Octopus Energy

We’ve teamed up with Octopus Energy to integrate our Renatus retrofit design and specification with their brand-new Tenant Power tariff. Through effective fabric retrofit measures, coupled with low carbon, green energy solutions such as solar PV and battery storage, tenants can save on their energy bills and landlords can unlock a new revenue stream from exported power.

How it works

  • We assess your building fabric and energy systems to tailor a full retrofit package.
  • We design and specify the optimal number of solar panels and battery capacity for your property.
  • Certified installers fit RENATUS-approved measures in one coordinated project.
  • Octopus Energy registers the home on Tenant Power and connects the generation system to their smart metering network.
  • Tenants benefit from heavily discounted electricity, and landlords earn for any surplus energy sold back at peak times.
