Tenant Power is a natural extension of the Octopus ecosystem that Improveasy already operates within. It is the UK’s first energy tariff designed to let both tenants and property owners benefit financially from low-carbon technology installed in their homes.
It is available to housing associations, local councils, and social housing landlords. Tenant Power is built to deliver real financial returns for providers whilst bringing energy savings directly to tenants. Please note: this tariff is not available for standard buy-to-let or private rental properties.
Properties fitted with solar panels and a compatible battery system can generate and store their own renewable energy. Plus, tenants receive a discounted energy tariff, with savings of up to £200 per year compared to a standard variable tariff, while landlords receive payments for surplus energy exported back to the grid at peak times.
It’s a model designed to make investing in green technology commercially worthwhile, not just an obligation.
As an Octopus Trusted Partner and accredited Cosy Heat Pump installer, we are uniquely positioned to deliver the solar, battery, and heat pump installations that make Tenant Power possible.
That means social housing providers don’t just get access to an innovative tariff, they get a single, trusted partner who can survey, install, certify, and support the full technology stack required to unlock it.
