Integrated will do it as part of single engine phase, modular will do it post PPL before CPL. Every summer (and this one was no exception) I have panicked phone calls from students trying to do a night rating in July / August having days to go before starting a CPL and wondering why they can’t find an airfield / instructor / low cost way of doing it!
Yesterday I was talking to a guy who has a PPL and is working towards a CPL/IR and doing his 14 exams (airline pilot career).
He was saying something about the night flying being done as a separate part, and sent me this
I know you can have a day-only IR (this was a UK under the table option for about 15 years and is now official under EASA FCL) and presumably you can have a day-only CPL. Obviously these would be useless in practice. At which point do UK ATOs do the night flying time?
