Fraser Jackson and his wife are among the first residents in Britain to benefit from a “Zero Bills” new-build home, where they are guaranteed free energy for at least five years. Their three-bedroom house, located in the Arbour development in Walthamstow, east London, eliminates monthly energy bills through an integrated system of renewable technologies.

Unlike typical new-builds in the UK, which often feature standard brick and uPVC construction, the Arbour homes boast wooden architecture with sustainable design elements. The development includes solar panels, triple glazing, and high insulation standards. Energy generated by the solar array is stored in a battery the size of a suitcase, allowing the household to draw electricity without incurring costs. Excess energy is fed back into the grid, supporting a zero energy bill guarantee. Heating and hot water are supplied by a low-carbon heat pump, and the site contains no gas infrastructure, making it largely self-sufficient.

Jackson, 73, expressed enthusiasm about the arrangement, noting the ongoing novelty of receiving no bills and contrasting his experience with the average annual energy cost in the UK, estimated at around £1,863. Rising energy prices driven by geopolitical tensions and supply challenges have heightened interest in such developments, he said.

A larger Zero Bills community has recently begun occupancy at Carpenter’s Yard near Epping in Essex. This 113-home project, also designed by architect GS8, features shared amenities such as a village shop, community allotments, and access to electric vehicles and bikes. The development includes affordable rental options, with two-bedroom homes priced at approximately £450,000.

Octopus Energy, the company supplying the green technology and backing the Zero Bills tariff, acknowledges that retrofitting existing homes to Zero Bills standards is more complex than constructing new homes to achieve this level of energy self-sufficiency. Hannah McCarthy, head of partnerships for new homes at Octopus Energy, explained that homes are evaluated based on factors such as orientation and local climate to ensure they meet the criteria. Energy use is monitored under a Fair Use policy, set at roughly double the consumption expected from an average household, accommodating typical increases such as electric vehicle charging without voiding the zero bill guarantee.

Octopus Energy plans to expand the program with a target of 100,000 Zero Bills homes by 2030 and has already approved eligibility for around 6,000 properties. Developers investing in the necessary technology face additional upfront costs—approximately £15,000 per home—that are generally passed on to buyers. Industry stakeholders like Jack Brayshaw of Vistry Homes view the concept positively, suggesting that the prospect of eliminating energy bills could add value to properties, especially as energy costs become a significant concern for many households.

Vistry Homes is currently developing a large-scale project at Langley Park in Chippenham, Wiltshire, where over 300 affordable and shared-ownership homes are being built to high energy-efficiency standards, incorporating solar panels and heat pumps. This project is scheduled for completion late next year and represents a growing trend toward integrating zero energy cost models in new residential developments.
