Is It Worth Getting Solar Panels in 2026?
For most households in the South East, the answer is yes. A solar PV system can:
- Reduce electricity bills by up to 80%
- Increase property value by up to 14%
- Provide 30 years or more of clean electricity
- Reduce exposure to rising energy prices
- Improve energy independence
With electricity rates in the South East among the highest in the UK, solar panels offer particularly strong returns across the region.
The Warm Homes Plan (2026)
The Warm Homes Plan is now the government’s flagship home energy initiative. Worth over £15 billion, it aims to:
- Fund solar panels and battery storage
- Provide zero or low interest government backed loans
- Improve insulation and heating systems
- Reduce fuel poverty
What Could You Get?
Full details of the new plan are yet to be released, but eligible households may receive fully funded solar panel systems and solar battery support, low or zero interest loans and combined solar and heat pump funding.
The scheme is set to be rolled out in phases throughout 2026.
Warm Homes: Local Grant
Replacing the Home Upgrade Grant, the Warm Homes Local Grant offers up to £30,000 per household. Funding is split between energy efficiency upgrades (insulation and glazing), low carbon heating (heat pumps) and solar panels.
Eligibility
You must:
- Live in England
- Earn £36,000 or less
- Have EPC rating D-G
- Own or privately rent your home
If you’re unsure about your EPC rating, SolarTherm UK can advise during your survey.
ECO4 – Ending March 2026
The Energy Company Obligation (ECO4) is due to end on 31st March 2026. It has been funding insulation, boiler upgrades, heat pumps and limited solar installations since July 2022. If you qualify, applications should be submitted urgently to your supplier before it closes.
Smart Export Guarantee (SEG)
The Smart Export Guarantee pays you to export surplus electricity generated by your solar panels back to the grid. This is not a grant, it is an export payment scheme.
Key Facts:
- Your system must be installed by an MCS accredited installer and have valid MCS certification
- You need a smart meter that can automatically send half hourly meter readings
- Tariff rates vary by supplier – shop around to find one that works with your energy usage profile
A typical household exporting 50% of generation may earn up to £160 per year. Over 25 years this can easily add up to an additional £2,000-£5,000 on your returns,
Solar Together (Group Buying Scheme)
The Solar Together initiative enables communities to bulk purchase solar panels via council run auctions. Savings can reach 30-35% compared to a private installation. However, not every council offers this and you get no choice on the installer, so you could end up with an installer that has poor reviews or a bad reputation.
As Solar Together works on an economy of scale, installation timelines may be long while you wait for enough people to sign up.
0% VAT on Solar Panels and Batteries
Until April 2027, homeowners pay 0% VAT on solar panels, battery storage, heat pumps and insulation when supply and installation is handled by an accredited installer. This can save up to £2,900 on a solar PV installation and up to £900 on battery storage, depending on system size and brand.
Green Energy Loans
Green Energy Loans are government backed or lender supported financing products designed to make renewable technology – including solar panels and battery storage – more accessible and affordable.
These loans are typically lower interest rates than standard personal loans, offering flexible payment terms that can be offset against savings on your energy bills.
A Green Energy Loan benefits those who do not qualify for existing grants, who want to spread the cost over time and want to be able to plan for their financial future long term.
Unlike grants, loans don’t require upfront capital and can be used in combination with other schemes such as 0% VAT, SEG and the Warm Homes Plan.

Be cautious of:
- Cold callers promising “free solar panels”
- High pressure sales tactics
- Claims that a scheme ends “today”
- Requests for upfront payments with documentation
