand the difference between grants, tax relief, export payments, and local funding. Some support may be available, but there is no universal solar panel grant for every UK homeowner.
Last updated: May 2026
Quick answer
There is not currently a dedicated UK Government solar panel grant that every homeowner can claim. However, some households may be able to get help through ECO4, local authority schemes, supplier support, or wider home energy efficiency funding.
You may also benefit from 0% VAT on qualifying solar installations and Smart Export Guarantee payments for exported electricity, but these are not the same as an upfront grant.
Main types of solar support to check
Solar funding can be confusing because different schemes work in different ways. Some reduce upfront cost, some reduce tax, and some pay you later for exported electricity.
| Support option | Type | Who it may help | Important note |
|---|---|---|---|
| ECO4 | Energy efficiency support scheme | Some lower-income households, homes with lower energy efficiency, or eligible households through supplier/local authority routes. | Not everyone qualifies, and solar panels may be part of a wider package depending on eligibility and property assessment. |
| 0% VAT on qualifying installations | Tax relief | Many households installing qualifying energy-saving materials through an installer. | This is not a grant, but it can reduce the VAT charged on qualifying installations. |
| Smart Export Guarantee | Export payment scheme | Solar owners who export unused electricity back to the grid through an eligible supplier tariff. | This is not upfront funding. It pays for exported electricity after the system is installed. |
| Local council or supplier schemes | Local or supplier support | Some households depending on postcode, income, benefits, property type, and local availability. | Availability changes, so check your local council and energy supplier before deciding. |
ECO4 and solar panels
ECO4 is an energy efficiency scheme aimed at improving eligible homes. It is not a simple solar discount for everyone. Whether solar panels are included depends on eligibility, the property, the scheme route, and the assessment.
If you think you may qualify, check with your energy supplier, local council, or a properly accredited provider before relying on any claim made in an advert.
0% VAT on qualifying installations
0% VAT can reduce the cost of qualifying energy-saving material installations, including solar panels in the right circumstances. This is useful support, but it is not the same as a grant because it does not pay for the full installation.
Ask your installer to confirm how VAT is being treated on your quote and whether all parts of the installation qualify.
Smart Export Guarantee payments
The Smart Export Guarantee can pay you for electricity your solar panels export back to the grid. It is useful when comparing solar savings, but it should not be confused with a grant because it does not pay your upfront installation cost.
Export rates vary by supplier and tariff. Your total solar benefit usually depends on both bill savings from using your own solar electricity and export payments for surplus electricity.
Common solar grant myths
Be careful with adverts that make solar funding sound guaranteed. Always check the exact scheme, eligibility rules, installer details, and whether you are signing up for a finance agreement.
Everyone can get free solar panels from the government.
There is no universal UK Government solar panel grant for every homeowner. Some households may qualify for support through specific schemes, but eligibility is limited.
SEG is a solar grant.
The Smart Export Guarantee is not an upfront grant. It is a payment for eligible exported electricity after your system is installed.
0% VAT means the solar system is free.
0% VAT can reduce the tax charged on qualifying installations, but you still pay the installation cost.
Any installer can guarantee grant funding.
Funding depends on scheme rules, household eligibility, property assessment, and whether the installer or supplier is approved for the scheme.
What to check before applying for funding
Before you apply for a scheme or accept a solar quote, check the funding route carefully. A good installer or provider should be able to explain the scheme, eligibility, products, warranties, and what you will still need to pay.
Check whether you are eligible for ECO4 or local authority flexible eligibility.
Ask your council if any local home energy funding is available.
Ask your energy supplier if they offer solar or energy efficiency support.
Check whether your installer is applying the correct VAT treatment.
Compare solar-only and solar-plus-battery quotes before buying.
Check whether the quote includes MCS certification and DNO notification.
Compare Smart Export Guarantee tariffs for exported electricity.
Do not assume a solar advert is a government grant unless the scheme is clearly named.
Estimate your solar savings before applying
Even if you qualify for support, you should still understand the likely system size, yearly savings, payback range, export income, and whether a battery or EV charger could make sense.

Frequently asked questions
Are there solar panel grants in the UK?
There is no universal UK Government solar panel grant for every household. Some people may be able to access support through ECO4, local authority routes, supplier schemes, or other energy efficiency funding depending on eligibility.
Can I get free solar panels in the UK?
Some eligible households may receive funded or partly funded energy efficiency improvements through specific schemes, but free solar panels are not available to everyone. Always check the scheme name, eligibility rules, and installer details.
Does ECO4 cover solar panels?
ECO4 can support energy efficiency measures for eligible households, and solar PV may be included in some cases depending on the property, assessment, and scheme route. Eligibility is not automatic.
Is 0% VAT the same as a solar grant?
No. 0% VAT is tax relief on qualifying installations, not a grant. It can reduce the VAT charged but does not cover the whole installation cost.
Is the Smart Export Guarantee a solar grant?
No. The Smart Export Guarantee pays eligible generators for electricity exported back to the grid. It is not upfront funding for buying solar panels.
What should I do before applying for solar funding?
Check your eligibility, speak to your council or energy supplier, compare quotes, confirm installer credentials, and use a calculator to estimate savings before deciding.
