To celebrate 20 years! Spin the wheel for your chance to win an exclusive solar offer!
Residential Solar technology has become increasingly appealing to homeowners across the UK, especially along the South Coast, as energy prices rise and environmental concerns grow. In 2025, the question on many minds is: Can you genuinely get free solar panels for your home? The short answer is: yes—for certain households under specific government schemes and subsidies. But “free” often comes with eligibility conditions and trade-offs. This article will help you understand what options are truly cost-free, what qualifies as “free” but with strings attached, and how Save Energy UK can guide you through the process.
When industry or marketing materials advertise “free solar panels,” they’re typically referring to one or more of the following:
Fully funded installations through national schemes such as ECO4 or local Warm Homes grants.
0% VAT on residential solar hardware and installation, which effectively discounts the final bill.
Smart Export Guarantee (SEG) payments that generate passive income from surplus electricity.
Private or charity-funded schemes offering fully funded installs to highly targeted demographics.
Lease or Power Purchase Agreements (PPAs)—no upfront cost, but you pay for energy usage.
It’s important to note that while the upfront installation might cost you nothing, you may still face conditions like eligibility checks, long-term maintenance responsibilities, or revenue-sharing agreements.
The Energy Company Obligation continues through March 2026, targeting low-income households in inefficient properties (EPC grades D–G). Eligible homes may receive full funding for residential solar panels, insulation, or heat pumps, paid directly by Ofgem-registered installers via obligated energy suppliers MoneySavingExpert.com+15eco4.co.uk+15CRG Direct Solar+15elmhurstenergy.co.uk+13CRG Direct Solar+13evergy.co.uk+13evergy.co.uk+2The Renewable Energy Hub+2Homebuilding+2. ECO4 is one of the few sources of genuinely free solar for qualifying homeowners or tenants with sufficient benefits or low income.
This government-mandated initiative ensures energy suppliers offer payments for surplus energy exported to the grid. While it doesn’t reduce installation costs, it can generate an annual return of roughly £80–£170 for typical installations Warm Home Plan.
Backed until March 2027, this tax relief eliminates the usual 5% VAT on solar panel kits and installations—reducing costs by £300 to £1,000 on average .
From April 2025, this £500 million fund is distributed via local authorities to install energy-saving measures and solar PV in low-income households with EPC D–G ratings. Each eligible home can receive up to £30,000, split between insulation and low-carbon technology—absolutely no cost to the homeowner elmhurstenergy.co.uk+7GOV.UK+7Consumer Rights+7.
Local Authority Flexibility (LA Flex) allows councils to extend ECO4-style support to households that don’t meet national criteria. Eligibility, income caps, and EPC thresholds vary by council Energy Saving Trust+15eco4.co.uk+15ecowiseinstallations.co.uk+15.
Active in regions such as Hampshire and West Sussex, this offers group purchasing across select areas. Homeowners commit to installation after securing bulk pricing—while some cost remains, it is substantially lower Shine Solar+2Homebuilding+2CRG Direct Solar+2.
Companies like Solar Panel Funding offer fully funded solar options for very specific groups—typically single parents with chronic health conditions, incomes under £10,000, and high energy burdens The Renewable Energy Hub+2Wikipedia+2Moneyweek+2.
