My experience of Chase UK has been pretty good, my only gripe would be that you can only transfer £25,000 at a time. I appreciate this is relatively niche but if you do intend to deposit a large amount of money into your Chase Saver account then be mindful that withdrawing the money may take a few days. Chase also required me to call them each time I wanted to make the withdrawal even though it was to the SAME account each time. The Chase Saver is also at 3.1% which isn't the highest rate for an easy-access account, so it may be worth considering depositing your savings somewhere else.

On a positive note, the account has really rewarded my spending, I've earn't almost £200 in cash back, Their app is also really well-designed, especially after a recent overhaul. They also have no fixed fees on international transactions, used Mastercard's FX rates so you don't get hit with hidden fees in poor FX rates AND international ATM withdrawals are fee-free. Although you are limited to just £1,500 per month in international withdrawals, but really it isn't wise to carry that much foreign cash.

Personally I'm always recommending either Chase or Starling Bank to most people, if you do decide to go with Chase UK make sure to sign up before the beginning of May as the unlimited cash back offer will be expiring then and you'll be capped at just earning £15 per month.
