This week, Jeff, Alex and Dan are joined by Dr. Peter Rickaby, a man who should need little introduction to those who know the sector well, and to the listeners of our podcast, he's been on twice before.

To those less familiar with him, he's an expert in the sector, who's devoted a career to improving energy efficiency in the built environment in the UK with a particular interest in retrofit.

This week, rather than talk about a particular piece of work or technology, we wanted to talk about a slightly more esoteric subject: who can you trust? In other words, how difficult is to know what to do about anything. It's something we talk about amongst ourselves a lot, and presumably you our listeners find yourselves talking about much the same.

The challenge here can probably be best summed up by the endless heat pump debate, in which we're asked to often hold two contradictory and correct positions at the same time: every home can be heated by a heat pump vs. not every home is suitable for a heat pump. We thought Peter would be a great person to talk about it because of the length and breadth of his experience, and he's a great speaker.

We took in the housing market, heat pumps, hydrogen, retrofit, snake oil and more. In spite of our conversational meandering and rambling, we did actually manage to come up with, albeit a very short list, of people that we do think you can actually trust. Anyway, we hope you enjoy the conversation as much as we did.
