Octopus Energy has launched a radical new tariff promising households will pay nothing for their electricity for at least a decade, as Britain braces for soaring energy costs driven by the Middle East conflict.
The scheme, known as Octopus Zero Bills, guarantees zero energy bills for 10 years for homes built with integrated renewable technology, including solar panels, heat pumps and battery storage.
The tariff is being rolled out in partnership with housebuilders and developers, with Octopus aiming to deliver 100,000 Zero Bills homes by 2030. Properties must generate and store their own energy using green technology, thereby eliminating reliance on traditional grid-supplied power.
The launch comes at a volatile moment for energy markets. While a 6.6 per cent drop in bills is locked in for April, forecasts suggest the July price cap could rise by as much as 20 per cent, adding around £332 a year to a typical household’s costs.
Octopus said the scheme represents a fundamental shift in how energy is consumed:
“Octopus Zero Bills is the next generation energy tariff with zero energy bills for the home, for 10 years, guaranteed.”
Homes qualifying for the tariff must be equipped with:
Heat pumps work by extracting heat from the outside air and using electricity to warm homes, offering a cleaner alternative to gas boilers. Although more expensive upfront, government grants can help reduce installation costs.
Octopus argues that combining these technologies allows homes to become self-sufficient energy systems, insulating households from volatile global energy prices.
The company is already partnering with major developers including Vistry Group, Persimmon plc and Bellway to roll out Zero Bills homes nationwide.
A 130-home development in Bedfordshire is set to become the largest site yet under the scheme, while regional builders such as Thakeham, Verto Homes and GS8 are also investing heavily in the model.
Octopus has also demonstrated how quickly such homes can be built, teaming up with Starship Group and the Liverpool City Region Combined Authority to construct a fully functioning Zero Bills home in just two days.
Beyond New Builds
The company says the concept is not limited to new housing. It estimates that around 500,000 UK homes built since 2013 could be upgraded to meet the Zero Bills standard, potentially eliminating energy bills for a significant number of households.
Octopus argues that advances in renewable technology mean the long-held assumption that energy bills will always rise is no longer inevitable.
With energy markets under pressure from geopolitical tensions — particularly disruption to global supplies linked to Iran — the scheme offers a glimpse of an alternative future where households are shielded from price shocks entirely.
