How close can i build to my neighbours fence

We are looking at having a side extension just to widen the lounge and dining room (single storey). We're very early stages here, but how close can we get to that boundary? Also, how does this impact if we need to have scaffolding around the side for some reason?

"You can often build right up to your boundary (0m) for rear extensions with permission/rights, but for side extensions and most garden buildings (sheds, cabins), UK rules usually require at least 1 metre from the boundary, or 2 metres for taller structures"

"Hi Karen , I am sure you have to be 1 metre from the boundary , Im sure the council planning department will tell you exactly where you can build to ."
