Inside our Cosy 6 heat pump factory

Our community Green home tech

Octopus Energy is already the biggest heat pump installer in the UK. With the launch of Cosy 6, we've become the first energy provider to make and install our own heat pump—and we're pretty pumped about it.

In this blog, we go behind the scenes of our Cosy 6 factory in Portadown, Northern Ireland to see where the magic happens and meet the people helping us make heating cheaper, greener and more efficient.

Introducing Cosy 6

A year ago, we launched Cosy 6 – a heat pump that has skyrocketed in success over the past 12 months. Now, we're building thousands more as people turn to greener energy systems to save on bills, cut carbon, and heat their homes efficiently.

This amazing surge in demand meant it was time to move out of the Octopus test centre and find a suitable home for our Cosy-6 factory. A place that could keep up with the pace of production, provide new and exciting job opportunities, and offer an unrivalled sense of community. (Because we're nothing without our people.) So we chose Northern Ireland.

Why Northern Ireland?

Northern Ireland is an amazing place with a rich history, but it hasn't always received the investment it deserves. We wanted to change that. By setting up our factory in Portadown, we're not just building low-carbon tech; we're helping to grow the local economy and create new job opportunities in a region with so much to offer.

"Nobody else is really doing what we're trying to do here. At the rate we're trying to do it. It's an exciting part of Northern Ireland"
Phil McVarnock, Production Manager

It all started in 2022, when we brought engineering genius Jason’s heat pump company, RED, into the Octopus family and in no time, we built and launched our very own Cosy 6 heat pump. Now, we're on track to produce 35,000 heat pumps a year and create 120 local jobs. But this isn’t just about numbers —it’s about making green, affordable heating available to everyone.

What's special about the Cosy 6?

The team at Portadown have developed the tech, design, and installation process for Cosy 6. It's all done in-house. Which means things can move fast based on real-time feedback from customers. This kind of integration is game-changing, and puts us at the forefront of advances in green energy tech. Something we're super proud of.

The Cosy 6 really is the complete package: a heat pump, hot water cylinder, straightforward controls, and up to four Cosy Pods to monitor your home's temperature and humidity. And we're pleased to say it's up to four times more efficient than a gas boiler.

"We're supplying the electricity. We're installing the product. We're producing the product. We're then controlling the product and looking after the product throughout its entire life cycle… that makes us different to all the competition"
Colin McKinstry, Head of Technical for Octopus heat pumps
