  • Kicking off trials in Suffolk, with county council offering £15k interest-free loan for residents to kit out their homes with solar panels and a battery
  • Octopus Energy estimates 500,000 UK properties built since 2013 could be eligible to be upgraded to ‘Zero Bills’ standards

Octopus Energy, the UK’s largest energy supplier, is taking its world-first ‘Zero Bills’ initiative to the next level by trialling an upgrade offer for existing homes, allowing more householders across the UK to eliminate their energy bills.

Octopus’s upgrade trials will transform existing homes by installing cutting-edge green tech - a heat pump, a battery and solar panels - bringing them up to Octopus’ ‘Zero Bills’ standard, where customers receive no energy bills for at least 5 years, guaranteed.

The energy supplier is kicking off a series of trials in new homes in Suffolk. The company is teaming up with Suffolk County Council to help more local people benefit from low-carbon tech through the County Council’s £15,000 interest-free Warm Homes Loan.

Suffolk County Council prides itself in bringing pioneering net zero projects to our residents, and we’re excited to be the first local authority working with Octopus Energy on ‘Zero Bills’.

The loan covers the upfront costs of installing solar panels and a battery, allowing Suffolk homeowners who already have a heat pump to embrace low-carbon living while unlocking major savings on their energy bills.

Octopus is reaching out to local Suffolk customers with homes built since 2015, offering them a chance to join the revolutionary trial and take advantage of the council’s funding.

The energy supplier estimates 500,000 UK properties built since 2013 could be eligible to be upgraded to a ‘Zero Bills’ home. Octopus Energy aims to deliver 100,000 ‘Zero Bills’ homes by 2030, and has already rolled out the initiative in Germany and New Zealand, as well as the UK.

Nigel Banks, Zero Bills Director, Octopus Energy, comments:

“Upgrading existing homes is the next step in making energy-bill-free living accessible to more people.

“Thanks to the innovative approach from Suffolk County Council, local authorities can now play a vital role in bringing sustainable, cost-free energy to householders.

“By working together, we can help local people eliminate bills, reduce carbon emissions, and create a model for communities across the UK to embrace a greener future.”

Councillor Philip Faircloth-Mutton, Suffolk County Council’s Cabinet Member for Environment, Communities and Equality, said:

“Suffolk County Council prides itself in bringing pioneering net zero projects to our residents, and we’re excited to be the first local authority working with Octopus Energy on ‘Zero Bills’.

“We appreciate the role we have as local authority to be able to lead, influence and support local residents in as many ways possible to help reduce both their energy bills and their impact on the environment.”

Octopus has already accredited well over 1,200 ‘Zero Bills’ homes through contracts with a number of prominent developers. Accredited homes span affordable and private rent, as well as private and shared ownership.
