Hi Steamy Tea. I guess you know the area well? What is this "gas" you speak of ?? ... 😉
Services "should be Ok" !
Unfortunately the gables will run North/South- although the house next door is the same and is doing well with PV on the west side.
Iceverge: design is currently being finalised for detailed PP.
I hoping to insulated and air tight well enough to get away with ASHP and a Log burn boost for the depths of winter, I'll probably go with a mix of PV and Solar Thermal/heat store if I can get it to look ok.
If anyone can suggest a better solution I'd be happy to consider anything...
