Sorting out a new build. Which of the two would add the most value to a new house? We are only planning to live in it for a few years, so won't be able to recover costs for a Solar Power + Gas Booster system. If we were living in it forever, I would definitely go the latter.
How much are buyers swayed by Solar Power + Gas Booster systems? I think I'd rather spend the money saved in the ensuite and kitchen - it's the first place potential buyers look. My guess is it's the same as increased insulation rating - no value add.
Your opinions?
