Many years ago my father built a garage and it took him possibly a couple of years to fix guttering. The principle reason was to get out of paying increased rates in those days. This was a build wasn't rated until it was signed off. Eventually because it was in use he capitulated.
However with Part 'P', what's to stop a notice to include rewire, adding of additional circuits, circuits to (unbuilt) outhouses and sheds etc with the intention of never "finishing" the work?
Is there a time-limit for the completion of work?
When sold it would be up to the new owners to choose whether to have the work "finished" or inspected.
Where am I going wrong?
