Octopus Energy has launched a smart heating system Cosy Octopus.

Founder of Octopus Energy Group Greg Jackson launched the heating system at the WIRED & Octopus Energy Tech Summit in London. It will be available from December.

It consists of the 'Cosy 6', Octopus' new heat pump; 'Cosy Hub', a home controls system; 'Cosy Pods', room sensors; a bespoke smart tariff; and the award-winning Octopus 5-star service.

'Cosy Octopus' is free for homes that don't need any work to fit the system after the Boiler Upgrade Scheme (BUS). Homes that need adjustments – such as new radiators, piping or a hot water tank – will get the system from around £3,000 after the grant.


The system will enter the market with a 6kW heat pump – aimed at a typical three-bed UK home – with more and larger models following over the next six months.

'Cosy 6' is Octopus Energy's first heat pump built entirely in-house. It was designed by Dr Jason Cassells, CEO of Octopus-acquired Renewable Energy Devices (now known as Octopus Heating), and manufactured in Craigavon, Northern Ireland, and has six patent applications pending.

The home controls system 'Cosy Hub' and 'Cosy Pods' were developed by a team in London led by electrical engineer Derya Robinson.

Powered by Octopus' technology platform Kraken, the Cosy eco-system works seamlessly to offer the best performance at the cheapest and greenest times, allowing customers to save money on heating bills without compromising on comfort.
