British Gas vs Octopus Energy vs Heat Geek vs EDF vs Aira vs OVO vs EON.Next vs Boxt

Mars · 2025-11-19T14:19:27Z

This week we brought together five of the biggest names in UK heat pumps, British Gas, Octopus Energy, Heat Geek, EDF and Aira, for one of the most telling conversations we’ve ever hosted. We tackled the big questions homeowners keep asking: Who actually delivers quality at scale? Are high-temperature systems helping… or causing a race to the bottom? What protection do you really have if something goes wrong? And with so many different models and promises, how on earth do you choose? What surprised us most? There was far more common ground than conflict.order to make this thread more encompassing, even though we didn't have OVO, E.ON Next or Boxt on the podcast, this thread is basically dedicated to discussing proposals and offerings from volume installers.

The difference between Octopus (£6,500) and Heat Geek installer (£18,500) was ridiculous - these are after the BUS grant. It wasn't even a complex install, the design had been done and paid for, and half that £18.5k was just for labour on a 4 day job. I know it feels a bit conspiratorial but charging £26k for a heating system install which requires no major renovation, just in-situ replacement of radiators, feels to me like someone is taking advantage of the fact 7.5k is available and inflating in other areas. I paid less than that for 25 triple glazed, Austrian manufactured windows with a typical 0.4u - 0.7u value, fitted and guaranteed for 10 years.

I'm struggling with an out-of-the-ordinary problem: a system that seems to be overheating when temps are mild but significantly overheating when it is cold, and yet not that inefficiently either! If it wasn't so hard to try and work in a 25c room or go to sleep at 24c I'd probably be quite happy. We all know heat loss calcs are critical but I don't know how a homeowner can reach an informed understanding on something that is quite complex. Both the heat loss reports I had where within 200w of each other and that gave me some confidence, which turns out to be a bit misplaced but if they'd given me the breakdowns and calcs I wouldn't know how to verify them for accuracy. How people decide when they have wildly disparate values I don't know.

At least my wife is warm for which I'm pleased beyond measure: my life wouldn't be worth living if it was the other way around 😀
