Thanks for the replies, much appreciated.
I managed to find UK ETF's which mach the ones I listed above and they all by Invesco
So XLU Utilities Select Sector SPDR Fund (USA issuer)
apears to be very similar in performance to Invesco Utilities S&P US Select Sector UCITS ETF (UK, has KIID, ok for ISA)
I have only checked the above pair but Invesco provide a matching etf for all sectors I listed.
