Take a look at our FAQs
How does Zero Bills work?
Zero Bills is made possible through a combination of low carbon devices – battery, heat pump and solar PV – intelligently managed by Octopus tech to keep you warm at no cost.
How long will zero energy bills be guaranteed on my home?
We guarantee to offer Zero Bills for either 5 or 10 years. For new build homes, Zero Bills begins from the point of first occupation. For existing properties which have been upgraded by Octopus to the Zero Bills spec, this begins once the retrofit works are complete.
The length of the guarantee is based on our agreement with your developer or installer.
What, if anything, happens after the guarantee term?
We intend to offer Zero Bills on an ongoing basis, so long as your home’s hardware (battery, heat pump, solar) remains operational.
Is there a limit on the energy I can use?
There’s a Fair Use Allowance on total electricity across the year.
For new build homes, this is set at approximately double the expected usage, so you will only exceed this if you have very high consumption.
For existing homes that have been upgraded to the Zero Bills spec, Fair Use is based on your property's expected consumption and will be communicated to you directly by Octopus.
What if I exceed the Fair Use Allowance?
You’ll be billed at our Flexible Octopus unit rate (still no standing charge) for any electricity imported above the Fair Use Allowance, with billing done on an annual basis.
Is EV charging included in the Zero Bills guarantee?
EV charging isn’t included in the Zero Bills allowance, but will be billed separately at Intelligent Octopus unit rates. The rest of the home’s energy needs remain free.
What happens if the hardware fails?
If your solar, battery, or heat pump aren’t working as they should, Octopus reserves the right to move you to a different tariff (likely our standard variable tariff, Flexible Octopus, and Smart Export Guarantee). But don’t worry - we wouldn’t do this for the short period while the hardware is fixed.
What happens if I move?
You must be living in a Zero Bills accredited home to be eligible for the Zero Bills tariff. If you move to another Zero Bills home, you will simply need to re-register at your new property. If you move to a non-Zero Bills home, you will need to contact Octopus to switch tariffs.
The new occupants of your current property will be eligible for the remaining guarantee length.
What if I want to switch providers?
You’re free to leave or switch at any time – we’ll never lock you into any kind of agreement with Octopus.
