Charge up on cheap energy

The households under the most pressure from rising bills have had the least access to the technology that lowers them. Going solar meant a suitable roof and thousands of pounds upfront, so the savings went to the people who needed them least. Sunsave Home Battery Plus needs neither.

Is a home battery right for you?

We’ve launched Sunsave Home Battery and Sunsave Sona to help homes that can’t go solar take control of their energy bills.

Introducing Sunsave Home Battery and Sunsave Sona

I did think about getting solar panels before, but because of the upfront cost, it just wasn't possible.

I've been really happy with the service. Everybody's been friendly, and I get quick replies.

I would definitely recommend Sunsave to other people. I'm very happy with my system, and the Sunsave team has been great. I've got no complaints at all.

Tony, a project manager in Bedfordshire, signed up to Solar & Battery Plus in 2024. We asked him what the process was like, why he wanted to go solar, and how much he's saving on his electricity bills.

Customer story: Tony

I didn't feel under pressure to sign a contract. I got the information, then I had my own time and space to think about whether I wanted to go ahead.

If you're concerned about roof space or the orientation of your roof, I would definitely explore the battery option. It's a great way to get into green energy.

The communication with Sunsave stands out. I like that I know who to contact, and that I know I'll get a response.

University lecturer Riaz and his family live in south Manchester. He signed up to Home Battery Plus in May 2026, so we chatted with him about the process, why he wanted a battery, and how much he expects to save on his electricity bills.

Customer story: Riaz

What I liked about Sunsave was it was based on real information, not the average for the nation, region, town, or city.

For anybody who, like myself, didn't know what to expect, that's exactly the sort of sales support you need, rather than pressure selling.

I'm delighted with what they're offering me and everybody else, and I'm looking forward to the savings.

Michael lives in Crewe, and had his Home Battery Plus system fitted in July 2026. While it was being installed, we talked to him about the process, why he wanted a battery, and how much he expects to save on his electricity bills.

Here's what underwriting actually involves

We think careful automation is good for everyone

It all starts with cleaner data

We're asking for far fewer income documents

We've found a smarter way to verify home ownership

We're making our solar finance faster and fairer

How we cut underwriting decisions from days to seconds

If you can't get solar, you can still save a lot of money with a home battery, especially when it's paired with the right tariff

Breaking down the cost barrier

Customers want more control over their energy – not just what they pay, but how they use it.

Two simple tariffs designed for saving

This initiative from British Gas will give more people affordable access to clean energy technology that can really lower their bills.

Sunsave has partnered with British Gas to help more homeowners take control of their energy bills.

We’ve launched a Home Battery package with British Gas

The government has launched the Warm Homes Loan Scheme to provide cheaper loans for home energy tech – and we're an approved lender on the scheme and a certified installer.

Energy bills have been high for years, and are expected to rise even further in January 2027. Tech like solar panels, batteries, and EV chargers can save households hundreds of pounds per year, but their upfront costs are high.

This scheme helps make them more affordable – and with Sunsave, you can get a low or zero-interest loan, choose the length of the contract, and pay it off (in full or in part) whenever you like, with no penalties.

The government is lowering the cost of borrowing

Here's how the scheme works: firstly, the government gives approved lenders a grant for each loan they hand out.

This grant is worth up to 20% of the loan. The lender must then use this money to lower the interest rate on the loan."Warm Homes Loan Scheme – Scheme Rules", UK government, 2026, p. 20

So it's just like a normal loan – only cheaper. In this way, the government makes it more affordable for households to get home energy tech.

The aim is to take up to five percentage points off each loan's interest rate – so a loan that would've previously come with an 8% interest rate could now have a 3% rate.

You'll also see some shorter loans' interest rates fall to 0%, though the minimum loan length is three years.

The scheme is part of the government's £15 billion Warm Homes Plan, which aims to put solar panels onto three million more homes by 2030.“Warm Homes Plan”, UK government, 2026, p. 26

For more information, read our full guide to the scheme.

Energy is an everyday essential that must be affordable for everyone. These government-supported loans will help families across the UK upgrade their homes with no upfront costs to make them warmer and cheaper to run.

You can get a low or zero-interest loan from us

Since we're an approved lender on the scheme and a certified installer, you can get a low or zero-interest loan from us – and we'll carry out your installation.

This means you'll only have to deal with one company, from your quote to your final payment, which should create a much smoother process for you.

We provide loans that cover either solar panels, a home battery, or both.

The scheme imposes a £15,000 limit on solar panel loans, and another £15,000 cap on home battery loans – but that should be more than enough for most households.

A typical 4.9 kilowatt-peak (kWp) solar panel system in the UK costs around £8,000,"Solar PV cost data", Department for Energy Security and Net Zero, 2026 and a 10kWh battery is priced at about £4,000. To learn more, read our guide to solar panel costs.

And if you already have a system, you can use the scheme to add a battery or more panels.

You'll own your system from day one and start saving straight away – and we provide every Sunsave system with long-term protection.

High upfront costs are the biggest barrier to adoption of home energy tech like solar and batteries, which are among the most effective ways to cut household energy bills. When we made it easy to get low-carbon tech with nothing to pay upfront, homeowners responded with huge interest.
But for many, the cost of borrowing was still too high. This scheme tackles that head on, allowing us to offer low or zero-interest finance that puts one of the most effective ways to cut energy bills within reach of almost every UK homeowner.

You choose how long you have to pay

With Sunsave, you can choose a loan term of 3, 10, or 20 years. This allows you to balance how much you want to pay monthly with your overall cost.

If you opt for a shorter-term loan, your monthly payments will be higher, but you'll pay less in interest.

And if you choose a longer term, your overall costs will be higher, due to the interest payments – but you'll pay a lower amount every month, which could mean your energy bill savings are greater than your monthly payments – so you make a net saving from day one. 

Since the government has capped grants at 20% of the loan amount, it's not always possible to cut a full five percentage points off your interest rate on a longer-term loan.

You can also pay off your loan early (in full or in part) for free, with no penalties – whenever you like.

Who can get one?

You may be able to qualify if you own and live in the home you want to upgrade, or if you’re its private landlord.

You'll also need to pass our standard credit and affordability checks, as with any loan.

There are no extra eligibility criteria, meaning that unlike some solar panel grants, you don't have to be a benefit recipient or live in an energy-inefficient property to qualify.

The scheme covers the whole of the UK, but we can only hand out loans in areas where we also install. We currently cover all of England and Wales, and the south of Scotland.

It's simple to apply

To apply via Sunsave, just take these quick steps:

Tell us about your home – we'll design a system and give you a quote

Go through a quick eligibility check – we'll check you're eligible, and that it's affordable

Sign your loan agreement, plus a short government declaration

Agree an installation date, and watch our MCS-certified team install your system

We've made the process as simple as possible, helped by the fact that we'll be your lender and installer.

Signing the government declaration confirms that you won't get two public grants for the same equipment (unless permitted), and that you're not using the loan to replace an existing renewable system.

It also allows the government to send someone to inspect your installation, as an anti-fraud measure. They'll always ask for your permission to visit.

You'll have long-term protection

Whichever package you pick, all Sunsave systems come with long product warranties and insurance-backed workmanship guarantees.

And if you choose Solar & Battery Plus on the 20-year term, you'll get the Solar & Battery Guarantee, which comes with free out-of-warranty replacements, 24/7 monitoring, downtime credit, and all repairs included.

Your system will be insured by Aviva against damage, fire, and theft.

The scheme also requires your installer and system to be MCS-certified, which should ensure that your equipment is safe, works as it should, and is built to last.

Is a Warm Homes loan right for you?

If you want to get solar panels, a battery, or both, but you're put off by the upfront cost or the price of borrowing, the Warm Homes Loan Scheme could be a great solution.

With Sunsave, you can get a low-interest loan over 3, 10, or 20 years, with long-term protection and the ability to pay it off early (in full or in part) for free, with no penalties – whenever you want.

The government intends to provide up to £300 million of funding, but with grants handed out on a first-come, first-served basis, it's unclear how long the scheme will be around.

If you'd like to see the savings you could get from a solar & battery system – or a home battery system – just answer a few questions below, and we’ll provide an estimate.
