Is there a U.K. based broker or bank that allows US ETF investment?

Hi all

I am a HK based investor and hold a large US listed ETF portfolio. I am currently planning a permanent move to the U.K. and thinking of transferring my stocks to the U.K.

I would like to do so without liquidating my portfolio but it seems like the U.K. has very few if any brokers that will take US listed ETFs meaning I may have to cash my portfolio and buyback the U.K. listed equivalent.

Any major risks in cashing my 5% gain and buying back later say a week later?

Thabks !
