What we do
We're on a mission to power the planet with cheap, clean energy as quickly as possible.
You get fairly-priced tariffs today, while we help build a smart, reliable, low-carbon energy system for tomorrow.
Homegrown power for a stable britain
We need to move away from dirty fossil fuels from thousands of miles away and replace it with cheap green energy. At Octopus, we’ve already invested more than £6 billion in renewable generation.
Lobbying for a fairer system
The current system is broken. We are actively lobbying the government to decouple electricity prices from gas prices, ensuring that cheap green energy actually results in cheaper bills for you.
Low carbon technology
We’re the largest installer of heat pumps in the UK and we’re obsessed with making heat pumps and their running costs more affordable. We’re also supercharging homes with solar panels and EV chargers, creating a one-stop-shop that puts you in control.
Homes with zero-bills
In 2024, we kicked off a new mission: to build 100,000 Zero Bills homes by 2030. Homes that are fully powered by green tech - solar panels, heat pumps, and batteries - with zero home energy bills. It isn't some far-fetched dream, it's happening today. And we're leading the charge.
Cutting costs for social housing
We’ve launched a ground-breaking new tariff. Tenant Power is designed for social housing with solar panels and a battery. By offering a special discounted bill, it gives tenants cheaper electricity by harnessing rays on the roof, and benefits landlords too.
