It doesn't sound that high a spec new build chum, it merely sounds like all of the other mass produced houses.
I thought you had said you bought it from new, which would have given you some input into things and the extra's you'd require.
Love how you have assumed the spec based on the electrics in the garage. It was built by an independent developer and is nothing like you think so please dont assume. I have seen many new builds by the big guys, wouldn’t touch one.
I did buy it from new, but the houses were already built before they were sold.
This is all besides the point. Question was around regs of the garage not having a point of termination and protection with a fuse.
I could still quite easily add this to my snag list which was the question which has already been answered.
I am not sure why you consider this as an extra requirement. For me to have the garage on a unfused spur is bad practice.
