Thinking of Going Solar? Don’t Miss What You’re Entitled To
Let’s get real for a moment: one of the biggest reasons many UK homeowners finally pull the trigger on solar panels isn’t just the long-term savings it’s the support you can get upfront.
Because while solar panels london aren’t as expensive as they used to be, they’re still a decent investment. And the government knows that.
That’s why, as of 2025, there are still some decent incentives floating around some national, some local — and if you don’t know about them, you might be leaving money on the table.
Here’s what’s available, who qualifies, and how to actually claim what’s yours.
First Off: Do Solar Incentives Still Exist in 2025?
Yes but not the way they did 10 years ago.
The generous Feed-in Tariff days are long gone, but the UK still offers meaningful support, mainly through:
- 0% VAT on solar panel systems
- The Smart Export Guarantee (SEG) a way to earn from your excess energy
- Flexible Financing Option depending on where you live
It’s not a free-for-all, but it is a solid financial nudge in the right direction.
1. 0% VAT on Solar Panel Installations
This is the simplest and possibly most overlooked incentive out there.
Since 2022, the government has scrapped VAT on domestic solar panel systems. That means if you’re installing solar on your own home, you pay no VAT at all.
Let’s put that in perspective: on a £8,000 system, that’s £1,600 you don’t have to hand over. It’s automatic, built into your installer’s quote, and doesn’t require any paperwork on your end.
No forms. No waiting. Just a cleaner invoice.
2. The Smart Export Guarantee (SEG)
Think of this one as your system paying you back.
If your panels produce more electricity than you use, that surplus can be exported to the National Grid. Thanks to the Smart Export Guarantee, energy suppliers now pay you for the electricity you give back.
Here’s how it works:
- You’ll need an SEG-licensed energy supplier (most big names are signed up)
- Your solar system must be installed by an MCS-certified installer
- You’ll get paid per kWh of exported energy rates vary by supplier
It won’t make you rich, but over the year, many households earn £100–£200 or more just from exporting unused power.
Some suppliers offer fixed rates, while others offer variable rates depending on demand. It’s worth shopping around once your systems live.
3. Green Mortgages & Financing
Not exactly a grant, but worth mentioning. Some banks and lenders now offer green mortgages basically lower interest rates or cashback if you’re upgrading your home with renewable energy.
They’re particularly helpful if you’re:
- Buying a new home and want solar included
- Re-mortgaging and want to roll solar into the deal
Secondly, MCS, EVPS and HIES accredited Installers like Evergreen Power work with lenders offering solar-specific finance, which can help spread the cost without sky-high interest.
What to Watch Out For
A few quick heads-ups before you go hunting for support:
- You need to use an MCS-certified installer for nearly every incentive or SEG scheme
- Don’t expect cash upfront SEG payments are typically quarterly or annual
- Incentive rules can change so it’s smart to act sooner rather than later
- Some “free solar Croydon” offers you see online? They often come with long lease terms. Read the fine print.
Summary: Solar Support Still Exists You Just Need to Know Where to Look
Here’s the bottom line:
- You automatically get 0% VAT on installations
- SEG lets you earn by exporting extra energy
- Green finance makes go solar more accessible, even if you can’t pay upfront
No, solar isn’t “free” anymore. But with the right setup, it pays for itself and these incentives help you get there faster.
FAQs
1. Do I need to apply for 0% VAT?
Nope. It’s automatic on eligible domestic installations.
2. How do I sign up for SEG?
Once your system’s live, contact an SEG-licensed supplier and provide your installation certificate and meter info.
3. What’s the average SEG rate?
Rates vary most pay between 5p and 15p per kWh. Fixed-rate tariffs are often more predictable.
