Themis & Freya
London, January 2024
I’ve already recommended Sunsave to a number of my neighbours who have expressed some interest. Sunsave have just been very, very good, and very helpful. They’ve done exactly what they said they would do; there’ve been no surprises, no hidden costs.
Richard
Hampshire, April 2024
We’re saving about £400 each year, which is great. My main goal through Sunsave Plus was to cancel out my current energy bill, but now the system is actually paying for itself.
Tim
Guildford, June 2024
I got my system three months ago. Since then I have already moved to Octopus and saved £400. This is without me even selling any energy to the grid, it’s just from using my solar panels at home. And this is especially good considering our high usage.

The Sunsave Guarantee explained
By Charlie ClissittCan I end my subscription early?
Even though Sunsave Plus starts as a 20-year subscription, you are free to make a full repayment to end your contract whenever you want - without any fees or penalties.
- For full settlements, the remaining balance would just be the outstanding credit amount (i.e. not any interest or monitoring & maintenance fees you would have incurred had your subscription continued).
- For partial settlements, any repayment you make would be deducted from the outstanding credit amount. The term of your contract with Sunsave will be reduced but your fixed monthly fees will stay the same. This means you’d accrue interest on a smaller remaining balance, and pay less overall.
If you end your subscription early, you’ll no longer be covered by the Sunsave Guarantee.

Sunsave Plus: a flexible way to go solar
By Charlie ClissittWhat happens if I move home?
We know moving home can be stressful, so you’ll have a dedicated Sunsave customer service representative to help you at every step.
We can’t move your Sunsave system, as it’s tailored to your home. But with Sunsave Plus, we have two options that make it simple for you to move.
1. Transfer your subscription to the new homeowner
You can transfer your system to the new homeowner*, in the same way that you transfer a utility contract.
In countries where solar subscriptions have taken off (such as the US and Germany), passing on the contract has proven to be very popular. For example, Sunrun, the US solar subscription provider, sees 98% of their customers who move home during their subscription successfully transfer their contract to the new homebuyer.
*Subject to acceptance. The new homeowner will need to pass the same eligibility requirements as any new Sunsave Plus customer.
2. Pay off the remaining balance
Alternatively, you can include the value of your solar & battery system in the sale price of your home and make a full early repayment either before the sale or using the proceeds from the sale. There are no additional charges or hidden fees for this and you do not need to repay any future interest or monitoring and maintenance fees.
- Research from WWF & Scottish Power found that solar increases the value of a house by 0.5% to 2.0%. This study excludes the impact of batteries which would likely increase value further.
- A Rightmove study found that increasing a home’s EPC rating raised the value of that home. Adding solar to a home typically increases an EPC by one level, and the study found that increasing EPC from D to C resulted in an average increase of 3%, or £11,157.
What are the eligibility requirements?
Your Sunsave Plus application can have up to two applicants.
- The lead applicant must be an owner of the property
- At least one applicant must be between 18 and 60 years old
- Both applicants must be UK residents
How do I know Sunsave is built to last?
We’ve taken careful steps to ensure Sunsave is set up for the long term.
- We’ve raised substantial investment from established venture capital funds that have previously invested in Google, Airbnb and PayPal, and we also have backing from successful investors like industry leader Bill Nussey, author of Freeing Energy, and Stuart Rose, Chairman of Asda.
- We’re authorised and regulated by the FCA to provide solar panels, batteries, installation, insurance, monitoring and maintenance through a monthly subscription.
- We’ve achieved full recognition from all the industry-leading accreditation schemes, including the MCS, HIES, EVPS, and Trustmark. We’re fully approved by the Financial Conduct Authority, and we’re also a Which? Trusted Trader.
- We’re government backed. In May 2023, we received a £200,000 grant from the UK government via its Green Home Finance Accelerator initiative to fund the research and development of our solar subscription. In January 2024, this was followed up by a further £2 million to launch Sunsave Plus.
- We’ve hired a talented team with decades of experience in the solar and energy industries.
As a safety net, the HIES consumer protection scheme provides deposit and payment insurance, as well as an insurance-backed guarantee that protects you in case Sunsave stops trading.
How much money will I save going solar?
With a solar and battery system, you’ll be buying less electricity from the grid. You can also sell any excess electricity to the grid (earning on average £350 per year). Combining these savings, your annual electricity bills can fall by 103%, on average, which means you across a year you actually earn more than you spend.
This might sound too good to be true, but it’s all because of the high performance of modern solar panels and storage batteries, as well as export income. The panels will dramatically reduce the amount of electricity you buy from the grid, and you’ll also earn money by selling your unused electricity to the grid. Octopus Energy's export tariffs have transformed the financial benefit of solar panels, and it's easy to sign up for one.
This 103% figure is based on a household experiencing average UK irradiance with a 4.4kWp solar panel system and a 5.2kWh battery, using 3,500kWh of electricity each year and signed up to the Intelligent Octopus Flux export tariff.
If you sign up for Sunsave Plus, your savings will work a bit differently. But you could have more money in your pocket each month, despite the monthly payments. Find out more about savings with Sunsave Plus.
These figures are all estimates and every household is unique. Your exact savings with a solar and battery system will depend on a number of factors, including how suitable your roof is, where your property’s located, and your annual electricity consumption.
For a better estimate of how much you could save, try our online savings calculator and book a call with one of our friendly solar experts.

Are solar panels worth it in the UK?
By Josh JackmanCan I sell my excess solar energy to the grid?
Yes. Whenever you generate more electricity than you need (or can fit in your battery), you can sell it to the grid through a scheme called the Smart Export Guarantee (SEG).
All UK energy suppliers with over 150,000 customers have to offer a price to households that export renewably-sourced electricity. Smaller energy suppliers can opt in, too.
Your export tariff provider doesn’t have to be the same as your energy provider, but many energy suppliers offer better rates to customers.
The best available rate is currently Intelligent Octopus Flux. It pays up to 29.4p per kWh (on average) and is only available to Octopus customers.
What are the benefits of installing a battery with solar panels?
Adding a battery to a solar panel system means you can store excess electricity that you would otherwise have exported to the grid.
If you’re out during the day and your solar panels are producing electricity, this goes into your battery to use in the evening. Most solar systems have a battery sized according to your property, so it should provide enough electricity for the night before it needs recharging.
A solar battery also works well with time of use tariffs. It allows you to buy and store cheap night-time grid electricity to use later in the day when electricity would normally be much more expensive.
We’ll make sure you are on the best tariff to maximise your solar savings day and night. So you can sit back and enjoy the extra cash.

EPVS is a certification standard that ensures solar PV and battery energy-saving estimates are accurate by validating installers’ processes. Our EPVS Gold rating means we’re best in class for the accuracy of our savings calculations. So when you choose Sunsave, you’ll know that an independent third party has validated the individual energy-saving estimates in your proposal.
The Home Insulation and Energy Systems Quality Assured Contractors Scheme (HIES)
HIES is CTSI-approved Consumer Code that gives you protection for renewable energy installations, including solar photovoltaic panels, batteries and inverters. When you install solar with Sunsave, HIES protects any deposit you’ve made to us in the event that we can’t install your solar system.
