Octopus Energy, one of the UK’s largest energy suppliers, and Barratt Redrow, one of the UK’s largest housebuilders, have announced a partnership aimed at delivering homes with no household energy bills for up to 10 years, combining low-carbon building design with integrated clean energy technology.
The agreement brings together Octopus Energy’s Zero Bills tariff with Barratt Redrow’s new-build housing developments, enabling residents to live in homes designed to generate, store, and use their own energy without paying for electricity or heating during the guarantee period.
Launched in 2022, Zero Bills is positioned as the world’s first tariff of its kind. It applies to homes fitted with a heat pump, solar panels, and a battery system, allowing energy costs to be covered for at least five to 10 years, subject to usage conditions.
First sites and wider rollout
As an initial phase, the partners will deliver 54 Zero Bills homes across two developments in Wixams, Bedfordshire, and Tewkesbury, Gloucestershire.
The first properties are expected to be completed in 2026, with further sites already under consideration across the UK.
The partnership follows Octopus Capital’s recent £100 million funding round through its Affordable Housing Fund, which is expected to support the delivery of more than 1,000 Zero Bills homes across England and Scotland.
Octopus Energy says it has already approved more than 5,000 Zero Bills homes through agreements with multiple developers, spanning affordable housing, private rental, shared ownership, and private sale.
The company has set a target of delivering 100,000 Zero Bills homes by 2030 and has expanded the initiative into markets including Germany, France, and New Zealand.
Nigel Banks, Zero Bills Director at Octopus Energy, says, “We’ve been working closely with Barratt Redrow on research trials and can now demonstrate what’s possible when Zero Bills is delivered at scale within new housing developments.
“With solar panels, heat pumps, and EV chargers increasingly standard in new homes, eliminating energy bills is becoming a practical and cost-effective step.”
Oliver Novakovic, Technical & Innovation Director at Barratt Redrow, adds, “By combining our highly energy-efficient homes with Octopus’ Zero Bills approach, we’re helping customers reduce their energy costs to zero while also lowering carbon emissions.
“This partnership shows how innovation in housebuilding and energy can work together to deliver homes that are both sustainable and affordable over the long term.”
