Helping green home upgrades deliver real returns for landlords
London, 20th May 2026 – Octopus Energy, the UK’s largest energy supplier, has partnered with Hammersmith & Fulham Council to offer its groundbreaking Tenant Power tariff to 52 social homes in the London borough.
For years, landlords had little incentive to invest in solar panels or batteries – tenants saw the savings while landlords footed the bill. Tenant Power changes that. It’s the UK’s first green energy tariff where both social housing landlords and tenants share the financial rewards of smart energy tech.
Buildings equipped with solar panels and a compatible battery system can generate their own renewable energy. Any excess energy is stored in the battery and automatically sold back to the grid at peak times, helping to balance the grid and provide a return for landlords.
The result: tenants see their electricity unit rate bills fall by 30% – saving around £200 a year – compared to a standard variable tariff*, while landlords earn revenue, making clean tech upgrades a smart long-term investment**. Adding a heat pump into the mix, as Hammersmith & Fulham Council has done for all 52 properties, could help Tenant Power tenants save even more on their energy bills.
This win-win model removes one of the main barriers to green investment in social housing, paving the way for cleaner, fairer and cheaper energy for all.
Hammersmith & Fulham Council is leading the way as the first local authority in London to roll out the pioneering tariff. The first phase covers 52 homes, with installations already underway and plans to expand further.
Hammersmith & Fulham council homes recently received major energy-saving improvements as part of the council’s wider £10 million programme to make more than 500 homes cheaper to run and more comfortable year-round.
Octopus Energy aims to have 10,000 homes committed to Tenant Power by the end of 2026.
Nigel Banks, Zero Bills Director at Octopus Energy, said:
“Solar panels and batteries should be a no‑brainer for social housing – but until now the economics haven’t worked well enough. “Tenant Power solves this by cutting tenants’ bills while giving social housing landlords a return for investing in green tech.“By partnering with Hammersmith & Fulham Council, we’re delivering more affordable, greener living to social homes in London, making a real impact on communities and people’s pockets.”
Cllr Frances Umeh, Hammersmith & Fulham Cabinet Member for Housing and Homelessness, said:
“Upgrading our homes with modern, energy-saving improvements is a practical way we can help residents cut bills and stay warm.
“These works will have a lasting impact by creating healthier homes and improving comfort for our residents. We’re determined to make Hammersmith & Fulham the best place in Britain to live in a council home, and this programme and investment is a major step towards that goal.”
Richard, Tenant Power customer from Halifax, said:
“I love that my bills are lower thanks to Octopus’ initiatives – the process was quick and easy, and it really makes a huge difference.
“It’s a bonus knowing I’m making the most of the sunshine with solar panels, and doing something good for the planet too.”
The news comes as interest in low carbon tech surges, with households looking to escape energy market volatility driven by the Middle East conflict. New data from Octopus Energy shows heat pump sales up 103%, solar panel sales up 78%, and EV charger enquiries up 42%, as more Brits try to boost their energy independence.***
