Octopus Energy is developing the Cosy Cooler, an add-on designed to provide room cooling through existing Cosy heat pump pipework. The company says it is aiming for a 2027 launch and an estimated retail price of £500–£600; performance, final pricing and availability have not been confirmed.
Octopus Energy is developing the Cosy Cooler, a room-cooling add-on intended for homes that already have the company’s Cosy heat pump system. The unit is planned for launch in 2027 and is expected to cost around £500–£600, according to a report by Cooling Post; Octopus has not yet provided confirmed retail specifications or a final launch date in the supplied material.
The cooler is designed to connect to the existing heat pump pipework, rather than operate as a separate conventional air-conditioning system. Octopus says this approach could make the add-on less expensive than buying a separate air conditioner and allow installation without major building work. The company’s reported estimate is about three hours to install, although that is not a confirmed installation guarantee.
Cooling Post reports that the prototype removes heat from indoor air through a heat exchanger connected to the home’s radiator loop, which is maintained at a reported 18°C. The collected heat travels through the heating pipework and is rejected outdoors by the Cosy heat pump. This describes the planned operating arrangement; the report does not provide independent performance testing or measured cooling output.
The system could cool one room, or operate two to three units at once across separate rooms, depending on the Cosy heat pump model. Based on the current prototype, the cooler is expected to measure 722mm high, 430mm wide and 358mm deep and weigh about 28kg. Those dimensions may change before a production version is released.
Cooling Without a Separate AC System
If delivered as described, the Cosy Cooler would give some households with an existing Cosy heat pump a way to add room cooling without purchasing a separate air-conditioning system. The proposed connection to existing pipework could also reduce the amount of new installation work, though the unit would still need to be fitted and integrated with the home’s heating equipment.
The idea addresses a practical limitation for heat pump owners: a system installed primarily for heating does not automatically provide the kind of room-by-room cooling described for this add-on. A reported price of £500–£600 would make the offer easier to compare with separate cooling equipment, but the total cost and value will depend on installation charges, compatibility and how well it cools a room. Those details are not established by the current report.
The proposed operation also relies on the outdoor heat pump to carry away heat removed indoors. That makes compatibility with the particular Cosy model central to how many rooms can be cooled at once. Octopus’s reported estimate of two to three units is model-dependent, not a claim that every installation will support that number.

Designed Around Existing Cosy Pipework
The development is being presented as an add-on to Octopus Energy’s Cosy heat pumps, not as a standalone cooler for homes without that system. The reported design uses the heating pipework and outdoor heat pump already associated with the Cosy setup to move heat out of a room. That intended integration is the basis for Octopus’s claims about lower cost and avoiding major building work.
Cooling Post describes the Cosy Cooler as a prototype and says it is British-engineered. Its report gives a planned launch year, indicative price and estimated installation time, but does not include a detailed specification, independent test results or confirmation that every existing Cosy installation will be compatible. The published dimensions likewise describe the current prototype, not necessarily the final product.
“The Cosy Cooler is expected to retail at around £500–£600.”

Price, Compatibility and Cooling Output
The product remains in development, and the supplied report does not confirm a specific launch date within 2027, a final retail price or when orders will open. It also does not state whether the £500–£600 estimate includes installation, or whether installation costs will vary by home.
Important technical details are still missing, including the unit’s cooling capacity, expected energy use, noise levels and how room temperature would be controlled. The source does not provide independent measurements of cooling performance or explain how the system would behave in different weather conditions. The number of supported rooms is described as dependent on the heat pump model, but a compatibility list is not available.
It is also unclear whether the prototype’s reported dimensions and weight will carry over to the consumer model. Octopus’s claims about cost, installation time and operation should be treated as development estimates until final specifications and product testing are published.

Final Specifications Before Launch
Octopus is targeting a 2027 launch. Before then, prospective buyers will need details on the final price, installation requirements, Cosy model compatibility and the cooler’s tested performance. The company has not announced a confirmed release date in the available report.
Any decision by a current Cosy owner will depend on those details, particularly the installed cost and how many rooms a system can cool. Until Octopus publishes final product information, the reported price, three-hour installation estimate and prototype dimensions remain provisional.

Key Questions
What is the Octopus Cosy Cooler?
It is a planned cooling add-on designed to connect to the pipework of an existing Octopus Cosy heat pump system. It is still in development.
When is the Cosy Cooler expected to launch?
Cooling Post reports that Octopus is targeting 2027. No exact launch date has been confirmed in the source material.
How much is it expected to cost?
The reported expected retail price is around £500–£600. A final price, including whether installation is extra, has not been confirmed.
Can it cool more than one room?
The reported design could run two to three units across different rooms, depending on the Cosy heat pump model. Octopus has not supplied a compatibility list or final technical specifications.
How does the add-on remove heat?
According to the report, a heat exchanger transfers heat from indoor air into the radiator loop. The heat then travels through the pipework and is rejected outdoors by the Cosy heat pump.
