A chaos project to silence the heat pump haters? I live for this shit

One morning in March, I got a message: Greg (yup, CEO Greg) wants a public dashboard showing the realtime data from our fleet of Cosy heat pumps. Oh, and it needs to be live before the end of next week. It’s exactly this kind of pressure that I and my colleagues thrive under. Let’s do this! Here’s a window into the beautiful chaos that followed as we made the Octopus Cosy Heat Pump Fleet Performance Dashboard. I’m Robin and I lead the Data Visualisation team at Octopus. I’ve been working here for just over four years and I’ve been involved in a number of projects that you might have seen, such as Balance Forecast, Wasted Wind, and my personal GB Renewables Map. This one — time-sensitive, highly transparent and something no energy supplier has done before — was right up my street.

A look back at our 2025 Octopus in Colour internship

As part of Octopus Energy's outreach to young talent from underrepresented groups, we run an annual Octopus in Colour Internship exclusively for young Black professionals, with the ultimate aim to increase diversity & representation in the world of energy and tech. In our 5th year running(!)* we had 30 brilliant interns across our London and Manchester offices, gaining practical experience in compliance and law, asset management, content creation, data science and more. Interns chose from a selection of 19 different departments and were with us for 8 weeks in total. After some training, they all got stuck into live project work, to give them a taste of what their role would look like full-time. Apart from socials (like bowling and games nights) and site visits to our wind farms and R&D centre in Slough, each intern also put together their own presentation which they gave in front of senior leadership, their mentors and the rest of the cohort in their final week - these were an absolute hit and included a mix of reflective run-downs of projects they'd been working on, and innovative new ideas for the business - the floor was theirs!

Heat pump with pink flowers

How two homeowners scored a heat pump with their mortgage (and how you could too!)

When you secure a new mortgage, the biggest milestone is usually finally getting your hands on the keys. If you’re lucky, you might get a “congratulations” card in the post. You certainly don't expect your lender to foot the bill for a brand-new, low-carbon heating system! But late last year, Lloyds Bank did exactly that. If you accepted your first illustration to take out a new mortgage or switch deals with them between mid-October and late November, they offered to foot the bill for a standard heat pump installation by us here at Octopus
