FAQs

ZERO BILLS HOMES FOR DEVELOPERS

How can my development qualify as a Zero Bills Homes site?

Your homes must include solar PV, heat pumps and battery systems that meet the Octopus Zero Bills technical specification. AlphaESS provides pre-approved systems and full documentation to support compliance. EV chargers are not included in the Zero Bills and will incur a separate charge.

What is the minimum battery installation size for Zero Bills Homes?

For Octopus "Zero Bills" homes, the minimum battery size is typically 9.5 kWh, with a larger 13.5 kWh option also available, depending on the property's size and usage. These are paired with a 9-10 kW solar system to meet the home's energy needs, excluding EV charging.

How does Octopus guarantee zero bills for homeowners?

Octopus Energy guarantees zero energy bills for five years under the Zero Bills tariff, based on predicted performance and system integration.

Can the Zero Bills model be scaled to multi-plot developments?

Yes. AlphaESS systems are modular and scalable, suitable for everything from single homes to full housing estates, and Octopus support multi-home new-build developments.

How does this benefit property valuation?

Homes with no energy bills and strong energy ratings are highly attractive to buyers and mortgage providers, potentially commanding a higher resale value.

What support is available for developers?

AlphaESS UK provides design assistance, system supply, installer training, commissioning, and post-installation monitoring to ensure smooth handover and performance assurance.

* Residents do not pay a penny for the energy their home uses, and there are no standing charges for at least 5 (but usually 10) years. There is a generous fair use allowance, which is the amount of energy usage included in the guarantee (set at roughly double the average household usage). The only exception is that electric vehicle charging is billed separately at the Octopus super low Intelligent Octopus Go rate, which automatically charges your car at the cheapest rates
