Octopus Energy Social Housing Tariff Guide 2026

What is the Octopus Tenant Power Tariff?

Octopus Energy launched the Tenant Power tariff in May 2025 to solve a long-standing challenge in the social housing sector. In traditional renting setups, landlords had to pay the high cost of installing green technology on roofs, but only tenants enjoyed the benefit of lower energy bills. This split incentive meant many housing associations and local councils struggled to justify retrofitting their housing stock.^[1]

Tenant Power creates a shared renewable energy model. Social landlords fit solar panels and a home battery linked to Octopus Energy software. When the sun shines, the property generates clean electricity for the tenant to use. Any unused power goes into the battery, and Octopus automatically manages when that stored energy is exported to the grid.

The key difference between Tenant Power and standard variable tariffs comes down to price structure. Standard variable tariffs are subject to Ofgem's price cap, which limits energy rates and standing charges, not total bills. For 1 October to 31 December 2026 in Great Britain, the illustrative annual dual-fuel Direct Debit bill at typical consumption is £1,723; your actual bill depends on how much energy you use. Tenant Power gives qualifying tenants a guaranteed discount of 25% to 30% off standard variable electricity unit rates.

Smart technology powers this entire setup behind the scenes. Octopus Energy uses its Kraken platform to track household energy generation and battery storage in real time. Kraken controls when to charge the battery during cheap off-peak hours and when to export power back to the national network when demand is high.

It helps to distinguish Tenant Power from the Octopus Zero Bills initiative. Zero Bills guarantees zero energy bills for 5 to 10 years on select new-build social housing constructed to top energy standards, such as Sovereign Network Group's Nexa Fields project in Exeter or Clarion Housing Group's Hollymead Square development in Essex. Tenant Power, on the other hand, is designed for existing or retrofitted social homes, giving tenants a direct unit-rate discount rather than a total bill waiver.

How It Works for Social Housing Tenants

For households living in qualifying properties, Tenant Power offers a direct reduction in everyday running costs. Tenants receive a fixed discount off standard variable electricity unit rates, typically 25% to 30%, with the rate agreed case by case for each scheme. Octopus's own example is a 25% discount saving around £200 a year on their electricity bills, based on October 2025 price cap rates rather than a 2026 outcome.

Savings increase significantly if your landlord fits a heat pump alongside solar panels and a battery storage system. Octopus estimates average savings of £432 a year for a home with solar, a battery and a heat pump replacing gas heating, again at October 2025 standard variable rates. Your own saving will depend on your scheme's discount and how you use energy.

A central feature of the tariff is fair distribution across housing developments. The unit rate discount is identical for every tenant in a participating scheme. Whether your home sits directly under a main solar array or receives slightly less sunshine due to roof orientation, your percentage discount remains exactly the same.

Tenants do not need to fill out complex application forms or organise system installations themselves. Your housing association or local council sets up the scheme and fits the hardware. Once the equipment is active, you simply switch your electricity account to Octopus Energy and select the Tenant Power tariff to start getting the discounted rates.

Tenant Power focuses on electricity unit rates. If your property uses gas for heating, your gas supply stays on a standard variable or fixed energy tariff, unless your landlord replaces the gas boiler with an electric heat pump. Your electricity charges appear on your Octopus Energy bill. You can keep your gas tariff with any supplier, with gas billed separately under that tariff.^[1]

Joining Tenant Power does not affect your rights to state support schemes. Eligible households can receive the £150 Warm Home Discount alongside their tariff savings. Most receive it automatically, but Scottish Broader Group customers must apply to their supplier.^[2]

How It Works for Housing Associations and Landlords

Social housing providers face tough targets to improve home energy efficiency and lower carbon emissions across their portfolios. Before Tenant Power, installing clean technology required substantial capital spending without any direct financial payback for the housing association.

Tenant Power changes this balance by creating a commercial return for landlords. When rooftop solar panels generate excess electricity during daytime hours, that power charges an Octopus-optimised battery. When national grid demand peaks in the evening, Octopus automatically exports that stored energy back to the grid.

Landlords receive export payments for supplying clean energy back to the network during high-demand periods. This revenue stream gives housing associations a clear return on investment, helping to offset the initial purchase and maintenance costs of the hardware.

Housing providers can take the income earned from grid exports and reinvest it into further property upgrades. This creates a practical cycle for funding additional insulation, heat pumps, or solar panels across homes that have not yet been retrofitted.

The scheme fits directly alongside government retrofit funding programmes. The Warm Homes: Social Housing Fund (formerly SHDF Wave 3) allocated £1.29 billion, alongside a £295 million top-up for 2026/27, to help English social landlords upgrade homes below EPC Band C through to September 2028. Combined with the broader £15 billion Warm Homes Plan launched in January 2026, housing associations can pair public grant funding with Tenant Power export revenue to speed up retrofits.

Eligibility and Property Requirements

To access the Tenant Power tariff, a property must meet specific equipment and tenure criteria. Because the tariff relies on automated energy trading and on-site generation, standard homes without green technology cannot sign up.

Heat pumps are optional. Octopus's highest savings estimate, £432 a year at October 2025 rates, assumes a smart heat pump added to the solar and battery setup and replacing gas heating.

Individual tenants cannot sign up for Tenant Power on their own initiative. Private renters and buy-to-let landlords are currently excluded from the tariff, as it calls for a multi-property partner agreement between Octopus Energy and a registered social housing provider.

Which Housing Providers Are Currently Participating?

Octopus Energy works with several leading housing associations and local authorities across Great Britain to roll out Tenant Power and related clean energy initiatives.

Octopus Energy aims to scale the scheme from over 1,000 tenants in initial trial phases to more than 10,000 committed social homes by the end of 2026.

Social landlords looking to join can partner with Octopus Energy directly or arrange hardware retrofits through integrated industry specification frameworks, such as Wienerberger RoofSpec+, which integrated Tenant Power compatibility in May 2026.

Are There Alternatives to Tenant Power?

If you live in private rented accommodation, or if your social landlord has not yet joined the Tenant Power scheme, you cannot access this specific discounted tariff. However, Octopus Energy offers several standard variable, fixed, and smart tariffs to individual UK energy consumers.

Flexible Octopus is the supplier's standard variable tariff. For the quarter running from 1 October 2026, paying by Direct Debit in the East Midlands, it charges 25.355p per kWh for electricity with a 50.204p daily standing charge, and 7.82355p per kWh for gas with a 28.455p daily standing charge. Rates vary by region. It has no exit fees, meaning you can leave at any time.

If you prefer price certainty, fixed tariffs are also available. In the East Midlands on 5 November 2026, Octopus 12M Fixed sets electricity at 28.9392p per kWh and gas at 9.650445p per kWh, with an exit fee of £50 per fuel. Octopus 18M Fixed sets electricity at 27.7633p per kWh and gas at 9.413355p per kWh, with an exit fee of £75 per fuel. Octopus reprices these tariffs often, so check your own quote.

For households with smart meters, Octopus also runs smart time-of-use tariffs such as Octopus Agile or Cosy Octopus. These offer lower rates during off-peak windows but call for active energy management. Tenant Power remains unique because it gives social housing tenants a simple, hassle-free percentage discount off standard rates without requiring them to shift their daily usage habits.

Tenants on Tenant Power are free to switch electricity suppliers if they choose. However, switching away from Octopus Energy ends your participation in Tenant Power, and you will lose the 25% to 30% unit-rate discount on your electricity bill.
