Download our Heat Pump Talk presentations

Big thanks to everyone who came to the packed-out Transition Town Lewes talk on Heat Pumps last month.


Special thanks to our speakers – local renewable energy expert Neil Williams and Ian McKay of sustainability consultants Deeper Green for their presentations – and to our installation specialists from DH Solar and OHM energy for all their practical advice for audience members.

As promised, Neil’s and Ian’s presentations are available to download below. As the talk was so well received, we’ll look to hold it again later in the year. If there’s anything in particular you’d like us to cover, let us know in the Comments below or email us at
