Dropped into to a newly opened Energy Support Hub run by volunteers this morning to see what they had to offer. There was already someone in there bem...
@gunboatdiplomat A little more complicated. I have one small room that is entirely solid wall, one large room with one wall run that is about 15% soli...

@jamespa That’s a really interesting article. I’m a hostage to fortune with Octopus as computer says No. I don’t believe my house heat loss is as they...
