Article 4 Directions remove certain Permitted Development rights and rarely all. As per the above, unless there’s an online council source that makes clear where any Directions are then you probably are best calling the planning department. They aren’t that common as they are frowned on by government but there were quite a lot designated particularly in the 70s and 80s on new estates where councils tried to limit PD rights to protect neighbour relations.
Edit: Just had a quick Google and it appears Cheshire East designated a borough-wide Art4 Direction in 2019 to limit the ability to create Houses in Multiple Occupation from normal dwellings. There seem to be others in Conservation Areas. I’d speak to the planning department. NB, you also need to check Article 3 restrictions on PD rights. Must admit I don’t recall those from when I was a planning officer, but it was nearly 35 years ago.
