What is a home battery storage tariff?
A home battery storage tariff gives you different electricity prices at different times of day, so you can charge your home battery when it’s cheapest and use that stored energy later.
Charge Power is our smart, two-rate tariff designed especially for homes with a battery. You’ll get cheaper electricity between 12am and 5am, so you can charge your battery overnight at a low rate. Then you can use that stored energy during the day, helping you save money and use your battery more efficiently.
Get even more with the Smart Export Guarantee
The Smart Export Guarantee (SEG) pays you for any electricity you export back to the grid. That means you can earn money from the extra renewable electricity you generate — for example, from your solar panels or your home battery.
Frequently Asked Questions
What do I need to switch to your home battery tariff?
To join our home battery tariff, you’ll need to:
- Have a home battery or solar and home battery system
- Be an existing British Gas customer
- Have an online account
- Have a smart meter set up to send half-hourly readings
- Pay by fixed direct debit
How do I schedule my home battery?
Most battery management apps let you set schedules, so your battery automatically charges during the off-peak hours, and discharges during the peak hours. This means you can benefit from the cheaper electricity and maximise your savings without having to manually programme your battery. Please contact your app provider if you need help setting this up.
I don’t have a home battery yet, can I still sign-up for Charge Power?
We’d recommend signing up for Charge Power once your home battery’s been installed.
How do I get a home battery?
Our home battery tariff works with all battery manufacturers, if you don’t have a home battery yet our friends at Hive can help you. Control everything through the Hive app plus get the free Solar Saver offer and save up to 25% off your electricity usage in your first year.5
Can I use the cheaper off-peak times for other things?
Yes. The other great thing is, you’re not just limited to charging your home battery during those cheaper off-peak hours. Any electricity you use during those hours will be charged at the lower rate too.
Does this battery tariff work with Economy 7?
Customers who have a smart Economy 7 meter can switch to Charge Power through their online account. Unfortunately, Charge Power isn’t available to customers that have a standard Economy 7 meter.
Can I sign up for a SEG tariff as well as a battery tariff?
Yes, as a British Gas energy customer you can sign up for our best SEG tariff Export & Earn Plus which pays five times our standard rate.4 You’ll need a solar and battery installation to be eligible. You can apply for SEG online.

Yes, if you have a smart meter you can join PeakSave and enjoy half-price electricity every Sunday 11am to 4pm.
Do I need an electricity smart meter to sign-up for this battery tariff?
A smart meter tells us exactly when you’re using your electricity. We need to know how much energy you’re using during the day and during the cheaper night-time hours so that we can give you an accurate bill. Without a smart electricity meter, you won’t be able to get the lower unit rate at night. You can arrange a smart meter installation for free in your online account.
Do I need a smart gas meter to sign up for this tariff?
You only need a smart electricity meter for the Charge Power tariff. But if you have a gas supply in your home, we’d always recommend having a smart gas meter. If you’d like one installing, we can fit one for free. Just log in to your online account to book an appointment.
I have an electricity smart meter, why isn’t the Charge Power battery tariff showing in my online account?
It could be because your smart meter isn’t working properly, or your meter was installed by another supplier and isn’t communicating with us. Chat online with one of our friendly advisers and we’ll look into this for you.
What happens if my smart meter stops working after I sign up for Charge Power battery tariff?
If your smart meter stops sending us readings, we’ll estimate your electricity usage during the off-peak period. Please get in touch with us if this happens so we can work out what’s happening and fix your meter.
What happens if I move home while I’m on this battery tariff?
We’ll need to check that you have a battery and smart meter at your new home. Get in touch and we’ll look into signing you up for a home battery energy tariff again.
What if I want to switch tariff?
You can switch to any of our other fixed tariffs for free at any time. Exit fees only apply if you want to move to another supplier, or switch to a variable tariff with British Gas.
Does the battery tariff work with electric vehicles?
Yes it does. You can sign up for Charge Power if you have a home battery and electric vehicle and use the off-peak period to charge your battery and EV.
What’s the difference between the EV and battery tariffs?
Our EV Power tariff is available to customer who have an electric vehicle only. Our Charge Power tariff is available to customers who have a home battery. If you have an EV and home battery you are eligible for our Charge Power tariff.
