Zero bills are not a future promise. They are, says Ivan Castro, already happening. But the question is: how to deliver them at scale?<\/strong><\/p>\n\n\n\n

The UK government’s \u00a313 billion commitment to ‘zero bill’ homes marks a watershed moment The question is how to deliver them at scale for UK energy policy. Energy Secretary Ed Miliband’s Warm Homes Plan<\/strong><\/a> will fund solar panels, batteries, and heat pumps across millions of homes, meanwhile Housing Secretary Steve Reed has championed the Carpenters Yard development in Epping, the world’s largest zero-bills community, as a template for Britain’s housing future. <\/p>\n\n\n\n

The ambition is clear and the market opportunity substantial. By 2030, residential batteries are forecast to exceed one million units, EVs will grow from one to ten million, and heat pump installations will reach 600,000 annually. Ministers envision a nation where homes generate enough power to eliminate electricity bills entirely. <\/p>\n\n\n\n

The question is not whether zero bills are possible, they demonstrably are. The question is how to deliver them at scale. <\/p>\n\n\n\n

Proof of concept: seven years of results <\/strong><\/p>\n\n\n\n

Zero bills are not a future promise. They are already happening. Since October 2019, companies such as Levelise have delivered exactly this outcome through energy flexibility, paying over \u00a32 million directly to more than 5,500 customers by trading their battery storage across energy markets. These aren’t subsidised demonstration projects. They are ordinary homes with batteries, benefiting from infrastructure connecting them to multiple revenue streams. <\/p>\n\n\n\n

The mechanics are straightforward. When electricity is cheap or abundant, batteries charge. When demand peaks and prices spike, batteries discharge back to the grid. This arbitrage reduces bills, but the real value comes from participating in multiple markets simultaneously: wholesale trading, grid balancing services, capacity payments, and local network flexibility. A single home battery can generate revenue from four or five sources in a day. This is a proven seven-year track record of turning household batteries into active grid participants that earn money for homeowners while supporting system stability. <\/p>\n\n\n\n

Why most homes cannot access this value <\/strong><\/p>\n\n\n\n

Here is the challenge facing the government’s ambition: installing a battery does not automatically deliver these benefits. Most residential batteries today sit largely idle during peak demand periods, unable to access the flexibility markets where the value lies. <\/p>\n\n\n\n

Think of it like this: buying a car doesn’t make you a taxi driver. You need licensing, insurance, dispatch systems, payment processing, and regulatory compliance. Similarly, owning a battery doesn’t make you a flexibility provider. You need the infrastructure that connects your asset to the markets. <\/p>\n\n\n\n
