Solar for all: spread the cost with finance
Solar panels are a great investment - they generate your own electricity and help you reduce your reliance on the grid. If you thought the upfront cost was a barrier, we’ve got great news. You can spread the cost of your Octopus solar panels and/or home battery with a range of finance options. This means that millions of our customers can enjoy the benefits of solar energy without needing to pay everything upfront.

Through our partnership with DivideBuy, you can split the cost of your solar and battery installation into manageable monthly payments. We can connect you with DivideBuy, who offer finance options over 2 or 3 years at a fixed interest rate of 4.9% APR — or over 9-13 years at 9.9% APR. This makes it easier than ever to generate your own power, even if you can’t cover the full cost right away.
And the best part? By installing solar panels, you’ll start seeing huge savings on your energy bills almost immediately. Over time, these savings will help offset the cost of the panels, making this an investment that pays off in more ways than one.

Sunny Savings
Let’s talk about the savings a little more. According to the Energy Saving Trust, a typical household could save between £400 to £600 per year, depending on your energy use and other factors. After several years of saving on your electricity bills, your solar system will begin to entirely pay for itself; typically this takes about 10 years.
But that’s not all - if your panels generate more electricity than you use, you can also get paid for the excess through the Octopus Export Tariffs. This allows you to sell any unused solar energy back to the grid. So, not only do you save on your energy bills, but you also have the opportunity to generate some extra income.

We believe that clean, renewable energy should be within reach for everyone, no matter their income level. By offering a range of financing options, we’re helping to remove one of the biggest hurdles to adopting solar power - affordability. This isn’t just about making energy cheaper today; it’s about securing a greener, more sustainable future for all of us.
There’s never been a better time to make the switch to solar. Not only can you reduce your electricity costs with the right tariff, but you’ll also be doing your part to combat climate change by using clean energy straight from the source.
Join the Solar Revolution
The shift to solar energy is happening faster than ever, with over 1.6 million UK homes already equipped with solar panels.
The sun is the biggest source of energy we have, and using her power for good just makes sense. We’ve already installed thousands of solar panels on homes across the UK.
So, if you’ve been thinking about going solar but weren’t sure if you could afford it, now’s the perfect time to take the plunge. Let’s make cheaper, cleaner energy a reality for everyone, one rooftop at a time.
