Get instant savings on your energy bill
Make savings on your energy bill from day one with Sunsave Plus — and reduce your carbon footprint at the same time. With no upfront cost.
A typical four-bedroom family home could save £540 every year.
Our calculations
- Our example is a four-bedroom family home in Essex using 4,000kWh of electricity each year with a 6kWp solar panel system and a 5.2kWh battery.
- This system generates 5,950kWh of electricity from solar each year, using 28% at home and selling the other 72% to the grid (earning up to 33p per kWh through the Intelligent Octopus Flux tariff).
- On average, this household pays £112/month on it's electricity bill, but the savings and export income from solar means it falls to -£28/month (so the property is actually now earning money). Taking into account the £96/month Sunsave Plus payments, the household's total outgoing on electricity is now £67/month - a £45/month saving. In a year, this household now spends £804 on electricity instead of £1,344, saving £540.
- We’ve calculated the previous energy bill using the January 2024 Price Cap. With Sunsave Plus, the savings from grid import and export are calculated using the Intelligent Octopus Flux tariff.
- Savings are calculated using System Advisory Model (SAM) which takes into account smart battery controls to maximise export savings.
- This system would also save 1.5 tonnes of CO2 each year, which over its lifetime is equivalent to 32 long-haul flights
Our calculations have been checked and approved by EVPS. It’s a national certification standard that validates how installers calculate energy-saving estimates.
How it works
Your Sunsave Plus solar and battery system will start cutting your electricity bills from day one. Here’s how it works.
- We install your top-of-the-range solar panels and battery at no upfront cost. You’ll pay us with a fixed monthly fee.
- Your solar panels generate electricity throughout the day, even in winter. If you’re not at home to use it, it goes into your battery.
- All the solar-generated electricity you don’t use will automatically be sold to the grid.
- Nothing goes to waste. You either use the electricity or get paid for it. Simple.
- Depending on your roof suitability and where your home is, your energy bills savings may exceed your Sunsave Plus payments. So there’ll be more money in your pocket each month.

Solar works all year round
Solar panels work all through the year — even in the UK! All they need is a bit of daylight. Your solar panels generate the most energy in summer. This is when you’ll sell the most excess electricity to the grid.
Your solar panel output will drop in winter, but won’t stop completely. You’ll just need to top up with electricity from the grid.
Our calculations
- The chart is based on the same typical four-bedroom family home in Essex using 4,000kWh of electricity each year, with a 6kWp solar panel system and a 5.2kWh battery.
- We’ve calculated this electricity generation using EnergyPlus solar irradiance data, plus the orientation and angle of the property’s roof.
Protection from inflation
Even before the energy crisis, electricity prices have increased by 5.5% each year on average since 2000. Nobody can predict the future, but in this scenario we’ve assumed the same inflation going forwards.
With Sunsave Plus, your monthly payments are fixed, so you’re protected against inflation and your savings increase over time.
Our calculations
- Electricity price change taken from ONS Consumer price inflation time series (MM23), showing 5.5% average increase between 2000-2021. Nobody can predict the future but in this scenario, we’ve assumed the same inflation going forwards.
- Using the same typical four-bedroom family home in Essex as an example, a household with a Sunsave Plus system would save over £30,197 on electricity bills over 20 years (this includes electricity bill savings, plus income from exporting electricity to the grid).
- By 2045, this household would pay £919 a year for electricity with Sunsave Plus, and £3,705 without Sunsave Plus.
- After 20 years, the Sunsave Plus payments end and all the electricity generated is free.

Frequently asked questions
What’s Sunsave Plus?
Sunsave Plus is everything you need to go solar, delivered as a 20-year subscription. It includes the design, supply, financing and install of a system tailored to your home, plus ongoing monitoring, maintenance and insurance through the Sunsave Guarantee for the length of your subscription.
How does Sunsave Plus work?
We offer low cost, long-term financing that spreads the cost of your system over 20 years. So instead of paying for a solar system in one go, you make a smaller monthly payment that allows you to save money on your energy bill from day one.
The subscription ends after 20 years, but you’ll keep your system and continue to save on your energy bill.
Our best-in-class kit works with export tariffs like Intelligent Octopus Flux, so you can sell your excess energy to the grid and maximise your savings.
Who is Sunsave Plus for?
Sunsave Plus is a good option for people who want to save on their energy bills with solar, without making a large upfront payment for a system. It also offers security and peace of mind with the Sunsave Guarantee, so you don’t get any surprise costs.
You need to be a homeowner in England or Wales to get Sunsave Plus.
Do I own my system?
Yes. Sunsave Plus isn’t a lease or rental — you own your system from the day it’s installed.
How long do batteries last?
Solar batteries are built to last a long time, although typically not as long as solar panels which work for longer than 25 years. Most batteries last around 10-15 years (our batteries come with a 10-year warranty), so they usually need to be replaced about halfway through the lifespan of your solar panels.
With Sunsave Plus, we’ll provide you with one free out-of-warranty battery replacement, so you don’t need to worry about getting a new battery when your old one stops performing.
What’s the Sunsave Guarantee?
We only use best-in-class kit, and we’re fully accredited by MCS and other relevant industry bodies. The independent experts at Which? have also put us to the test and endorsed Sunsave as a Trusted Trader, demonstrating that we’re one of the highest quality solar installers around.
That said, sometimes things go wrong. And if that happens, you’re covered by the Sunsave Guarantee for the length of your subscription. It includes full system insurance, 24/7 remote monitoring, a free battery replacement, and any parts and repairs that are out of warranty.
What’s included
- 25-year manufacturer’s warranty on panels
- 10-year manufacturer’s warranty on battery and inverter
- one free out-of-warranty battery & inverter replacement
- 24/7 system monitoring so we can see if something’s not working as expected
- troubleshooting and support with any warranty claims
- insurance for damage, theft, third-party liability and any financial losses if the system isn’t working for a prolonged period of time
What’s not included
- panel cleaning
- repair or replacement of bird netting
When can I get Sunsave Plus?
We’re still working on the finishing touches and hope to roll out Sunsave Plus over the next few months. If you’re interested in signing up, join our waitlist and we’ll let you know as soon as it’s ready.
What are the eligibility requirements?
You need to be a UK resident between 18 and 55 years old, an owner of the property, and in full-time employment.
If it’s a joint application, at least one applicant must be in full-time employment and the lead applicant must be an owner of the property.
You won’t be eligible for Sunsave Plus if you’ve been declared bankrupt or received a county court judgement.
Can I end my subscription early?
You can end your subscription early by paying off your balance. You’ll continue to get the benefits of your system, and there are no early repayment fees or penalties.
If you end your subscription early, you’ll no longer be covered by the Sunsave Guarantee.
What 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. While solar subscription is new in the UK, it’s common to transfer a solar subscription when moving home in countries like the US and Germany.
* Subject to acceptance. The new homeowner will need to pass the same eligibility requirements as any new Sunsave Plus customer.
2. Pay off the balance early
There are no early repayment fees or penalties for paying off your balance early. The new homeowner would own the system outright with no further payments, benefiting from energy bill savings.
- 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.
