Thank you! Unfortunately, the UK is borderline not in the EU any more, and all these online brokerages require a NI number... I tried to use Interactive Brokers, which I heard was great for buying ETFs and index funds, but the interface was ridiculously complicated, and did not inspire trust.
Pretty straight forward.
The ongoing for the funds are 0.22%, the ISA platform 0.25% and the SIPP 0.3%
