Amending house extension plans

The house I've bought already has planning permission for a double storey extension. There's a few little changes I'd like to make to the plans. Do I need to get the plans updated and resubmitted before building starts?

"This depends on the changes you intend to do and property itself. Generally speaking you don’t need to update drawing for internal changes for planning non listed properties however BC drawings would have to be updated for approval."

"You would generally get away with internal changes or alterations, however, you’d be better off getting planning or seeking clarification for any external changes so as not get into problems with the council. So seek clarification or planning before building starts as if spotted by an inspector once building commences, you run the risk of having to pull down any alterations not in line with what has already been approved."
