Save 30% off your electricity bill with Tenant Power and Castlehill Housing Association!
Octopus Energy and Castlehill Housing Association have teamed up to decarbonise homes and cut energy bills.
Tenant Power is a ground-breaking new tariff that could cut electricity bills for social housing tenants with solar and battery by up to £205* a year.
Tenant Power makes solar work for everyone. It's the UK's first tariff that shares the benefits of clean, green energy between tenants and landlords. Social housing tenants will save money on energy bills, while landlords generate a return for investing in renewables.

FAQs
Who can switch?
You can switch to Tenant Power as a new or existing Octopus customer.
How much will I pay?
You can get a quote for Flexible Octopus using the link above. Once you're installation is complete and we've connected to the solar and battery, we'll switch you onto our 'Tenant Power' tariff. The Octopus Tenant Power tariff gives you a 30% discount off SVT (standard variable tariff). Based on current SVT rates (Nov 25) that's a saving of £205 a year. You will still be required to pay the full electricity standing charge.
Flexible Octopus rates are reviewed every 3 months by all energy suppliers in line with Ofgem’s price cap. This ensures that when the wholesale price of energy is cheaper, you benefit from cheaper bills too. You’ll be notified by Octopus if Flexible Octopus rates change but you will still receive the 30% discount off your new rates.
Octopus remains the only large energy supplier to have never charged the full Ofgem price cap, collectively saving customers over £100 million pounds.
What if I am in debt with my current supplier?
If you have debt on your energy account that’s more than 28 days old, you won’t be able to switch. Once this has been cleared, you can apply to switch using the link above.
What if I have a pre-pay meter?
No problem, if you switch to paying your energy via direct debit you can join the tariff.
*For example, a 30% discount off SVT (based on price cap rates as of November 2025) would be a £205 saving a year
