Completely free solar panels are still available in 2026, but only through ECO4, and only if your household receives qualifying benefits. Everyone else pays something, though 0% VAT and Smart Export Guarantee payments can cut your net cost significantly. The old "rent your roof" schemes are gone. Here's what actually exists now and whether you qualify.
Yes. But not in the way Facebook ads suggest.
You've probably seen posts claiming anyone can get solar panels installed for nothing. That's not how it works. The "free solar panel" schemes from the early 2010s, where companies installed panels on your roof and kept the Feed-in Tariff payments, ended years ago. Those deals made the installer rich and left homeowners with panels they didn't own and couldn't remove without permission. Good riddance, honestly.
What does exist in 2026 is ECO4, a government obligation scheme that forces energy suppliers to fund energy efficiency measures for low-income households. Solar panels are one of those measures. If you qualify, the installation is fully funded. You own the panels. You keep all the electricity they generate. No catch, no roof rental agreement, no strings.
The key distinction: "free" solar panels in 2026 means government-funded through a specific scheme with strict eligibility criteria. It doesn't mean free for everyone.
So if you're a homeowner on Universal Credit with a south-facing roof, you might genuinely pay nothing. If you're a homeowner earning £50,000 with no qualifying benefits, you're paying for your panels, though there are ways to reduce that cost substantially. We've broken down what solar actually costs without grants if you want the full picture.
Three routes exist right now. One can cover the full cost. The other two reduce what you pay.
ECO4 is the big one. It's an obligation on large energy suppliers (British Gas, EDF, OVO, E.ON, and others) to fund energy efficiency improvements in eligible homes. Solar panels qualify as a measure, though they're typically installed alongside insulation rather than as a standalone measure. The scheme runs until December 2026.
No fixed grant amount here. The supplier covers whatever the installation costs. A typical 4kW domestic system worth £6,000 to £7,000 could be fully funded.
One thing most guides won't tell you: ECO4 installations prioritise homes with poor EPC ratings. If your home is already rated C or above, you're unlikely to get solar through this route even if your income qualifies. The scheme targets the worst-performing homes first, which makes sense from an energy efficiency standpoint but frustrates people in decent homes who happen to be on low incomes.
This newer scheme works through local authorities rather than energy suppliers. Funding amounts vary by council, and solar panels are included as an eligible measure in some areas. Whether your council offers solar specifically depends on their local priorities and supplier agreements.
We've written a full guide to the Warm Homes: Local Grant that covers what's available in different regions. The scheme runs until 31 March 2028, so there's more runway here than ECO4.
This isn't a grant. It's a tax relief. But it saves real money.
Every domestic solar installation in the UK currently carries 0% VAT instead of the standard 20%. On a £6,500 system, that's £1,300 you're not paying. It applies automatically, your installer shouldn't be charging you VAT at all. If they are, challenge it. The relief runs until 31 March 2027.
Also not a grant, but it offsets your costs over time. Any electricity your panels generate that you don't use gets exported to the grid, and your energy supplier pays you for it. Rates vary wildly. Octopus Energy's Agile Outgoing tariff can pay over 15p/kWh at peak times. British Gas pays around 12p. Some smaller suppliers offer as little as 3p.
Over 25 years, SEG payments on a 4kW system could total £3,000 to £5,000 depending on your tariff and how much you export. Not free panels, but a meaningful return.
Right, so here's where most people's hopes get dashed. The eligibility criteria are specific.
For ECO4, you need to tick two boxes simultaneously:
That second requirement trips people up. If you've never had an EPC done, or yours has expired, you'll need a current one. They cost around £50 to £120 depending on your area and property size.
For Warm Homes: Local Grant, eligibility varies by local authority. Some mirror ECO4's benefit requirements. Others use a broader definition of fuel poverty or target specific postcodes. Your council's website will have the current criteria, or you can check through our eligibility tool.
And for the 0% VAT relief? Everyone qualifies. No income test, no EPC requirement, no forms. It just applies.
£1,200 to £7,000 in year one, depending on which route you take.
Let me break that down properly. A typical 4kW solar panel system in the UK costs between £5,500 and £7,500 installed, according to MCS data. Here's what each funding route saves you upfront:
| Route | Upfront saving | Who qualifies |
|---|---|---|
| ECO4 (fully funded) | £5,500–£7,500 | Benefits recipients, EPC D–G |
| Warm Homes: Local Grant | Varies by council | Varies by local authority |
| 0% VAT relief | £1,100–£1,500 | All domestic installations |
Beyond the upfront cost, solar panels cut your electricity bills by £500 to £900 per year on average, depending on your system size, roof orientation, and how much electricity you use during daylight hours. A south-facing roof in southern England generates more than a west-facing roof in Newcastle. Obviously.
Add SEG payments of £100 to £200 per year, and a typical system pays for itself in 8 to 12 years if you paid full price. If you got it free through ECO4, every penny of savings is pure profit from day one.
One thing worth considering: adding a battery roughly doubles your self-consumption rate, which means more bill savings but also more upfront cost. Batteries aren't typically covered by ECO4, so that's usually a separate purchase.
The process depends entirely on which scheme you're applying through.
For ECO4, you don't apply to the government directly. You apply through an installer or managing agent who's registered with your energy supplier's ECO4 programme. The steps look like this:
Honestly, step 2 is where most people get stuck. Not every MCS-certified installer participates in ECO4. The margins are lower for them compared to private installations, so some don't bother. You might need to contact 3 or 4 companies before finding one that's actively taking ECO4 referrals in your area.
For Warm Homes: Local Grant, contact your local authority directly. Some councils have online application forms. Others use managing agents. The process is less standardised than ECO4 because each council runs their allocation differently.
For the 0% VAT route, there's literally nothing to do. Any MCS-certified installer will automatically apply the zero rate. If you want to compare what you'd actually pay, our guide on solar panel installation costs and process has current pricing from multiple installers.
This sounds like a trick question. Free is obviously better, right?
Not always.
Here's the honest bit. ECO4 installations are fully funded, which is brilliant. But you don't get to choose your installer, your panel brand, or often your system size. The scheme funds what's deemed appropriate for your property based on the installer's assessment. You might get a 3.5kW system when your roof could handle 5kW. You might get budget panels with a 10-year warranty rather than premium ones with 25 years.
If you're paying yourself (with the VAT relief bringing costs down), you choose everything. Panel brand, inverter type, system size, installer reputation. You can specify Tier 1 panels, add optimisers for partial shading, and size the system to match your actual consumption.
So here's my take: if you qualify for ECO4, take it. A free 3.5kW system is infinitely better than a 5kW system you can't afford. But if you're on the borderline, earning just above the benefit threshold, and you can stretch to £5,000 to £6,000 after VAT relief, a self-funded system with better components might serve you better over 25 years.
There's a middle ground too. Some households qualify for partial funding through Warm Homes: Local Grant, covering perhaps 50% to 75% of the cost. That lets you top up the difference and still have some say over specification.
Whatever route you take, make sure your installer is MCS-certified. It's a legal requirement for SEG eligibility, and it's the only way to ensure your installation meets safety standards. We've covered how solar panels actually work separately if you want to understand the technology before committing.
