Zero bills, zero worries

Zero Bills homes generate more energy than they consume. They achieve this using a combination of low carbon tech – solar PV and a battery – and electric heating.

We’re guaranteeing zero energy bills at Hollymead for at least 5 years – but this’ll be updated over time. In other words, so long as the hardware (solar, battery, and heat pump) is kept in good shape, we’ll never offer a bill on these homes.

Stay in control using our handy, hassle-free app.

To make it as simple as possible, we’ve a Fair Use Allowance – on total electricity across the year. This is set at approximately double the expected usage, so you’re unlikely ever to exceed it unless you’ve very high heating preferences.

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.

If your solar, battery, or heat pump aren’t working as they should, Octopus reserves the right to move the customer to a different tariff (likely our standard variable tariff, Flexible Octopus, or Smart Export Guarantee). But don’t worry - we wouldn’t do this for the short period while the hardware is fixed.

EV charging isn’t included in the Zero Bills allowance, but will be billed separately at Intelligent Octopus tariff unit rates. The rest of the home’s energy needs remain free.

You’ll always be protected by our 5-year guarantee. Zero Bills means exactly that.

You’re free to leave or switch at any time – we’ll never lock you into any kind of agreement with Octopus. (But we’d challenge you to find as sweet a deal anywhere else…)
