Correct - I meant they need they need to be UK-Reporting ( I think) to be ISA compliant. Youāll notice āISA Compliantā and āSIPP Compliantā on a lot of ETF factsheets for UK customers. Iām assuming (and have noticed its true on any Iāve looked at) that UK reporting = ISA compliant.
You are of course free to buy non-UK reporting in GIA, and deal with the bigger tax bill.
